This lab allows students to get a hands on experience with buoyancy. Students design and create a boat made out of aluminum foil and add "cargo" to it until it sinks. I challenge my students to see which group's boat can hold the most.
Included in your purchase is the lab directions, a key, and what I hope is helpful information for you so you can do this lab without a problem. I've also included different modifications in case you need it. Keep in mind this is a Word doc so you can easily edit it to your class and style.
