Blow your class away with a gust of humor as they watch this video about air pressure and wind. Along the way, they find that the density of air (as determined by temperature, altitude, and water vapor content) leads to air pressure...

Learners use an interactive simulation to explore the connection between force and air pressure. They adjust the mass of a vehicle and air pressure in its tires and predict the result. As the vehicle's mass increases, the tire pressure...

Do you work better under pressure? Pupils explore pressure when altering fluid density, gravity, container shape, and volume. Units can be converted to kPa, atm, and psi. To finish, scholars describe pressure as a function of depth,...

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...

Introducing your class to weather concepts is a breeze with this fresh film! It differentiates between weather and climate, describes the factors that affect weather (temperature, air pressure and humidity), and displays Earth's climate...

Concise, yet complete, this set of seven slides describes with photos and text the different basic instruments for measuring weather factors. After viewing, young meteorologists will be able to talk about how to measure humidity, wind...

We can't see most gases and we can't see things at the molecular level — but that's about to change! A simulation shows pupils the activity of molecules in a gas. The simulation allows scholars to vary the volume, heat, and...

For this audio power amplifier worksheet, learners answer five questions about class A amplifiers, sound pressure, crossover distortion, and amplifier design.

While scientists have identified seven states of matter, these puzzles cover the most common three. Scholars match the properties, particle motion, and particle picture to each type of matter. Three Sudoku-style puzzles review the data...

This online, interactive quiz highlights 10 English sayings. The adage is bolded, and learners must choose one of three options that correctly highlight the adage's meaning. What's great is that the user can access immediate feedback by...

For this weather affecting headaches worksheet, learners read the article, answer true and false questions, complete synonym matching, complete phrase matching, complete a gap fill, answer short answer questions, answer discussion...

In this weather instructional activity, learners click on the links in the questions about weather to find the answers to the questions and then come back and answer the questions. Students answer 17 questions total.

Engage visual and auditory students with a 4-minute video on tornadoes, paired with a comprehension note and activity guide. Learners watch the video and then fill in 15 pieces of information in a chart; determine if 12 statements are...

In this ocean activity, students complete a 13 question multiple choice on-line interactive quiz about ocean currents. Prior knowledge is assumed.

For this weather worksheet, students complete questions to a quiz about the weather. Students complete 5 questions in the weather quiz.

[Free Registration/Login Required] Uncover the relationship between pressure, force, and contact area in the context of a fire truck. Play with vehicle mass, number of tires, and guage pressure with this simulation to see what...

[Free Registration/Login Required] Observe what happens to the barometer as the weather changes from clear, to mixed, to overcast. Then answer a challenge question about the topic.

Students studying pressure will better understand its concepts with this virtual experiment that tests how pressure changes in air and water as the fluids, gravity, container shape, and volume changes.

Make a wind vane, rain gauge, and barometer and learn how to measure wind direction, rainfall, and air pressure.

Adjust the altitude and temperature in this simulation to observe how gas pressure is affected by these changes.

Explore why it is difficult to pull back on a capped syringe and why the plunger moves back in when you let go.

An upward force called lift acts on the airplane and opposes the downward forces of gravity. The lift force allows the airplane to get off the ground and stay in the air. Watch the simulation to see how this works.

A Java applet which allows the visitor to investigate the physical parameters associated with the individual strokes of a 4-stroke gasoline engine. Visitors enter parameters such as exhaust temperature, fuel ratio, and ambient pressure...

[Free Registration/Login Required] Ever lost a balloon that floated into the air? In this simulation learn how to combined gas law could help you understand the balloon's motion.
