It can be a challenge to come up with a middle school science fair project idea. There is fierce competition to come up with the coolest idea, plus you need a topic that is considered appropriate for your educational level. College projects are your chance to shine. Students in middle schools may do alright with projects that describe or model phenomena, but you will excel in case you can answer a question or solve a problem. Try to propose a hypothesis and test it. Aim for a typed presentation with visual aids, such as pictures or physical examples. Choose a project you can do fairly quickly, to give you time to work on the report (no longer than a month). Schools may prohibit projects using hazardous chemicals or animals, so play it safe and avoid anything that might raise red flags with your teacher. Can you significantly affect your household water bill or electric bill (water or energy usage) by making a change in you or your family's behavior? You might track changes you are making, like shorter showers or turning off lights, and record the utility usage, for example. What household waste materials might be used to filter water? Examples of materials you might try would include coffee grounds.

Middle school science fair projects

Does the power of a microwave affect how well it makes popcorn? Do all brands of diapers absorb the same amount of liquid? Does it matter what the liquid is (water as opposed to juice or... um.. urine)? How permanent are permanent markers? What solvents (e.g., water, alcohol, vinegar, detergent solution) will remove the ink? Do different brands/types of markers produce the same results? How do different factors affect seed germination? Factors that you could test include the intensity, duration, or type of light, the temperature, the amount of water, the presence/absence of certain chemicals, or the presence/absence of soil. You can look at the percentage of seeds that germinate or the rate at which seeds germinate. What steps can you take to maximize crystal size? You can affect vibration, humidity, temperature, rate of evaporation, purity of your growth medium, and time allowed for crystal growth. Is a seed affected by its size? Do different size seeds have different germination rates or percentages? Does seed size affect the growth rate or final size of a plant? How are different soils affected by erosion? You can make your own wind or water and evaluate the effects on soil. If you have access to a very cold freezer, you can look at the effects of freeze and thaw cycles. How close does a plant have to be to a pesticide for it to work? What factors influence the effectiveness of a pesticide (rain? light? wind?)? How much can you dilute a pesticide while retaining its effectiveness? How effective are natural pest deterrents?
