Description
This science fair project was performed to find out the effect of water calcium content, on the hatching of brine shrimp eggs. The science project experiment was done using water with different calcium concentrations of 0.1mg/100ml, 0.2mg/100ml and 0.3mg/100ml.
Instructions preview
1. For this science fair project, the independent variable is the concentration of calcium in the water – no calcium (0mg/100ml), 10mg/100ml, 20mg/100ml or 30mg/100ml. The dependent variable is the number of brine shrimp eggs that successfully hatch. This is determined by inspecting the petri dish under the magnifying glass and counting the number of hatched brine shrimp that hatch, every 12 hours. The constants (control variables) are the size of the petri dish, the salinity of the water and the room temperature. 2. The 4 petri dishes are marked A, B, C, D using a black marker pen. .....
