After talking about Notebook Expectations, I like to talk about safety. In my classroom, it was highly unlikely that we would use anything that wouldn’t be used in your kitchen, but it’s still a best practice to have this discussion with students. My main point is making sure that students are respectful of themselves, others and our classroom equipment.
To show them how serious I am, I usually have each student sign a safety contract that we then glue into our STEM Notebooks. Having students put their signature on something impresses the importance and make it easier to enforce if students start to get lax as the year goes on.
