| Note to Teacher: Dinesh depicts air pressure using dots. She does not indicate that the dots are in motion. Her model suggests that she understands that reducing the volume in the syringe results in compacting the molecules that make up the air (however, she has drawn them to resemble a liquid more than a gas) and that the air pressure will increase. Her transfer example, in number 5, recognizes the relationship between volume and area (even though it is a pressure example instead of an air pressure example.) |
