Kenneth Choo Qi Yuan's Week 6 reflection

I have found that our group is doing faster than expected.We have already managed to discuss that we are going to meet up doing the June Holidays.Our first experiment was almost a success except that we did not condense too much water.

Survey

Dear all,
there will be a survey during the March Holidays.

Week 5 reflection (detailed)

Last week, we have gathered at my house to try out the experiment. the concept worked but the experiment still failed. we figured out that we failed because the apparatus was too small. Thus, we have assigned Kenneth and Keith to get new apparatus, then we will share the cost amongst ourselves. Kenneth was to get a metal big metal bowl. Besides getting a big bowl, we wanted the bowl to be made out of metal. this is because metal conducts heat which makes the rate of evaporation faster. Kieth has stated that he would provide the clingwrap. the metal bowl that kenneth has bought cost $8, which means that each of us has to Pay $2. according to our planner, we will carry out the second experiment next week. i look forward to meeting up and doing the next experiment.

Shawn's Week 5 Reflection

Our group has decided to get together during the weekend to begin creating our condenser. Each one of us will bring the relevant materials on that day to create the condenser. We will first have mental and rough idea of how our condenser is gonna look like. But, we have to do it a few times to obtain the best result. We will then decide to on whether what are the necessary changes we need to make to the condenser. In order to improve it, and obtain the largest amount of clean water.

Keith's Reflection on week 5

What we we done so far?- Creating a condenser using a plastic container and black papeer which can condense water from unpurified dirty water into clean water.We have also managed to condense some of the dirty water into clean water but the condensed water was only half the container of dirty water we originally had.

What do we want to do next?-Replace the container with a bowl made of metal and are not going to use the black paper.

What have we learnt?-Although black is a good absorber of heat,metal is a better absorber of heat and we need metal to increase the rate of evaporation and condensation in our experiment.

Shawn's Week 4 Reflection

Our team has agreed on making the a condenser which is able to produce clean water from dirty water through evaporation. We have also agreed on who is gonna be taking on which roles in our project work. Currently, we are still in the mist of deciding what materials to use for the condenser. We have look into the internet to decide which material is the best suited for our condenser. Ms lum has also advise us to experiment and try each material to find which one suits our condenser the best.

Announcement

As David have assigned me to buy the metal bowl,I have already bought it.David,please take note.

Apparatus for purification of dirty water

Perhaps you all can use a bigger container for the purification of water.
Do look at some of the useful Internet resources whereby you can retrieve the information on how industries perform the water purification process.

Keith's 4th Week's reflection

I have suggested many ideas of how to solve the problem of decomposition of the umbrella.I have also got the group members to think of suggestions of how to curb this problem.On the meeting last week, due to shawn's failure to arrive, we stopped the umbrella project for the time being.
I have agreed with David's idea to go on if it succeeds.It is a condenser of dirty water,hence we decided to start a project on the purification of all waters.

David's week 5 reflection

This week, we have decided to forfeit the project of the eco-friendly umbrella. This is because instead of making things more convenient, the umbrella would be inconvenient and not portable as it cannot be closed. Thus, we have moved on to the new project which is the turning of any form of dirty water into clean, drinkable water. we do this by using a black bowl and putting dirty water into it. Then, we place a small container in the middle of the bowl, and cover the bowl with clingwrap. Lastly we place ice on the clingwrap to depress it directly above the small container. This works because only the clean water will evaporate and condense on the clingwrap. The clean, condensed water will then travel along the depressed clingwrap and drip into the container. The ice aids in lowering the temperate of the clingwrap to make condensation quicker.

Our group has came to my house and tried this project. The project failed because the apparatus was too small. Therefore, little water has evaporated and condensed.

On the day of our presentation, we will make sure the project is successful by experimenting again with bigger apparatus.

Kenneth Choo Qi Yuan's Week 4 Reflections/Contributions

Reflections:
The umbrella is still pending to be created.I believe that it will be created one day.If it fails,I will tell my group to try other creations that they can think of.The project has gone quite far.I hope that the project will be a successful one and I will work hard to achieve this with my group members.
Contributions:

Ideas:
I have decided to allow David's project to go on if it succeeds.It is a condenser of dirty water.

Week 2&3 reflection

I am so sorry i could not post as my internet at home is down. I cannot post in school too due to the infringement of AUP.

Week 2 reflection

Some questions that are still going around in my head…
1) how to not let the leaves decompose
2) how much to sell the umbrella
3) how many leaves does it take approximately to make one umbrella?
4) how do we connect the leaves together

3 things I learned…
1) The public will have to be convinced to buy this product as it is made out of leaves and might not be very presentable though usefull and eco-friendly.
2) we can glue the leaves together to as a method of putting them together
3) In order to score well, we should have more teamwork and not let each person do just his own work but do a little of everything together as a group.

Ideas i have to agree with
1) using the superglue to put the twig and leaves together as to form an umbrella
2) make the umbrella tilted to an angle so water flows one way down.

Week 3 reflection

Right now our progress has been rather far. we are planning to start on the practical part this saturday. We have decided to meet up as a team at my house to do the shelter of the umbrella. However, i have just discovered an extremely big problem that i have to voice out to everyone. It is that the umbrella that we are going to make is not portable. it cannot be closed/opened like normal umbrellas can. This is a very big problem about the convenience of this tool. So, I thought that we should not attach it to a bag because its not convenient. i would appreciate it if all of you could voice out your opinions so as to solve this problem.

Shawn Lai's week 3 reflection

Some questions that are still going around in my head-

What can I use to prevent leaves and twigs from decomposition? Is it possible to make the product cheap so that it can be mass produced?

3 things I learnt-

I have learnt that we have to cultivate a positive mind-set and not let a little set back deter us from our goals. I have also learnt that in order to achieve and produce our product we should keep and open mind to new ideas and advice from teachers.

Ideas that I agree with-

We should not use materials which cant be recycle. As we want to be environmentally-friendly.

Shawn Lai's Week 2 Reflection

The final product: An umbrella that is made of leaves and twigs which would be able to be attached to a bag. It would be able to shelter a man on rainy days.
What do I already know about the topic?
-I will use leaves and twigs to make objects. Leaves and twigs are also
environmentally friendly materials. We would not be using materials which are not bio-degradable as it would not be environmentally friendly.

What are the questions I want to ask about the topic?
-Is the product able to withstand the downpour of rain and still be able to shelter the man from the rain? Is the product safe? Does it dangers to the consumers?

What are the subjects/skills I can make use of?
-I can make use my understanding of biology which is taught by ms lum to aid us in our attempt to make our product successful.
-I am can make use of leadership skills to help us have teamwork in our group.


Where can I go and find information for the project?
-I can find information from books in the Media Resoure Library or from websites on
the internet and by watching documentaries relevant to the subject. I can also look up 

What do I prepare to tell others about our project?
-I prepare to tell others that the project is on the team's cooperation and our 
brainstorming skills. I also hope i am able to sell my products for the good of others

Keith's Reflection on week 3

Some questions that are still going around in my head-

What can I use to prevent leaves and twigs from decomposition?Is there a link

which we can find everything the group needs to research on?

3 things I learnt-

I learnt that I have to use the problem solving skill as constructing the product

needs thinking.I also learnt that I need to distribute the duties to different team

members so that work can be carried out.I also learnt that I must

collaborate with my friends to come up with ideas for the product to be

successful.

Ideas that I agree with-

Use superglue to connect different parts of the umbrella together.Connect one

twig with another to make it the size i want.
