In this activity, learners use information gathered from a variety of sources to design and make their own insect.

In this activity, learners build bridges and cantilevers in a series of "building out" challenges with straws and pins.

In this activity, learners make or use pre-made clay beams to scale and proportion. Specifically, they discover that when you scale up proportionally (i.e.

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.

Learners design, build, and test models of "dragon boats" made from up to three milk cartons.

In this activity, leaners explore building techniques by recreating the story of The Three Little Pigs.

In this activity, learners participate in several full-body interactive games to model the process of self-assembly in nature and nanotechnology.

Learners will construct a model of a heart valve using a film canister, a piece of masking tape, and a piece of paper.

In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.

In this activity, learners investigate what happens when you build up static electricity on plastic balls.

In this activity, learners recreate the lunar phases using the frosting from Oreo® cookies and place the phases in order. Round cream cheese crackers can also be used if cookies are not an option.

In this experiment, learners design and build a model room in a shoebox and furnish it with tiny furniture.

In this activity, learners explore a bucket of sand and beach objects.
