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...

Given a particular direction and velocity, what force can make a ball swerve into a goal? This visually engaging video illustrates the physics that occur when a ball rotates on its axis while moving in a particular direction, also known...

Can your class predict the weather? Show them how they can come close with a lesson about creating weather instruments, including weather vanes, barometers, wind socks, anemometers, and thermometers. Kids research weather patterns and...

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...

Demonstrate lift to the class that is studying aerodynamics. In the stream of air produced by a blow dryer, little physicists place a wad of tissue paper and a spherical figure to compare. Or, if you have a vacuum cleaner and beach ball,...

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...

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...

Make a hovercraft out of a compact disc, a balloon, and a few other materials. This is an activity that every physical science learner in your class can make if they bring a sports drink pop-top bottle to class. It will help them...

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...

Here is an outstanding experiment for young scientists! Film canisters (remember those?) are filled with water, and an Alka Seltzer tablet is dropped in. Explosions occur very quickly! The challenge for youngsters is to find out what the...

Make a hovercraft out of a compact disc, a balloon, and a few other materials. This is an activity that every physical science learner in your class can make if they bring a sports drink pop-top bottle to class. It will help them...

Throughout this earth science exam, high-school geologists complete a series of multiple choice and short answer questions about the solar system, atmosphere, and earth system. This is an amazing test, as are all of the exams developed...

Push the envelope with this lesson on atmospheric pressure! Your physics or geology juniors will be amazed at your super-human ability as you demonstrate the breaking of a stick using a newspaper! They also work with peers to construct a...

Diagrams bring barometers to light in this PowerPoint. Several slides explain the structure and function of this apparatus. The relationship of air pressure to the processes of evaporation and boiling are also explained. This would be an...

Which will make it fly better? Individuals build paper rockets with fins that are launched using straws. After determining an average flight distance, they make adjustments, such as size and location of fins, and try again. A second...

Stay calm under the pressure. Learners participate in four activities that demonstrate aspects of air pressure. Two activities allow pupils to experience atmospheric pressure and its ability to provide a push. The other two demonstrate...

Decide whether to learn about weather. An illuminating lesson has scholars first watch video clips and discuss the difference between weather and climate. Using their newfound knowledge, they create analogies to illustrate this...

There are many interactions among living things and their surroundings. Scholars learn about Earth, the moon, and the sun and how they relate to the solar system by completing a reading. They also investigate basics of physical science...
