Change in water level: 1 mm lower than last week Algae Growth: none Water Color Change: none Plant growth: grass doesn’t seem to be growing much more Indication of water cycle: there is now condensation in the bottom half of the bottle.

Change in water level: a few millimeters lower Algae growth: None Change in water color: None Plant growth: the grass has grown longer and turned a darker green. Indication of water cycle: lower water level and condensation present.

Change in water level: a few millimeters Algae Growth: None Water Color Changes: None Plant Growth: The grass is more dense and longer than last week’s update. Indication of water cycle: visible water droplets (condensation) in top half of bottle on plastic.

Algae Growth: None Change in water level: lower by a few millimeters. Plant Growth: grass seeds have germinated and sprouted and the grass is growing tall. Water color change: None Indication of water cycle: there is condensation in the top and bottom parts of the bottle.

Note: Skipped a day in hopes of germination of first grass seeds and noticeable change but nothing appears to have changed. Change in water level: Nothing noticeable Algae Growth: None Plant Growth: None Water Color Changes: None Indication of Water Cycle: None

Today my partner and I set up the experiment by constructing a self sustaining ecosystem inside of combined pieces of plastic liter bottles. There is water and gravel at the bottom with a string to carry the water from the bottom up to the soil, which contains seeds for grass. We hope to see ourContinue reading “Day 1”

My Name is Ethan Edwards, I am a junior at Hebron High School. Over the next few months I will be documenting an experiment in which I try to create a self sustaining ecosystem and watch it change over time. “Look deep into nature, and then you will understand everything better” – Albert Einstein
