Homeostasis & Daphnia

Day 16

Temperature &Metabolic Rate

• Based on what we just discussed, what do you think will happen with the Daphnia's heart rate as temperature increases?

• Come up with a hypothesis for this experiment

• Write it in the if...then... format

• You will have 3 minutes to type it in.

Fill in the Blanks

What is your hypothesis about the relationship between daphnia metabolic activity and temperature?

Observe the Daphnia

10 Degrees

Fill in the Blanks

How many beats per minute did you count for 10 degrees?

Observe the Daphnia

20 Degrees

Fill in the Blanks

How many beats per minute did you count for 20 degrees?

Observe the Daphnia

30 Degrees

Fill in the Blanks

How many beats per minute did you count for 30 degrees?

What is your conclusion?

Did the data support your hypothesis?
