Making decisions on your own is hard enough, but when other people get involved and try to pressure you one way or another it can be even harder. When people your own age try to influence how you act, it's called peer pressure. It's...

Focuses on the basics of the disease high blood pressure (hypertension) such as risk factors, signs, effects, and control; specifically in women.

Animated resource helps young researchers understand air pressure and how we measure it.

When a balloon is filled to near bursting with SF6 is left in air, it will often burst after a period of time. This is because the smaller N2 molecules diffuses into the balloon while the larger SF6 molecules remains causing the balloon...

A lab experiment in a series of experiments that explores hurricanes. Students learn about the effects of the differences in air pressure with hand-on experiments and demonstrations

Investigate how selection pressures and natural selection influence populations growth with this computer model. Understand how a population changes when selection pressures are in conflict. Perform the virtual lab to see what happens to...

Use this tutorial to understand Dalton's Law of partial pressure, and then answer some interactive practice questions to review the material.
