Eco dome design components:
- Amount of soil
We turned our container sideways and pretty much filled ¼ of the container with soil that was provided to us by the teacher.
- Types of soil
We used the soil that was provided for us. The soil was a mixture of clay, which made the soil kind of sticky, and the soil was very organic so there were lots of leaves and branches inside.
- Number of plants
This time, we added only 1 plant because we thought that if we added 2 plants, then there would not be enough co2 for the plants, so it would die. By adding 1 plant, that plant gets all the co2 that it needs instead of having to divide it.
- Types of plants
We went outside to the playground area in the back of the HS gym, and we picked out just small plants that had lots of leaves so it can maybe produce a lot of oxygen and fit inside our eco-dome.
- Number of grasshoppers
This time, we added 1 grasshopper because we thought that maybe 1 would be enough to survive with 1 plant inside the eco-dome and because there were no a lot left, and so we just took 1 grasshopper so that people could also have 1. We did not add any other types of animals because we thought that they would not be useful to us.
Changes made on design day:
- We changed a lot of things while rebuilding our eco-dome the 3rd time. The first thing that we changed was that we used a grasshopper instead of a cricket this time to try and change things. We also turned our container sideways so there would be more space for the grasshopper to move around. The downside of this was that we had to find smaller plants to use to it could fit. Another thing we did was that we tried to put the eco-dome outside in the sun to see what would happen, we did because we thought that the plants would have more sunlight. The last thing that we did was that we added a bottle cap of water inside the eco-dome just in case there was no water, and the plant would die.
Observations of ecodome:
- The grasshopper unfortunately died, we think that it died because the outside was too hot, and so the grasshopper could not stand it, and it pretty much died out.
- In the picture you can see the side of our eco dome it is very blurry whole inside of our eco dome was very damp, there were lots of water dripping out from the soil. We are not really sure why this happened.
- As you can see in the picture, the white thing on the side was actually our plant. The plant inside our eco dome got so hot, that it was actually bleached and turned white. When we saw it again, the plant was stuck to the side of the container.
- When we first looked at our eco dome, we thought that someone had played with it and messed everything up because everything looked dead, and the only thing left inside was the soil. We then realized that everything had just dried up.
- When opened, the eco dome was very very hot we think that this happened because we left it would in the hot sun, and everything pretty much dried up.
- How have other people made eco-domes?
Other people have also been experimenting with different kinds of things, some people thought there was no need to add water, some people put a cap of water, and some people put tons and tons of water inside. Other groups have started to get the idea of how everything works, and they understand the basic things that are needed to keep their cricket/grasshopper alive.
- What is needed to provide sustainability to all organisms?
An obvious thing that is needed to for the grasshopper is food, water, and oxygen, those are the main things that are needed. The grasshopper would get the food from us, they would get the water from the humidity inside the container, and the grasshopper would get the oxygen from the plants.
- How much of each material is needed
We think that would don’t really need a lot of things, just a reasonable amount of things are good because if you add too many plants, then each plant would not get enough Co2 because it is divided between all of them. Therefore, you just need to add a reasonable amount of things.
- How does each organism interact with the others?
The grasshopper needs the plant and the plant needs the grasshopper because both of them are using each other. The grasshopper uses the plant for the oxygen, and gives the plant Co2, the plant uses the Co2 and gives back oxygen to the grasshopper. So everything inside the eco dome pretty much needs each other in order to survive.
- What cause the observation and results?
We think that the reason everything dried up was because we left it out in the hot sun, and it was too hot. That is why everything pretty much evaporated and dried up. The temperature caused because we left it out in the hot sun, the dead plant was also caused by the hot burning sun, and pretty much everything was caused by the hot sun.
This video summed pretty much what everything happened when we looked inside our eco-dome.
