Resource 1: Winogradsky Columns

Building and observing Winogradsky columns are a great way to give students a close-up look at how life functions. Here’s everything you’ll need to make the columns and make them work for your classroom.

Resource Type
Instructions (text and video)

Teaching Notes

  • I introduce my previously made Winogradsky column stuffed with food (paper, penny, nails, and egg yolk), then have each student build a Winogradsky column using the most fine-grained, natural, “non-live” media they can find (and checking with me on the definition of “natural”—it’s pretty expansive) in a big test tube. They can use school dirt, mud, beach sand, concrete mix from the sidewalk, or something else, then set it up, top it with water and a cap (aerated), take photos, and leave it in the sun for later. Can we find, in our solar system, evidence of life that is not on Earth? That’s what we’re going to try to figure out.
  • You can make mini-Winogradsky columns in large test tubes.
  • Return to look at the Winogradsky columns after a few weeks or months, preferably after doing other activities on the traits of life and life that is not on Earth. Why do we assume there is life away from Earth? Because there’s lots of it here, even in arid, “dead,” media, under the right conditions. So let’s come up with a lowest-common-denominator definition of what life looks like so we can recognize it when we see it. What’s the absolute minimum of general conditions we need to find life? I make sure we get gradients (of pH, gravitation, light, temperature, ionizing radiation, phase change thresholds, specific elements or minerals, pressure, solid templates for liquid mixes, etc., specifically mentioning black smokers and cold seeps, clay and clay brines, and the various coral types) and put in a plug for fluids (instead of solid-state conditions) and that life changes its environment, but any definition they settle on, they can use. Students will continue to work on their definitions throughout this project, so they need a few pages at the start of this lab in their lab books where they can write their definitions and periodically revisit them to reexamine their ideas and assumptions.

Resource 2: Drake Equation Worksheet

Introduce students to the Drake Equation and give them a chance to fill in the blanks. The Drake Equation is an attempt to quantify the likelihood of life in the universe.

Reading and Worksheet

Teaching Notes

  • When Drake initially created the equation, a number could be estimated for only one of the variables. Now we have decent data on three of the variables, but getting data for this equation is a work in progress.
  • Give one worksheet per student, but have them work together. Discuss as a class which ideas are the best-supported.
  • You may want to review heavy elements in astronomy and briefly talk about generations of stars and how heavier elements are made.

Resource 3: SETI Worksheet

Introduce students to SETI, the radio search for extraterrestrial intelligence, and prompt them to think about the vocabulary of astronomy and how it reflects political, physical, and cultural trends.

Reading and Worksheet

Teaching Notes
The concept of “orders of magnitude” is very important in astronomy. This might be a good place to insert an activity or lesson on that concept.


Resource 4: Why Is Stuff Where It Is?

Explore the ways in which energy and resources (in the form of equipment, money, time, locations, and lots of very intelligent people) can change location and become concentrated due to environmental changes (in the form of WWII for this activity.)

Resource Type
Reading and activity

Teaching Notes

  • Why are things in the places they are? This activity uses the example of SETI being in Mountain View to try to answer this question. Do the activity and keep those maps (posted, if possible) because you’ll be referring to them later. Introduce the Pace Layers and discuss which Pace Layers were involved. It’s good to spend some time talking through other examples with the Pace Layers, as they will be coming up again later. Remember, there’s nothing absolute or infallible about this organizing idea; different people could argue for different layers or different orders of layers or different arrow lengths and directions. I tell students that I disagree with the idea that nature operates at the slowest pace because a large number of natural phenomena can happen very rapidly (insect evolution with insecticides, changes when a tipping point is crossed, weather).
  • The connection between this activity and the rest of the unit appears trivial at first, and it should. It should seem as if exploring how SETI ended up in California is a sidebar activity. It’s only toward the end that they should begin to understand that humans respond like all other organisms to changes in environment, and that this macro-example might be a good framework for looking for microscopic life. We used large paper maps and put them high on the wall, side by side. Projected overlays or transparencies might be interesting to try as well.
  • Some of the scientists and engineers were quite young and worked at Los Alamos pre-PhD, and some were women who weren’t going to be able to get a PhD or who were focused more on engineering and didn’t need (at that time) a PhD to get work. Each case like this is listed in the PhD column by “had just started” or “B.A.” or “B.S.”
  • Interesting things to note, and help students discover: The After careers of the women were clearly different from those of the men. The After careers of the African-American men were clearly different from that of the non-African-American men. There is a clear East Coast/West Coast split by age (younger going west, older going east.) And please don’t skip the looking up and talking through information on each one of these people—there are a few spies, there’s the first person to die from an atomic weapon, and more to be discovered.
  • If you find any information on Frances Dunne, Mary Ford, Thelma Northrup, or Jane Roberg, please add it to the list!
  • An extension pattern to pursue, or to bring up later, is that the Manhattan Project happened in the 1940s. Twenty years after that, we have the space program. Twenty years after that, we have the computer revolution. Twenty years after that, we have the biotech revolution. Why? Were these the results of resources and people being concentrated in the same places at the same time?

