I have found a Bill Nye video on YouTube that explains what exactly a force is. This is an appropriate video for 5th graders who are learning about motion, measurement, and technological design. This video is really straight forward, and repeats what a force is in different ways. I personally think Bill Nye videos are great to incorporate into classroom learning because, they are quick, easy to understand, and get straight to the point. Plus he does add a silly effect to the videos, which makes it super kid friendly to the children in your classroom. I have attached the video below!
