Bubble Map for Foreword
Here's the handout to guide students through completing the bubble map for the book Foreword.
1st 9-weeks assignment list
This is the list of assignments students should have completed by Oct 18, which is the end of the 1st 9-weeks. Any assignment not completed by the 18th will become a zero in the gradebook.

Studying for Friday's test
If you've come here to study for the test on Friday, you can find three separate posts that will help you. Scroll down and read the posts:

For the test, you will need to know some basic vocabulary.
independent variable = the variable that is purposely changed by the scientist in order to see if the dependent variable changes with the independent variable; you can also think of this as the difference in your groups.
dependent variable = the variable observed and/or measured during the experiment to find out if it changes with the independent variable
controlled variables = all the things that could change but the scientist keeps the same to prevent them from interfering with the experiment
hypothesis = a prediction of what you will find in your experiment; a predicted answer to your scientific question; a hypothesis is usually stated as an if/then statement.
Important detail: A scientific hypothesis must be testable.
In our class experiment, we had the question, "Do 7th grade DRMS boys have better hand-eye coordination for throwing than 7th grade DRMS girls?"
Our independent variable was the gender of the people--boys vs girls.
Our dependent variable was the number of baskets scored by each person.
Our controlled variables included everyone using the same tennis balls, standing the same distance away, throwing at the same trash can, in the same room, having the same number of tries, etc.
Remember that the independent and dependent variables will be in the hypothesis. The "if" part contains the independent variable, and the "then" part contains the dependent variable. In our experiment, the "if" was comparing boys and girls, and the "then" was the number of baskets scored per person.

Our hypothesis was, "If I compare the accuracy of
7th grade DRMS males and females at throwing tennis balls into a
trash can, then it will be found that males are more accurate than
females."
Our independent variable was the gender of the people--boys vs girls.
Our dependent variable was the number of baskets scored by each person.

Multitasking study guide
For the multitasking information on the test, you will need to know:
Multitasking is the ability to think about two things at once. Obviously, people can do two things at once, such as walking and talking. But, people cannot think about two things at once.
When people think they're multitasking, such as listening in class and drawing, their brain is really switching back and forth.
The brain naturally focuses on social information. So, social cues, such as text messages, are very distracting when you're trying to focus on something else.
