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 build a sled kite that models a type of airfoil called a parawing.

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 (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, 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 build a mini crank machine to make a bird "fly." This engineering activity introduces learners to automata, rotational motion, cranks and cams.

In this activity, learners will explore the water cycle by creating a small atmosphere.

In this engineering design challenge, learners make a bird and then control its flight with attached strings.

In this engineering/design/arts and crafts activity, learners design and build "platforms" or "bridges" that can hold weight, and test which glue makes the strongest structure.

This activity shows you how to make amazing crystal spikes using Epsom salt and the sun.

In this activity, learners build their own construction cranes using tongue depressors and pushpins.

In this activity on page 2 of the PDF, learners test different materials to find out which is the best insulator.

In this activity, learners build cars using syringes and water-powered hydraulics. Learners construct the car frame out of cardboard and set up a hydraulic system to raise and lower the car.

In this activity, learners follow simple historical maritime recipes to cook up hardtack and swanky, and then compare the foods they eat to what was served on ships in the past.
