This is a demonstration you can use to show learners how valves and pumps work in concert to move blood through the circulatory system.

In this activity, learners investigate sound wave science, in stereo! Learners construct a "stereo" out of a metal coat hanger and piece of string to explore sound vibrations.

This is a virtual representation of a sound mixer containing pre-looped sounds of animal, insect, and environmental noises.

Discover how sound travels and what materials make better sound conductors. Can you hear better with your fingers in your ears? Find out with a coat hanger and some string!

In this activity, learners will explore the foods that are in their kitchen and what sugars are inside of them. Explore nutrition and food labels to better understand the foods you eat.

Do you have a hard time matching paint swatches with your furniture? When you consider human perception, color is context dependent.

In this chemistry activity (page 5 of the PDF), learners will see that chewing is more than just the crushing up of food; there is actually a chemical change going on at the same time.

In this activity, learners will explore engineering to construct an insect collecting tool (insect aspirator). The pooter uses suction to safely collect smaller insects that nets miss or may injure.

In this activity, learners will experiment with the physics of forces - kinetic energy and friction while making a moving toy woodpecker.

In this activity, learners will learn about proprioception, or the body's sense of its place and position in space.

In this activity, young learners (2 years and up) explore dirt and what is in it by painting with mud.

In this activity, learners will explore the physics of air by making a snake kite.

In this activity, learners will construct a measuring device (snake "string") to improve their observation skills.

In this activity, learners conduct an experiment to test how fast they can react. Learners try to catch a piece of paper with a ruler printed on it (or a ruler) as quickly as they can.

In this activity (14th activity on the page) about the sense of touch, learners examine if it is easier or harder to identify an object if they move their hands over it.

“Exploring the Universe: Imagining Life” is a hands-on activity in which visitors imagine and draw an extreme environment beyond Earth, then invent a living thing that could thrive in it.

In this activity, learners will experiment with the physics of flight by making a gliding contraption with strange looking wings. The activity explores flight with connections to the natural world.

In this activity, young learners (2 years and up) explore tree structure and biology. Tree products are explored by painitng with fruit.

In this activity (2nd activity on the page), learners explore how the nose is responsible for part of the flavor we taste in food.

Create an instrument that you don't play--you just listen to it through tubes of various lengths.
