be excellent to each other & don't run with scissors
While building boxes to fit a specific amount of sand with 5% extra space, each team had to have a design interview before they could proceed to build their final product.
During the interview I asked many questions about their process and asked for specifics about tools used, measurements made, and design ideas. While students were able to have their engineering journal for backup they had to conduct the interview face to face with me. Everyone did great!
Creation is not easy, and creating on a spec is harder still. In Physical Science students are tasked to design, document, and test a box that they build for 400.g of sand with only 5% extra volume ±0.5%.
So after the initial design & documentation students paired up today to discuss and listen what went well and what could be improved for next time. 
I’m fortunate to work with a great team of physical science teachers (hi Mrs. D’Onofrio, Mrs. Hilfinger, & Dr. Holmes!). So all of the curriculum we’re doing right now has been a group design & writing effort.
Learning measurement, observation, and documentation through building (boxes to hold sand to specific dimensions)is what 9th grade science is doing right now.
