I combat “cheating” by launching the marble early by not giving them the angle the final trial will take place at until the end. Students can use whatever tools needed to figure this out, but they can not launch the marble during the procedure phase. Where will the marble land? A marble is shot out of a marble launcher, and students must place a cup so that the marble lands in it on the first try.So, now that you know a little bit about the types of labs, let’s look at how you can use structured inquiry labs to prepare students for the experimental design FRQ. 5 guided inquiry labs you can do next school year to prepare for the experimental design FRQ I think that open inquiry is a great end-of-year review tool, but I don’t really use open inquiry for labs during the school year. Students come up with the question, in addition to the procedure. Open inquiry takes the student generated process a bit further. I will share some of my own examples below. However, this is a great tool to use during each unit. Of course, every lab can’t be guided inquiry. Through doing guided inquiry labs, students become used to figuring out their own procedure. This format most closely matches the types of questions students see on the experimental design FRQ. Assume a negligible effect of friction and air resistance.I bought these poppers from Oriental Trading for a guided inquiry lab on energy! Use the above principles of vector resolution to determine the net force and acceleration of the roller coaster cars. The two diagrams below depict the free-body diagram for a 1000-kg roller coaster on the first drop of two different roller coaster rides. The forces directed perpendicular to the incline balance the forces directed parallel to the incline do not balance. The net force is the vector sum of all the forces. The force of friction can be determined from the value of the normal force and the coefficient of friction F frict is 255 N (F frict = “mu”*F norm= 0.3 Now the normal force can be determined to be 849 N ( it must balance the perpendicular component of the weight vector).
