Ecodome Day 37

Observations

  • There were a lot of mold formed on the sunflower seeds.
  • The grass all turned brown
  • There were brown circles stuck on the wall of the eco dome. We are predicting that these are the feces of the grasshoppers.
  • Some leaves started to change their colors
  • There were not much water left on the plastic water bottles
  • The lettuce were becoming very dry
  • The grasshopper died on top of the plastic wrap
  • Sunflower seeds are all gone
  • Lettuce became smaller

Conclusion

There were a lot of mold formed on the sunflower seeds because inside the eco dome was too humid. And as I posted on my last post, according to my research when the place is too humid, the bacteria started to form on the food. And also I think that the grass all turned brown since the place was too humid for grass to survive. And this time, we had no roots for the plants, that might be the reason why it all turned brown. I don’t know what the brown circle was formed but after the grasshopper consumer something they might’ve left their feces there. And the leaves started to change the colors since the leaves were exposed to the oxygen since we didn’t wrap the plastic wrap properly. And since we didn’t wrap the plastic wrap properly, the grasshopper died on top of the plastic wrapper.

The leaves were very dry since they couldn’t really absorb the water around the plants.

This is the ecodome that we saw after WWW

Changes that we made in our last ecodome

  • We had put in different size of rocks because there were no rocks left and for last time we wanted to use different type of rock
  • We had put in different type of grass.
  • We put in different type of soil because of the plants
  • And we put in 150ml of the water in the plastic bottle because of the condensation forming in the wall of the eco dome

This is how the final ecodome looks like

Ecodome Blog Day 23

Observations

  • We had a lot of water vapors on the walls of our eco dome.
  • We had a lot of mold growing on the corn.
  • The lettuce was all dried up and it was very hard.
  • The corn had green stems growing from itself.
  • All 3 grasshoppers were gone, we couldn’t find our grasshoppers
  • Our plants were starting to get rotten.

Conclusion

Changes that we made

  • We had put in less plants with less leaves because the shop didn’t sell a lot of those plants now.
  • We didn’t put in any worms because last time all the worms died.
  • We put in sunflower seeds instead of corn since the corn had plants growing on them, so we planned to put in sunflower seeds.

Research

<http://animals.mom.me/kind-food-grasshoppers-eat-10974.html>

The enzymes in their saliva and stomachs enable them to digest even the driest plant matter. They’re particularly fond of cotton, clover, oats, wheat, corn, alfalfa, rye and barley, but will also consume grasses, weeds, shrubbery, leaves, bark, flowers and seed.

 

ELA Quarter 2 reflection

What was your biggest success?

My biggest success this quarter in language arts was making note cards. When writing the paper, the note cards made it easier to figure out the sequence. Researching was not hard because I was able to easily find facts from the databases we learned.

What was your biggest difficulty?

My biggest difficulty was the introduction and the conclusion. I had difficulty writing the introduction because it was really hard for me to think of a way to hook the reader. I had to change the beginning of the introduction multiple times. Another difficulty I had was the conclusion. I had hard time writing the food for thought. Because I had to leave the reader thinking about something, I had to think of something creative but I couldn’t think of any.

What would you have done differently?

If I could do this paper one more time, I would change my question. I found that because most of the time my research answered my question, the explanation of the research was very hard to write. My topic was interesting to me however I thought it was hard to make up the body paragraphs.

Ecodome Day 7

Observations of Ecodome

  • There were water droplets formed on the sides of the ecodome
  • There were greenish molds formed on the oatmeal
  • The amount of oatmeal didn’t change- they didn’t eat them
  • Amount of lettuce reduced by a bit
  • Plants and grasses started to turn brown
  • Amount of water in the bottle didn’t change.

Conclusion

Difference we had from the brainstorming

  • We had put in less plants with less leaves because the shop didn’t sell a lot of those plants now.
  • We didn’t put in any worms because last time all the worms died.
  • We put in sunflower seeds instead of corn since the corn had plants growing on them, so we planned to put in sunflower seeds.

Our 1st ecodome

Research

<http://www.answers.com/Q/How_long_grasshopper_survive_without_food?#slide=2>

Grasshoppers are able to stay alive for 2~3 days. Grasshoppers need plants such as grass, crops, and leaves to live. They get fluids they need from their food. We had put in many grass for them to eat and stay alive.

<http://www.biokids.umich.edu/critters/Acrididae/>

Most grasshoppers prefer dry open habitats with lots of grass and other low plants, though some species live in forests or jungles. Many of the grassland species invade farmer’s fields too (Copy paste from the link). Since they prefer dry open habitats, we had put in many plants and patch of grass for them to adapt the environment.

Ecodome Day 1

We started brainstorming & building the ecodome

Brainstorming

Design’s components

  • Moist soil (to make an environment for the worms)
  • 3 pot of ivy plants (for oxygen)
  • A plant that grows well without water
  • Pebbles to drain the water to the bottom of the container.
  • 5 earthworms (to make the soil healthy)
  • Grass to cover up the soil
  • Plastic bottle → inside that there is water
  • Oats
  • Corns
  • Vegetables
  • 1 Grasshopper

Final ecodome

In Quarter 1 Language arts, we focused on writing Newspaper articles. In group of 5, our group designed newspaper that we wrote.

