Middle school science experiments should be more complex than the ones you would have done in elementary school. At this level, the science experiments you are doing will be preparing you for the more involved science projects you will be doing in high school, when you will most likely be entering science fairs to compete for prizes. By this grade, you will need to do your project mainly on your own and be able to explain your project in full, write a report and make up a display.
One of the interesting middle school science experiments is to see if the growth of a plant is affected by the amount of light it receives. For this project you will need three identical plants, three cabinets and three light sources, a 25 watt bulb, a 60 watt bulb and a 100 watt bulb. Mount one of the bulbs in each of the cabinets and label them so you know which bulb is in which cabinet. Then water them and check them once a day for about ten days and record your results in a chart.
Another great middle school project is to see how much starch different foods contain. You can accomplish this by getting a starch chart and a few different samples of popular foods. To test the foods, put a few drops of iodine solution (50% iodine/50% water) on each piece of food. If there is starch in the food the iodine will turn dark brown or blue-black. Record your findings on the starch chart.
