In this activity related to indoor air pollution, learners build take-home dust catchers with wax paper and petroleum jelly.

In this water activity, learners discover ways to move water across the water table.

This activity guide features three related explorations to help learners ages 3-6 investigate shadows via the following science concepts: A shadow is made when an object blocks the light; you can chan

In this ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.

In this activity, learners compare and contrast their own skin (including the area covered) with that of an orange.

In this water activity, learners build boats that float and sink. First, learners listen to the book, "Who Sank the Boat" and practice making predictions throughout the story.

In this activity, learners gain knowledge about how carbon moves through all four of the Earth’s major spheres (biosphere, hydrosphere, atmosphere, and lithosphere), and understand how humans influenc

In this physical sciences activity, learners explore how passive solar design increases energy efficiency.

In this water pollution activity, learners create pond water cultures and investigate the effects of adding chemicals or natural nutrients.

In this creative roleplay activity, learners will explore the various processes of the carbon cycle using movement and props to aid in comprehension.

In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.

In this water activity, learners explore how water drops behave on different surfaces.

In this activity about combustion and energy, learners observe a burning candle in a sealed jar and the burning of white sugar.

In this design challenge activity, learners make a balloon hover at eye level for five seconds, and then make it move by creating air currents.
