This resource is a set of three web-based labs for grades 7-9 relating volume, temperature, and pressure of a contained gas. Lab 1 investigates the effect of volume changes on the pressure of a confined gas at constant temperature. Lab 2 explores the effect of temperature changes on a confined gas held at constant volume. Lab 3 investigates the relationship between volume and temperature. Detailed lesson plans with objectives and assessment ideas are included.
This item is part of a larger collection of interactive Java labs developed for use in middle school and high school. See Related items on this page for a link to the full collection.
6-8: 4D/M3ab. Atoms and molecules are perpetually in motion. Increased temperature means greater average energy of motion, so most substances expand when heated.
6-8: 4D/M3cd. In solids, the atoms or molecules are closely locked in position and can only vibrate. In liquids, they have higher energy, are more loosely connected, and can slide past one another; some molecules may get enough energy to escape into a gas. In gases, the atoms or molecules have still more energy and are free of one another except during occasional collisions.
6-8: 4D/M8. Most substances can exist as a solid, liquid, or gas depending on temperature.
11. Common Themes
6-8: 11B/M4. Simulations are often useful in modeling events and processes.
