This lab is so much fun! If your students are learning about buoyancy (which can be perfectly tied into your density unit), this lab is the absolute best way to go! Students build three small boats (out of just one incredibly common material you have already), find the mass and volume of the boats, and then see how much mass can be added before the boat sinks! The instructions and feedback questions for this lab are very easy for students to understand, so your job is to just enjoy watching your students learn and have a blast! All you need are some plastic "tubs" (the small storage ones that are just big enough to allow students to add their "boats" into), a triple-beam balance, and something that acts as weights (I use large washers, but you can also use marbles - you will need quite a few as a well made boat can hold a surprisingly large amount of weights!). This lab is a Blast and my students LOVE it! (Hint: If you want, you can always shrink the size of the boats and students can complete the exact same lab with fewer weights.) Have Fun!
The designed PDF can be enjoyed the way it is, but a straightforward editable word doc is included as well.
