Where and How does the living things interact? Overall Opinion

Observing all of the grasshoppers and the ecodome we made, it wasn’t effective that 5 out of 6 grasshoppers(including attempt 1, 2 and 3) died. I felt sad for them because they died for being observed by human and surviving in a poor condition of ecodome for over a week. We’ve been thinking about the water tank more water than the hole of the tunnel, then we’ve forgotten that the water above the hole flows over the tunnel and make the ecodome full of water. The next try that is the attempt 4 will be using a single ecodome and use a big one that all water, soil, plant and 2 grasshoppers fits and make the best condition of ecodome for both grasshoppers to live.



Where and how does living things interact? Introduction

Ecodome is for organisms to live. Our ecodome project was to build a habitat for the grasshoppers whether it is a good place to live or not. Me and my partner Yeojoon’s ecodome was connecting 2 big bottles with a plastic bottle. One bottle is filled with soil, plants and sunflower seeds for the grasshopper to live and the another bottle was the water tank filled with water for supplying hydrogen.


  • The size of the container is different(one is bigger, one is smaller).
  • Chose longer than wider container because of the plant height.
  • Made the bottle horizontal so it flows a bit amount of water.
  • Calculated to input soil lower than the water tunnel.

Nov.28th Day 25 Attempt 3

The third attempt had the same result as the second attempt because both of the grasshoppers were founded dead floating around the water. The water covered the ground and also smelled more. We’ve tried the same function of ecodome except closing the holes tightly that the water doesn’t flow to the ecodome as the second trial to see if there is a difference, but didn’t have any. I’ve used the same plant as the first and second attempt, and completely rotten after over amount of water and the smell.

After me and Yeojoon cleaned the ecodome container, there was fungi growing on the dimension of the plastic container hiding from the soil. Even seeing on with our eyes, the ecodome that we made was hard to live(no ground because of the muddy soil, plants dead, creatures drowning with no hydrogen available). Our last attempt is trying to save both 2 grasshoppers and with a different construction by only using ecodome, we are going to include soil, plant, and water at the same place.


  • The grasshopper founded dead with its body colored brown
  • The soil mixed with water
  • A plant grew when the water was locked in the soil
  • Leftovers from the soil are floating around

Nov.15th Day 14 Attempt 2

Our group input the same amount of soil on the ecodome, both with the same plant. We also glued the part with the tunnel and the ecodome that was separated a part and made a whole so that the water leaked out, also put the same amount of grasshoppers. We put more water on the water tank because we thought that some water will be mixed with the soil so it would be muddy, that won’t help, so put extra amount for better hydrogen supply.

As the result of observation we’ve seen, the grasshoppers didn’t eat sunflower seeds at all, so we excluded sunflower seeds and cobble stone that was useless for grasshoppers to live. We waited for the same the same days as before. The result was 2 grasshoppers founded dead floating on the top of the water. The water tank flowed too much water to the ecodome that smelled very much when it was mixed with soil and also the root of the plants almost died.

  • Grasshopper founded dead bleeding some
  • Water mixed with soil
  • Moss looking at the corner of the container
  • Bubble of dirt floating around the water

Where and how does living things interact? Attempt 1

Nov. 2nd Day 1 Attempt 1

We put one quarter amount of soil and cobble stone on the bottom of the ecodome. Then we put a plant that supplies oxygen for 2 grasshoppers and attach its body in the leaf instead of the soil. Also, me and my partner included sunflower seeds that is edible for the grasshopper not just suppling water for living. For the last construction, we attached a tunnel on the side and the tunnel was the connect between a water tank and the ecodome that supplies hydrogen around the air or let them drink.

After we left the 2 grasshoppers for few days in the ecodome, one of them died coloured with their body in brown. It also bleed after its body went into smithereens. The theory we considered that one of them died is because that the sand and the water was mixed that lacked of space living on ground, also had polluted hydrogen supplied. A miracle scene, the another one barely lived hiding through the leaf, evident that it ate some leaf with shown by the teeth print.


  • Plants are being eaten by the bite
  • Hydrogen attached to the container
  • Plants living healthy by the support of water
  • Root being spotted by soil
