Question: I Need An Idea For An 8th Grade Science Experiment! Please Help!?

I need an idea for an 8th grade Science experiment!

I have to have a hypothesis, a control, and only one variable. I need to be able to graph the data, and it needs to be safe for an 8th grader to do.

Help I can’t think of anything!

No volcanoes please.

Answer: Test the different ‘hand sanitizers’ vs natural essential oils product like ‘Purely Fresh’
Use petri dishs innoculated by touching with hand.
Control, untreated dish

Purely Fresh Hand Cleanser/Disinfectant

Handy Purse Size – A blend of Witch Hazel (Hamamelis virginiana) extract, Ethyl Alcohol, essential oils of Lavender (Lavandula angustifolia), distilled Lime (Citrus medica), Lemongrass (Cymbopogon citratus), Tea tree (Melaleuca alternifolia) with a dash of xanthan gum creates a gentle waterless hand disinfectant that smells great and is free of the skin irritants found in commercially produced waterless hand cleansers.
