Class Experience

I have a PhD in Microbiology but soon afterwards became certified to teach as I wanted to be with kids. I have many years experience teaching elementary and middle school science. I have taught science education classes in a teacher education department and even have taught PreK and Kindergarten science! I make my classes as hands-on, fun and rigorous as possible. 
Homework will come from the Water Science Workbook Packet
Materials/Supplies: Students will need a notebook for notes, activities, and assignments. In addition, they will need to purchase or order a small number of easily-obtainable materials. They will also need to purchase a printable water science workbook packet from (author Dr. David Purvis).
Learners will not need to use any apps or websites beyond the standard Outschool tools.

2.0     C-, but needs improvement
1.0     Little to no effort
40 minutes per week in class, and an estimated 1 - 2 hours per week outside of class.
