ABSTRACT Objectives of the science and tecnology carnival is to

create the culture of innovation and designation among the students.

It is perfectly feasible to power the cooker by heat energy.

Can be convert to heat energy. Work based on the the basic principle, which convert

sunlight to heat energy and retain the heat for cooking. the panel solar cooker surface must be able to absorb

effectively and reflect sunlightinto the cooker A transparent heat trap is needed on top of the cooker

to retain the heat, and an insulator below to trap the heat.

Should be use on sunny day Between 10.00 a.m to 12.00 p.m.

INTRODUCION Source of energy – diesel, petroleum, gas may

not last very long in future Renewable energy – not subject to

deplecation Solar energy – source of renewable energy Panel solar cooker – use sunlight as an

alternative source to cook - should be protected from

strong wind - made from black mounting board which is able to absorb heat - has a portable design makes it easily

handled and transferred from a place to another place.

ObjectivesThe objectives of the project are:To create the culture of innovation and

designation among the students;To instill the responsibility among

students to use energy sources effeciently;

To increase the creativity and compotitiveness among the students;

To use the solar energy as a alternative source to produce heat energy

SPECIFIC OBJECTIVESThe project was carried out specifically :To increase the student’s understanding on

the science process, manipulative skills and science and technology concepts.

To desing the cooker that can be used sunlight energy opltimally and convert this energy to heat energy.

To design a panel solar coooker that is able to reflect the sunlight onto the cooker, absorb and retain the heat in the cooker.

DISCUSSION AND CONCLUSION

Nowdays we used electrical energy power by diesel, petroleum and gas;

This energy may deplete in the future;

So, we have to used the renewable energy such as sunlight;

We have make a portable panel solar cooker to solve the problem;

This solar cooker functioning on the sunny day;

This solar cooker change energy from the sun to heat energy which is used to heat the water;

Dark and dull are a good absorber of heat. Meanwhile, white and shiny surface is a better reflector of heat;

So, we choose black mounting board to absorb heat and shiny materials( aluminium foil) to make the reflector;

The reflector is to reflect the light to our panel solar cooker;

This panel solar cooker collect and trap the energy from the sun so that it always hot;

The cooker can reach higher temperatures, which is enough to boil water.
