Your teacher asks you to design an experiment that shows how plants respond to changes in their environment. You have two identi

cal plants to do your experiment, and you may add any other equipment of your choosing. Using the scientific method, design an experiment that meets your teacher’s criteria.
Match each step of the scientific method with a step of the experiment.

A. Make observations.

2. Ask a question.

3. Test the hypothesis.

4. Analyze the results, and make a conclusion.

5. Test or modify.

A. Put one plant under a white lightbulb, and
place the other plant under a red lightbulb.
Measure the growth of the two plants.

B. If you observe no change, repeat the experiment with different colors of lightbulbs. If there is a change, repeat the experiment for one or two more trials to ensure that the color of the lightbulb contributes to the change.


C. Do plants grow as well under a different
color of light?


D. Determine whether the plant grown under the white lightbulb or the plant grown under the red lightbulb grew better.


E. Plants grow well under sunlight or a lightbulb
with a hot, white light.

Answer:

1.  Make observations.

Determine whether the plant grown under the white light bulb or the plant grown under the red light bulb grew better.

Observations are anything we notice which lead to a question in our mind.

2. Ask a question.

Do plants grow as well under a different color of light?

As this is a question being asked, hence it will be the question for the scientific method of research.

3. Test the hypothesis.

Put one plant under a white light bulb, and  place the other plant under a red light bulb.  Measure the growth of the two plants.

To test the hypothesis, experiments are performed. This is the experiment.

4. Analyze the results, and make a conclusion.

Plants grow well under sunlight or a light bulb  with a hot, white light.

After the experiments, the results are compiled and a conclusion is drawn.

5. Test or modify.

If you observe no change, repeat the experiment with different colors of light bulbs. If there is a change, repeat the experiment for one or two more trials to ensure that the color of the light bulb contributes to the change.

If our hypothesis does not come out to be true, then another hypothesis can be generated and tests be done for it.

The volume of 7.91 M HCl needed to make 196.1 mL of 2.13 M HCl is ____.
Alona [7]

Answer:

a. 52.8

Explanation:

To find the number of moles of HCl we use the relation M₁V₁=M₂V₂

where M₁ is the initial molarity, M₂ the new molarity, V₁ the initial volume used, and V₂ the final volume obtained.

M₁=7.91 M

M₂=2.13 M

V₁=?

V₂=196.1 mL

Replacing these values in the relationship.

M₁V₁=M₂V₂

7.91 M× V₁=2.13 M×196.1 mL

V₁=(2.13 M×196.1 mL)/7.91 M

=52.8 mL
