Hello, and welcom to Density 1.0. This game alows you to experiment with 4 different shapes and measure their mass, volume and density (Mass divided by Volume = Density). FEATURES Bring a shape to the scale to read it's Mass. Bring a shape to the graduated cylinder (tube like figure with water) to read it's volume. Bring a shape to the tank to read it's density and see if it sinks or floats. Remember, the Density of water is 1.0 g/cc. Any density lower than 1.0 g/cc floats. Any density higher than 1.0 g/cc sinks. Demsity 2.0 will come out soon with more shapes and better graphics! NOTES: I got this idea from a site that allows you to do this with many different shapes. I learned about it in Science Class this year. (I do not know the site, sorry)
