Students examine buoyancy and fluid pressure. They conduct a series of fun experiments to discover the effects of pressure and explore how pressure differences can be used to float, lift, transport, or hold a material in place.

Students complete experiments with soda cans to examine the effect of pressure and air movement. They create low pressure and discuss its effects. They also examine thunderstorm safety rules.

Students examine forces that effect flight.  In this flight lesson students answer questions that are asked of them and the ones that they ask themselves. 

Students demonstrate how hail and rain are suspended in the air during a storm. In this lesson on storms and weather, students use a hair dryer and ping pong ball to demonstrate how hail and rain can be suspended in the air during a storm.

In this physical science worksheet, students write short responses for each scientific law in 14 different questions to obtain a merit badge.

Students examine how wind tunnels are used for research and development.  In this aerodynamics instructional activity students are given instructions on how to develop different types of wind tunnel.

Students experiment on Boyle's law using balloons and other common materials. For this chemistry lesson, students explain the relationship between pressure and volume. They solve problems relating to Boyle's Law.

Students examine the different kinds of propellers and their functions.  In this airplane instructional activity students build a hand made propeller.

Students examine the aerodynamics of a wing and how it generates lift.  In this flight lesson students complete several experiments including how to build a paper plane and how airfoils affect performance.

Pupils examine how wind can suspend rain and hail in clouds. They focus on safety precautions they can take to protect them from the hazards of thunderstorms.

Pupils explore the concept of Bernoullii's Principle and how it behaves. Have each student fold the piece of paper in half. Then have them place the paper like a tent on a smooth surface. Have them blow under it (they can use a straw if...

Examine in detail the Bernoulli Effect so students understand that faster-moving fluids mean the pressure is lower. Find the theory and its equation.

You can actually make objects come together by blowing air between them. This is a simple way of implementing Bernoulli's principle. Find out how wind changes air pressure to bring to objects together in this easy and fun science fair...

In-depth explanation of Bernoulli's Law, including a diagram of a Venturi tube and equations.

This simple lab demonstrates Bernoulli's Principle using a balloon, a tennis ball and a hair dryer.

Learn about the Bernoulli effect by building an airplane wing, or airfoil, and making it fly.

Provides a detailed explanation of how the Venturi Effect works in fluid mechanics and how it can be proven using Bernoulli's equation. Also discusses applications of the Venturi Effect in the real world.

PBS site allows users to get a front row seat at a pushing contest between fast-moving and slow-moving air.

In-depth explanation of Bernoulli's Principle and its applications. Diagrams and equations are included.

Discusses air flow around the wing of a plane and its effect upon the lift and drag forces. Focuses on the application of Bernoulli's principle to wing design and the subsequent airfoil shapes.

A question and answer regarding wind velocity and its effects on architectural design. A good site for applying the concept of the Venturi Effect.

The Tippy Tap hand-washing station is an inexpensive and effective device used extensively in the developing world. One shortcoming of the homemade device is that it must be manually refilled with water and therefore is of limited use in...

Laminar flow is explained at a basic level here at Exploratorium.com. Examples of things that use laminar flow are given. Links to related sites.

This site by the Illinois Institute of Technology lets students use a vacuum cleaner hose, ping pong balls, straws and other materials to investigate the effect of moving air upon the surfaces which it hits. Principles are applied as...
