Question

practice: write a hypothesis for each of the statements and identify the variables, control group, and experimental group.
claim 1: organic foods have lower levels of pesticide residues than conventional crops. (5 pts)
hypothesis: if organic foods have lower , then ____________

independent variable:		control(s):
dependent variable:
experimental group

Explanation:

Hypothesis Completion:

If organic foods have lower levels of pesticide residues, then conventional crops will have higher levels of pesticide residues.

Identifying Components:

• Independent Variable: Type of crop (organic or conventional)
• Dependent Variable: Level of pesticide residues
• Control(s): Factors like type of crop (excluding the organic/conventional distinction for control, e.g., same crop species), growing conditions (soil type, water, sunlight), testing methods to ensure only the crop type (organic vs conventional) affects the pesticide residue level.
• Experimental Group: The group of organic crops (since we are testing the effect of being organic on pesticide residues)
• Control Group: The group of conventional crops (to compare the pesticide residue levels against the organic crops)

Filling the Table:

Component	Details
Dependent Variable	Level of pesticide residues
Control(s)	Same crop species, growing conditions (soil, water, sunlight), testing methods
Experimental Group	Organic crops
Control Group	Conventional crops
