Showing Results for air

In this science fair project, we learn how air molecules move as a result of density, convection, and air currents.

This science fair project idea provides evidence that air is everywhere and takes up space.

Free science fair project idea that examines air pollution in local environments. Particles are trapped by petroleum jelly on microscope slides.

The goal of this science fair experiment is to demonstrate the effects of air pressure on objects and analyze applications of air pressure principles.

This project examines which style of central-air system filter traps the most particles from the air.

Is there more air particulate matter in an urban or rural environment? Test your knowledge with this science fair project.

The objective of this science fair project is to examine the basic principles of air pressure using simple materials like a balloon, straw and string.

Can the force of air be used to propel a vehicle? This science experiment provides step-by-step instructions to help you answer this question.

In this science fair projects, students will grow out the bacteria that collect on air conditioner filters.

Compare air temperature with the infrared temperature from a reflecting surface at different times of the day, in shade and in sunlight.

This project will examine the relationship between materials and air resistance.

The objective this science fair project is to determine whether a bigger bag will allow a homemade hot air balloon to fly higher than smaller bag.

Science fair project that determines what percentage of air is made up of oxygen by examining the chemical reaction between oxygen and rust.

This classic children's game demonstrates how sound travels through air vs. through a solid.

What's the relationship between temperature, air humidity and static electricity? Kids will find out with this free static electricity science fair project.

Air resistance is a crucial factor when designing a parachute. In this science fair project, students find what type of material works best as a parachute.

In this air pressure science experiment with a balloon and a jar, children will use heat to create a partial vacuum and suck a balloon into a jar.

How fast does light travel in different mediums? Kids conduct a cool refraction experiment in materials like water and air for this science fair project.

The purpose of this science project is to determine whether the amount of air in a soccer ball affects how far it goes when kicked.

Measure the porosity of rocks by submerging them in water. Measure how much water each rock "drank," by measuring the difference in water volume.

In this science fair project, students use hot and cold water to simulate what happens when a warm front meets a cold one.

Marshmallows are made of sugar, water, and air pockets. Since the marshmallow is flexible, will air pressure cause it to expand when heated in a microwave?

This project explores the interaction between air pressure and playing surface in determining a basketballâs bounce.

Determine the relationship between the speed of a sound and the temperature of the air it passes through.

This cool air pressure demonstration has kids break a ruler using only a newspaper and atmospheric pressure.

Determine how wind speed affects the stability of a kite and the ease of getting it into the air.

In this Bernoulli's Principle experiment, you'll learn how an increase in the speed of a fluid, like air, decreases pressure.

This science fair project idea teaches how the gases and pollution in the air affect the earth's atmosphere temperature.

This cool science fair project teaches kids about temperature, density and buoyancy using balloons that float with normal air. No helium required!

The objective of this science fair project idea is to determine if sound travels best through the air, water or a solid.
