Can You Spot the Scientific Method?

**Directions:** Each sentence below describes a step of the scientific method. Match each sentence with a step of the scientific method listed below.

A. Recognize a problem
B. Form a hypothesis
C. Test the hypothesis with an experiment
D. Draw conclusions

1. Stephen predicted that seeds would start to grow faster if an electric current traveled through the soil in which they were planted.
2. Susan said, "If I fertilize my geranium plants, they will blossom."
3. Jonathan's data showed that household cockroaches moved away from raw cucumber slices.
4. Rene grew bacteria from the mouth on special plates in the laboratory. She placed drops of different mouthwashes on bacteria on each plate.
5. Kathy used a survey to determine how many of her classmates were left-handed and how many were right-handed.
6. Dana wanted to know how synthetic fibers were different from natural fibers.
7. Jose saw bats catching insects after dark. He asked, "How do bats find insects in the dark?"
8. Justin wondered if dyes could be taken out of plant leaves, flowers, and stems.
9. Arjulia soaked six different kinds of seeds in water for 24 hours. Then she planted the seeds in soil at a depth of 1 cm. She used the same amount of water, light, and heat for each kind of seed.
10. Bob read about growing plants in water. He wanted to know how plants could grow without soil.
11. Kevin said, "If I grow five seedlings in red light, I think the plants will grow faster than the five plants grown in white light."
12. Angela's experiment proved that earthworms move away from light.
13. Scott said, "If acid rain affects plants in a particular lake, it might affect small animals, such as crayfish, that live in the same water."
14. Michael fed different diets to three groups of guinea pigs. His experiment showed that guinea pigs need vitamin C and protein in their diets.
15. Kim's experiment showed that chicken egg shells were stronger when she gave the hens feed to which extra calcium had been added.

Answer :

Final answer:

The scientific method consists of recognizing a problem, forming a hypothesis, testing it through experimentation, and drawing conclusions. Each statement in the question can be matched to a specific step of this method. This structured approach is fundamental in scientific research.


Explanation:

Understanding the Scientific Method

The scientific method is a structured approach used by scientists to conduct research and experiments. It consists of several key steps:

  1. A: Recognize a problem
  2. B: Form a hypothesis
  3. C: Test the hypothesis with an experiment
  4. D: Draw conclusions
