Do you need a record sheet students can use when designing their own science investigations? Here you go!
I teach 1st/2nd graders, and the investigation record sheets I found were either too complicated, or, like so many premade templates, didn't give my students enough space to write. I solved both of these problems by creating my own. It includes sections for the question, hypothesis, materials, steps, data, and conclusion.
I hope you find it helpful!
