In this collection of demonstrations, learners explore Newton's Laws of Motion.

In this activity, learners explore what happens when polarized white light passes through a sugar solution.

In this activity, learners explore the engineering design process (EDP)—the process engineers use to solve design challenges.

In this activity/demo, learners discover how liquid nitrogen cools a creamy mixture at such a rapid rate that it precipitates super fine grained (nano) ice cream.

In this activity, learners conduct tests for proteins, glucose, and starch.

Just like birds, some dinosaurs had air-filled (pneumatic) bones, which made the dinosaurs' skeletons lighter.

This is a classic exercise for visualizing the scale of the Solar System.

DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique. This activity allows you to see long, stringy strands of DNA extracted from wheat germ.

In this activity, learners count and measure kidney beans to explore natural selection and variation. Learners measure the length of 50-100 beans.

This is an activity about friction as well as kinetic and potential energy.

In this chemistry activity, learners will separate a mixture of FD&C dyes (colors certified and allowed by the US for the Food, Pharmaceutical, Cosmetics & Personal Care industry) to practice

In this activity, learners of all ages can become food scientists by experimenting with flour and water to make basic pasta.

In this yummy earth science activity (page 5 of the PDF), learners use fudge to learn about different kinds of lava.

Some animals can swallow food whole, but humans have to chew. In this activity, learners will investigate what saliva does chemically to food before we even swallow.

This activity was designed for blind learners, but all types of learners can use it to investigate heterogeneous and homogeneous mixtures and solutions, identify the differences, and explore the conce

In this kinesthetic activity, learners move pom-pom "ions" across a membrane to simulate how an action potential is propagated along an axon.

In this activity, learners will discover why there are holes in bread.

In this activity, learners investigate vitamin C.

In this demonstration, adult learners create a lava lamp using beer and nuts! Use this pub-themed activity to demonstrate the effects of buoyancy and bubbles.

In this chemistry activity, learners prepare two petri dishes, one filled with water and one filled with milk.
