3 Good Analogy
The part of the tutorial that I thought was most helpful was the analogy of atoms to mattress springs. Teaching Newton’s Third Law, I think students would question how objects such as a floor or table could “push back” when they aren’t living things. They do understand that objects and matter are made up of atoms, so being able to compare atoms inside of an object pushing to springs inside of a mattress pushing will be helpful. Many times you can feel or see the springs moving inside of a mattress, but there are firm mattresses where you don’t feel any movement; however, everyone still knows that there are springs inside. That is how I will try to explain how inanimate objects push back against objects. I am still confused with the concept of different forces acting on each other, which will cause acceleration (the donkey pulling the cart analogy).

4 Acceleration and Force
The tutorial for Newton’s Second Law, especially the diagrams, were very helpful. This law is much easier for me to comprehend. The math equations are still difficult, however, the concepts are easy to come across in real life. After watching the tutorial, I feel more comfortable teaching this material to my students because I am confident that I understand it myself. The activity that I would use to teach mass and acceleration to my students is the rocket balloon. We did this activity during the PISA Institute and it was also in the tutorial. During the summer, my group tried several different options, but when we had two balloons with a little amount of tape, our rocket accelerated the quickest. Now I realize it was because there was more force with two balloons than with one and there was very little mass slowing it down.
