Jody’s roses are not doing so well. She needs to liven them up before the competition in 6 weeks. She thinks they may need fertilizer to help them grow. She asks some local rose experts for their opinion and they suggest three different fertilizers. She sets up her experiment to test the three new fertilizers and leaves one rose bush with no fertilizer. She feeds them each the specified amount and measures them each week. Her data is below.

What is Jody's Control?

• No fertilizer
• Miracle grow
• Rose grow
• Garden grow

Refer to Jody's rose and fertilizer experiment below.

What is the independent variable?

• Sunlight
• Type of Fertilizer
• Height of the plant
• Number of plants
