Now that the water fleas have had the opportunity to produce several broods of neonates we are beginning the selection process of neonates that will be used in the toxicity study. We took the neonates from the 4th brood and randomly selected 40. Those that we selected from came from moms who had shown high The neonates that were selected were then transferred to individual cups and will be allowed to develop and then reproduction rates.
I am thinking of several ways to apply in the classroom. Basically I can incorporate the techniques used in this study into many other kinds of toxicity studies. I was thinking of creating a lab in which the students will look at the effects of pH on the mortality of Daphnia.
