Hi Teachers, Students, and Parents, This lesson plan and experiment kit is an empirical method to test if your local body of water will have an algae bloom. It contains a detailed four-page lesson plan with experiment instructions. Also included are liquid nutrients (sodium nitrate, sodium phosphate, and a complete algae nutrient mixture) you need to supply household bleach. The experiment involves collecting water from a pond or lake near you, then dividing it into 5 different treatments. You will use plastic drinking water bottles as your culture flasks. The treatments for this kit are a positive-control (algae culture), negative-control (chlorine bleach), test for nitrogen limitation (sodium nitrate), and test for phosphate limitation (sodium phosphate). The test can be repeated many times to get replication. We include a secchi stick, so that you can quantify the algae growth, using Beer-Lambers law. (You can see a video of the secchi-stick on Algae Research Supply's You Tube channel). Soon you can see a video of this product also.
