In this Science Buddies project, you'll use a live specimen to investigate how a specific freshwater organism, Daphnia magna, responds to the exposure to different concentrations of nanosilver. You can customize your materials to include the live samples, magnifier, pond water, and other supplies needed to complete this experiment.

Do you know why enzymes are oftentimes called the workhorses of biochemistry? It's because they can speed up a wide variety of chemical reactions, and chemists and biologists use enzymes to do all kinds of jobs. In this project, pectinase, an enzyme frequently used in the food industry, will be used to extract juice from apples.

Rated 5 out of 5 by from Daphnia are great against pond algae Water is crystal clear, unlike the years when we skipped the daphnia. Unfortunately fish love them so much you can't really keep them in a pond with fish.

Rated 5 out of 5 by from So healthy! I bought the culture about two months ago and had to breed them to use for an experiment. They were so healthy I had a tank full in a matter of days. Will definitely order from again in the future.

Rated 5 out of 5 by from Great for Daphnia Magna My son's science experiment left a jar full of daphnia magna survivors which we did not have the heart to kill, so we started feeding them yeast and they are thriving... The pond water we ordered seems perfect for them.

Rated 1 out of 5 by from I recieved a culture and most of the culture turned into cyclops....i feed them algae, yeast, and grain....the whole culture pretty much died as cyclops took over i don't know if they out competed or if they ate the daphnia babies

Rated 5 out of 5 by from Daphnia Cultures Living. We were purchasing the cultures for past few years for studying effects of various agents on Daphina heart rate. The cultures were shipped on time and arrived in satisfactory condition. Once there was an issue with the shipment and when we communicated to the customer service, they were courteous and very prompt in rectifying it. We were shipped us a replacement free of charge. We were very happy about the service provided to us.
