1) The students designed a portable solar panel cooker that uses sunlight as an alternative energy source to cook. 2) The cooker works by concentrating sunlight onto a black panel using aluminum foil reflectors, which absorbs the light and converts it to heat energy. A transparent plastic traps the heat inside. 3) During trials, the cooker was able to reach temperatures over 50°C, which is hot enough to boil water, demonstrating its ability to harness solar energy for cooking purposes.

2. 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.

3. 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.

4. Objectives
The 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

5. SPECIFIC OBJECTIVES
The 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.

6. SCIENTIFIC THEORY
The collection of heat :
 concentrate sunlight into the panel solar
cooker
 Convert sunlight to heat
 Trapping heat using a transparent plastic
 Green house effect

15. 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;

16.  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;

17.  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.