Resource 5: Life on Other Planets

Get students thinking about the problems with looking for intelligent life from earth with this short article.

Resource Type
Article

Teaching Notes

  • So, does SETI answer the question about life that is not on earth? Assign this reading as homework, then discuss (and define terms and analyze his argument) in class. But what if the question and method are too narrow? What if we didn’t worry about intelligent life and just looked for life—as a first step, instead of jumping straight to step nine?
  • You can have an interesting discussion by telling the students, “This was published in 2012; has anything in the article changed since then?”
  • This is one possible place to insert a history of the Earth-scaling activity. I like to have students work together in large groups (whole class, when possible) and make the biggest possible scale at school—often the length of the football field plus the track on either side. Here's a nice, simple timeline where they’ve done everything for you.

Resource 6: Define Life

Give students a set of different definitions of life to sort, organize, and analyze with the guidance of a worksheet and a “guided walking tour” of the results.

Resource Type
Activity worksheet, activity cards, activity key

Teaching Notes

  • Students will need to cut the cards apart.
  • After the activity, students do a guided tour of their organizing methods and discuss as a class. Then give them the answer key and discuss whether that changes their organizations or their personal definitions and why. Please feel free to update the first two definitions and add more to the list, but I strongly suggest keeping the older and the non-biology definitions, as it makes the discussion more interesting and opens possibilities for the students when we move off-planet.
  • This activity takes two full days for discussion and looking things up, but it's lively and worth the time.
  • End with reading the Carol Cleland quote at the end of the key. By the time you read it, students will already have arrived at some of what she says, and this will nudge them farther in their thinking.

Resource 7: How Did Life Start?

Investigate the boundary between the living and the non-living, including seven different theories for how life began.

Resource Link

Resource Type
Internet Article

Teaching Notes

  • How do we think life started? Read and discuss “7 Theories on the Origin of Life.” Refer to their definition of life as a work in progress and compare to the various ideas for life’s origins. Include the idea that there isn’t a hard-and-fast distinction between life and non-life when looking at a wide variety of stuff and not just individual organisms. For example, is a star alive?
  • The Community Clay idea is really, really interesting. It works with deep-sea vents, it works on a world covered in ice…I think we’ve got a winner here.

Resource 8: Can We See Life At a Distance?

Get a long view on the search for life on earth from space and review some chemical reactions that may be of interest.

Resource Link

Phil Plait, Ellen Koivisto

Resource Type
Short article, worksheet, list

Teaching Notes

  • How could you hunt for signs of life off of this planet, given your specific definition of what life does? What are some clues you could look for or test for? Is there evidence of life causing changes visible over interplanetary distances? Pass out and have students read “Poisoned Planet” by Phil Plait, then answer questions on the Evidence of Life worksheet, with reference to the Some Chem Rxns Of Interest sheet.

Resource 9: Tools For The Job

What tools do we have to hunt for life that's in our solar system, but not on our planet?

Resource Link

Resource Type
Lab activity and worksheet

Teaching Notes

  • To do this lab activity, you’ll need spectroscopes, spectrum tubes, and spectrum tube power supplies or other ways to access spectra of various elements and molecules. I had my students use their own cell phones. You’ll need a candle and matches and some sort of nonflammable surface to put them on. I suggest having a few rock and mineral guide books around, in addition to streak plates (the unglazed, white backs of tiles work), some dilute hydrochloric acid in dropper bottles (1M will get good reactions), rock or mineral samples to test (chalk, limestone, mudstone, quartz, some rocks lying around the school, or you can ask the students to bring some in), a Mohs hardness scale and maybe some items on the scale, and goggles.
  • The Mohs lab is included for your information, but if you haven’t done a Mohs lab before, or would like that part more formally structured, this is a very good one.

