Question

You hear about a new amazing fertilizer called SuperGro. The company selling it claims that using this fertilizer will double your tomato harvest! Sounds great but as a skeptical consumer you ask for a sample so that you can conduct an experiment in your garden before you buy a big bag of his fertilizer.

state a good hypothesis for your fertilizer experiment describe the experiment you would conduct .identify the control and experimental groups/treatments . identify the dependent and independent variables
• name two control variables
•make up hypothetical results
• state a conclusion

Answer 1

Hypothesis: If I use SuperGro fertilizer on my tomato plants, then the harvest will be greater than if I do not use the fertilizer.

Experiment: I would divide my tomato plants into two groups. The first group would be the control group and receive no fertilizer. The second group would be the experimental group and receive SuperGro fertilizer. I would use the same type and number of tomato plants in both groups and plant them in the same location with the same amount of sunlight and water.

Control group: Tomato plants that receive no fertilizer

Experimental group: Tomato plants that receive SuperGro fertilizer

Independent variable: SuperGro fertilizer

Dependent variable: Tomato harvest

Control variables: type and number of tomato plants, location, amount of sunlight and water

Hypothetical results: The tomato plants in the experimental group that received SuperGro fertilizer produced double the amount of tomatoes compared to the tomato plants in the control group that did not receive fertilizer.

Conclusion: Based on the results of the experiment, it can be concluded that SuperGro fertilizer does have a significant effect on increasing tomato harvest. Therefore, using SuperGro fertilizer can be recommended for individuals who want to increase their tomato harvest.
