Today we got ready for the quiz on Unit 2 Section 1. We reviewed and took a practice quiz to do this. We also finished the graph for the coffee filter lab.The graph was a drop height vs. average velocity. After entering our data we saw how the line tapered off at the top. We were then able to estimate the approximate terminal velocity of the coffee filter. I really liked finally finishing the graph so I could find the terminal velocity of the filter. The terminal velocity of the filter was around 0.85 m/s.

Today we took our Unit 2 Section 1 quiz. The quiz was about Gravity, projectile motion, free fall, and terminal velocity. Most of the quiz was multiple choice or match the answers so it did not take very long. I think I did pretty decent on my quiz and I cannot wait to find out what grade I received. The test was short so I was able to start on my homework.

We started unit 1 section 2, but we only skimmed the section.We also played Angry Birds!!!!! Mrs. Giacomelli made a big tower of boxes and she put little green balloons in them. The Balloons had Angry Bird pig faces on them. She also made a slingshot out of elastic cords and fabric that we put little red foam balls into to knock over the tower. We divided ourselves into teams and we shot at the tower. We hit the tower 3 times and we knocked it over once. One of the pigs was orange because another one popped. We called that one the sunburned pig and we put him on the top of the tower.We did this in celebration of the end of the projectile motion unit.

Today we started the Circular Motion lab. We cut some rope and tried to make it just over 1 meter long.We then tied one hexagonal nut on the end of the string hoping it would be 100 centimeters. The string was only about 92 centimeters, though. We then picked Evan who was in my group to swing the rope. Once he swung the rope at a constant rate we timed the time he took to make 20 rotations. We also collected data with more hexagonal nuts as we went to see what happens when you add more mass to something in circular motion.

Today we only watched Bill Nye the Science Guy as he blows up foam Sharks with dynamite. :P
Summary: Today was a very productive week. I learned a lot. I still need to work on completing things efficiently.
