In this experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean.

In this physics activity (page 6 of the PDF), learners will build a class 1 lever and hypothesize and test the distances two objects need to be placed from the fulcrum in order to balance.

In this simple and fun activity, learners build a tower of cups to explore distribution of weight. Learners make predictions about their towers and test their designs.

In this activity, learners explore in what ways the shape of the land and the pull of gravity influence how water moves over Earth.

In this activity, learners will explore how computers represent pictures using pixels.

In this activity, learners construct a paper glider to experiment with aerodynamic forces.

In this activity, learners will see how UV light affects colors over time by making their own sunprint on construction paper.

In this optics activity, learners make a lens and explore how the eye manipulates the light that enters it.

Demonstrate the Bernoulli Principle using simple materials on a small or large scale.

In this activity (page 2 of PDF), learners play with a lens and a piece of paper to focus an image on the paper. Learners look at different things, and see how the lenses affect the image.

Using paper, paper clips, an index card, and tape, teams of learners design flying devices to (1) stay in the air as long as possible and (2) land as close as possible to a given target.

This activity demonstrates liquefaction, the process by which some soils lose their solidity during an earthquake.

In this graphing exercise (page 2 of the pdf), learners compare their own height to the length of various sharks.

This hands-on astronomy activity lets learners hunt for different objects in the night sky that contribute to stellar and planetary formation, using a Treasure List.

Whether it's the genetic code, an ancient language, or patterns of light in a distant galaxy, scientists often have to play the role of decoder.

By building a model of a lung and diaphragm, learners discover the function of various parts of the body's respiratory system.

In this math lesson, learners measure, predict and determine the frequency of an event as it relates to how close Whirlybirds land to a target.

This is a hands-on activity that uses bread and household materials to grow mold. Learners collect dust from a room, wipe it on food, and contain it. One to seven days later, mold has grown.

Why is ocean water sometimes the warmest when the average daily air temperature starts to drop? In this activity, learners explore the differing heat capacities of water and air using real data.

Learn about chemical reactions by making a Bubble Bomb, a plastic bag you can pop with the power of fizz.
