5th grade science projects are a little more involved than previous years, and are generally done by the students with little help from their teachers or parents. They may need some guidance along the way, but most of the work should be done by the student. Fifth grade students are old enough to handle the responsibility of choosing a topic, asking a question and experimenting to find the answer to their question. It can be a lot of fun for parents and teachers as well as the students. This is really the first year they will be coming up with the ideas and doing the work themselves, so it is quite interesting to see what sort of projects they will choose.

5th grade science projects can include seeing which brand of soda will decay a previously lost tooth the most. To do this experiment, you will need several different brands of soda, some teeth that you have lost recently, a few small dishes or cups, and a pen and paper to make a chart to record your findings.

To begin, you can set up the various bowls or cups and place a tooth in each one. Next, add a different brand of pop to each bowl or cup. Be sure to label each one so you know what brand of pop is in it. Place them in an out-of-the-way place where they will not be disturbed and check them each day to see if there is any decay starting. Once you see some decay beginning, you can mark it on your chart and then see which one gets the most decay.
