Students will engage in a long term lab investigating biotic and abiotic influences on an ecosystem.
Notes to Teacher: A warm temperature is key to having the shrimp hatch quickly. Place all mini ecosystems under some sort of heat lamp to ensure hatching. For the short duration of this experiment the brine shrimp actually dont need an outside food source, they will feed on their molted exoskeletons or fecal matter. If you are unfamiliar with the GSL, you may want to look at www.usgs.gov for some background information. Just search under Great Salt Lake.
An understanding of the Great Salt Lake ecosystem and also interactions within ecosystems. They should be able to draw a food web of the GSL. Students should also know how to use a microscope and estimate microscopic lengths (to estimate the size of their shrimp and track growth). Students should also understand population survey techniques to estimate the size of their brine shrimp populations. Students should also understand the terms bias, biotic, and abiotic.
Use rubric attached.
Answers: All answers will differ. You should grade based on completion, thoughtfulness and understanding.
