Unit 3: In Unit 3 we went over Acceleration! I thought it was kind of cool that the because of the earths gravitational pull objects we drop accelerate at a rate of 10m/s^2. We also got to do super fun experiments like riding the danger board down a hill and having Matt skateboard down it! By reading the other classes blogs i realized that they also enjoyed Unit 3! I would have to say that although this unit was the hardest it was the most fun when it came to experiments! :)
This is Devon conducting the experiment which we based our lab practical on. This is called a picket fence i believe and the instrument basically shows us how fast it accelerates between the stripes. This experiment was easy but the test was kind of difficult. Thank goodness this fun / difficult unit is done!
Unit 2: In Unit 2 we went over graphing lines and how the slopes of these graphs could be changed into different graphs such as. Velocity vs Time and Distance vs Time. This unit was fairly easy and most of the lessons were straight forward. No hidden tricks or anything! :)
Unit 1: In Unit 1 we went over accuracy vs precision and scientific notation.
Accuracy is lets say you have 3 darts. You throw the darts at the bullseye and you hit it! all 3 times but they are spread out throughout the bullseye. This means that you're accurate but not precise.
Precision is lets say you have 3 darts. You throw the darts at the bullseye and you miss! All 3 times but they cluster together around the last ring on the board. You are precise for clustering the darts. But you have terrible accuracy and I wouldn't suggest you become a professional dart thrower.
Scientific notation is just taking big big big numbers and condensing them into an equation. For example 5,000,000 can be simplified to 5.0x10^6. This equation will total to 5,000,000 but it looks nicer and takes up less space. The way to do scientific notation is you just simplify. Move the decimal however many places you want to and count the numbers you took out. The numbers you took out will be whatever power of 10 you will have.

Nice blog, I like how you were very thorough and managed to condense everything down nicely.
ReplyDeleteNice job being clear and concise and summarizing EVERYTHING. I like how you included the opinions of others as well.
ReplyDeletenice post. What a focused kid in the picture. this is a really good compilation of everything we learned. You even remembered the scientific notation.
ReplyDeleteNice summary on all the units we've covered this quarter! I like the picture of you doing the experiment too! Keep up the good work!
