Question

1. problem: does the color of light affect the growth rate of a plant? experiment: grow multiple plants under different color lights (white light, red light, green light, and purple light) and measure their rate of growth. part of experiment answer independent variable dependent variable constants experimental groups control group

Explanation:

• Independent Variable: The factor that is changed or manipulated. Here, it's the color of light.
• Dependent Variable: The factor that is measured and is affected by the independent variable. So, it's the growth rate of the plant.
• Constants: Factors that are kept the same throughout the experiment like type of plant, soil, amount of water, etc.
• Experimental Groups: Plants exposed to different color lights (white, red, green, purple).
• Control Group: A group for comparison, could be plants exposed to natural sunlight or no - light (if applicable in a well - defined way).

Answer:

• Independent Variable: Color of light
• Dependent Variable: Growth rate of the plant
• Constants: Type of plant, soil type, amount of water, temperature, etc.
• Experimental Groups: Plants under white light, plants under red light, plants under green light, plants under purple light
• Control Group: Plants under natural sunlight (or a well - defined non - colored light condition for comparison)
