We're off to a great start in the Middle School Science & Engineering classroom!
After getting to know each other, we have jumped right into our first unit on heat and thermodynamics. This year our anchor project for this unit is the construction of solar ovens. The kids are learning the concepts, laws, and terminology relevant to this task (while reviewing the steps of the Scientific Method), and are nearing the construction phase.
We plan to have in-class "build days" this coming Thursday and the following Monday, before demonstrating our ovens on Tuesday the 10th. For the demonstration, students are encouraged to bring SIMPLE snacks to warm up. Things like nachos, s'mores, quesadillas, etc are ideal. We do not want any uncooked meat or eggs, for obvious reasons.
In terms of the materials for the construction, the class will be providing either shoe boxes or pizza boxes, plastic wrap, black construction paper, and aluminum foil. (We'll also have black paint for the exterior if desired, but no black paint should be used on the interior of the ovens.) Students are welcome to upcycle and bring in any other materials for use in their ovens. They will also submit a labeled design sketch and a written reflection (which will be completed AFTER the demonstration day).
Otherwise, things are progressing swimmingly. We have completed labs on endothermic and exothermic chemical reactions, observed the cooling properties of evaporation by watching a $20 bill extinguish itself when soaked in rubbing alcohol and water, and used the sun's radiant energy through magnifiers to pop some balloons - always a blast, so to speak.
Have a great Labor Day weekend, and we'll look forward to seeing you at Davidson Lake Campus on Tuesday!
