Motion and Forces:
Newton's Three Laws apply to everything, for example in our 2nd quarter planetary explorer lab we saw all of theses laws. Newton's first law is an object at rest stays at rest and an object in motion stays in motion until an outside force stops it. We see this when Mr. Casey drops the explorers from the lights, when he releases the explorer he sets it in motion and it stays in motion until it hits the floor, an outside force. Newton's second law, more mass less acceleration, less mass more acceleration, is seen when the explores are racing through the obstacle course, the smaller explorers were able to accelerate faster than the larger explorers. Newton's third law, for every action there is an equal and opposite reaction, is shown when the explorers are charging at each other, when the wheels turn it propels the car forward.
Structure of Matter:
Atoms bond together to make molecules this is called a compound.When a molecule or an atom mixes with another molecule or atom this is called a mixture. The difference between a compound and a mixture is that a mixture can be separated and compounds can't. Subatomic Particles are just particles that are smaller than an atom. Along with the structure of the atom there is also the states of matter. This is whether it is a solid, liquid, or a gas. For example ice is a solid when it is left out it becomes a liquid and when heated it becomes a gas (steam).
Density and Buoyancy:
Density is found by dividing mass by volume. Buoyancy depends on if an object can displace more water then it crashes in on it. Water's density is 1g/ml anything less than that floats anything higher sinks.

Out of these topics I think that motion and forces is the most important because we use this every day to do everything. Walking is a perfect example, to walk we thrust forward, force, and we have made motion, to most reference points. So as you can see force and motion is very important.

The scientific method is the rules of science. Most things can pass through these rules but, science dose have its limits some things like dreams and thoughts can't be tested by the method and therefor are not science. The scientific method is important because it helps us explain the world arounds us, and lets us make things that help us survive, like medicine.

I think that I did very well this year, like I do every year. I am not being self obsessed or conceded I am just telling the truth. I try my hardest in everything I do, that applies to this year. Even if I am not the best at something or it doesn't click right away I don't give up, that is my best, and that is all a teacher asks for. I do think that I have grown, coming into this year I was sacred that I wouldn't be ready for the weight of high school but, now I know I am as prepared as I ever will be. As far as what was hard or easy for me it seemed like in beginning of the year everything was really easy and we spent a lot of time on it and as the year progressed it got a lot harder and we spent less time on it, I think that that was just because I didn't get it right away and by the time I got it we moved on so it seemed faster. I am very interested in oceanography, like space it is a huge mystery yet, unlike space it is so easily accessible. Next year I plan to go into AP physics.
