This week in science we read about H (habitat loss) I (invasive species) P (pollution) P (population) O (over consumption) we also briefly visited a bus that ran on sun light and was good for the environment. inside the bus we tested alcohol and accidentally nicotine on a Daphnia which eventually killed it because nicotine slows down the heart rate while alcohol slow it down.
This week in science we learned about H.I.P.P.O and how we use Daphnia to test the effects of drugs on humans and also to test the quality of fresh water. We learned that Daphnia are easy to find, they live in fresh water from puddles left by rain to lakes in the suburbs. We learned that due to each part of H.I.P.P.O has a huge effect on the world around us.
