Teachers Being Students: How Many Molecules Are in a Drop of Water?

Middle school students are often afraid of being perceived as stupid when trying to solve problems in class. When they see adults, in this case their teachers, go through the same struggles, they are more willing in the future to test and share their ideas. I want to thank the very courageous non-science teachers at my school for volunteering to be a part of this video. This activity covers NGSS practices: (2) Developing and using models. (5) Using mathematics and computational thinking. It also covers the NGSS crosscutting concepts: (3) Scale, proportion, and quantity.
