Using simple materials, learners will construct the end effector (grasping device) of a robotic arm and use the device to capture and pick up an object.

In this activity, learners take on the role of various parts of the cell in order to model the process of protein synthesis.

Learners explore the variables that affect the properties of ice and the places where different types of ice are found.

This is an online simulation of how sound changes due to environment. How does place--like a cave, a pier, or a forest--affect certain sounds?

In this experiment, learners use a blow dryer and water bottle to observe and record changes in air pressure caused by changes in temperature.

In this activity, learners simulate the behavior of the atmosphere.

In this activity, learners explore how wind tunnels provide feedback to engineers about the performance and durability of products such as planes, cars, and buildings.

This game plays a dozen different sounds, altered to simulate what they would sound like if you had hearing loss.

In this activity, learners simulate Otto von Guericke's famous Magdeburg Hemispheres experiment.

In this activity, learners will use cereal to conduct an experiment and investigate how decreased bone density is related to increased risk of bone fracture.

Experiment with friction and make bearings for a whirligig! This activity is a nice introduction to friction and bearings and demonstrates why bearings are useful for spinning.

In this activity (page 12), learners apply the concepts of pixilation and pointillism to the world of biomedical science.

In this activity, learners explore the engineering behind the conveyor belt and consider the impact this invention has had on transportation and the coordinated shipping and delivery of goods.

This fun and simple hands-on astronomy activity lets learners imagine what would happen if our Sun were replaced with a black hole.

A group of learners simulates the spread of disease by trading slips of paper, one set of which has been treated with a baking soda solution.
