QUESTION: Dear Marie,
Do you have some good suggestions of biology: plant, animal, human science experiments that would work well with teenagers? Scientific methods must go with the experiments. Thanks! <
Donna
ANSWER: Dear Donna,
Marie is not online and I’ll help you instead of him. There are a lot of little things that can be done, but do you mean lab experiment or statistical analysis, etc.? Let us know what can be suitable for you teens, and we will do our best to send you some experiments to do.
Best，

QUESTION: Dear Gloria,
I need lab experiments. The teenage students and I will use data from these experiments to make charts, graphs, tables, etc. and to provide claims and evidence to explain more about the results. Thank you very much.
Donna
ANSWER:
Hi there,
Your best and easiest way is to do some chemistry experiments. Those are very easy and most probably you can do it in the lab and have charts, etc. for you. I do not have any particular one at the top of my head because I do cancer research and it is a bit more difficult than research for teenagers. I think you can look through these and see if you find something useful for you /chemistry/sezennur/experiments.htm
If not, get back to me and Marie, and we’ll look more. The good thing about this site is that it has the procedures that you can follow.
Good luck，
Gloria
