Hover Challenge

Have you ever been inside a submarine and wondered how it could float in water, but not sink all the way to the bottom? Build your very own submarine with this Hover Challenge and discover the two forces that act upon a submarine called buoyancy and gravity! Now go and challenge your friends to see whose submarine is the most successful.

Wind Powered Pinwheel

If you've been outside anytime this week, you would've noticed the crazy weather we've been having. This is the perfect chance to learn about wind and to build your own wind powered pinwheel! Wind is a renewable resource, which means that it will never run out and can be used over and over again. Head outside and measure how strong the wind is by seeing how fast your pinwheel is spinning!

Leakyproof Bag

Have you ever seen a filled ziplock bag with holes, but doesn't leak?! Test out the Leakproof Bag Experiment and find out! Ziplock bags are made out of chains of molecules also known as polymers. The specific type of polymer for ziplock bags are known as polyethylene (LDPE). When the pencil pokes through, it only separates the chains of molecules, but does not completely break the chains of molecule, so the water does not leak!

Do Not Open Bottle

What would you do if you saw a bottle that says, "Do not open" just sitting on the kitchen table? Since April Fool's is coming up, test out the Do Not Open Bottle experiment to see how water molecules work together to seal water inside the water bottle!
