This week we will look at density, buoyancy and displacement. To help us understand a little more about density and buoyancy I am going to refer to the expert....Bill Nye.
To win this competition you will have to hold the most weight before it sinks. We will be comparing how much weight your boat can hold in pennies (remember a roll of 50 pennies is 4.5 oz) and in golf balls (remember a golf ball weighs 1.62 oz).
This week we will begin to race our cars!!!
After we race our cars, we will be discussing our next projects.
