Week 3: Slides and Forces  Big Question: What affects a rider's speed down a slide?  independent variable: steepness or weight  dependent variable: speed Thursday Lecture Edited:      We began lecture by completing a warm up question on the go cart test run. We learned to look at the graph based on where you are at a specific time, the position in relation to time is important. We then went over what we completed in lab, our slide investigations. Rather than describing and predicting motion like we did last week, this week we are going to investigate why and how things move. We graphed a position vs time graph showing acceleration. Acceleration is change in velocity over time. We know that riders accelerate while going down a slide, the higher the slide the more time the rider has to speed up. We looked at a graph of an object going down a slide a long slide. In the beginning of the slope the object moves very little in the first tenths of seconds. The more...

  Week 2: Races  Big Question: How can we support play that is exciting but not dangerous?  How can we make a race exciting between people who run at different speeds? Monday Lab: Thursday Lecture: In this lecture we analyzed the lab that we completed and found the Science and Engineering Practices, Disciplinary Core Ideas, and Cross Cutting Concepts that we used in the labs. For the SEP we collecting data by measuring distance, gathering data on time, and conducting the investigation. The main DCI topics we used were measuring the motion, and predicted from those measurements where the racers would end up. Lastly, we examined the patterns of our races, compared them to the second group by recalculating their meters per second and conducted a second race. We than practiced with two more scenarios using meters, and miles.  Speed = Distance over Time  We want kids to be able to describe and predict motion, identify patterns, collect data about motions, and measure...
