Science Methods II

 Week 3 Blog  Monday January 21st      In today's class we started off with reviewing last week's lab and lecture. After discussing those topics we started a new topic which is showing patterns of motion by using a graph. We graphed the speed of John and Julie and were looking at the slope of the lines to see who was faster. We have concluded Julie runs faster than John. We were asked why graph motion: Because it represents patterns in motion Show multiple objects on the same graph On a position versus time graph, the slope of the line is SPEED Our next activity in lab is slides! A big question we talked about in lab is what effects a rider speed down a slide? The variables we can test for the speed of a slide is temperature, steepness, kids clothes, material of slide, hight of slide, etc. When modeling the variables we are able to test for is the child's weight, steepness, height, and kids clothes  We built an experiment about if the weight on an object ef...

The big question of the lab is: How to make a race exciting and how do 2 different speeds finish the race at the same time?        In this week's lab we started out by going over the classroom expectations and going through the syllabus. After that talk we started talking about what we did in class. A big topic we talked about are playgrounds and the different types of physics that goes with a play ground. After that we started talking about races and certain questions that goes along with that. We had to model a race in class about how to make it exciting for them to finish the race at the same time. At the end of class we had to race our classmates practicing our models.
