Ecosystem Lab Report By Yazmin Herrera by Yazmin Herrera https://padlet.com/herreray/fcqq3535mtg2 Made with love (: en-us 2017-10-23 13:50:52 UTC 2025-11-15 05:35:09 UTC hello@padlet.com Ammonia herreray https://padlet.com/herreray/fcqq3535mtg2/wish/199581479 It is the amount of waste present in the water. It's important to test for this because it is very common, but it can be toxic to the living organism causing death, growth, and problems reproducing. You have to make sure Ammonia is under 1.5. ]]> 2017-10-23 14:07:35 UTC https://padlet.com/herreray/fcqq3535mtg2/wish/199581479 Nitrate herreray https://padlet.com/herreray/fcqq3535mtg2/wish/199586285 It is not harmful to aquatic organisms or an environmental problem. In fact low nitrate levels help the health of the fish. ]]> 2017-10-23 14:15:13 UTC https://padlet.com/herreray/fcqq3535mtg2/wish/199586285 Dissolved Oxygen herreray https://padlet.com/herreray/fcqq3535mtg2/wish/199590628 It's the amount of oxygen concentration dissolved in oxygen in the water. It is very needed by fish to survive.]]> 2017-10-23 14:21:50 UTC https://padlet.com/herreray/fcqq3535mtg2/wish/199590628 pH herreray https://padlet.com/herreray/fcqq3535mtg2/wish/199592495 pH measures how acidic or basic the water is. It is important to test for the pH weekly, because natural materials can change the water quality. ]]> 2017-10-23 14:24:41 UTC https://padlet.com/herreray/fcqq3535mtg2/wish/199592495 What evidence from your data can show that the nitrogen cycle was present in your ecosystem? herreray https://padlet.com/herreray/fcqq3535mtg2/wish/199598624 The data I collected shows that the nitrogen cycle is happening because having more nitrate than ammonia means that ammonia is converting to nitrite to change to nitrate. ]]> 2017-10-23 14:35:17 UTC https://padlet.com/herreray/fcqq3535mtg2/wish/199598624 What are some changes you observed over all the 7 weeks in your ecosystem? herreray https://padlet.com/herreray/fcqq3535mtg2/wish/199599189 Some of the changes I noticed were that the Dissolved Oxygen kept increasing. Another thing is that the temperature wasn't steady, it would go up one will and down the next week I checked. ]]> 2017-10-23 14:36:17 UTC https://padlet.com/herreray/fcqq3535mtg2/wish/199599189 Did you encounter any problems trying to keep your ecosystem stable? were you able to solve the issue(s)? herreray https://padlet.com/herreray/fcqq3535mtg2/wish/199600034 I had only one problem during the project, and that was when my nitrate was 5ppm and the ammonia was .25. What I did to solve this problem was to do a water change. ]]> 2017-10-23 14:37:40 UTC https://padlet.com/herreray/fcqq3535mtg2/wish/199600034 What was the most difficult part of this PBL assignment? What was the funniest, weirdest, or most interesting that happened during the 7 week period? herreray https://padlet.com/herreray/fcqq3535mtg2/wish/199602030 The most difficult part was making sure my fish Kevin was eating because he wouldn't eat often. An interesting thing that happened was at fist my fish wouldn't swim or be active but a couple weeks later is when he started swimming more, and he wasn't so scared of his surroundings. ]]> 2017-10-23 14:41:01 UTC https://padlet.com/herreray/fcqq3535mtg2/wish/199602030 If you could sum up the entire project into 5 detailed through statements about what you specially learned from this project, what would they be? herreray https://padlet.com/herreray/fcqq3535mtg2/wish/199603307 I've learned taking care of a fish is not as easy as it looks. They require more attention than what we give them. It takes time to check if the water they're in is safe for them to be in. Water is really important for them as it is for us. Plants are important to the aquatic life as it is for us. ]]> 2017-10-23 14:43:24 UTC https://padlet.com/herreray/fcqq3535mtg2/wish/199603307 Suggestions for students next year herreray https://padlet.com/herreray/fcqq3535mtg2/wish/199990606 I suggest they wait the 5 min for the nitrate and ammonia test that way you know the water is good for the fish. Make sure you have a fresh plant because that is what your fish is going to eat. If you have an aquarium it's important to have it fill up almost the way so the fish has more freedom to swim. ]]> 2017-10-24 14:04:31 UTC https://padlet.com/herreray/fcqq3535mtg2/wish/199990606 How did this project help you understand environmental issues that are related to water quality? herreray https://padlet.com/herreray/fcqq3535mtg2/wish/199994540 This helped me understand that we need to be more careful of what we put out in this world because for us to test the water quality in the classroom is easy but we can't be able to go around the world and test all the water quality. This is made me understand we need to be more careful of what we put put in this world because it could be hurting the aquatic life. ]]> 2017-10-24 14:11:51 UTC https://padlet.com/herreray/fcqq3535mtg2/wish/199994540
