anne.antoinette Posted December 12, 2011 Report Share Posted December 12, 2011 Hey! We have a tank full of Daphnia in school, any good lab ideas I could do? Reply Link to post Share on other sites More sharing options...
Aimv Posted January 2, 2012 Report Share Posted January 2, 2012 You can do a lab regarding daphnia and caffeine. Count the normal heart rate of one daphnia, then add some sort of caffeine substance then count the heart rate afterwards. It's worked for me.

Stereoisomer Posted January 7, 2012 Report Share Posted January 7, 2012 ^ Caffeine works! Other easily accessible drugs like ethanol (to simulate alcohol) may also do the trick. You may also want to consider acetylcholine/noradrenaline. Ask your lab technicians to see if they stock them. Reply Link to post Share on other sites More sharing options...
