In this three part activity, learners explore and experiment with shadows to learn about the Sun's relative motion in the sky.

Create a painting by blowing air out of a straw. Push liquid acrylic paint around on some watercolor paper by aiming short bursts of air onto the paint puddle.

This guide features three related ramp explorations in which learners investigate the following science concepts: when placed on a ramp, some objects roll, others slide, and others stay put; the shape

In this "Sid the Science Kid" activity from Episode 109: The Perfect Pancake, learners make applesauce to explore irreversible change.

In this neuroscience activity (5th activity on the page), learners explore their sense of touch without using their senses of vision and hearing.

Are fingers the only place on the body where we use our sense of touch? In this activity (6th activity on the page), learners test the touch sensitivity of different parts of the body.

In this easy demonstration (3rd on the page), learners explore depth perception by conducting a test with two pencils.

In this activity, learners construct a home-made journal with simple, everyday materials.

In this activity, learners explore color, light and shadow by creating their own puppets to hold in front of a light source.

In this activity, learners track their movements with jumping and leaping graphs.

This fun hands-on astronomy activity uses a variety of simple props to help learners understand why they see what they see in a telescope.

In this activity, learners use various dress-up or costume pieces to play a game of change.

In this activity, learners explore a scale by comparing objects, which look similar but have different weights. Learners predict and then measure the weights of various objects using a scale.

In this engineering activity, young learners investigate multi-level buildings.

Choose a recipe to double (or triple, quadruple, or halve). Show everyone the recipe and engage them in figuring out: How much will we need to increase the recipe to feed everyone?

In this activity, learners observe, explore and investigate vibrating instruments in everyday places and create music in unique ways.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.
