Subject: Mathematics (9 - 12), or Science (9 - 12)
Title: What's Wrong With Global Climate Change? I Like it Warm!
Description: Students will identify factors that affect the solubility of a salt and test one of the factors (temperature). They will apply their experience to ocean salinity, the effects of temperature on the composition of ocean water, and what effects that could have.

Subject: Science (8 - 12)
Title: Mentos, Soda, and Nucleation
Description: In this lesson, Mentos candy and different types of soda are used to show examples of nucleation, surface tension, surface area, polar attractions, and supersaturated materials. A video will be used to show the examples and the students will then work in groups to determine what their hypothesis is about what is happening and why. The students will be given a chance to debate with other students about why their hypothesis is correct. This lesson could be used in eighth grade physical science, physical science, chemistry, and/or physics.

Subject: Health, Science
Title: Antibacterial Pollution
Description: In this Science Update, from Science NetLinks, you'll hear about the potential environmental effects of common household products. A lot of household products nowadays claim to be antibacterial--containing compounds that kill viruses, bacteria, and other germs on contact. But what happens to these compounds when they get washed down the drain? Science Updates are audio interviews with scientists and are accompanied by a set of questions as well as links to related Science NetLinks lessons and other related resources.

Title: Acid Stomach
Description: This Science NetLinks lesson is intended for a high-school introductory chemistry class or health class. The lesson begins with the reading of an article on the history of the development of aspirin. Students then complete a lab that compares the reaction of regular aspirin, buffered aspirin, and enteric aspirin in neutral, acidic, and basic solutions. They then analyze the results of the experiment to gain insight into how this information was used by researchers to solve some of the problems associated with aspirin. To complete the lesson, students must understand acids and bases.

pH Scale
This website provides an interactive tool where students test the pH of things like coffee, spit, and soap to determine whether each is acidic, basic, or neutral. They can actually visualize the relative number of hydroxide ions and hydronium ions in solution, switch between logarithmic and linear scale, and investigate whether changing the volume or diluting with water affects the pH of a substance.
