Source Institutions
After a discussion about what a parachute is and how it works, learners create parachutes using different materials that they think will work best.

Magnet Tower
Source Institutions
In this activity, learners build magnetic towers to explore the forces and properties of magnets.

Water Tower Challenge
Source Institutions
In this activity, learners explore how engineers work to solve the challenges of a society, such as delivering safe drinking water.

Throw Your Weight Around
Source Institutions
During this activity, learners take part in a variety of tasks which involve moving and balancing different body parts.

Tissue Paper Parachute
Source Institutions
In this activity, learners make a parachute out of tissue paper, tape, and string. Then, learners test their parachute to see how many paper clips it can carry.

Extreme Kicking Machine
Source Institutions
In this design challenge activity follow up to "Kicking Machine", learners add a hands-free feature to their Kicking Machine.

Center of Gravity
Source Institutions
A simple, yet fun activity that lets learners find the center of balance of a ruler (or any long thin object). Developed by the Exploratorium and no assembly needed.

Crazy About Kites
Source Institutions
In this activity, learners build a kite out of paper, change it, and try to make it fly even better. With their new knowledge of kite making, students can then go on to create their own kite designs.

Flinker
Source Institutions
In this activity, learners make a foam packing peanut "flink"--neither float away nor sink--in water. Learners experiment with materials to make a Flinker that "flinks" for 10 seconds.

Kicking Machine
Source Institutions
In this design challenge activity, learners build a machine that kicks a Ping-Pong ball into a cup lying on its side 12 inches away.
