Question

1. which variable would be an independent variable? the temperature 11. which variable would be a dependent variable? the number of crickets chirps 12. which variable (#10 or #11) would ideally be plotted on the x - axis of a graph? the location 13. in the collection of data, list at least 3 important constants (also known as “controlled variables”)?

Explanation:

1. The independent variable is the one that is manipulated or changed. Temperature can be controlled and is likely to affect other factors, so it is the independent variable.
2. The dependent variable is the one that is measured and is affected by the independent variable. The number of cricket chirps depends on the temperature, so it is the dependent variable.
3. The independent variable is plotted on the x - axis. Since temperature is the independent variable, it should be plotted on the x - axis.
4. Constants could be factors like the type of crickets, the humidity level, the time of day (assuming the experiment is done at the same time each day), and the location (if it remains the same) as these can affect the results and should be kept the same to isolate the effect of temperature on cricket chirps.

Answer:

1. Temperature
2. The number of cricket chirps
3. Temperature
4. Type of crickets, humidity level, time of day
