Question: Teachers, what can I do to increase my effectiveness in volunteering as a science resource person?

I would appreciate helpful suggestions. For the second year I will be responding to a request to help a 4th grade teacher and a 7th grade teacher (not the teachers I helped last year) by bringing to their classrooms weekly one-hour demonstrations and experiments, principally in the physical sciences. I already know eighty percent of the students. I will do the obvious: read the textbooks, encourage the teachers to choose my topics, and arrive properly prepared with a lesson plan and student worksheets or handouts.

What am I overlooking? What would worry you if I were coming to your class instead of theirs?

Answer: An hour is a long time for a 4th grade demo… especially @ the beginning of the year. Some will need all the time, some will not. I would suggest that you have @ least 2 different levels of worksheets (hopefully not busy sheets) for those that need a challenge as well as those on grade level. For those below grade level I would suggest an aid to help read and follow with them the lesson you are presenting. I would also have some additional material for those that finish first that would keep them busy as to not bother those students still involved with learning.

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.

Question: Catalysis and Chemistry Experiments for kids (science fair)?

I would like to ask if anybody has some suggestions for catalysis experiments for kids, namely with activated carbon. Does it adsorb for example some colored compoud of water or so? Or alternatively could you suggest a website where I can find suitable information? Thank you!

Answer: i don’t know why you specifically want the experament to do with carbon, but i’m sure you can find what you want here:
