The oceans contain both the earth's largest and smallest organisms. Interestingly they share a delicate relationship linked together by what they eat. The largest of the ocean's inhabitants, the Blue Whale, eats very small plankton, which themselves eat even smaller phytoplankton. In this experiment you can learn how to collect your own plankton samples and see the wonderful diversity in shape and form of planktonic organisms.

Improve the design of a very simple aircraft, the whirlybird, and learn about hydrodynamics and biomimicry in this science experiment. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction, followed by a section on terms, concepts, and questions, bibliography, list of materials and equipment, experimental procedure, suggestions on how to vary the experiment, plus a focus on the sort of careers this experiment might relate to.

In this science fair project, use a calorimeter with an attached heating element to measure how water responds to added thermal energy.

Water creates a lot of energy, just look at the Grand Canyon. In this science fair project, you will demonstrate the power of water by converting the kinetic energy in moving water to mechanical energy, which will lift a small weight.

You may have heard the expression, "You can't get blood from a stone." But what about oil? Can you get petroleum oil from a stone? In this geology science fair project, you'll find out what kinds of stones make the best storage rocks for oil. You'll see which ones soak up oil the fastest, and which ones can hold the most oil. Can a hard rock really act like a soft sponge -- maybe SpongeBob SquarePants could change his name to RockBob SquarePants? Try this science fair project and find out.

At the end of your experiment you should review all of the data you have collected. See samples of data analysis charts and graphs. Find out what makes for a good chart or graph using the self-grading rubrics.

Find out what variables are in a scientific investigation and what the difference is between an independent, dependent, and controlled variable. Look at samples of different types of variables and find out what makes a good variable.

What does it take to launch a satellite to explore Mars, or a mission to the moon? This project has several possible variations for exploring the physics of rockets. This is rocket science.

The oceans are a precious natural resource, part of Earth's carbon cycle. But what happens if the oceans absorb too much carbon dioxide? Many scientists are concerned that the increased absorption of carbon dioxide is causing them to become acidic. What impact does that have on the marine life? In this ocean science fair project, you will demonstrate ocean acidification and investigate the effect on the shells of marine life.

This Science Buddies project asks that you identify different kinds of bridges, discover why they are built as they are, and then build three different bridges of your own out of balsa wood. See which one you think can bear the heaviest load. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction, followed by a section on terms, concepts, and questions, bibliography, list of materials and equipment, experimental procedure, suggestions on how to vary the experiment, plus a focus on the sort of careers this experiment might relate to.

You might think that plants and animals have little in common with batteries, springs, or slingshots, but they actually do have something in common. Both living and non-living things store and transfer energy from one form to another. In this physics science fair project, you'll investigate this energy storage and transfer, not in a plant or animal, but in bouncy balls. You'll find out if there are limits on how much energy can be stored and if there are losses when the energy is transferred.

You might know that we are able to get free energy from the Sun, the wind, and water, but we can also get free energy from Earth itself. This source of energy is called geothermal energy and it is all about taking advantage of the heat within Earth. So try this science fair project out and find out how to use the heat that lies beneath your feet.

Has anyone ever told you that you have a magnetic personality? Have you ever heard that opposites attract? These common phrases are both based on the properties of magnets and magnetic electricity. In this science fair project, learn how to make your own magnets out of nails and batteries.
