This great "re-use it" activity will demonstrate how to transform a greeting card into a box. Once constructed, the box can have many uses like holding special notes or keepsakes.

In this activity, learners will conduct an open-ended survey, and then organize and analyze results. What languages does everyone speak? What’s the most common? the least common?

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.

This activity (on page 2) explores how sensing is part of robotics. Learners try tying their shoes with different constraints.

Oboes's unique sound originates from the two small reeds a musician blows into. Make your own double reed instrument out of straw!

In this math activity, learners estimate how many pennies are in a jar by predicting and counting handfuls of pennies.

In this simple exploratory activity (1st activity on the page), blindfolded learners try to identify mystery items by smell.

Find out what it would be like to have ears shaped differently from your own! Design and make different animal ears then try them out.

In this physics activity, challenge learners to make and race a balloon-powered car. Learners construct the body out of a paper cup, wheels out of wooden spools. and fuel tank out of a balloon.

In this activity, learners use Starburst® candy to sort, classify, compare, and graph. Learners grab a handful of one-inch candy squares, sort them by color, graph the candy, and discuss the results.

In this activity, challenge learners to make a pencil stand on its tip using only two pieces of wire and two clothespins. Use this activity to demonstrate the center of gravity.

This quick demonstration (on page 11 of PDF) allows learners to understand why scientists think water ice could remain frozen in always-dark craters at the poles of the Moon.

In this activity/demo, learners investigate biobarcodes, a nanomedical technology that allows for massively parallel testing that can assist with disease diagnosis.

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.

Wheels aren't the only things that can "roll" objects that are placed on top of it. Make non-intuitive shapes from cutouts and a compass to demonstrate this.

This is an activity about robotics programming. Learners will discover how precise programmers have to be as they instruct a friend to make a peanut butter and jelly sandwich.

In this math game, learners solve a mind-twisting puzzle using dominoes. Use this activity to help learners practice counting, adding, and solving problems.

This math challenge, played with two players or a whole group, engages your problem solving skills.

In this activity, learners take a turn contributing a closed figure made of six squares to a large grid; each must be different from all the others on the grid so far.
