HELP Scientific Method

Question

Use a scientific method to answer the question "Do GMOs affect human health?"

I am having a hard time what variables should I involve to measure the health of humans and how do I test the hypothesis. I am looking for observation, question, hypothesis, making the prediction (if-then), testing the hypothesis, and analysis. Our professor also asked us to answer what type of data collection should we gather. HELP :(((

my hypothesis: GMOs affect the health of humans. im stuck in this step, please enlighten me.

Answer 1

So your hypothesis is very broad. Remember that one key feature of a hypothesis is it must be testable. So think of some ways you could measure health and changes in health and relate them to GMOs. Your hypothesis doesn't address what ways GMOs would affect human health; these could be negative or positive effects. I'll use a different example and you can try to model your own hypothesis after my example.

Observation: my tomato plant is shorter than my neighbor's tomato plant. We use the same soil. Our plants get the same amount of sun. She uses fertilizer, and I don't.

Question: Why is my tomato plant shorter than my neighbor's tomato plant?

Hypothesis: Tomato plants grow taller when they are given fertilizer.

Prediction: If i use fertilizer on my tomato plant, then it will grow taller.

Experiment: Grow two tomato plants in the same conditions: same amount of water, same amount of sunlight, same soil, same sized pot, etc. Give one tomato plant fertilizer (treatment), and the other tomato receives no fertilizer (control). Measure the plants every week for 10 weeks.

Analysis: Graph the growth of each plant to see the change over time.

Conclusion/Results: The plant that received fertilizer grew taller than the one that did not. Therefore, my hypothesis is supported. Tomato plants grow taller when they are given fertilizer.

So think of your own problem. Here is just an example

Observation: Many foods eaten by Americans contain GMOs. There is a high rate of obesity in the US.

Question: Does eating foods containing GMOs cause people to gain weight?

Hypothesis: ...... (must be testable!)

You give it a try! :)
