Let's Weigh Air

Why do you weigh more in space? Each individual in your class explores this question and others as they determine the mass and weight of different objects using two types of scales. They perform conversions and discuss their results,...

I would weigh less on the moon? Send me there, then! On the top of the first page, a cartoon image demonstrates the difference between Earth and the moon. It then goes on to describe weight and mass and provides five practice problems...

Learners examine Boyle's Law by analyzing experimental results with a hands-on lesson that provides a set of four experiments that illustrate the relationship between pressure and volume of gases. Groups analyze results using...

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...

Does it feel a little humid in here? Learners assume the role of water vapor in the atmosphere as they explore the differences between warm and cold air. They roll dice to determine their level of energy, which determines if they stay...

Take your class out to visit your automobile and use the tires to compute the weight of the vehicle. This is done by measuring the surface of the tire meeting the ground and the air pressure. This is a fun lesson in the relationship...

Can you feel the weight of the air on your shoulders? Your classes may not believe that air has weight. A straightforward experiment asks individuals to weigh a bottle before and after adding air. Their results may surprise them!

How high did the ball go? Engineering teams build a working pneumatic system that launches a ball into the air. The teams vary the amount of pressure and determine the accompanying height of the ball. An extension of building a device to...

You don't need a scale to determine weight. This activity provides a way to use the concepts of air pressure and surface area to determine the weight of a vehicle by calculating the amount of weight each tire supports.

Do not let the pressure get to you. The first instructional activity 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...
