Today was the first day of OGT's so our class period was moved to after 5th. To start of class we took a cell phone pull (after Mr.E redid the poll because it wasn't working) for "The Swinging Pendulum" worksheet. Next we turned to pg. 161, the pendulum lab, and worked with our lab partner, not our table, to find out what the correct answer was to the worksheet we had for homework. Liz and I found that the string length affected the number of swings, and weight of the bob and the height of the bob did not affect the number of swings. Once the lab was finished we turned in the lab and picked up our homework (vibration wkst) and the vibration packet. Something strange that happened today was that Hunter insisted on having a hug with Coats-Haan and Buck. Then team "I Heart Life" had a very special intimate hug.
QOD- How did you control your variables in your pendulum experiment?
when testing height we made sure we didnt change the length of the sting, and we used the same bob at both heights
when testing which bob would swing more we made sure the height remained the same and the string length for each was the same
when testing the length of the string we made sure to pull it to the same height and used the same bob in both string length tests
