High School Biology Experiment Ideas

By Jennifer Eblin, eHow Contributor

1.

One idea involves testing the effects of different substances on plants.

High school level biology covers all aspects of biology, including animals, plant life and humans. That should mean it's easy to come up with a

science fair project or a classroom research project, but the amount of

topics sometimes makes it even harder. When you first start researching, you'll find thousands of ideas and it's difficult to decide which one is best for your situation. Provided that you know what you want to do and what your teacher or judges are looking for, it's easy to come up with a great

biology experiment.

Effects on Plants

2. Test the effects of different substances on plants. Place plants from the

same source in pots of the same size, then use different types of materials.

You can test different types of potting soil against regular dirt or use the same type of potting soil and test other substances. Water the plants with different types of bottled water and tap water from your home and other homes or add a small amount of vinegar and other liquids to see how the plants react to those substances. Observe the effects of the different

substances on the plants and measure how quickly each plant grows in comparison to the others.

Water Bottles

3. Test the amount of germs and toxins found when you refill a water bottle.

Start by taking a sample swab from the outside lip of the bottle and looking at the water under a microscope for any bacteria or impurities. Then drink from the bottle as you otherwise would and test the bottle each time you refill it with extra water. Student athletes can even use the same plastic
