In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.

In this activity about problem-solving, learners build a house for the Three Little Pigs using twenty straws and two index cards.

In this physics activity (page 6 of the PDF), learners will explore how static electricity affects surrounding objects.

In this activity, learners use a simple 3D model to discover why the Moon has phases.

In this activity, learners make a model of a power plant that uses steam. Learners use simple materials like foil, a tin can, and a pot of water to model a geothermal power plant.

This is an activity (located on page 4 of the PDF under What's Nano? Activity) about size and scale.

In this activity, learners will test soil content using their sample, some water and a container that seals.

In this activity, learners create a toy that demonstrates the First Law of Thermodynamics or the Law of Conservation of Energy.

This activity/demo introduces learners to aerogel, a glass nanofoam. Learners discover how aerogel is made and how well it insulates as well as learn about aerogel's other unique properties.

In this activity, learners will experiment with changing flower colors. Learners will investigate the effects of acids and bases on flower colors.

In this activity, learners will plan a snack within a budget. With a $20 limit (theoretical) to spend on snack for everyone, learners look over grocery store circulars and make their shopping lists.

This activity shows you how to make a mold terrarium using a jar and leftover food.

In this board game, learners explore the origins of meteors, meteoroids, and meteorites as well as the their characteristics and importance. They also discover some misconceptions about meteors.

In this activity, learners will be able to measure themselves in nanometers. A nanometer is a billionth of a meter, a unit of measurement used in nanotechnology.

In this activity, learners craft their own model of a comet on a stick to make it fly around the room.

In this activity, learners model erosion using a clear shoebox and sand or soil.

In this activity, learners add objects and substances to carbonated water to discover that added objects increase the rate at which dissolved gas comes out of solution.

In this activity, learners will observe laminar and turbulent flow of water using only a plastic bottle, liquid hand soap, food coloring and water.

Learners work together as a group to learn a new physical activity. After working for a few rotations, learners time themselves as part of a contest.

In this activity, learners conduct an experiment to explore how water flows up from a tree's roots to its leafy crown.
