In this outdoor activity/field trip, learners catch and observe water striders to explore their movement and feeding behaviors.

In this chemistry investigation, learners combine common cooking substances (flour, baking powder, sugar, salt, pepper, oil, water, food coloring) to explore mixtures.

In this activity, learners play with surprising sand that doesn’t get wet! Learners explore how water behaves differently when it comes in contact with "magic sand" and regular sand.

In this outdoor activity/field trip, learners locate and study plants and animals in several freshwater pond habitats.

In this chemistry challenge, learners discover that many chemical reactions involve heat loss or gain.

In this demonstration, learners observe how liquid nitrogen both boils and freezes ingredients to make ice cream in two minutes.

In this outdoor, freshwater activity, learners explore the behavior and food preferences of crawdads (or crabs) by "fishing" for them with various baits.

In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.

In this hands-on science experiment, students combine their understanding of the different states of matter and the characteristics of various chemical reactions.

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.

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