Home Scientist Brownie Badge

 Disclosure: There are some affiliate links below and I may receive commissions for purchases made through the links in this post, but these are all products I recommend. 

I am a chemist for work, so I was so excited to do this badge with my Brownies. I allowed each girl to do their own experiments because, why not? In our meetings, we utilize a lot of parental help. 90% of my parents are registered volunteers and are more than happy to help us, so they cleaned up the messes we made!

Each girl got some safety glasses and a lab coat to start.
