Vector
The length between the start and end of a path.
Displacement

(Need both correct)
-Scalar
-Vector
What are the steps of the scientific method?
-Ask a question
-Form a hypothesis.
-Conduct an experiment.
-Analyze results.
-Form a conclusion.

Scalar
-Is distance scalar or vector?
(Need both correct for points)
-Vector
-Scalar
-Speed: 15 feet per minute
-Velocity: 15 feet per minute north
A plant outside my house has grown taller in the same time span than a plant inside my house. I predict that this is because the outdoor plant receives more sunlight. What step of the scientific method did I just do?
Form a hypothesis
What will the next unit be about?
Forces!
37 meters per second north
Vector
Wendy walked 24 meters north, stopped, and walked 21 meters south. What is the distance that she traveled?
45 meters
I ran 31 miles southeast in 4.5 hours. What is my speed? What is my velocity? (Round to the nearest WHOLE number)
-Speed: 7 miles per hour
-Velocity: 7 miles per hour southeast
Define Independent Variable.
Define Dependent Variable.

-Something you control in an experiment.
-Something you do not control and/or that you measure in an experiment.
What is your favorite part about an Aspire day?
Open ended question (but I will not accept the answer of leaving)
the pancake is 56 kilograms.
scalar
Wendy walked 24 meters north, stopped, and walked 21 meters south. What is the displacement?
3 meters north
A marble rolled along the long side of your table in 3 seconds. Measure out the distance that the marble traveled in centimeters. Then, determine the speed of the marble.
-## centimeters per second
I studied the speeds of eighth graders and sixth graders. I predicted that the eighth graders would be faster. After conducting the experiment, it was determined that the average speed of an eighth grader is 6 mph while the average speed of a sixth grader is 5.5 mph.
Do the last step of the scientific method.
You need to form a conclusion.
Conclusion: Eighth graders are on average faster than sixth graders and my hypothesis is correct.
What is something you would like to see more of in future science classes?
Open ended question.
-I drove for 2 hours.
-I walked 5 miles this morning.

I walked the length of 3 square tiles in my classroom. What is that distance in inches?
To be determined...
You casually walked from my desk to the door. That distance is 40 feet. Time how long it takes to do that walk in seconds. Then determine the speed and velocity (use the compass on the board for the direction).
-Speed: ## feet per second
-Velocity: ## feet per second east
I want to study the average speeds of eighth graders versus sixth graders. Give me an example on how to conduct this experiment with as much detail as you can
Example: I will gather 30 eighth graders and 30 sixth graders. One by one, I timed and measured out the speed of each student running a set distance on an outdoor track. I found the average for each grade using math.
Tell me something that you learned about Isaac Newton from that packet in the first week of classes.
