Daphnia are sensitive to light and heat. Work quickly and return them to their home as quickly as possible.
Some changes to the procedure:
We are going to plan on testing 2 daphnia instead of 3. Complete 2 trials with each daphnia (instead of 3).
Moreso than usual, any kind of horseplay or off-task behavior could risk spilling daphnia, breaking equipment, or delaying the experiment (causing daphnia to be out of their home for too long). These behaviors will not be tolerated.
What's the plan?
Today your goal should be to complete your data table.
Tomorrow, you will have the class period to finish your scientific diagram, conclusion, and any pieces of the previous (yeast) lab that you didn't get to.
Next week, we will start Unit 5!

No homework!
Debrief
I can explain how the circulatory system of daphnia is affected by consuming sugar.
