Hate to vacuum, but enjoy using a vacuum pump? Explore a lesson that starts with a demonstration of boiling water at various temperatures by using a vacuum pump. Then scholars design their own experiments to measure vapor pressure and...

Using PVC pipe and aquarium tubing, build an altitude tracker. Pupils then use the altitude tracker, along with a tangent table, to calculate the altitude of a launched rocket using the included data collection sheet.

Does the change in energy of matter lead to a change in mass? Upcoming chemists compare the mass of equal-volume, but different-temperature liquids and materials both before and after a chemical reaction has occurred. In another...

Young scientists get to the heart of the matter with this comprehensive review of the circulatory system. Addressing the different anatomical structures and processes involved in pumping blood through the human body, this worksheet is a...

Young scholars calculate the escape velocity of planets in our solar system and use that knowledge to calculate the escape velocity for NGC 2300 group. They then suggest reasons for the escape velocity to be higher than possible given...

Sal explains the concept of pressure, and what constitutes pressure, in this chemistry video. He points out that Pressure = Force/Area, and that if atomic particles inside any container begin to move faster, the pressure rises. In...

Vapor pressure is the focus of this chemistry video. Sal explains that, when molecules are "sticking together" a substance takes on a liquid, or a solid form. But when kinetic energy is increased, the molecules are forced apart and a...

Figuring out the partial pressures of various gases in a container is the focus of this chemistry video. Sal sets up a problem where a balloon is filled with three different types of gases: oxygen, hydrogen, and nitrogen. The goal is to...

Begin by discussing pressure and showing a video clip of James Cameron's record-setting deep-sea dive. Then assign lab groups to explore how depth affects pressure and to construct a manometer. There is another video to follow the...

From ancient Greek philosophers to early American Quakers, people have sought to understand the composition of matter for millennia. Follow along with this video as it explores the long scientific journey that eventually led to the...
