Technique or series of steps used to investigate a phenomenon.
Scientific Method
Fill in the blank:
If (1.), then (2.)
If (IV), then (DV).
When an object changes position.
Motion
The distance an object travels per unit of time.
Speed
Ms. Paisley hopped 45 kilometers north. She stops for a banana and then hops 15 kilometers east. What distance did she cover?
60 kilometers
---No unit, no points!
A testable statement that attempts to answer a question.
Hypothesis
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
The speed of an object and the direction of its motion.
Velocity
The formula for speed.
s=d/t
What is the velocity of a car that traveled total of 75 km north in 1.5 hours?
50 km/hr North
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.
Distance AND direction of an object's change in position.
Displacement
What is the difference between speed and velocity?
Velocity incorporates direction!
Bob pogo sticks to his science class. He travels 8 m east the 4 m north. What is his displacement?
8.94 m
List ALL SIX steps of the scientific method in ORDER!
1. Ask a Question
2. Research/Background Information
3. Make a Hypothesis
4. Conduct an Experiment
5. Analyze Data
6. Draw Conclusions/Share
Identify the DV:
A study was done to find if fuel types affect the engine’s performance in a car.
DV: Engine Performance
An indicator that orients you; the place from where you measure, record, or witness an event.
Reference Point
Describe the motion of this graph.
The graph shows a speed that is increasing quickly.
How much time does it take a person to walk 12 km north at a velocity of 6.5 km/hr?
1.8 hrs
Units matter!
The name of the GROUP that is being tested or changed purposefully.
Experimental Group
Identify DV and IV
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
The speed at any given point.
Instantaneous Speed
This mathematical term is the same as speed in a motion graph.
Slope
A whale swims at a constant speed of 8.0 m/s for 17 s. Calculate the distance travelled by the whale.
