In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.

In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.

In this ecology activity, learners make a model water-based ecosystem called a terraqua column. The column (in a large soda bottle) includes pond water, duckweed, sand or gravel, and small snails.

In this outdoor activity, learners use artificial bees and paper models of flowers to find out how bees transfer pollen from one flower to another.

In this activity, a group of learners work collaboratively to design and construct a paper model showing the evolution of an environment through multiple stages, from prehistory through the modern cit
