Bottle Habbitat

At the beginning of the semester each of our lab groups created a bottle habitat out of 2 liters, sponge corks, string, soil, plants and water. Now that the semester is over, I have looked at our habitat and I am pleased to say it is still alive and thriving. From what our professor tells us, so long as it doesn't get opened and none of the seals break, there is no limit of time to how long they can last. This is because it has adapted to its own environment and still gets sunlight. Because the plants inside are still getting sunlight, and will constantly have water, they can still go through photo syntheses which allows them to keep on living. I honestly can say I never though that these would make it to the end of the semester, but I have been proven wrong. I am not only confident that these bottle habitats work, but I also believe that if left how they are, they really will flourish forever. I am so convinced that I really want to use this project in my classrooms when I become a teacher. Below I have pictures of my habitat for you to check out.
