thumbnail One way to test for the presence of toxic compounds in a water sample is a bioassay. In a bioassay, a living organism serves as a detector for toxins—the same way canaries were used in coal mines to detect invisible toxic gases. In this project, water fleas (Daphnia magna), a freshwater crustacean, are used in a bioassay to monitor water quality. Many variations of this experiment are possible. Read more

thumbnail While looking at a package of dry yeast it is hard to believe that the package has organisms in it that are alive. But add the right ingredients and presto, the mixture becomes a bubbly, oozing, mess of life! What are the right ingredients? What does that yeast need to become active? Do this science project and figure it out for yourself! Read more

thumbnail Solar cells are popping up on rooftops everywhere these days and are a model for clean, renewable energy. Did you ever look at those solar panels and wonder how we can get electricity produced by solar cells when the sun is not shining? It is a great question because solar panels do not produce electricity when it is dark outside. One strategy to overcome this challenge is to store the energy produced by solar cells during the day in the form of a fuel that can be used at a later time. In… Read more

Safety Adult supervision is recommended. Use caution when connecting the four 9V batteries. Ensure that the wires/connectors do not come in contact with each other to cause a short or the batteries will become VERY hot and can possibly cause burns. Cobalt nitrate can cause skin and eye irritation. It is recommended to wear disposable gloves when handling cobalt nitrate.

thumbnail Chromatography is a method used to separate mixtures of compounds and to identify each compound in the mixture. You may have separated the different inks in a black marker by using a strip of paper and water. There are many different types of chromatography: paper, thin-layer, high-performance thin-layer, gas, and more. You will be using paper or thin-layer chromatography to analyze the compounds from different plants. Chromatography is used by analytical chemists, organic chemists, and many… Read more

In this project you can use archived satellite tracking data to learn about activity patterns of harbor porpoises. How far do they travel? Can you find patterns in the routes individual animals take? Can you correlate their route with environmental factors such as currents or ocean temperatures? If you're interested in marine mammals, this might be a good project for you. Read more

You might not know it, but a lake without algae would be a very dull place. If there were no algae, there would be no small animals feeding on the algae, and there wouldn't be any fish eating the small animals that eat the algae. You might conclude that since some algae is good, more algae is even better, but algae growth has a down side. If there is too much algae, they can deplete the oxygen in the water, killing off other species in the water. What is one culprit that leads to algal growth?… Read more

Time Required Very Long (1+ months)
Material Availability You will need access to a pond or a lake from which to collect water. Students who do not have access to a pond or a lake might want to look at some of the variations, at the end of the project, which use purchased algae cultures.

thumbnail We've all heard that hurricanes draw their immense power from warm ocean waters. Of course, many factors contribute to the formation and growth of a hurricane, but can we expect to find that the warmer the water, the stronger the hurricane will be? This project shows you how to use online data archives to investigate this question. Read more

thumbnail Generating power from mud sounds like science fiction, but it is actually real science, and a promising source of alternative energy. Topsoil is packed with bacteria that generate electricity when placed in a microbial fuel cell. Because such bacteria-laden soil is found almost everywhere on Earth, microbial fuel cells can make clean, renewable electricity nearly anyplace around the globe. They are an up-and-coming technology that scientists and engineers are working on making even more… Read more

Prerequisites Having used a voltmeter/multimeter before is helpful, but not required.
Material Availability The microbial fuel cell needs to be special ordered from Science Buddies. See the Materials tab for details.
Cost Average ($50 - $100)
Safety Be sure to wear the gloves supplied with the kit when handling the microbial fuel cell's electrodes (its cathode and anode). The electrodes are made of a conductive material called graphite fiber and should not be placed near electronics, power plugs, or have their fibers dispersed in the air. The fibers will cause electrical shortages when in contact with electronics.
