We all scream for ice cream! Individuals create home-made ice cream in the classroom. This is a delicious way to show a real-world application of the freezing point depression to your class.

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.

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.

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.

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...

Your plants will survive without you. Scholars create a device that can water plants using a coiled string. Along the way, they learn about adhesion and cohesion of water. The challenge is to keep the plants alive for at least a week.

Water, water, everywhere, but not a drop to drink—until we clean it, of course! Scholars design a filtration device that removes pollutants from water. The goal is to have the water come out as clean as possible from the device. How...

Orange you glad you can make circuits using fruit? Young electricians learn about electric circuits and electricity. As part of the lesson plan, they build a circuit with an orange and then with a banana.

Wheeeee! Young thrill seekers build a bungee jump—not for themselves, though, but for an egg. The egg must fall from a height of five feet and rebound within two inches of the ground or floor.

Paper is made from paper, right? Future scientists take bits of paper and produce sheets of recycled paper. The only drawback? It has to dry overnight.

If a ski lift had rockets, imagine how fast it would be! Scholars let their imaginations take flight as they build models for such a ski lift. Rather than using a rocket, though, they'll use a much safer balloon as the power source.

Homes come in many different shapes and sizes. Building a model of a geodesic dome is the ultimate goal for the activity. Cutting and folding is the way to go here.

Let's go fishing ... for paper clips! Individuals create a device that attracts paper clips. This device relies on an electromagnetism, where a flow of electricity in a loop of wire wrapped around a nail causes magnetism.

When is it okay to be suspended in school? When you're part of a human suspension bridge! Learners first model tension and compression in pairs. Once complete, they get together as a class to model a suspension bridge.

Sometimes, we all need somebody to lean on. Scholars create a human arch by leaning against each other. They consider different approaches to making the arch sturdier and stronger.

Shake your earthquake-resistant building prototype! Groups create structures using coffee stirrers and clay that can withstand seismic waves. They then test their structures against their own earthquakes.
