In this activity, pairs of learners model how scientists use craters to determine the ages of lunar surfaces. One partner keeps time while the other creates a painting for the other to interpret....

Learners explore capillary action in plants (such as plants ability to move water from roots to leaves) in an investigation called Paper Blooms. Placing paper flowers in water mixed with food...

In this activity, learners make cool boxes out of old (or new) greeting cards or postcards. Before making the recycled boxes, learners can practice making boxes from grid paper while learning about...

In this activity with several mini experiments, learners explore the chemistry that helps scientists learn about the environment and how they can help save it. Learners will determine if pollutants...

In this mechanical engineering activity, learners design shadow puppets with moving parts and use them to tell stories. Learners explore simple and complex linkages while constructing various...

In this activity related to microbes, learners create scale models of microorganisms and compare relative sizes of common bacteria, viruses, fungi and protozoa using metric measures: meters,...

In this art meets science activity, learners pack silver, ball-shaped ornaments in a single layer in a box to create an array of spherical reflectors. Learners can use this as a tool to study the...

In this drawing/mapping activity, learners design plots of land while incorporating positive strategies for improving water quality. Then, learners together examine how their plans would affect a...
