Middle School Science Experiments

Middle school science experiments tend to be a bit more involved than elementary school. This is to prepare you for high school science fairs which can be quite competitive and require much more hard work than elementary school and middle school.

Materials Needed:

Three of the same plants
Three boxes or cabinets to use as test rooms
Three different light sources that will be mounted inside the boxes or cabinets, 25 watt bulb, 60 watt bulb, 100 watt bulb

How Does Light Affect Plant Growth
Experiment: Is a plant’s growth affected by the amount of light it receives?

Middle school experiments that can be quite interesting are to see if a plant’s growth is affected by the amount of light it receives. For this project, you will need three plants of the same variety, shape and size, and three boxes or preferably cabinets to use as test rooms and three different bulbs to be mounted inside the cabinets; a 25 watt bulb, a 60 watt bulb and a 100 watt bulb. You then need to mount the light bulbs in the cabinets, making sure they’re going to be far enough away from the plants that they won’t cause heat damage to them. Then, place the three identical plants in the three test rooms. Be sure to label each cabinet 25, 60 and 100 so you know which cabinet has which bulb in it. Make sure that the test rooms have proper ventilation. Water and inspect your plants every day and record your results for at least ten days. You will then see if the amount of light that each plant receives helps it grow faster, or makes it grow slower than the others. It will be helpful to make a chart to keep track of your results.
