Parts of a Graph
This is the horizontal line on a graph.
x-axis
What is the first step in the scientific method?
Ask a question
**Double**
You measure the temperature outside every hour from 8 AM to 2 PM. Which graph would best show the change in temperature?
line graph
This is an educated guess you make before doing an experiment.
hypothesis
A scientist gives one group of plants fertilizer and another group no fertilizer to see which grows taller. The height of the plant is the ______________________.
Dependent variable
**Double**
This axis is labeled with the dependent variable.
y-axis
**Double**
After asking a question, what should you do to gather information about your topic?
Conduct research
A line graph is used to show _________________.
changes over time
**DOUBLE**
This is the one thing you change in an experiment.
independent variable
A student tests three different brands of paper towels to see which absorbs the most water. The brand of paper towel is this.
independent variable
This tells you what information is being shown on the graph.
The title
After completing an experiment, you should analyze your _____________.
data
You want to compare the heights of five different paper towers. Which graph should you use?
bar graph
These are the things you keep the same in an experiment.
constants
A teacher wants to test if playing music helps students concentrate. All students take the same test at the same time of day. The same test and same time of day are these.
constants
On a graph showing the height of different towers, the x-axis lists Group 1, Group 2, and Group 3. What does the x-axis represent?
Groups being compared
**DOUBLE**
What should you do after analyzing your data to summarize your findings?
Draw a conclusion
A class survey shows that 12 students chose experiments, 8 chose building models, 6 chose outdoor investigations, and 4 chose science videos. What is the total number of students surveyed, and which graph could show how the choices make up the whole class?
30 students and a pie chart?
This is the part of an experiment that stays “normal” so you can compare your results.
control
**DOUBLE**
A researcher tests if saltwater or freshwater freezes faster. What is the independent variable?
type of water
This part of a graph tells you what the numbers on the axis increase by, such as 1, 2, 3 or 10, 20, 30.
Scale
The __________ does not receive the experimental treatment and serves as a comparison.
control or control group
Choosing an appropriate scale:
You are creating a bar graph to show the height of four towers: 20 cm, 40 cm, 60 cm, 80 cm, 140 cm. Which scale would be most appropriate for the y-axis?
The information you collect during an experiment, such as numbers, measurements, or observations.
Data
A student tests if running shoes with extra cushioning help athletes jump higher. One group wears cushioned shoes, and the other group wears regular sneakers. The group with regular sneakers is this.
control
