Reflections

Raphael Goh
I find that it is important to have a questioner who "criticizes" our ideas and helps us to reconsider and perfect our project. I also realized that we need a good leader who can lead the team and get things done.

Seah San Yong
I know that teamwork is essential and i think that we must find out more about solar energy. I also want to find out how does the Sun's Light and Heat energy works, I can read magazines or checking out in the internet or even going to the library to read journal to find out more.

Jonan Siak
I think that we must encourage our teammates when they need encouraging

Bryan Tan
i think that we have to work together to finish the project on time and we also have to work together to get good marks.and we will also have to do our own research to finish this project with a ssuccessful solar cooker

Basic Principles of Solar Cookers


Concentrating Sunlight: Some Device, usually a  mirror or some type of reflective metal, is used to concentrate light and heat into a small cooking area

Converting Light to Heat: Any black on the inside of the solar cooker, as well as certain materials for, will improve the effectiveness of turning light to heat

Trapping Heat: Isolating the air inside the cooker form the air outside the cooker allows light to be absorbed and converted to heat and trap the heat inside.
