Computer Simulation We will now use the computers to practice with density using a computer simulation. Work with your partner on the simulation be sure to complete the density investigation worksheet on L/R. Density Simulation https://phet.colorado.edu/sims/density-and-buoyancy/density_en.html

What makes a block more likely to sink?

Density Which is Denser?

Watch: Density vs Temperature In your notebook copy this question How does Temperature affect the density of water and air? As you watch the video record your answer.

Draw a model showing Hot Air and Cold Air pg. 45R Be sure to describe and show Temperature Molecular movement Molecular spacing Amount of molecules (mass)

Which state of water is least dense? Most dense? liquid Solid Gas Molecules move very slowly! They are close together. Molecules move faster and are more spread apart. Molecules move very fast! They are very spread apart. Most Dense Least Dense

Warm Air Less Dense Molecules are further apart. Air is lighter. Density of warm and cold air. Cold Air more Dense Molecules are closer together. Air is heavier.
