In this activity, learners complete a series of drawing activities to explore scale and powers of 10. Learners first trace each other on 1-meter-square pieces of paper.

This simple construction activity teaches the importance of architectural structure. Learners build and test designs for a paper "doghouse" strong enough to hold the weight of a jumbo dog biscuit.

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

In this indoor and/or outdoor activity, learners make an anemometer (an instrument to measure wind speed) out of a protractor, a ping pong ball and a length of thread or fishing line.

In this pencil and paper activity, learners work in pairs and simulate how astronomical spacecraft and computers create images of objects in space.

In this activity, learners help a poor cartographer color in the countries on a map, making sure each country is colored a different color than any of its neighbors.

Computers store drawings, photographs, and other pictures using only numbers. Through this activity, learners decode numbers to create pictures using the same process that computers use.

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

In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

In this activity, learners build bridges using paper and explore how much weight each bridge design can support.

In this computer science activity about finite-state automaton (on page 45 of the PDF), learners use a map and choose various pathways to find Treasure Island.

In this activity, learners will build thier own balance scale. Learners will explore weight and comparison through this activity.

In this inquiry-based activity, learners investigate the basic forces of flight as they construct their own paper glider that represents a rainforest creature from Borneo (large, tropical island in So

In this activity, learners play a card game that explores the relative sizes of various objects. Learners compete to organize their hand of cards into lists of objects from largest to smallest.

Learners make their own simple slide rules out of paper and learn how they work.

In this activity, learners play a card game that explores different size scales--macro, micro and nano.

In this activity, learners investigate the movement caused by dispersion. Learners discover that dispersion is the random movement of objects.

Build a house you can fit inside, using cardboard tubes.

In this fun sticker activity, learners will create a size wheel with images of objects of different size, from macroscopic scale (like an ant) to nanoscale (like DNA).
