In this activity, learners conduct a simple test to find their blind spot.

In this quick activity (page 1 of the PDF under SciGirls Activity: Extreme Sounds) about sound vibrations, learners will investigate which small objects, such as coins, hex nuts, or marbles, produce t

In this activity, learners discover that they can modify a regular piece of paper so that it's large enough for them to walk through!

In this math lesson, learners explore polynomial and rational function patterns.

In this game, learners build up six stacks of cards in the middle of the table, face up, in order from 1 at the bottom to 20 on the top. The first player to get rid of all his cards is the winner.

In this activity (18th on the page), learners conduct an experiment to examine memory.

To learn how friction affects motion, learners build a measurement tool from a rubber band and other simple materials.

In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

In this activity, learners use their understanding of probability to guess which color will be drawn from a bag.

Learners explore the concepts of equilibrium and center of mass by seeing how non-symmetrical objects balance.

In this activity, challenge learners to float a paper clip in a cup of water. Learners discover that a paper clip will sink in a cup of water, except when it is placed on a piece of paper towel.

In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.

In this hands-on botany activity, learners sprout vegetables in film canisters.

In this activity, learners experiment with shadows and light sources to understand the relationship between the angle illumination and the shadow's length.

In this math activity, learners use non-standard measurement (paces) to find the distance from one point to another. Learners practice estimating and measuring distances .

In this activity (on page 134 of the PDF), learners explore reaction time.

In this activity, learners make some music by constructing a kazoo out of a simple plastic drinking straw. Use this activity to explore sound, vibrations, and music.

Millions of organisms can live in and around a body of water.

This is an activity about lung capacity. Learners will measure their own lung capacity using a homemade spirometer.
