This time, we created our fourth eco-dome. We are going to leave our eco-dome over the Christmas break.
Here are some components in this eco-dome.
This is the reflection for the third eco-dome.
We kept our third eco-dome over a week to try to see if our eco-dome is efficient. However, it turned out that both of our crickets were dead.
We cannot tell when exactly the crickets died because we couldn’t check on the eco-dome for a week because of WWW, but I predict that they died after a day or a two since the plants are completely brown, and the dead bodies of the crickets are nearly decomposed.
- All plants are dead. They are all brown and soggy. It either didn’t have enough water, carbon, or sunlight. We put the eco-dome behind another group’s eco-dome, so it probably didn’t have enough sunlight. However, I can see that the water evaporated because there was water on the top of the eco-dome. We had the same amount of water from last time, so I predict it didn’t have enough sunlight.
- Not all of the water evaporated. The soil is still moisturized. Again, we can predict that it didn’t have enough sunlight because there is more water left than last time.
- One cricket that was eating a lot of food when we closed the eco-dome looks like it ate all the food in the eco-dome because we don’t really see any left over food.
Research and Reflection:
- Crickets like to eat red bell peppers.
- Crickets eat carrots, cabbage, and more. They can pretty much eat anything.
- It is better to have sponges or soaked paper towels because crickets drown easily.
- Crickets like to have something to hide or go underneath. We used the coconut skin in the first eco-dome, but we didn’t use for the rest of our trials. I think we should use the coconut tree skin again in our next eco-dome.
This is our third eco-dome.
In our last eco-dome, the cricket died. We think the cricket died because it didn’t have enough food.
Things that we changed from the last eco-dome:
This is a video explaining the changes.
- We didn’t use the plastic bottle that we had because it seemed useless since the cricket was not in there and it just took space.
Please click on the image to see the picture better.
- Added more food (8 cabbage, 5 slices of carrots, 3 slices of green bell peppers) Crickets are omnivores, but they are mainly herbivores.
- Same amount of water from last time (25ml of water for the soil and sprinkled some water on the plants).
- 8 plants because last time, all our plants were alive.
- 2 crickets: we changed the number of crickets because we found out that crickets eat each other. We thought that if a cricket is hungry, then one of them will at least survive by eating each other.
- We kept the sponge because it helped the cricket to have water without having a paddle of water . We saw other groups having their crickets drown itself.
This is the conclusion for the second eco-dome.
Observations of Ecodome:
- All 8 plants were alive (which means we had enough water
- the cricket was dead
- The two lettuce leaves that we put in were untouched and molded
- less foggy than the first eco-dome in the container
- The cricket was dead near the plants
- The water in the containers are not fully evaporated because we can still feel the moisture when we touch the soil
- The plastic bottle had the most water around the surface compared to the plants and soil (maybe it was harder to evaporate?)
This is the conclusion video for trial 2:
Reflect & Research:
- Other people had fewer plants, but the crickets still survived. They put more food than us.
- Other people put corn inside their eco-dome and the cone was still growing.
- Crickets like to eat rotting food, but they are omnivores so they can eat vegetables, fruits, seeds, meat, wheat
- The plastic bottle seemed like it didn’t work well because it looked like it’s useless, and the cricket was not using the bottle at all.
- The charcoal worked well is absorbing the water because we didn’t see any puddles of water even though we put a lot of water.
From the research and mistakes that we found, we created a second eco-dome.
Changes and Components that we have in our second eco-dome.
- 1 cricket because we didn’t want them to eat each other. Also, we wanted to test this design first if we can keep one cricket alive.
- We made the container for our eco-dome horizontal because the other design seemed like it didn’t have enough space to plant more plants.
- 8 plants because last time we had 3 plants, but it was not enough to create oxygen for the cricket.
- 25 ml of water for the soil because last time we had 10ml of water, and it was not enough for the plants to survive and photosynthesize (2 out of 3 plants died)
- We sprayed water on the plants just to make sure it was enough water on the plants.
- Added a sponge for more water, but we used the sponge because it won’t be too much in the air.
- Charcoal and rocks to soak up water because we used a lot more water than we did last time, so we didn’t want it to have too much. Charcoals and rocks soak up water for the soil.
- We didn’t put the plastic cap that we had last time because it seemed that it had water in it, and we thought it might be dangerous for the cricket since we saw some crickets from other groups drowning.
- A little amount of food (cabbage) because we didn’t want the food to get molded and rotten.
- Soil from the student garden and plants from the student garden. We used the plants and soil from the same place because we thought that it is easier for the plants to have the same soil as before to grow.