Resource 10: The Search Begins

Assign students to locations in the solar system to start their search for life—then let them look.

Resource Link

Resource Attribution
Ellen Koivisto, Desilu Productions, Terry Bisson

Resource Type
Worksheet/project guidelines, TV episode (~50 minutes), short story, worksheet

Teaching Notes

  • Draw locations from a hat: Mercury, Mars, the sun’s photosphere, Europa, Io, Venus, Titan, Neptune, a regular-period comet (Main Belt might be easiest), the outside of the International Space Station, Ceres, the Pluto-Charon system, and interplanetary space. Let students talk in groups, then show them “The Devil in the Dark.” Follow the episode with “They’re Made of Meat,” by Terry Bisson, read aloud as a class.
  • I picked locations for the students to draw that would stretch their ideas of life and/or prove a set of conditions in which life can’t exist. The third possibility is that there just isn’t yet sufficient data one way or the other (this was especially true of the outer ice giants and their moons). The most resource- and boundary-rich locations are, to our current understanding, the most likely to have life.
  • Try reading “They’re Made of Meat” with two readers, since it’s more a script than a short story. If you have people who can act but aren’t good sight-readers, maybe give them the story a day in advance.
  • Tidal locking and general orbit information can be useful here. If you haven’t done anything with Kepler’s Laws yet, this is a good place to do those. I’ve included three Kepler activities.
  • If you do the Kepler’s Law activities, talking about Molniya orbits and how and why they were developed is interesting and potentially useful for future engineering projects.

Resource 11: Remote Sensing and Your Location

Bring students along on their search for life—teach them about remote sensing and how it can be a tool for their work in their particular location.

Teaching Notes

  • When I taught this unit, I invited NASA scientists to visit and talk about remote sensing with my students. However, the Remote Sensing Lab packet covers the same material.
  • Students begin by reading a one-page article from popular science magazine (“How Close to Finding Alien Life?” Byrd, 2015), then read the studies cited in the article, depending on how relevant each study is to the group’s work. The article “NASA Spots Signs Of Life…On Earth” is a must-read.
  • These articles are a good start for the kind of materials students are going to be sifting through and searching for.
  • The spectra of selected microbes, presented in the surface biosignatures study (Hegdea, 2015), turned out to be incredibly important. The authors are very reachable.

Teaching Notes

  • To do independent research, students will need access to various agency internet sites (NASA, ESA, CNSA, CRISP, COSPAR, ISRO, JAXA, the Russian Federal Space Agency, the Soviet Space Program [especially for Venus], SANSA), periodicals, and journals.
  • From here on, groups will primarily work on their own locations, with periodic whole-group and similar-situation check-ins, colloquia, and requests for information (to put it more clearly, there will be groups with similar situations who may share resources or bounce ideas off each other more often). Individual needs drive what happens in class and out.
  • Students work in their groups on answering the questions, with frequent breaks to post questions to the whole group, recommend resources, or share data.

Resource 13: Publication

Prepare students to learn how to write up their studies for possible publication.

