In this activity, learners explore how air warms when it condenses water vapor or makes clouds.

In this activity, learners mix milk, vinegar, baking soda, and water to create sticky glue. Use this activity to explain how engineers develop and evaluate new materials and products.

Can gelatin (like Jell-O ®) change the speed of light?

In this environmental activity (page 16 of the PDF), learners will calculate the amount of energy they save by recycling paper, plastic, glass, and aluminum materials over the span of a week.

In this activity, learners touch supercooled water drops with an ice crystal and trigger the water drops to freeze instantly.

In this optics activity, learners make a simple telescope using two lenses and a cardboard tube. Learners construct the telescope and then calculate its magnification.

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.

In this activity, learners will predict the size of a giant scale model of a comb or other rectangular object, then make one. If you tripled the size of a dollar bill, could you sit on it?

In this activity, learners explore how engineers work to solve the challenges of a society, such as efficient planting and harvesting.

In this experience, learners use the internet to research physical details about Chihuly's Fireworks of Glass "Tower" and "Ceiling" and consider the decisions Chihuly had to make as he was planning th

This laboratory exercise is designed to show learners how DNA can be extracted from a chunk of thymus (sweetbread) or liver.

In this exciting and tasty chemistry activity which requires adult supervision, learners explore how chemistry affects a simple everyday activity like cooking.

In this activity, learners use a straight line to learn about circles. Learners measure and record the diameter and circumference of different sized cylindrical objects on a chart.

This activity models the necessary balance of creating power and cleaning up its associated waste. Learners participate in a game where they attempt to move forward toward a goal.

Yes, you can weigh your car by figuring out your wheel's tire pressure combined with the "tire's footprint." You'll need someone with a car, driver's license, and safety in mind.

In this highly collaborative activity, learners design and complete a controlled experiment which attempts to answer a simple question about the slime mold Physarum.

In this activity, learners will train to increase bone strength and to improve heart and other muscle endurance by performing jump training with a rope, both while stationary and moving.

In this activity, learners explore how a flashlight works, showing the electric circuit and switch functions of this everyday household item.

In this activity, learners will examine various world data maps to combine the information and predict which areas could be tropical rainforests.

In this activity, learners listen to a story about a made-up endangered species--a flying frog! Learners print out six story pages and then draw the pictures and write the captions.
