Class Discussion Should data be similar? Why or why not? Data should be similar if we want our results validated. What were some essential components of the procedure? Clear steps on how to build the ramp Direction on where to place the tennis ball How to measure the tennis ball’s distance or speed Where to start measuring from When to stop the timer What units to use when measuring Something that is NOT necessary would be a step stating to “Gather your materials”. This is already implied by providing the materials list.
