UV Radiation on Organisms

This project is significant because it could help bring about a better understanding of, how UV wave lengths affect the people and the hole in the ozone layer. By determining the effects of UV on Artemia Salina we come closer to alleviating the effects of UV radiation on organisms. In the future this could lead to better UV protection technology. IV: UV exposure in seconds DV: Mortality Rate DV2: Growth Rate it mm/day H1=the UV radiation will kill more Shrimp the longer they are exposed to it. H2=the Artemia are more likely to form defects and some form of stunted growth. N1= The UV will have no effect and there will be no deformities or conditions of any kind on the Artemia Artemia are small crustaceans that live in saline, in-land shores including species like crayfish and brine shrimp. These invertebrates are small, and are generally hard to see in the water, have hard exoskeletons, and little legs that are really hard to see. Males give birth to young through laying cysts, while females produce offspring via live birth, being around since the Triassic period, Pre-historic fish have been sometimes eating Artemia and other times getting picked off by hovering birds. Artemia Salina or Sea Monkeys only go into near shore waters because most salt is far from shore and Artemia can only survive in certain salinity levels making it a little harder to culture in salt tanks. But when saline levels are just right they give peak results in experiments. They have almost no defenses but multiply quickly and are fast swimmers. Artemia also are extremely common in marine shops being used for human or fish food and also for a variety of science projects and has a hefty sale rate, even for how sometimes expensive th... ... middle of paper ... ...now that they’ve hatched, the shells can’t protect them from the UV.) 5. Re-Count the larvae Re-count the larvae exactly the same way as before. The larvae after radiation should have had some form of effect from the UV such as low mean amount, dead larvae, etc… (Note: If you want to re-count again, because you didn’t see an effect, it would be recommended because the UV radiation doesn’t always have instantaneous effects.) Materials List (In order of use) 1 bottle Artemia Salina eggs 4 culture dishes 1 UV lamp 4 500mL. Beakers 4 Air stones/ air pumps 4 Petri dishes 1 Pipette 1 magnifying glass 1 stirring rod Data Analysis Procedure 1. Make a graph representing the number of artemia per .5mL drop when counting artemia. 2. After counting, compare the averages of past countings to the current to find a possible mortality rate.
