This is a sample of my vocabulary cut-out cards I use, especially with my English Language Learners (ELLs). I use them with all of my students, but I had first started creating vocabulary cards when I realized I needed to do something more for my ELLs. I tried to think of a way to simplify scientific language for all my students. I am a fairly new teacher and this is only a sample, but it is a sample that I had put a lot of time and thought into when I first started teaching. I have tweaked it over time to shorten the definitions even further, with the sole purpose of making it easier to learn science terminology. My students always staple it to their notebooks before we dive into the lesson, so that they can refer to it throughout the chapter.
Hope it helps!
