0. Variability
We start the beginning of this trimester talking about variability. Students need to understand how data can show variability. (It's just "0" here to avoid confusion with Newton's 3 laws.)
:: Important Definitions ::
Variability: How spread out or close together data is.
Mean: Add all of the numbers up, divide by how many numbers there were.
Median: The middle number.
Mode: The most common number.
Range: How spread out the data is: Subtract the smallest data from the largest data.
Outlier: The data that "just doesn't fit in." A data point that is far away from the rest. An outlier might show there is an issue with that data.
Cluster: Two or more data points that are close together.
Gaps: Distance between two data points after putting them in numerical order. (Put the numbers from smallest to lowest and see if there is a great distance between any two of your data points.)

1. Newton's First Law

An object in motion will stay in motion, an object at rest will stay at rest, unless acted upon by an unbalanced force.
Inertia: The tendency for an object to keep doing what it was doing. If it's moving, it wants to keep moving. If it's at rest, it wants to stay at rest.

2. Newton's Second Law

Acceleration depends on the mass of an object and the size of the force.
Force: a push or pull

3. Newton's Third Law
scienceuniverse101
For every action force, there is an equal (in size) and opposite (in direction) reaction force.

4. Gravity
If gravity is the only force acting on an object, objects will fall at the same speed. Gravity pulls objects with more mass with more force than lesser mass objects.
:: Important Definitions ::
Weight: the gravitational pull on an object.
Mass: the amount of matter (stuff) in an object.

5. Speed
The main focus of this part of our unit is on calculating speed as distance divided by time. We put an emphasis on showing them that the speed formula shows them that you can measure how something changed with time. For example, how far you go in a certain amount of time or how many times you can chew gum in a certain amount of time.
