Exploring Energy: Energy Conversion
The energy is not really lost, it is just converted to a different form. Pupils learn about the conversion of energy in the fifth segment of an energy unit with six parts. Learners develop an understanding of the conservation of energy...

Making Moon Craters
Create an egg-citing study of energy. Pupils investigate the effect of height and mass on the overall amount of energy of a falling object. The fourth segment in a six-part series on energy uses a weighted egg falling from different...

Let's Make an Elastic Puppet
Create bending joints—but don't break! The activity shows how to make a puppet using straws and fishing line. Pupils create cuts to make joints that rely on the elasticity of the straw to bend and return to their original shapes.

Slime!!
Who's going to get slimed? Your entire class! Scholars create slime using Borax, water, and white glue. Some food coloring can give the slime a bit of color.
DiscoverE
Textbook Support Challenge
Textbooks are heavier than a sheet of paper, so how can paper hold up a textbook? Young engineers create a structure out of paper that can support a textbook. To add another wrinkle, they must stay within budget and time constraints.
DiscoverE
Product Dissection
Sometimes, taking things apart is more fun than putting things together. Groups of learners participate in a reverse engineering activity. They dissect a device of their choosing to see how it works—great hands-on learning from the...

Wind Farm
A wind turbine is essentially just a giant pinwheel, right? Individuals first create pinwheels from paper, pins, and pencils. In groups, they model a wind farm along a coast and then test out their designs using an electric fan.
DiscoverE
Paper Tower
Read all about it! Challenge your class to build taller and stronger. Newspapers provide the means to build towers in a simple activity. Scholars try to build as tall a tower as possible with just two sheets of newspaper.
DiscoverE
Pilot a Balloon
Balloons will go where you want them to. Young pilots first add paper clips to a balloon to make it neutrally buoyant. They then use cardboard to steer the balloon in different directions, taking air pressure into account.

Harmless Holder
Here's a lesson that's not for the birds! Scholars design and build packaging for soda cans that is environmentally friendly. These packages must be durable, easy to carry, and have no environmental impact.
DiscoverE
Siphon Pump
Defy the laws of gravity. A simple activity has learners create a siphon pump for water. The challenge is to get water to flow upwards through a tube.
DiscoverE
Tunnel Meetup
Meet me in the tunnels. Scholars choose a tunnel entrance and mark it on their side of the cardboard. They describe the location to their partners and see if they can guess each other's locations. Punching a hole through the cardboard...
