In this fun activity about spiders, learners build and design a spider from cardstock, straw, string, and pipe cleaners.

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.

This event guide features three related explorations in which learners investigate the following science concepts: how you design and build a structure helps determine how strong it will be; different

In this engineering activity (page 5 of PDF), young learners investigate how materials and design contribute to the strength of a structure, particularly walls.

In this activity learners will build structures out of blocks and then roll balls to try to knock them down.

A design challenge that takes paper airplanes into an entirely different direction: a magnus glider uses cups and and rubber bands to create a glider that uses the same forces that a curveball (from b

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

In this activity, learners construct a simple air pressure launcher for paper rockets.

In this activity learners will build roller coasters and test them using small balls or marbles.

In this activity, learners design and build a Zoom-a-rang using everyday materials. Experiment with different materials and Zoom-a-rang designs to see how they fly.

In this activity, learners use simple, everyday materials to experiment with balls and ramps.

In this inquiry-based learning activity, learners design, build, and test their own ramps. They are introduced to a variety of materials and explore putting them together.

In this activity, learners explore different ways to stack cups to meet a personal goal.

In this activity, early learners combine pre-cut recognizable shapes and their own abstract ideas to make representational pictures (e.g. houses, trees, shoes).

In this activity, learners consider how a simple machine, a lever, turns a small push or pull (a small force) into a larger--or stronger--push or pull (a larger force).

In this activity, learners design and build their own parachute using household materials with the goal of landing their passenger safely on a target.

In this activity, learners make a parachute out of tissue paper, tape, and string. Then, learners test their parachute to see how many paper clips it can carry.
