Force and Pressure

In this pressure activity, students find the pressure of objects using the equation for pressure. They find the pressure of air in the atmosphere and the pressure of water in the ocean at different depths.

A short PowerPoint to help increase pupils' understanding of pressure. A number of pictures show different types of shoes and open a discussion of how force from a body is applied over different areas, (which translates into different...

We all have standards and scientists are no exception. Presentation covers standard temperature, standard pressure, temperature conversions, and absolute zero. It explains pressure using pascals, mm of mercury, atmosphere, and torr, then...

A blow dryer and ping pong balls are all you need to demonstrate the amazing properties of air flow. In this demonstration, Spangler has a little boy as his assistant. Together, they make ping pong balls, a beach ball, and a roll of...

A blow dryer and ping pong balls are all you need to demonstrate the amazing properties of air flow. In this demonstration, Spangler has a three year old boy as his assistant. Together, they make ping pong balls, a beach ball, and a roll...

It's amazing how easy it is to forget that every second of our lives we are being pushed on by an uncountable number air molecules. Explore with your class the concept of air pressure and how it affects our bodies, the earth's...

How can people control a hot air balloon? The simple simulation allows scholars to adjust the payload mass, burner, and vent position on a hot air balloon and observe the changes in velocity and altitude over time. Challenge questions...

One day supersonic flight may be possible. Watch a video that walks viewers through the history of air flight and the possibility of reaching supersonic speeds. Until then, travelers should get comfortable with ten-hour flights across...

Explore the center of gravity with your science class as they create a deadfall trap with common materials. They research the concepts of energy conservation and gravitational force before dividing into small groups to create a model of...

Humans aren't the only species to build structures with air conditioning—we weren't even the first! The video explains how a variety of species that live under and above ground design their structures to allow for air circulation. It...