This quarter in language arts, we wrote an informational paper with research. Just like social studies, we used note cards to organize our research and our topics.
The biggest success I had during this unit was researching. I think I did well on researching because I had enough facts and quote to support my thesis. I also used different types of resource for my fact. For example, I used interview videos, websites, Britannica, Culturegrams, Ebsco, and books. I think using a variety of source for a research paper makes the paper supported since I can use different facts from different places and people. To add on, my works cited page was formatted properly. Therefore, I think I did well on researching the facts for my paper.
The biggest difficulty I had was writing the introduction and conclusion. It was hard for me when we had to come up with a food for thought sentence. The food for thought sentence makes the reader think after reading my paper. I thought it was hard because you have to be creative. It took me the most time to write because it was hard to come up with a sentence that is related to my topic that makes the reader think further more. I think my food for thought sentence is pretty good in my paper. It grabs the audience’s attention and I think my sentence is very creative.
If I can do it again, I would want to do the “CRAAP” test for each of my sources. I learned that databases have websites that are trustworthy such as Britannica. However, I couldn’t find facts from the database because my topic was about Japan and Vietnam. If that happens, I would want to move on to videos and websites that look trustworthy. I think I did all these, but I think I should have done the “CRAAP” test for each of the source just to make sure.
Overall, I think my research paper was done in good quality.

This the reflection for the first design of the eco-dome.
Our cricket was dead after a day.
Here are some of the data when the cricket was dead.
- one plant was dead
- All 20ml of water evaporated.
- very foggy with a lot of water around the container
- The plants were dying with brown root.
- The food was a little bit rotten.
- The cricket was dead between the plants and the tree skin.
- The water in the plastic bottle evaporated.
This is a video of the conclusion for the first eco-dome.
- We should add more water for the plants because plants need water, sunlight and carbon dioxide to photosynthesize.
- Crickets need oxygen and water to have cellular respiration
- The soil should be from the same soil where the plant was planted
- Photosynthesis and cellular respiration will help the crickets to survive because when the cricket can get oxygen and sugar from the plant, then it will make energy. Then, when crickets produce carbon dioxide and water for the plants, the plants would be able to provide oxygen for the cricket
Components for the eco-dome.
- 1 Cricket (they might eat each other if there’s two and they might produce the number of crickets)
- A little moisturized soft soil for plant and air (should be moist because plants can grow better, and when the water inside the soil evaporates, it will turn into air)
- 10ml of water for soil (to moist soil)
- Cabbage and lettuce (for food)
- Stone for decoration
- 3 plants to produce enough oxygen
Changes that we made when we actually built the eco-dome:
- We changed the number of plants because the plants were too small.
- Added the coconut tree skin to make the eco-dome not too humid.
- We added different types of vegetables for the plants (carrots) because we didn’t have the material yet, and we thought it would be better to have different types of vegetable than just cabbage and lettuce.
- We added a bottle cap for a little amount of water to make the eco-dome slightly humid
- We mixed different soils since the soil from the plant was different.
- We changed the amount of water for the soil because we thought it’s better to have moisturized soil then dried soil for the cricket
- We used more water than the original idea because the amount that we thought was too little for the amount of soil we had.
In Q1, we created a newspaper. I wrote about where students in eighth grade traveled during the summer. I think my design of the newspaper was good because it had facts and data at the side to make the newspaper more interesting. Also, I asked a lot of people about their travel, so I think I had enough quote to support my newspaper. One thing that I think I did bad is the introduction. I wrote an introduction that wasn’t quite in a newspaper form. My introduction was like an introduction used in an informational writing. Therefore, I would like to improve on my introduction if I can do it again.
During this unit, I learned that we need to use evidence and facts to make the paper interesting for the readers. I think I was good at researching when writing a newspaper. I also learned that there are different types of writing in this world. I was used to narrative writing and informational writing, so I wasn’t used to writing a newspaper. I enjoyed writing the newspaper because I find newspaper interesting when I read, and interviewing people with surveys was fun for me.
In general, Q1 was fine for me because I didn’t struggle that much in language art, or in other subjects. In Q2, we will be writing an informational paper, and I think I am used to that. So, I hope I can do a good job in researching and analyzing the facts. I thought eighth grade was going to be harder, but I don’t think it’s that hard right now. It changed a lot from seventh grade, but I didn’t find it hard. I hope Q2 will be just like Q1, but a little more exciting and challenging.
This quarter in Social Studies, we learned about the scientific revolution.
I chose Leonardo da Vinci and wrote a paper for him. I think my paper was detailed with the research that I did. I tried to include facts that are related to my topic for each paragraph. Additionally, I think I was capable of citing the source that I used for my facts in the paper. However, there were some parts that I think I did not do as well. I wasn’t getting the background information of the Scientific Revolution, and I only focused on Leonardo da Vinci. I think it was better to get the background of the Scientific Revolution more in order to understand the accomplishments and how he contributed the scientific revolution.
For the paper, we had around a week in class to research about our person. As I mentioned before, I researched facts that are related to my reasons why Leonardo contributed the scientific revolution. I was comfortable with the research because I was able to determine whether the source was useful or not useful. Also, I was able to determine if the source is a trustworthy source to use. I used varieties of sources such as Encyclopedia, Britannica, Brainpop, Youtube, and books from the library. I think using different types of sources is good when writing the paper because it makes your paper supported with different types of detail.

This is a minimalist poster that I created about Leonardo da Vinici
