Individual+topic+investigations

Jarett Jones Individual topic The topic I want to teach is chapter 6 which is forces and motion, the section I want to specify on is newton’s laws of motion. I am really curious to learn about this because I have heard about Sir Isaac Newton before briefly and I want to know what his 3 laws mean scientifically. I want to learn about this a lot because like in any sport you have an unbalanced force then you hit the baseball tennis ball hockey puck golf ball then the object you hit is a object in motion. This really intrigues me, I would also like to learn how momentum effects (if it does) an object and what it will do to the object. I also know this section is kind-of math based with lots of formulas I would like to see how the mathematical formulas transfer into a scientific law. These are the 3 laws that Sir Isaac Newton created 1. Every object in a state of uniform motion tends to stay in that motion unless an external force is applied to it. I would like to know what kind of object that applies to and how it will effect the objects motion. The next law of motion is the relationship between an object's mass //m//, its acceleration a, and the applied force //F// is //F = ma//. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector, this one confuses me a little bit so I would like to know what it means so we can make a real life connection as to where in the real world this might occur. The third and final law of motion is for every action there is a equal and opposite reaction. This is in my opinion the easiest to understand because if you through a ball the ball would be pushed away form you but friction would then cause you to stay still, if you had roller skates on you would roll backwards. Those were the 3 laws of motion created by Sir Isaac Newton this topic will help me to learn about who Sir Isaac Newton was. This is very important to know not only who he is but what he did for the world. I would really like to know more than the little I know already because what he did is so important that I want to know more about him. This is why I would like to teach this chapter and section for our project.

Ethan’s Individual Topic

The topic I choose was chapter 8 earthquakes in our online textbook Earth. I choose this topic because I thought it would be interesting to look at how earthquakes occur more in depth. Like how the tectonic plates shift and release force to make earthquakes. Also we could talk about specific examples of earthquakes in the past years. Like the earthquake in Japan that happened quite recently and the earthquake in Haiti. Another thing we could discuss is how scientists can try to predict when an earthquake will happen and how large the earthquake will be. I think that would be interesting because we could look at the different machines they use and the research they have to do. I know that earthquakes are measured on a scale from 1 to 10 magnitudes but there is no limit of how big an earthquake can be. Like the earthquake in Japan was a magnitude just over 9.0. I also know that there are three main fault types of earthquakes they are normal, thrust, and strike-slip. This is why I think we should do our presentation on earthquakes.
