Bicycle Pump Pressure

Learners participate in a series of demonstrations about Bernoulli's principle. They explain how air pressure varies with air speed. They write a detailed lab report about the activity. This is a great way to explore this concept.

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 problem from a chemistry textbook is posed on the screen. In this problem, ethanol is used to illustrate how much energy, in joules, is required to change a substance from a liquid to a gas. The boiling point of ethanol is given, and...

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...

Students, in groups, create experiments to predict and prove what a change in pressure can do to objects exposed to the change. They use AppleWorks to write their hypotheses and the steps they need to conduct the experiment.

Investigate what is pushing on us. An intriguing lesson has pupils calculate the amount of force on various squares due to air pressure. Using the data, individuals create a graph in the third lesson of the Up, Up and Away unit...

Young scholars discuss ways they might visually see pressure differences, and work in groups to create experiments to predict and prove what a change in pressure can do to objects exposed to the change.

Introuduce your scientists to the differences in air at varying altitudes with a colorful explanatory graph. After some discussion, they view unbelievable footage of mountain-climbing Leo Houlding and a narrative about how he might do...

Young scholars examine air pressure. In this air pressure lesson, students perform a series of experiments to evaluate the effects of air pressure.

Do not let the pressure get to you. The first lesson in a unit of 22 introduces the concept of air pressure. Using background knowledge, the resource gives teachers the information they need to discuss how people measure air pressure and...
