In this engineering challenge, learners design and build a crane out of cardboard to see how heavy a load it can lift.

Learners observe projectile motion by launching wooden balls off of a table top. They set up a rubber-band launcher so that each ball experiences a consistent amount of force.

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

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 demonstration, learners observe as a bottle is placed on a table with wooden hoop balanced on top and a pencil balanced on top of the hoop.

In this activity related to magnetism and electricity, learners discover that a magnet falls more slowly through a metallic tube than it does through a nonmetallic tube.

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

Learners build simple catapults and use them to launch cotton balls.

Learners work in pairs to create three simple types of bridges, a beam bridge, an arch bridge, and a suspension bridge.

Learners investigate weight by building a spring scale. They observe and record how it responds to objects with different masses.

In this activity, learners construct speedy vehicles made out of paper plates and powered by twisted rubber bands.

In this activity, learners build an old-fashioned paddle boat out of simple materials.

Learners drop two different masses of play dough and observe how long it takes them to hit the ground.

Learners build a pendulum from a yo-yo, and then design their own experiment to determine what affects the pendulum's period of swing.

In this hands-on activity, learners use an assortment of (mainly household) items to complete Rube Goldberg-type challenges.

In this activity, learners build a model roller coaster to help the Mummy entertain the Atom's Family monsters. Learners assemble the roller coaster between two chairs using vinyl ceiling molding.

In this activity, learners build a seesaw powered by magnets.

In this activity, learners build mini catapults using paint paddles and a spoon. Use this activity to introduce learners to forces and projectile motion.

This fun video explains how to make a batch of oobleck (or slime) and why this special substance is known as a "non-Newtonian" fluid. Watch as Mr.

With a magnet, iron fillings, and a bottle, you can create a cool demonstration about magnetic lines of force: the fillings will arrange themselves within the magnet's magnetic field.
