Students raced Hot Wheels and Matchbox cars while recording their times at 1, 2, and 3 meters so they could calculate the cars' speed and determine which type of toy car is the fastest.
GOLD TAPE QUESTION: The Koenigsegg Agera RS supercar is World’s Fastest Production Car at 277.9 mph. If it could drive at top speed the whole way, how long would it take to drive from Bookcliff Middle School to Broncos Stadium in Denver? (you must show your work or explain how you determined your answer)
Then we rolled a dodgeball, basketball, and bowling ball down the hallway. The balls all traveled 10 meters and we recorded the time that each of them took on their journey. We returned to class and solved for the speed of each of the balls then graphed our results.
Congratulations on overcoming your own inertia and making it back to school for 3rd quarter. In class today we put in our 3rd quarter table of contents pages as well as our force notes page, which is attached below. At the beginning of class students attempted the coin stack challenge. Students put half an index card on top of a stack of 5 pennies, then stacked 5 more pennies on top of the card. By flicking the card, students should be able to remove the card without the pennies falling over. Students then competed to see how many pennies they could stack and still be able to remove the card. We then discussed that this trick works because of inertia, which is the property of matter. The definition of Inertia we will use in this class is "an objects tendency to resist a change in motion."
