Botany Experiments


Montessori Botany Command Cards for the biology chapters of work. The cards are organized by botany chapter, so when you are working on leaf lessons, you can easily pull out the leaf experiments! The experiments are based on Dr. Montessori’s original botany experiments, but have been updated or removed where needed. I have added some wholly new experiments as well that will fit seamlessly into your established botany curriculum. Names of the traditional experiments have been rephrased from their original titles into hypothesis questions.

I wrote a blog post for tips on setting up your science experiment shelves here.
