Learners follow a three-step process to start their own rock collection.

In this simulation, learners use M&M™ candy to explore radioactive isotope decay.

In this activity, learners explore dinosaur skeletons, anatomy, and locomotion. Learners compare and contrast dinosaur skeletons and drawings.

In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

In this activity, learners turn empty 2-liter bottles into a see-through compost container.

In this activity, learners explore different types of fossils by making their out of dough and objects from around the house.

Ancient trash tells archaeologists a lot about the past. In this activity, learners take a close look inside their trash can and think about the clues it offers about their lives.

This activity encourages learners to focus on the natural environment of the Eastern Woodlands before the arrival of European settlers.

This is a culminating activity which allows learners to summarize what they know about Woodlands Native Americans by creating illustrations and map symbols for a large outline map (see related Activit

In this activity about dinosaurs and survival, learners use scrap materials to create a miniature dinosaur habitat that includes a food source, water source, and shelter.

In this activity (on pages 12-15), learners make a crater model and test the effects of weather (rain) on its surface.

In this activity about dinosaurs, learners first participate in a group discussion about where and when dinosaurs lived, how big they were, and who studies them and how.

This activity (on pages 23-27) lets learners simulate the work of scientists who take core samples of Earth's rocky layers to determine geological history.

This is an activity about dinosaurs, fossils, and the work of paleontologists. Learners use hand tools (paint brushes, scoops, and sifters) to unearth fossil specimens in tubs of birdseed.

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

In this activity, learners will pretend to be archaeologist using this chilling experience.

In this activity, learners explore why animals, specifically dinosaurs, live in families.

In this activity, learners model hot spot island formation, orientation and progression with condiments.

In this archaeology-related activity, learners build their own time capsule and choose a storage location and a date to reopen it.

In this activity, learners work in groups to create a time line representing significant moments in their lives.
