Question

directions: review the experiment below using the reading protocol and then identify the components of the scientific method by completing the graphic organizer provided. experimental scenario #1 a student investigated the effect of radiation on the germination of bean seeds. he thought that exposure to radiation would limit the seeds ability to germinate (grow) much like ultra - violet light causing skin cancer. three hundred seeds were soaked in distilled water for one hour. they were then divided into three groups. one group was placed in a microwave oven on high for three seconds. another group was microwaved on high for six seconds. the last group was not microwaved. the seeds were then planted in three separate flats and given the same amount of water. the seeds were then planted in three separate flats and given the same amount of water. the flats were placed in a location with a constant temperature of approximately 27 degrees celsius. each day for two weeks the number of seeds that germinated each group was recorded.

Explanation:

Step1: Identify the problem

The student wants to know the effect of radiation on bean - seed germination.

Step2: Formulate a hypothesis

The hypothesis is that exposure to radiation will limit the seeds' ability to germinate, similar to how ultraviolet light causes skin cancer.

Step3: Design the experiment

Three - hundred seeds are soaked, divided into three groups. One group is microwaved for 3 seconds, another for 6 seconds, and the third is a control (not microwaved). All are planted in separate flats, given the same water, and placed in a 27°C environment.

Step4: Conduct the experiment

Plant the seeds and record the number of germinated seeds in each group daily for two weeks.

Step5: Analyze the data

By looking at the daily germination numbers of each group, trends and differences can be identified.

Step6: Draw conclusions

Based on the data analysis, determine if the hypothesis is supported or rejected.

Answer:

The components of the scientific method for this experiment are:
Problem: Effect of radiation on bean - seed germination.
Hypothesis: Radiation exposure limits seed germination.
Experiment design: Seed treatment (microwave times and control), planting conditions.
Experiment conduction: Daily recording of germinated seeds.
Data analysis: Analyzing germination numbers.
Conclusion: Determining if the hypothesis is supported or not.
