While you’re looking at the brake pads, alvideo you’ll be able to see how the teacher walked through the process from beginning to end and then she keeps asking that if it didn’t work what do you need to do so if you probably heard that they said the word improve so they need to improve the design and they will test it out again and make adjustments either through the material or the way it’s being stuck together or the whole structure it is or whatever the case is and then they’ll keep on proving until they get it done so this is for the elementary state for the middle schoolers it was a little bit more sophisticated so they had to frame the problem investigate what is the option that they have brainstorm some ideas to solve the problem come up with
