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.
