Investigate the living world.
Sometimes life is hard to observe, because it’s too tiny or fast or is hidden underground or in the ocean. Discover what you’ve been missing: use scientific tools to investigate living things of different sizes, the ecosystems they inhabit, and the processes they share.
A Cell in Motion
Turn the crank and watch a moving cell model. Different parts of the cell extend and retract, and the cell’s internal bulk sometimes shifts from one area to another.

Confused Sea
Air blowing over the surface of water inside a large Plexiglas hemisphere mimics the action of the wind over the ocean by generating waves. The waves slowly change and build until the entire volume of water is circulating as one wave. Viewers can adjust the speed of the air blower and influence the building of the waves.

Energy from Death
A decaying carcass makes a perfect meal for an assortment of scavengers, including the dermestid beetles you can see in this exhibit. As they feast on these carcasses, the dermestid beetles and their larvae get their energy and nutrients from the dried flesh, skin, and other tissues.
