When I was teaching middle school science and covering the 5 states of matter, I decided to create a word wall reference for my students. I added a new word(s) as we went through our unit. It is important to remember that many students are visual learners, and having a reference point with an example can go a long ways in helping our students better understand a scientific concept.
I also printed the word wall posters in half sheets so that students could glue them into their science notebook and have the terms as a study tool. In our lesson, we went over the following 20 words. I have created a printable poster resource you can grab here.
