8 or 9th grade level science project on plants,seed gemination, or soil?

Question

I want to do a Science Project that takes only 1,2, or 3 weeks. Nothing like different colored lights affecting the growth of a plant or plants growing in different amounts of light. I like doing things on seed germination, or something with soil, and/or mulch. Please help! thank you!