Teaching Notes

  • Student groups work on refining their data searches, obtaining information, and writing up their papers. The Potential Publication Sources list gives them an idea of how much is out there—it is nowhere near exhaustive. The sample abstract is the prompt to have each group write its first-draft abstract; this will focus their research and writing. The Data Analysis Worksheet helps with making sure the data is relevant and that it is evidence for their claim. Pass out the Scientific Citation Formats info and have the groups work through, and turn in, each section before they can start work on the next section, Scientific Paper Worksheet Parts 1, 2, and 3. If Part 1 requires rewriting, it must be done before going on to Part 2, etc. Each group should expect to write multiple drafts of each section of their study. There are frequent paper swaps, where groups will swap, read, critique, question, and discuss papers. There are also frequent colloquia with presentations of work to date or asking for assistance with data or missions.
  • Groups with insufficient data (mostly due to mission number and type) will be designing the missions necessary to obtain the data they need, and justifying the need for these missions by making their arguments for life in a particular location as strong as possible. There are remotely operated, free, Earth-based telescopes that students can call up observations on; this information was presented to my students, but none of the groups could get the data they needed this way.
  • We found writing the abstract first gave the groups focus, and as they worked, they were constantly rewriting it.
  • One publisher demanded a hypothesis section, which that group put together when it was demanded.
  • One group’s publisher had its own format for citation, especially of tables and graphs. Impress upon the students that, if they need to include images, data, or figures from other papers, they must get permission from the authors of the papers (or copyright owners, if they are different).
  • Students present their work in poster talk sessions. They also answer questions, especially about how to advance the research, whether their chosen approach is a promising one to follow up on and/or whether there are variations on the research approach to recommend, whether there have been connections made and to whom, and publication stories to be told. We were lucky enough, at this point, to arrange a field trip to NASA Ames, where we got to spend time in a remote sensing lab, among other things.

Science and Engineering Practices

All eight are required.

Disciplinary Core Ideas

Earth’s Place in the Universe

ESS1.A The study of stars’ light spectra and brightness is used to identify compositional elements of stars, their movements, and their distances from Earth. (HS-ESS1-2),(HS-ESS1-3)

ESS1.B Kepler’s laws describe common features of the motions of orbiting objects, including their elliptical paths around the sun. Orbits may change due to the gravitational effects from, or collisions with, other objects in the solar system. (HS-ESS1-4)

Earth’s Systems

ESS2.B: The radioactive decay of unstable isotopes continually generates new energy within Earth’s crust and mantle, providing the primary source of the heat that drives mantle convection. Plate tectonics can be viewed as the surface expression of mantle convection. (HS-ESS2-3)

ESS2.C The abundance of liquid water on Earth’s surface and its unique combination of physical and chemical properties are central to the planet’s dynamics. These properties include water’s exceptional capacity to absorb, store, and release large amounts of energy, transmit sunlight, expand upon freezing, dissolve and transport materials, and lower the viscosities and melting points of rocks. (HS-ESS2-5)

ESS2.D:

  • The foundation for Earth’s global climate systems is the electromagnetic radiation from the sun, as well as its reflection, absorption, storage, and redistribution among the atmosphere, ocean, and land systems, and this energy’s re-radiation into space. (HS-ESS2-2)(HS-ESS2-4)
  • Gradual atmospheric changes were due to plants and other organisms that captured carbon dioxide and released oxygen. (HS-ESS2-6),(HS-ESS2-7)
  • Changes in the atmosphere due to human activity have increased carbon dioxide concentrations and thus affect climate. (HS-ESS2-6),(HS-ESS2-4)

ESS2.E Biogeography The many dynamic and delicate feedbacks between the biosphere and other Earth systems cause a continual co-evolution of Earth’s surface and the life that exists on it. (HS-ESS2-7)

Earth and Human Activity

ESS3.A

  • Resource availability has guided the development of human society. (HS-ESS3-1)
  • All forms of energy production and other resource extraction have associated economic, social, environmental, and geopolitical costs and risks as well as benefits. New technologies and social regulations can change the balance of these factors. (HS-ESS3-2)

ESS3.B Natural hazards and other geologic events have shaped the course of human history; [they] have significantly altered the sizes of human populations and have driven human migrations. (HS-ESS3-1)

From Molecules to Organisms: Structures and Processes

LS1.A: Structure and Function

  • Systems of specialized cells within organisms help them perform the essential functions of life. (HS-LS1-1)
  • All cells contain genetic information in the form of DNA molecules. Genes are regions in the DNA that contain the instructions that code for the formation of proteins, which carry out most of the work of cells. (HS-LS1-1) (Note: This Disciplinary Core Idea is also addressed by HS-LS3-1.)
  • Multicellular organisms have a hierarchical structural organization, in which any one system is made up of numerous parts and is itself a component of the next level. (HS-LS1-2)
  • Feedback mechanisms maintain a living system’s internal conditions within certain limits and mediate behaviors, allowing it to remain alive and functional even as external conditions change within some range. Feedback mechanisms can encourage (through positive feedback) or discourage (negative feedback) what is going on inside the living system. (HS-LS1-3)

