In this activity (located on page 6 of the PDF), learners explore the ways people access water in their homes.

In this activity, learners will predict the size of a giant scale model of a comb or other rectangular object, then make one. If you tripled the size of a dollar bill, could you sit on it?

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

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

In this two-part activity, learners explore the Earth and Sun's positions in relation to the constellations of the ecliptic with a small model.

In this activity, learners will explore what a constellation is and make their own.

In this activity, learners construct paper airplanes that twist and turn.

In this activity (last activity on the page), learners make a model of the eardrum (also called the "tympanic membrane") and see how sound travels through the air.

In this activity, learners explore density and buoyancy as they design and construct rafts.

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

In this activity, learners build bridges out of newspaper and tape to explore how structures are designed to bear loads.
