The project goal is to find out if cooked beans will grow the same as raw beans. The idea, or hypothesis, is that boiled beans will contain more water and fewer bacteria, so therefore they may grow better than raw beans. Plant raw beans as a control group and boil several beans for different lengths of time. Create a journal and log the progress of each bean. If possible, take pictures of the progress.
Create a homemade stethoscope using a garden hose, modeling clay and paper. Cut a garden hose on both ends after creating two funnels out of paper. Attach the funnels to the ends of the hose with modeling clay or tape. Document in a journal the effect that the homemade stethoscope has on household sounds. Are they easier to hear with the stethoscope? Do they sound louder? Are the sounds clearer?
Use colored water to see how white carnations soak up water and document where it goes. Pour ½ cup of water into a vase and add 20 drops of food coloring. Stir the water until food coloring is completely dissolved. Using a sharp knife, cut the stems of several white carnations at a 45 degree angle. Immediately place the carnations into the colored water. Document the carnations at the beginning of the experiment and again at regular intervals, such as 1 hour, 2 hours, 4 hours, 24 hours, and so on.