I think for newspaper article, one thing that I did good is that I had a lot of facts about our topic. My topic was how animation teaches kids a life lesson. I got facts and overview rate for the movie and the comments that the people gave. (Some quotes that they gave were show below in my article.)  I think I had a lot of parts that I could’ve improve to write a better article. One of the things that I could’ve improve is my grammar mistakes and also I think I should’ve chose a more easier topic for myself. Newspaper should say facts but my topic was a topic where people can say their own opinions. For example, for ‘Finding Dory’ many people thought of different life lessons that movie taught for the kids. When doing journalism, I learned how to write a writing with a bit more formal than other writings that I’ve done during in the past. Also, I learned how to organize the article in to a newspaper format, and I think by this I got to interact more with the lower grades such as Grade 6 and 7 when doing an interview. I think Quarter 1 was a time for me to get more close with my friends and also get to know more about my teachers who I am going to spend the last year of middle school. I think it is not very stressful yet and I hope to try this again next time.

Metacognitive Reflection

In this project on Renaissance fair project , we focused on learning about Leonardo Da Vinci’s life. This is an important skill because he was a great artists during the Renaissance.  One thing I improved while working on this project is my ability to know more about Leonardo Da Vinci and what types of art works were famous during that time. This blog post provides a reflection on my work, as well as a sample of what I accomplished.

– What helped me stay organized?

The question paper that Mr Post gave me stayed very organized. It had put some questions about what we needed to finish. It helped my partner and me to see what we needed to finish until the last day. It helped me not forget the things that we needed to do.

– How did time impact my work?

I didn’t think that we had a lot of time because we only had about 1 week to finish the project, but the interactive that my partner and I planned to make was hard and also we needed to have a lot of time but we finished in our time.

Water Cleaner 3

What did your group do today?

For today, our group completed and tested out our design. We finish building the machine for our 3rd step and tested the two other steps out as well. We built a protection for the machine and test out measurements to see if our design would fit in the solar box(?). We tested out our design during lunch and watched out for upcoming changes and result. As far as I’ve seen, I don’t think we would be able to produce clean water 500ml in half an hour. Since, even after 1hour, I didn’t see any progress.

What methods did you use to remove bacteria? What methods did you use to remove salt?

We removed bacteria by adding vinegar and bleach. For this, we’re using the chemical method to remove the bacteria by balancing the vinegar and bleach. To remove the salt, we’re using the heat from the solar power to evaporate the water and get the water. 

What methods did you use to remove sediment?

We took a beaker. And around that beaker, we tied a towel on top of it with a yarn so it would go on top of the beaker. Following those steps, we added gravels on top of the towel. We then pour our unfiltered water in and the sediments will then be removed.

Would you drink your water after it has passed through your filter system? Why or why not?

Our group haven’t had a look at our filtered water yet. I think will try to drink it. I saw the results of 15 minutes and it actually looks pretty clean. Since we worked really did brainstorm and think clearly through a lot of our steps, so I think our water could be really clean.

Water Cleaner 2

What methods (chemical, mechanical, biological, or natural) are you using in your design?

We are using both natural and chemical method for our design. For natural method, our group uses water cycle For chemical, we’re using different types of acid for filtration. Using the natural method, we’re going to evaporate the dirty chemical for it to be filtered. For the chemical part, we’re using acid (bleach and vinegar) to filter our water too.

What steps do you need to do tomorrow to improve or test your design(systematic testing)?

We need to find a way on how to connect all of our steps together. For making out water to a drinkable water, we decided on making 3 seperate steps using different materials. So for our next class, we need to finish designing the 3rd step machine of our design and find a way on how to connect them together.

What is your prediction of how it will work?

I personally think that our group is heading in the right direction, meaning there might be a chance that it would work. However, I think that it will take more time than 30 minutes to get that much amount of water. Connecting all of the steps together might be hard to do, but I think we will eventually find a way. So if we succeed on connecting the steps together, then it will possibly work and meet all of the requirements.

Water cleaner

  • How did you work with your group to brainstorm?
    I wrote down most of our information and offer my own insights on a few other ideas. In our group, since our group worked well together. We came up with a lot of solutions and did consider the requirements through out like what will succeed and what is likely to fail, and also we considered if the people who are poor can afford these materials. Therefore, we came out with a solution to use other common materials for our design and produce enough amount of water for 1/2 hour.
  • What ideas can you offer?
    I think that maybe we could add more liquid into the flask for backup and faster production rate. If we add more liquid into the beaker, our cleaner can purify it faster and produce more liquid.
  • What is your group’s next steps?
    Our group next step is to test this out. For the next time, I think that we would test our idea out, maybe make a few adjudgements if needed, find better solution or replacement (if needed) then test that idea out. We might have to repeat these steps again just to find the best solution.
  • What should you bring?
    I’m bringing more cups to support our idea.We needed more cups to make our apparatus that connects from the flask on the left side to the flask on the right. Photo on 5-16-16 at 12.54 PM
