In this lab students can see the basic principles of density and buoyancy as raisins rise and fall in a beaker. This lesson includes a student lab worksheet and an 8 page SMART notebook presentation or Powerpoint (your preference) that walks students through the lab, has links to videos, and closure questions at the end. Materials needed: beaker, raisins, and clear soda such as 7 up or ginger ale. The same result would happen if you used water, baking soda, and vinegar instead of soda.
