In this activity, learners build a machine made of craft sticks to multiply the levering motion of their hands and create a device that bends and extends.

In this family or group inquiry activity, learners use their senses to explore a local forest or woodland.

In this engineering design challenge, learners animate a facial expression and make a machine (zoetrope) that plays the animation back.

In this activity, learners build a sled kite that models a type of airfoil called a parawing.

In this activity, learners explore how salt water freezes in comparison to fresh water.

In this activity, learners discover if carbon dioxide has an effect on temperature.

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 engineering design challenge, learners make a bubble maze that allows bubbles to move through a series of “on” and “off” switches.

In this engineering design challenge, learners build an octopus-inspired suction pad that can grab an object and hold it tightly in the air.

In this activity, learners build a figure that moves and "comes to life" when they pull its string.

In this engineering design challenge, learners build an air-powered spinning machine.

Learners create their own piece of history by decorating, shattering, and piecing together a flowerpot "artifact".

In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.

In this activity, learners conduct an experiment to explore how water flows up from a tree's roots to its leafy crown.

Build your own version of a favorite carnival game, in which a marble races down a maze consisting of rows of nails.

In this activity, learners design miniature cars. Learners can create a telephone car, soccer car, merry-go-round car, or any other theme car they can imagine.

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.

In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.
