I have done a science project testing how acidity affects the reproduction rate of brine shrimp. I have tabulated my results, but have come across strange data. The weights of the water + brine shrimp have fluctuated and i can't figure out why. How does it fall, because even if they die, they will weigh the same as when the were alive. The water has not evaporated either. Please can someone help? Thanks P.S. I've attached a picture of my table
