In this activity, learners create a traditional Mexican noisemaker (a matraca) using cardboard, craft sticks, and a wooden dowel.

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

In this activity, learners will make their own slushies and learn some of the science behind how the process works.

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.

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

Learners make their own paper using old newspaper. Learners can make their paper colorful by adding construction paper.

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.

In this activity (posted on March 27, 2011), learners follow the steps to construct a mini zoetrope, a device that produces an illusion of action from a rapid succession of static pictures.

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.

In this activity about living things and gravity (page 5 of PDF), learners design and build an exoskeleton or an endoskeleton for an animal of their own invention.

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