Science experiments for middle school are meant to be fun and creative, but unfortunately some parents take them extremely seriously and force their children to do work rather than have fun. Kids should choose their own experiments and complete the majority of the experimenting and work on their own. This will allow them to learn a lot more about experimenting with science and writing up lab reports which will definitely become useful in high school and college.
- One science experiment for middle schoolers could deal with something as simple as mold. Mold growth is affected by moisture and several other variables, and the growth of mold can be fascinating if experiments are completed properly. Children should have a control group and an experiment group if they want to focus on moisture as their variable. The control group, which could just be a slice of bread, should be left in a dry and airtight container. The variable/test group should have some moisture applied to it on designated intervals. Record results and watch as the mold grows and transforms at two completely different rates.
- Another middle school science experiment could be to test different reaction times in different sexes. The student should choose a specific age group to test and make sure to control as many of the variables as possible. He or she should also test as many participants as possible in order to obtain the most accurate results. The test itself could be something as simple as having someone press a button to stop a timer as soon as they notice a change, which could be you turning off the lights or turning on the water.
- A third middle school science experiment could deal with age and the sense of smell. Control as many variables as possible, and test different age group's abilities to smell different types of odors. Students could have multiple odors, such as something sweet, something sour, and something rotten. Record the results and write up your report and you are finished.
- One more science experiment for middle school could be to test plant growth in different situations. Buy some seeds of the same plant, preferable one that grows rather rapidly. Place the seeds in different environments and test the results. For example, you could place one seed in the sun and water it daily, one seed in the dark and water it daily, and one seed in the dark with no water. You could vary the water, the light, the housing the seed is planted into, the type of soil, and several other factors in your experiment to make it more or less complex.
