Learners experiment with a commercially available liquid-crystal coaster. They warm the material with their hands for varying lengths of time and observe the changing colors that result.

In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.

In this activity (on pages 6-11), learners work as a team to investigate how impact craters on Earth, the Moon or other planets take shape and what patterns they make.

In this optics/mathematics activity, learners use two hinged mirrors to create a kaleidoscope that shows multiple images of an object.

In this activity, learners explore the different heating properties of soil and water.

In this activity (on pages 26-33), learners play parasitologists, solving several "mysteries" about people who got sick from various parasites. In teams of four, each member solves one mystery.

In this activity (on page 8), learners model how marble statues and buildings are affected by acid rain.

In this activity about computer programming, learners follow instructions in a variety of ways in order to successfully draw figures.

In this activity, learners use simple materials and basic tools to construct a special toy to explore pendulums. As the head of the toy bobs one way, the eyeballs bob the other way.

In this activity, learners map their world by drawing a plan of their bedroom.

In this activity about afterimages, learners explore what happens when receptor cells called cones in your eye's retina get tired.

Combine math and exercise with this activity. Learners count how many times in a row they can skip rope or throw and catch a ball.

In this activity (page 1 of the PDF under SciGirls Activity: Double Dutch), learners will stand twelve feet apart swinging a rope at the slowest tempo possible while someone uses a stopwatch to record

In this activity (posted on March 14, 2011), learners follow the steps to construct a camera projector to explore lenses and refraction.

In this activity, learners make their own heat waves in an aquarium.

The Chinese invented paper made from plants and cloth about 2,000 years ago. Learners follow a similar process to make paper from recycled paper.

In this activity, learners explore physics by building a catapult that launches marshmallows with household objects.

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 outdoor activity, learners make models of homes that might protect small animals from the elements, then search living plants for real structures made by small animals.

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