In this environmental health activity, learners investigate their breathing and pulse rates, and learn how these measurements are affected by physical activity.

In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

In this activity, learners explore geometry and spatial relationships as they figure out how to arrange tables for a party.

In this activity, learners build bridges using paper and explore how much weight each bridge design can support.

In this activity, learners explore fractions as they help gators share pies.

In this simple activity, learners discover how a mere piece of paper can be used to hold up the weight of a heavy book.

In this activity, learners follow clues to find five puzzle pieces, then assemble them. This activity works well with a whole group, individuals, or families.

In this math activity, learners explore probability as they play a game. Learners will categorize everyday events as either impossible, possible or certain.

In this math lesson, learners play two different games to help them understand coordinates. First, learners read the book, "The Fly on the Ceiling," by Julie Glass.

In this activity, learners construct a playable kazoo from inexpensive materials. They will experience how vibration creates sound waves and music.
