Question

a student sets up a light outside at night to see if more moths are attracted to white light, yellow light, or no light.

• what is the independent variable?
• what is the dependent variable?
• what should remain constant?
• how could the experiment be improved for accuracy?

Explanation:

The independent variable is what's changed (light type). Dependent is what's measured (moth count). Constants keep conditions same. Accuracy can be improved with repeats.

Answer:

• Independent variable: Type of light (white, yellow, no light)
• Dependent variable: Number of moths attracted
• Should remain constant: Location, time of night, weather conditions
• Improve accuracy: Repeat the experiment multiple times
