Learners explore three-dimensional geometric frames including cubes and tetrahedrons, as they create bubble wands with pipe cleaners and drinking straws.

In this activity, learners predict where a ball will go after it bounces off another object. Learners discover that the motion of objects is predictable based on laws of motion.

Working in teams of four, learners build tetrahedral kites following specific instructions and using specific materials.

In this activity, learners create a mind and math puzzle that requires a three-dimensional solution.

Groups of learners are provided with a generic car base and an egg. Their mission: design a device/enclosure to protect the egg on or in the car as it rolls down a ramp with increasing slopes.

In this design challenge activity, learners use a balloon and other simple materials to design an air-powered rocket that can hit a distant target.

In this activity, learners determine the shape of an unseen object by bouncing a ball off the object.

In this three/four-day lesson, learners calculate perimeters and areas and draw the castle plan to scale.

In this activity, caregivers and young learners work together to craft and talk about shapes and relative positions of such shapes by creating a mobile.

The goal of this activity is to design, build and test a house or toy for an animal.

In this engineering activity, learners explore simple machines and then build cardboard automata using cams.

In this activity, learners build mini-basketball courts and explore the laws of physics. Learners discover that everything you throw or shoot on earth travels in a parabola.

In this activity, learners construct a device that allows them to view 2-D images in 3-D.

In this activity, learners build inexpensive kaleidoscopes using transparency paper and foil (instead of mirrors).

Learners explore magnetism and motion as they build a simple marble run. Learners test different arrangements of plastic and cardboard tubes, bottles, and cups on a magnetic board.

In this activity (on page 2 of the PDF under GPS: Luge Activity), learners will construct a model hovercraft out of an empty spool and a piece of cardboard.

This activity (on page 2 of the PDF under SciGirls Activity: Kites) is a full inquiry investigation into how a kite’s shape affects its performance.

In this activity, learners create a model of a hot air balloon using tissue paper and a hairdryer. Educators can use this activity to introduce learners to density and its role in why things float.

Create airplanes from straws and geometric shapes. Test them out to see how far they can fly, or how accurately they can be aimed.

In this activity, learners will create an optical illusion top. Learners will explore color mixing, physics and design through this activity.
