In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

In this activity, learners make different shapes that hold exactly one mole of gas (air).

In this activity, learners compare the ways of life of Plains Native Americans who hunted and moved frequently to follow the buffalo herds, and Native Americans who farmed and lived in more permanent

This PDF contains 12 calendars (12 months). Each month contains activities about math. Things to do on familiar holidays (like July 4), less common holidays (like Backward Day), and any day.

In this activity, learners explore how the shapes, sizes, and distances of land masses appear differently on two different models of Earth: an icosahedron and a flat map.

In this activity, learners explore Charles' Law in a syringe.

Using simple, inexpensive items, learners build and test submarine models.

In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.

This activity offers learners and their families several ways to raise their awareness together about home water.

In this activity, learners explore dinosaur fossils and skeletons. First, learners listen to "Tyrannosaurus Rex" by Daniel Cohen to learn about T. rex dinosaurs specifically.

This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection by encouraging them to formulate questions that can be answered through scientific investi

Get all wrapped up in a lesson about skin!

In this activity, learners create a model using metric measuring tapes and atmosphere composition data.

In this activity, learners are introduced to tree rings by examining a cross section of a tree, also known as a “tree cookie.” They discover how tree age can be determined by studying the rings and ho

In this activity, learners investigate passive solar building design with a focus solely on heating.

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

In this weather forecasting activity, learners determine the location of cold and warm fronts on weather plot maps.

In this very hands-on lesson, learners will investigate dendrochronology (the study of tree rings to answer ecological questions about the recent past) and come up with conclusions as to what possible

This is a classic exercise for visualizing the scale of the Solar System.

In this activity, learners create their own weather forecast map.
