At work I get to hang out in two different science classes. In 8th grade we’re working on elements. In some of our activities we use a “bubble sheet” to figure out how many electrons live on each shell of an atom. The handout we have does the job, but I wanted to find a version that might be a little easier to use. No luck. So I took to Illustrator and made my own. Here it is. Take it, use it, love it.
