Discuss your investigation about reducing the effect of acidity on seed germination with your classmates. 

1. Describe your design solution and how you conducted your experiment.

2. Was your solution successful? Explain by citing evidence from your experiment. 

3. How could you refine your solution to make it better?

4. How does your design solution compare to the designs of other students?

3.21 Discussion: Factors Affecting Transpiration

In this threaded discussion, you will draw on the data from your lab. You will post answers and comments to the following questions:

1 Describe how you conducted your experiment, and explain how you reached your conclusion.

2 Evaluate your investigation, and describe some ways that you could modify your investigation.

3 Respond to your classmates' experimental designs and conclusions. Do they support their conclusions with evidence?

4 How do the results of these experiments support the claim that feedback mechanisms maintain homeostasis?

Answer these questions in the introduction of your Lab Report:

What is transpiration?

How does water move through a plant?

What was the purpose of your experiment?

Answer these questions in the discussion and conclusion of your Lab Report:

What do your results indicate about the effect of the variable tested on
transpiration? Explain using evidence from your experiment.

How do the results of your experiment support the claim that feedback mechanisms help organisms maintain homeostasis?

How could you modify your investigation?

Suppose you notice that fewer soybean seeds seem to begerminating in one of your fields this year. You also know that youhave been irrigating that field over the past 10 years and thatthere is a possibility that salts from the water are building up inthe soil as the irrigation water evaporates from the surface of thesoil thus perhaps reducing the germination rate of the soybeans

1. Now that you have thought about the above pieces ofexperimental design, go ahead and outline/design an experiment thatthat would investigate this hypothesis.
