Kenneth Choo Qi Yuan's Week 12 Reflection

This week,our group has posted the first of our drawings on our group blog.I feel that this is a step towards reaching our goal of being able to condense water in less than half a day.We can try to include more drawings in our group blog.

David's week 11 reflection

This week, we have used Google sketch-up to design our water-cleaning tool. All we have left to do is to meet up for a final experiment and also take some pictures and perhaps videos so that people can have a clearer idea of how this tool is made and also how it works. I hope that we can think of some ways to further improve on our project.

good work done

Good work done!

Group's first drawing of project

This is our group's first drawing of our project.Basically,a small container is held to the metal bowl by scotch tape.The metal bowl carries the dirty water.In the diagram there are two curves at the end of the bowl.The first curve is the level of the dirty water and the second curve is the bottom of the metal bowl.We are still trying to draw the layer of ice cubes and the plastic around the bowl and on top of the ice.

Kenneth Choo Qi Yuan's Week 11 Reflection

This week,our group did a drawing of our project and showed it to Ms Lum.I realised that drawings helped us to better imagine how our project is going to be like.Hopefully,we can use more drawing so that we can think of new ideas to improve our project.

Keith's 10th Week's reflection

Since we had to consider the factors of evaporation,Ms Lum has shown us some of the factors that affect the rate of evaporation: humidity and the brightness of the sun.I think that still have a few weeks to experiment before our group's final presentation, henceforth, we should also concentrate on the group's final presentation.

Keith's 9th Week's reflection

I have realised that in our survey, the number of people who answered the survey were very few.Resulting in having had to answer the survey a few times ourselves to test if the survey was working,which means that only about three people helped us complete the survey.However,we as a group are thankful to those who answered the survey for the group.
