What is the IV?
If water from a river is sampled upstream and downstream from the sewage treatment plant, then the level of toxins will be higher in the downstream sample.
IV: Upstream/Downstream
200
The speed of an object and the direction of its motion.
Velocity
200
The formula for speed.
s=d/t
200
What is the velocity of a car that traveled total of 75 km north in 1.5 hours?

300
List three criteria of a graph.
What section of the scientific method does this go?
Title; X and Y axis; Key: Even Scaled
Data Analysis

Create a Hypothesis:
IV: Amount of Water
DV: Rate of photosynthesis
If there is an increase/decrease in the amount of water given to a plant, then the rate of photosynthesis will increase/decrease.
300
Distance AND direction of an object's change in position.
Displacement
300
What is the difference between speed and velocity?
Velocity incorporates direction!

Rebecca wants to see if her kitten prefers new chicken flavored treats over her usual beef flavored treats. She puts 10 chicken treats in one bowl and 10 beef flavored treats in another bowl. She sees which treats her kitten eats first and repeats this experiment for 3 days.
DV: Treat kitten eats first
IV: Flavor of Treat
500
The speed at any given point.
