Free Science Fair Projects

Free science fair projects can be a lot of fun since nobody wants to spend a lot of money on supplies for projects. Below is one of several engaging free science fair projects. And, free is one of the best kinds of science fair projects there is!

Research: All over the world, there are farms and agricultural centres. All of these farms and centres plant raw seeds, which turn into the vegetables that we eat. However cooking beans for a few minutes may make them more fertile. Another benefit that cooking the beans may destroy harmful bacteria, which would also result in healthier plants. It's possible that it could also quicken the process by destroying all of the unwanted material. To learn from this experiment, the measures must be accurate and the information must be correct.

Hypothesis: When a food is boiled, it will destroy bacteria and unwanted material. This means that planting cooked beans may quicken the process as there is no bacteria and unwanted materials to retard the growth of the plant. The beans that have been cooked longer should grow better when planted cooked than those that are planted less cooked or not cooked at all.

Material: This experiment uses lentil beans.

Procedure: Using half a pound of beans place them in a pot that is filled 1/3 with water. Take seven glass dishes and label them A-G. Use paper towels to line the bottom of the glass dishes. Take a spoonful of beans and place them in glass dish A. Do not cook this sample at all. Start boiling the pot of beans. Remove some beans after five minutes and place them into glass dish B. Record that these beans have only been cooked for a few minutes.

Then wait for ten minutes and put a spoonful of beans into glass dish C. Record that these beans have been cooked for ten minutes At the fifteen minute mark, take a spoonful of beans and place them into glass dish D. Record that these beans have been cooked for fifteen minutes. Wait another five minutes and place a spoonful into glass dish E. Record that these beans have been cooked for twenty minutes. Wait another five minutes and place a spoonful into glass dish F.

Record that this sample has been cooked for twenty-five minutes. The last sample will be taken out five minutes later. This spoonful will be placed in glass dish G. Record that these beans have been cooked for thirty minutes. After cooking the beans, take seven damp paper towels and lay them on top of the beans to keep them moist. Lay them beside a window so they can receive sunlight. Water them daily to keep them moist for four or five days and wait for the results.

There are many other free science fair projects. Use the free science fair project outline above or come up with your own variation. When it comes to free science fair projects, you're only limited by your own creativity.
