We all have testing to do and during testing, I still wanted my students to have a chance to stay engaged and working. During our simple machines unit I included an investigation station. I found some awesome simple machine passages from TPT as well and then created this paper as guiding questions. You could also print this into a packet for your students and have them use kiddle.co which we also had as an option ...Google created search engine for kids.
This document has 3 pages : One page for Screw, one for wedge, and one for inclined planes for students to investigate on.
