What do you think? (answer on in your Interactive Notebook) 1.Which has more mass: a box filled with air or a box filled with water? 2.Which has more mass: a box filled with warm air or a box filled with cold air? Continued…

3. Draw what you think the molecules of air in the box of warm air and the box of cold air would look like if they were big enough to see. (I’m interested in how the molecules might look different at two different temperatures.) Continued… Warm AirCold Air

4.Why does wood float in water while a rock sinks? 5.How do you get a heavy boat to float? …end of “What do you think?” questions Image from
