Kids just get tired of doing the same old science fair projects. There’s one about volcanoes and another about eggs and another using baking soda. But it does not have to be this way. There are science fair projects that are really different from the usual, and very kid friendly.
For example consider a science fair project which helps you determine whether music will have any affect on blood pressure. Can you imagine how much fun the youngsters will have playing different types of music and measuring your blood pressure to see what affect it has? Will Beethoven and Bach cause pressure to go up or down? What about hard rock music? Frank Sinatra or Barbra Streisand? Will women react differently then men? Will boys respond in a different manner than girls? These are all interesting hypotheses for science fair projects. The research that your student does will provide the answers to these interesting questions. There is a website called Science Made Simple which can provide some more ideas.
Did you ever wonder who has a better memory, a man or a woman? Or does a girl remember things better than a boy? All of this type of experimenting can be done in another science fair project on the subject of memory. The student will gather his or her subjects and put them thru a series of tests and drills testing their ability to remember things. The science fair project on the subject of memory can be as simple or as complicated as the student wishes. Different levels of involvement are appropriate for different grades when doing science fair projects.
After all, memory is a function of the brain’s ability to retain information. There are many types of memory based on duration, nature and retrieval of perceived items, which may include encoding, storage and retrieval. There is for example short term memory which refers to the exact time that something is perceived, and there is long term memory which can go on for many years. You may forget a seven digit string of numbers in a short time, but you may remember your old telephone number for many years after you have discarded that number.
These are just a few suggestions for your science fair, beyond the usual boring choices. If you search the web and think about your interests, you are sure to find many more interesting topics.
