Requirements

On OS X 10.9 or newer, you will need to install a launcher application to run this Java activity. If you have not already installed it, please:

  • Download the launcher installer
  • Open the downloaded .dmg file and drag the CCLauncher application to your Applications folder
  • Return to this page and launch the resource

Investigate what makes something soluble by exploring the effects of intermolecular attractions and what properties are necessary in a solution to overcome them. Interactive models simulate the process of dissolution, allowing you to experiment with how external factors, such as heat, can affect a substance's solubility.

4. The Physical Setting

4D. The Structure of Matter
  • 4D/M1a. By the end of the 8th grade, students should know that all matter is made up of atoms, which are far too small to see directly through a microscope.
  • 4D/M1cd*. By the end of the 8th grade, students should know that atoms may link together in well-defined molecules, or may be packed together in crystal patterns. Different arrangements of atoms into groups compose all substances and determine the characteristic properties of substances.
  • 4D/M3ab. By the end of the 8th grade, students should know that atoms and molecules are perpetually in motion. Increased temperature means greater average energy of motion, so most substances expand when heated.
  • 4D/M3cd. By the end of the 8th grade, students should know that 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.
  • 4D/M4. By the end of the 8th grade, students should know that the temperature and acidity of a solution influence reaction rates. Many substances dissolve in water, which may greatly facilitate reactions between them.

11. Common Themes

11B. Models
  • 11B/M4** (BSL). By the end of the 8th grade, students should know that simulations are often useful in modeling events and processes.
11D. Scale
  • 11D/M3**. By the end of the 8th grade, students should know that natural phenomena often involve sizes, durations, and speeds that are extremely small or extremely large. These phenomena may be difficult to appreciate because they involve magnitudes far outside human experience.

12. Habits of Mind

12D. Communication Skills
  • 12D/M6**. By the end of the 8th grade, students should be able to present a brief scientific explanation orally or in writing that includes a claim and the evidence and reasoning that supports the claim.
