Starters - Week #17
April 4 - How do you find the mass of a solid? of a liquid? How do you find the volume of solid? of a liquid?
April 5 - A pink liquid has a volume of 500 mL and a mass of 347 grams. A green liquid has a volume of 250 mL and a mass of 102 grams. Without using a calculator, tell me how they will layer? Show your work.
April 7 - List 3 possible scenarios where a marshmallow will increase in volume (they should all involve a change in temperature). What has happened to the particles in the marshmallow?
April 8 - Design an experiment that investigates the diffusion of particles.