Ecosystems: Interactions, Energy, and Dynamics

LS2.C: Ecosystem Dynamics, Functioning, and Resilience

  • A complex set of interactions within an ecosystem can keep its numbers and types of organisms relatively constant over long periods of time under stable conditions. If a modest biological or physical disturbance to an ecosystem occurs, it may return to its more or less original status (i.e., the ecosystem is resilient), as opposed to becoming a very different ecosystem. Extreme fluctuations in conditions or the size of any population, however, can challenge the functioning of ecosystems in terms of resources and habitat availability. (HS-LS2-2),(HS-LS2-6)
  • Moreover, anthropogenic changes (induced by human activity) in the environment—including habitat destruction, pollution, introduction of invasive species, overexploitation, and climate change—can disrupt an ecosystem and threaten the survival of some species. (HS-LS2-7)

Motion and Stability: Forces and Interaction

PS2.A: Forces and Motion

  • Newton’s second law accurately predicts changes in the motion of macroscopic objects. (HS-PS2-1)
  • Momentum is defined for a particular frame of reference; it is the mass times the velocity of the object. (HS-PS2-2)
  • If a system interacts with objects outside itself, the total momentum of the system can change; however, any such change is balanced by changes in the momentum of objects outside the system. (HS-PS2-2),(HS-PS2-3)

PS2.B: Types of Interactions

  • Newton’s law of universal gravitation and Coulomb’s law provide the mathematical models to describe and predict the effects of gravitational and electrostatic forces between distant objects. (HS-PS2-4)
  • Forces at a distance are explained by fields (gravitational, electric, and magnetic) permeating space that can transfer energy through space. Magnets or electric currents cause magnetic fields; electric charges or changing magnetic fields cause electric fields. (HS-PS2-4),(HS-PS2-5)

Energy

PS3.A: Definitions of Energy

  • Energy is a quantitative property of a system that depends on the motion and interactions of matter and radiation within that system. That there is a single quantity called energy is due to the fact that a system’s total energy is conserved, even as, within the system, energy is continually transferred from one object to another and between its various possible forms. (HS-PS3-1),(HS-PS3-2)
  • At the macroscopic scale, energy manifests itself in multiple ways, such as in motion, sound, light, and thermal energy. (HS-PS3-2) (HS-PS3-3)

PS3.C: Relationship Between Energy and Forces

  • When two objects interacting through a field change relative position, the energy stored in the field is changed. (HS-PS3-5)

PS3.D: Energy in Chemical Processes

  • Although energy cannot be destroyed, it can be converted to less useful forms—for example, to thermal energy in the surrounding environment. (HS-PS3-3),(HS-PS3-4)

Waves and their Applications in Technologies for Information Transfer

PS4.A: Wave Properties

  • The wavelength and frequency of a wave are related to one another by the speed of travel of the wave, which depends on the type of wave and the medium through which it is passing. (HS-PS4-1)
  • Information can be digitized (e.g., a picture stored as the values of an array of pixels); in this form, it can be stored reliably in computer memory and sent over long distances as a series of wave pulses. (HS-PS4-2),(HS-PS4-5)
  • [From the 3–5 grade band endpoints] Waves can add or cancel one another as they cross, depending on their relative phase (i.e., relative position of peaks and troughs of the waves), but they emerge unaffected by each other. (Boundary: The discussion at this grade level is qualitative only; it can be based on the fact that two different sounds can pass a location in different directions without getting mixed up.) (HS-PS4-3)

PS4.B: Electromagnetic Radiation

  • Electromagnetic radiation (e.g., radio, microwaves, light) can be modeled as a wave of changing electric and magnetic fields or as particles called photons. The wave model is useful for explaining many features of electromagnetic radiation, and the particle model explains other features. (HS-PS4-3)
  • When light or longer wavelength electromagnetic radiation is absorbed in matter, it is generally converted into thermal energy (heat). Shorter wavelength electromagnetic radiation (ultraviolet, X-rays, gamma rays) can ionize atoms and cause damage to living cells. (HS-PS4-4)
  • Photoelectric materials emit electrons when they absorb light of a high-enough frequency. (HS-PS4-5)
