Students will be able to:
-determine why scientists use a standard measurement system.
-describe density and calculate and compare the densities of various materials using the materials' masses and volumes.
Students completed the following bell ringer:
Alex and Jennifer conducted an experiment to test
reaction times in grabbing a meter stick after it is dropped. They each tested
15 friends. Alex dropped the meter stick for his friends and Jennifer dropped
the meter stick for her friends while the other one timed the reactions.
Jennifer's friends reacted, on average, 0.9 seconds faster than Alex's friends.
Jennifer concluded that her friends were faster. Which of the following should
she do next to check her results?
Some classes reviewed home learning 2. All classes should have been assigned home learning 3, which is to read pages 12-21 in their interactive text and complete all pages. They are to write out the answers for pages 18 (Apply it! #2-3) and page 19 (Challenge) on loose leaf paper to be submitted. While some classes have already submitted their answers, other classes must turn this in the first day class is held next week.
All classes should have viewed the BrainPop movie Measuring Matter. You can view the movie by clicking the following link: BrainPop Measuring Matter. On the list, find the title Measuring Matter, and wait for the video to load, then click watch the movie. See how well you do on the quiz!
By now, all students should have their interactive science notebook completed for notes on Safety and on Mass, Weight, Volume, and Density. Be sure you've drawn something to represent each term, and use color. Make sure your questions and summaries for each topic are complete. Also, be sure you've pasted in the information for pages 1-4 and keep page 1 on your assignments updated.
Some students practiced finding mass using the triple beam balance. Others will learn this skill next week.
There is no home learning this week other than to make sure your notebook is complete, including the cover art.
