2nd Failed Eco-dome and 3rd eco-dome
<- Picture of the entire 2nd failed eco-dome
<-- Dried soil and dead cricket
Problem with the failed eco-dome:
- It was really dry. When my partner and I touched the soil and plants inside, all of them were really dry. In addition, the dead cricket was also dry as well.
- According to our observation previously, crickets that we kept in our eco-dome tend to prefer moisturizing fruits and vegetables like tomatoes, paprikas, cucumbers and more. However, that food really easily get rotten. Either we should put alternatives and find the best food for the cricket or constantly add fresh food to the eco-dome.
- Plants, which produces oxygen for the cricket in the closed eco-dome, also dry out. My partner and I are thinking of putting small plants or just get rid of the plant.
- Last time I only sprayed about 4-5 sprays of water. So I should definitely put more sprays of water to make our eco-dome more humid and appropriate for the cricket.
- According to research, crickets require fresh water and like to eat raw vegetables. More sprays of water and raw vegetables for the cricket. In addition, rotten food does not really matter because crickets in nature consume rotten food.

|Component||Amount incl Units||Reasoning||Daily Observations|
|Black Soil||5.5 cm||crickets like to hide and 5 cm is enough for them. For the first eco-dome built, we used sand it was really dry. However, black soil was just right for the cricket and the eco-dome.||(2 day)
The appropriate amount of soil is from 3cm to 5cm. It is because crickets tend to prefer going up on the branches instead of walking on the soil.
|crickets||1||Crickets usually eat each other when there is not enough amount of food. In addition, in a closed space the food will easily get rotten.||(2 day)
My cylinder shaped eco-dome is small for more than a cricket to fit in. In addition, based my observation crickets are food lovers. So if I put more than one cricket, I am sure my eco-dome will be filled with food for those crickets.
|Cucumber, tomato, paprika||16.8 g||Based on the preference of the previous dead crickets, they prefer to eat paprika and other moisturized vegetables.||This cricket tends to eat less than the other crickets that I had. In addition, since it is moisturized, it tends to rot a bit faster.|
|Water||7 sprays of water||Crickets cannot live in either really humid or dry places.||Using water spray, 6 sprays of water is enough because it provides enough condensations and water for the cricket to live.|
|Plants||2||When the female crickets are pregnant, they lay their eggs on the stem of the plant. In addition, the plants get damages so we need few extras. It provides oxygen for the cricket to breathe in.||Plants are not growing freshly inside the closed space. In addition, the plants that I picked up are not fresh and easily bend. So this time, I used shorter plants so that it does not reach the top of the eco-dome and bend over.|
|log||14cm||During the previous rebuild, the cricket loved going up on the log.||For the whole class time on Wednesday, December 6th, the cricket stayed on the log. We used shorter log this time because since it is shorter, it provides enough space in the upper eco-dome and if cricket falls down, it will not damage the cricket badly.|
|Moss||7.7||Our cricket did not really go down to the soil but just stay in the log. For in case, my partner and I put a piece of land of moss so cricket can rest there. In addition, according to day 1 carbon cycle, moss takes in the carbon dioxide. Moreover, according to research, it gets rid of pollution and conserves water.||Even though the cricket did not rest on the piece of moss, it is definetly better than the standing plants because it does not dry out or die easily.|
Crickets love to stay on the log because, for about 2 hours in a row, my cricket stayed on the log and did not go down to the bottom. Crickets gain extra moisturize by consuming moisturizing vegetables, however, the vegetables easily get rotten so I need to put a vegetable in different places or put other types of vegetable. However, according to the research, rotten food does not really matter to the crickets because, in nature, they consume rotten food. After 4 days, the cricket died. My partner and I assume the death due to the lack of moisture. Even though there were water drops on the wall of the eco-dome, still there was not enough fresh water for the cricket to drink.
Reflection and research:
The death of the cricket was probably due to the lack of fresh water. So for the next eco-dome, I should put a small bowl of fresh water. But not a full bowl of water because cricket might drown in there. Plants do not really help with the eco-dome because it bends over and reaches the ceiling. Also, according to our day 1 carbon cycle, when plants die, they produce carbon dioxide, which we don't need at all. So a piece of land full of moss is the best alternative. Based on my research, there are numerous benefits of having moss or growing moss. It conserves water and somewhat gets rid of carbon dioxide. So it was a great idea to put the moss in!
We changed the long log into the smaller one so that when the cricket falls down on the log, it will not cause a huge damage to the cricket. The original log was about 19cm long but now it is about 14cm. Also, we sprayed numerous times of water so that the eco-dome is more moisturized. We added 2 more times spray of water. We added 7.7g of a piece of moss land because it does not dry out and die, unlike the plants.
