Scientific Method
First step in science method
Ask a question or identify a problem.
Variable that is changed on purpose
Independent
A testable explanation for an observation is called
Hypothesis
The variable that goes on the x-axis of a graph
Independent
Steal 100 points from someone
ok
After forming a hypothesis, this step involves checking if its correct but doing something
experiment
Variable that is measured
If sunlight increases, then plant growth will also increase." Identify the independent variable.
Sunlight
The variable that goes on the y-axis of a graph
Dependent
What word is right when pronounced wrong, but is wrong when pronounced right?
Wrong
This step involves looking at information gathered after the experiment
Analyzing data
Variables that are kept the same throughout the whole experiment
Constants/controlled variables
A good hypothesis must be...
Testable
A graph best used for showing percentages or parts of a whole
Pie
What are the colors of the rainbow?
ROYGBIV
red, orange, yellow, green, blue, indigo, violet
How can an observation be made?
Sight, Smell, Taste, Hear, Touch
In an experiment testing fertilizer on plant growth, identify the dependent variable.
Plant growth/height
Predict what happens if a student increases the amount of water given to plants.
Plant growth will increase
The type of graph best for showing change over time
Line
Why is it important to only test one independent variable at a time?
So you can see if that's the one affecting your group.
The last step of the science method
Drawing a conclusion
Why is it important to have n experiment with no independent variable changed
to use as a comparison
Why is a hypothesis called an "educated guess"?
You have to perform research first
Graph that shows comparison of different items
Bar Graph
A teacher tests if different colored lights affect plant growth. Write a full hypothesis for this experiment
If plants are grown under different colored lights, then the plants will grow to different heights
