GRADUATE SUBMISSION:
Donna Lawrence and Wanda Rinker:
"Three Kinds of Hands-On Science with Ice Balloons"
District
Lawrence Township,
West Windsor, Plainsboro: New Jersey
Team Members
Donna Lawrence and Wanda Rinker are science resource teachers with full-time classroom
responsibilities.
Purpose of Workshop or
Activity
The activity described below (3 kinds of hands-on science with ice balloons)
took place on the first day of a one week inquiry teacher workshop. The purpose
of the week is to introduce teachers to what inquiry is all about, including
questioning, constructivism, assessment, communicating results, and what inquiry
looks like in a classroom.
The main objective of the 3 kinds of hands-on science activity was to put everyone
on the same page so when we mentioned inquiry science, everybody had the same
mental picture. Not that the other ways were not good, but we wanted teachers
to distinguish them from the inquiry part.
Audience
150 elementary teachers and administrators
Description of Activity
Here is a brief description of how we did our "Three kinds of Science " (Foam)
segment in New Jersey. We used ice instead of Foam as a material. We used ice
balloons (frozen water balloons) as the "inquiry model". We investigated them
in a similar manner to what we did at the Exploratorium in April. (The materials
were: ice balloons, buckets of water, salt, sugar, food coloring, nails, plastic
plates, and hammers) We used the facilitating techniques of the inquiry activity
in "foam".
For the challenge activity, we used ice cubes. The Challenge: Design a method
to put a hole all the way through an ice cube. Parameters: Do not break or crack
the cube. If you do, you must get another cube and start over. There should be
as little melting as possible. You may use only the materials provided at the
materials center. (large ice cubes, sugar, salt, nails, food coloring, hot and
cold water, plastic plate). You will have 10 minutes. Again we facilitated this
in a similar manner to the "foam" challenge activity.
For our guided activity, we gave everyone fresh cubes. We made up a worksheet
that included these questions:
1.) Observe your ice cube. Draw and describe its shape, size, and general appearance.
2.) Bring your finger near all sides of the cube's surface. Do you feel any changes
in temperature from top to bottom? From side to side?
3.) Allow the cube to sit for several minutes. Observe carefully. Describe any
changes that you notice.
4.) Where does the melting seem to occur? At the sides, top, or bottom?
5.) Take two fresh cubes. Place one in a plastic baggie and leave the other in
an open drinking glass. Observe the changes over time.
We did the ice balloons activity in groups of four. We did the challenge and the
guided activity in pairs.
Due to our numbers (150 people), we split the group up into 5 groups of 30. Each
group went to a different room. Two staff Developers worked with each group of
30. Each room proceeded the same way so the participants had very similar experiences
which we could refer back to all week. As an instructional team, we decided on
the order of inquiry, challenge, and then guided. Due to the nature of our set
up, we did not rotate through stations. Everyone did the same activity at the
same time. We used the same type of questions and end of the activity processing
discussion that we used at the Exploratorium in April. The discussions were very
rich. The participants really liked this activity, and it really brought home
the difference between the types of hands-on science. I would have to say that
it was a success.
Schedule
2 1/2 hours total
inquiry part: 40 minutes
challenge part: 15 minutes
guided part: 15 minutes
Write in journals on the following prompts: 20 minutes
"What are the similarities and differences between the 3 approaches?"
"Which approach did you like best?"
"Which did you like least?"
"What issues did doing this activity raise for you?"
Small group discussion: 40 minutes
How the Activities Support the Purpose:
Got people involved and excited on the first day so it would make an impression.
Gave people a concrete picture of inquiry and other approaches so they could refer
back to them in discussions later during the week.
Gave them something to look back on.
Questions and Feedback:
How did it go?
People liked the inquiry part. They didn't want to stop.
Goal oriented people loved the challenge.
People were so bored by the guided activity that some didn't even want to fill
in the worksheet.
We had to train the trainers. We were the only ones who had experienced the activity
so we had to do the activity with the trainers first. They were so nervous when
it came to facilitating the activity that we had to write a script of what to
say and when to say it. It went very well. During the discussions, if the trainers
were anxious about getting conversations going, they could simply ask people to
read from their journals about the prompts.
What surprised you?
How well received it was, and how much people referred to the activity later in
the week without prompting. How big of a need it seemed to fill.
Linear thinkers were worried that we put materials out but didn't tell them what
to do with them in the inquiry part. People took three times the materials they
needed just because they were there (just like children) until they realized they
didn't need them.
We found that people liked to peel their own balloons.
What pleased/disappointed you?
We would like to refine the challenge activity to make it a bit more open ended.
Would you do it different next time? How?
Would use clear plastic tubs instead of buckets so we could see the iceballs float.
Might try it with parachutes instead next time in order to not have to freeze
and transport so many ice balloons.
What would you like feedback on from the group?
Would like feedback on improvements in the challenge activity. It lacked options.
There seemed to be one best way to do it (salt and twist a nail). We would like
to find a challenge that has more than one way to solve it.
