Your 7th grade science project is likely to be more involved than the projects you have done in previous years. The science fair at your school is probably more competitive for your age group, and there is a good chance your peers will be putting a lot more time and effort into their projects than they have in previous years. You will want to do the same for your project. There are endless possibilities when it comes to choosing a project to do.
One interesting idea for a 7th grade science project is to see which type of cheese will grow mold the fastest. This is a great project because it is not only interesting, but still fairly simple. There are so many different kinds of cheese out there, but you will only need to choose three or four types to experiment with, such as Parmesan, cottage cheese, and Swiss cheese to start with. Put a slice (or scoop in the case of the cottage cheese) of cheese onto a paper plate and set the three plates in the same area.
Make sure one of them is not going to get sun part of the day and the others are not. Be very careful to keep your experiment away from pets and small children as mold is bacteria and it can make people and animals very ill. After putting the samples in the safe place, check the cheese each day and see which one starts to mold first. Remember to dispose of it as soon as it starts to mold to avoid making anyone sick.
Another seventh grade science project idea might be to see if you can grow a plant without soil. You can try placing seeds in various things such as a wet paper towel, grass clippings, coffee grounds, or other similar substances to see if they will grow.
