The Natural Science & Engineering students have been studying how heat energy added or removed from a system affects states of matter. We applied these ideas to learn how to solder. Each student created a ring of wire that included learning how to use wire strippers, create an in-line splice, and soldering that splice together with 99.3% Sn/0.7% Cu rosin core solder. They will use these skills next week when they build an LED flashlight which we will use to model the photoelectric effect.
NS&E is exploring chemistry right now to prepare in building batteries from common parts. This is always a fun build because there are so many unique results with groups and the students enjoy seeing the differences. Every year I go to the bank to get a new batch of pennies to be cleaned using our process.
But this year when I opened the box of pennies from the bank I had a small problem…they were all new and straight from the mint!
Students worked today investigating how to write more sophisticated code by using modules and using example code to design their own. By “breaking” code we’ve been able to analyze what are the essential pieces needed to do tasks like calculating Gravitational Potential Energy or velocity if only energy information is known.
We had a late, but great, start to the year so far. We are finishing up our first unit “Balloon Pop” where students learn to work in teams, analyze data, and discuss the differences between precision and accuracy.
