Questions:   ?answer each question; use full sentences; ask instructor if you need help
1-1: Which rat had the fastest baseline metabolic rate?

1-2: Why did the metabolic rates differ?

Summary:    

In this Activity, I learned/observed that: ? write 1-2 sentences on what you observed by doing this experiment – think “big picture”

Activity 2: Determining the Effect of Thyroxine on Metabolic Rate

Data:    
Fill in Chart 1

Questions:   ?answer each question; use full sentences; ask instructor if you need help
2-1: What was the effect of thyroxine on the normal rat's metabolic rate? How does it compare to the normal rat's baseline metabolic rate?

2-2: Why was this effect seen?

2-3: What was the effect of thyroxine on the thyroidectomized rat's metabolic rate? How does it compare to the thyroidectomized rat's baseline metabolic rate?

2-4: Why was this effect seen?

2-5: What was the effect of thyroxine on the hypophysectomized rat's metabolic rate? How does it compare to the hypophysectomized rat's baseline metabolic rate?

2-6: Why was this effect seen?


Summary:

In this Activity, I learned/observed that: ? write 1-2 sentences on what you observed by doing this experiment – think “big picture”

Activity 3: Determining the Effect of FSH on Metabolic Rate

Data:
Fill in Chart 1

Questions:  ?answer each question; use full sentences; ask instructor if you need help   
3-1: What was the effect of TSH on the normal  rat's metabolic rate? How does it compare to the normal rat's baseline metabolic rate?

3-2: Why was this effect seen?

3-3: What was the effect of TSH on the thyroidectomized rat's metabolic rate? How does it compare to the thyroidectomized rat's baseline metabolic rate?

3-4: Why was this effect seen?

3-5: What was the effect of TSH on the hypophysectomized rat's metabolic rate? How does it compare to the hypophysectomized rat's baseline metabolic rate?

3-6: Why was this effect seen?

Summary:

In this Activity, I learned/observed that: ? write 1-2 sentences on what you observed by doing this experiment – think “big picture”

Activity 4: Determining the Effect of Propylthiouracil on Metabolic Rate

Data:    
Fill in Chart 1

Questions:  ?answer each question; use full sentences; ask instructor if you need help
4-1: What was the effect of propylthiouracil on the normal rat's metabolic rate? How does it compare to the normal rat's baseline metabolic rate?

4-2: Why was this effect seen?

4-3: What was the effect of propylthiouracil on the thyroidectomized rat's metabolic rate? How does it compare to the thyroidectomized rat's baseline metabolic rate?

4-4: Why was this effect seen?

4-5: What was the effect of propylthiouracil on the hypophysectomized rat's metabolic rate? How does it compare to the hypophysectomized rat's baseline metabolic rate?
