Measurements Unit Preview
We will now be moving on to our measurements unit. Beginning with reading a ruler, we will learn how to measure in cm and mm. We will then move on to reading triple-beam balances and graduated cylinders.
After this, we will have a fun lab activity called the Metric Olympics! Students will compete in different activities to test their skills and knowledge of the metric system.
After this we will move onto density and precision vs. accuracy.
Then we will have a test on all of the above.
All of this information is crucial to success in the lessons ahead.

Scientific Method, Controls and Variables, & Graphs Quiz
Students will have a quiz on the Friday, September 4th (morning classes and 5/6 A Day) and on September 8th (7/8 B Day)
This will be open notes so you should be ok if you have been good about keeping up with your notebook and notes.
Happy Studying!!!

Notes on Graphs:
There are three types of graphs:
1) Line Graph- shows relationship in which a change in the independent variable (manipulated by the experimenter) changes the dependent variable (what the experimenter is looking for a response from)
Rules:
*the graph scale should be readable and make sense
*the independent variable will always be on the x axis
*units should be consistent
2) Bar Graph- communicates data through counting; think of this as when you would tally scores or votes. (Example in class was we came up with four food choices for lunch...chicken, pizza, sub, chicken, burger. When we counted them up, food choices were on the x-axis and numbers were on the y-axis)
3) Circle Graph- lists part of a whole; percentages (Example was the "day in the life" students broke their day down into different activities such as sleeping, eating, school...etc and had to assign hours to eat activity to add up to 24 hours. Then, each student was required to create a pie chart out of the data they collected.)
