Match each term to its meaning
Draw a line connecting each term on the left to its correct meaning on the right. Or write the matching letter next to each term.
| Term | Your answer | Meaning |
|---|---|---|
| Independent variable | A. The thing you measure or observe as a result | |
| Dependent variable | B. Measuring the same thing again and again at regular moments | |
| Controlled variable | C. The one thing you deliberately change | |
| Series of observations | D. Something you keep the same so the test is fair | |
| Trend | E. A short sentence that answers the question using the data | |
| Conclusion | F. The overall pattern, the direction the graph line heads |
True or False? Fix the false ones
Circle T or F for each statement. If the statement is false, rewrite it correctly on the line below.
The independent variable is the one thing you deliberately change in an investigation.
Correct it:
To make a test fair, you should change several things at the same time.
Correct it:
On a line graph, the dependent variable goes up the vertical axis along the side.
Correct it:
A conclusion is just a guess made before you collect any data.
Correct it:
Read the results table
A class measured a seedling's height every 2 days. Use the table to answer the questions below it.
| Day | Height (cm) |
|---|---|
| 0 | 2 |
| 2 | 4 |
| 4 | 7 |
| 6 | 9 |
| 8 | 12 |
| 10 | 14 |
(a) How tall was the seedling on day 4? Write the number and the unit.
(b) Is the trend increasing, decreasing, or staying the same?
1. In your own words, explain the difference between the independent variable and the dependent variable.
2. Why is it useful to measure something many times over a period of days instead of measuring it only once?
