In this simple and fun activity, learners discover the relationship between vibration and sound by making a squeaky toy instrument out of simple household materials.

In this game, students will become familiar with fish shapes, learn that fish within a given taxonomic family have similar body shapes, and discuss how different body shapes enable fish to survive in

In this activity, learners use a chemical reaction to visualize where moisture forms on the body.

In this activity, learners investigate the reflective properties of light and mirrors as they make a kaleidoscope.

Design and create an optical illusion toy that makes two pictures appear to become one. This is called a thaumatrope and will allow the learner to investigate the phenomenon of persistence of vision.

Over 1 or 2 days, learners use vinegar to remove the calcium from a chicken bone. They then explore how the bones have changed. An accompanying video with Mr.

In this activity (26th on the page), learners construct an easy-to-build device and test motor learning.

In this activity, learners use gumdrops and toothpicks to model the composition and molecular structure of three greenhouse gases: carbon dioxide (CO2), water vapor (H2O) and methane (CH4).

This activity generates learner excitement about light through the creation of a room-sized rainbow.

In this simulation activity, learners act as parts of the circulatory system and discover how it serves as a transport system for food/nutrients, oxygen, carbon dioxide and waste.

In this activity, learners explore the gait of horses by constructing flipbooks with British photographer Eadweard Muybridge's famous photographs.

In this activity, learners explore and experiment how we can use our bodies everyday to get from one place to another.

In this activity, learners make three different "seed" types and determine which design flies the farthest.

In this activity, learners discover that our hands are not reliable thermometers.

In this activity, learners discover how artists start with a skeleton and turn it into a realistic drawing of a dinosaur.

In this activity, learners examine the properties of different seaweeds, investigate what happens when powdered seaweed (alginate) is added to water, and learn about food products made with seaweed.

Most people break at least two bones in their lifetime. In this activity, learners will use celery stalks to model the many ways that bones can fracture.

In this activity, learners construct a cereal chain as a model of how proteins are made in the cell.
