London Harris Purpose The world needs to support the growth of brine shrimp.
Brine Shrimp are important to the environment because
they clean lakes, and feed birds. Therefore, we want to
investigate under which conditions their eggs will hatch
the best. How does heat affect the number of brine shrimp that will hatch? Question Research My hypothesis is that less eggs will hatch in hot temperature than in room temperature. Hypothesis My materials are:1)Brine shrimp eggs 2)Sea Salt 3)Distilled Water 4)Plastic cups 5)Microscope 6)Beaker 7)Pipette (Dropper) 8)Petri Dish 9)Graduated Cylinder 10)Electronic balance 11)Heating pad Materials My procedures are:1)Prepare brine shrimp solution by mixing one gram of sea salt with one hundred mL of distilled water. MIX THESE IN A LARGE BEAKER USING SPOON. Procedures Independent Variable-the heat
Dependent Variable-the eggs that hatch
Control-what doesn't hatch Variables Graph Conclusion My hypothesis was that less brine shrimp eggs will hatch in a hot temperature than in a room temperature. My hypothesis was correct. I was correct because I have a chart that is for the hot temperature and room temperature. The hot temperature has less eggs hatched than the room temperature. The experiment is important because it would be difficult for us to clean the lakes and feed the migratory birds by ourselves. This experiment can be improved by doing the experiment over again. What I have learned from this experiment is that hot temperature hatched less eggs than the room temperature. Observations Although, the brine shrimp are half a centimeter, they can reproduce prolifically. In a cold environment the females reproduce. The brine shrimp reproduce sexually. They reproduce in cold weather and need optimal conditions. They have 14-17 stages for their life cycle. The name of the newly hatched is called Nauplii. It takes brine shrimp up to 3-6 weeks to make them mature. The brine shrimp reproduces from May to December.
Therefore, brine shrimp aren't only important to the enviroment they feed migratory birds. Brine shrimp are important to the enviroment by cleaning up lakes by ridding the waters contaminations such as phosphorous, nitrogen, and other household waste products. The brine shrimp are very important organisms in the Great Salt Lake ecosystem. Without them, all of the birds that use the Great Salt Lake would have to stop along their migratory path and have no energy.
What I have learned about brine shrimp is that they are very important to the enviroment and birds. They can clean lakes and get fed to birds. What I have learned from this experiment is that they are important to the world,science, and for us help us live. But they can only live in very salted water like in the Great Salt Lake, the Mono Lake in California, and in England.
