What makes the ocean blue but a glass of ocean water nearly colorless? Investigators prepare tubes of water to examine the color of water. Scholars discover the relationship between light absorption, color variations, and water depth as...

Introduce your classes to a fourth state of matter! Liquid crystals have a colorful sheen that changes based on different physical factors. Learners use this information to create a liquid crystal thermometer where the color of the...

It may be gruesome but somebody's got to do it! Young forensic scientists get a feel for what the job entails as they study blood spatter in seven experimental activites. They examine how spatter can be changed by release height,...

Jell-O® can help model the transmission of light through fiber optic cables. Young scientists use the jiggly dessert to make a waveguide to transmit a laser beam from one point to another. Their models help them learn the function...

Round and round in circles it goes! A hands-on activity has learners recreate a model of a convection cell. They watch as the difference in density of their materials creates a current.

Students can see light reflected and refracted in this demonstration. They will also discover the total internal reflection of light.

In this science fair project, use a globe and a heat lamp to investigate how the angle of the Sun affects global warming. This project includes the objective, background questions, a list of all the materials you'll need, and the...

Kids learn by experimenting with science. Project showing how the angle of the sun affects our temperature.

If your idea of a great weekend morning is taking some practice swings at a driving range, or heading out to the links to play a round, this could be a good project for you. This project is designed to answer the question, what is the...

An interactive simulation that teaches about polarity, electronegativity, and bonds by changing the electronegativity of atoms and bond angles in a molecule to see how it affects polarity. This simulation can either be downloaded or...

An interactive simulation that teaches about kinematics, air resistance, and parabolic curve by shooting a car out of a cannon while trying to hit a target. Observe how changes in angle, initial speed, mass, air resistance, and drag...

Students investigate how particle size and shape relate to the maximum slope angle the particles will maintain during a landslide.

All structures require a foundation to keep them from falling down. This is especially important when a structure is built on a hill or on a slope. In this science project, you will build a tower of Lego Duplos on slopes with different...

Airplane wings do not all have the same design. With this Science Buddies project you can design your own wings to see which offers the greatest lift. The Science Buddies project ideas are set up consistently beginning with an abstract,...

Here is an interesting project that could be approached from several different scientific angles: Environmental Science, Weather & Atmosphere, Chemistry, or Plant Biology. You can probably think of your own variations to emphasize...

This project presents an interesting puzzle. A disk of wood will float face-up, that is, with its circular cross-section parallel to the surface of the water. A long log of wood, however, floats with the circular cross-section...

Students "learn about vehicles, velocity, angles, and energy," as they participate in a variety of creative and hands-on activities, like building adjustable ramps, researching modes of transportation, and predicting "what transportation...

Looking for some hands-on activities to use with your students to teach reflection? This resource offers a couple of experiments on the angle of reflection and light absorption. This resource is in PDF form; requires Adobe Reader.

Taking advantage of free energy can reduce our dependence on fossil fuels, which are harmful to our environment. In this science fair project, you will work with a solar panel, which is a collector of free energy, and investigate how...

There's a lot to understand about the simple propeller to see how it affects lift and thrust in an airplane or helicopter. This Science Buddies project gives you lots of ideas on how to change the design of the propeller to achieve...

What colors do you see in a bubble? Why do you see colors in a bubble? Use this site to find out the answer to these questions with this easy experiment.

Children can look around corners with this homemade periscope. Great instructions at this Exploratorium site on how to build a periscope.

With this project you'll send ping pong balls flying through the air with a rubber-band powered catapult. This catapult makes it easy to reproduce the launch angle, and to measure the amount of force applied to the projectile. Armed with...

This lesson plan allows student to make a launch altitude tracker. Student will use a sighting tube and angle measurements to track the altitude of rockets that are launched.
