What are three of the five steps of the scientific method?
What is problem, hypothesis, procedure, results, conclusion.
100
What variable goes on the x-axis?
What is the independent variable?
100
Draw a picture to show the difference between distance and displacement.
What is see picture.
100
You start at your house, travel 4 blocks west and 3 blocks north and you are at the store. What is your distance and displacement?
What is distance = 7 blocks; displacement = 5 blocks
100
What is a variable?
What is the part of the experiment that changes?
200
Give an example of a hypothesis.
What is if...then....
200
What variable goes on the y-axis?
What is the dependent variable?
200
When will distance be the same as displacement?
What is when the object travels in a straight line?
200
You are standing on the side of the road and a bus drives by at 25 mph to the east. How are you moving, relative to the bus? (Give speed and direction.)
What is 25 mph west?
200
Give an example of a qualitative observation you can make of an elephant.
What is the elephant is gray? What is the elephant is big?
300
In which step of the scientific method do you accept or reject your hypothesis?
What is conclusion?
300
Draw a picture of a graph with a strong positive correlation.
What is see your picture.
300
Give an example of a scalar quantity and vector quantity.
What is scalar = 45 mph, vector = 45 mph south
300
A car travels 80 m in 5 seconds. What is the car's speed?
What is 16 m/s?
300
Give an example of a quantitative observation that you can make about an elephant.
What is an elephant has four legs? An elephant weighs 3 tons.
400
What is the difference between an independent and dependent variable?
What is independent = what the scientist changes; dependent = what changes because of changes made by the scientist
400
Draw a picture of a scatter plot with a weak negative correlation.
What is see picture.
400
What is the difference between speed and velocity?
What is speed is a scalar quantity (10 m/s) and velocity is a vector quantity (10 m/s north)
400
A car changes from 0m/s to 60 m/s in 30 s. What is the car's acceleration?
What is 2 m/s/s?
400
What is the difference between an observation and an inference?
What is an observation uses your senses. An inference is a conclusion you can make from the observation.
500
Why is it important to have only one independent variable?
What is you will be able to draw a conclusion
500
List three things that a graph should always have.
What is title, labels, all available space if filled, line of best fit.
500
If you are driving a car, give three ways that you can accelerate.
What is speed up, slow down, change direction?
500
A car has a speed of 35 m/s for 8 s. What is the distance the car will travel?
What is 280 m?
500
What is a control and why are they important?
What is a control is the part of the experiment that is not being tested (stays the same throughout). It is important that controls stay the same so that the controls do not affect the outcome of the experiment.
