PRODUCT DESCRIPTION

The objective of this lab is to see how much salt it takes to make a piece of potato float in a beaker of water. Students will learn that the higher the salinity, the easier things can float. Included in this download is the lab worksheet and a SMART notebook presentation that goes along with the lab. Materials needed for lab: beakers, water, salt, potatoes, measuring spoons.

If you want students to calculate the density of the fresh water and salt water, check out my High School Version
