Light ~ Activity 4<br />
Make a solar oven<br />
What you need:<br />
• 2 polystyrene cups<br />
• large family-size<br />
yoghurt pot<br />
• tissue paper<br />
• baking foil<br />
• black paper<br />
• large sheet of stiff<br />
paper<br />
• plastic food wrap<br />
• adhesive tape<br />
• sliced apple<br />
Humans have been relying on the heat and light from the sun for a<br />
million years. If the sun was to disappear, animals and plants would<br />
not be able to survive on the earth. The sun’s rays bring large amounts<br />
of light to the earth. This light is converted to heat energy within the<br />
earth’s atmosphere, which holds much of the heat ‘in’.<br />
Energy from the sun is called solar energy. This energy can be trapped<br />
to warm our surroundings, our homes and ourselves!<br />
What to do:<br />
• Line the polystyrene cup with black<br />
paper and place the sliced apple in it.<br />
Tightly cover the top with plastic wrap.<br />
• Cover one side of the sheet of paper with<br />
foil. Wrap it around the cup and tape it<br />
in place.<br />
• Place the cup and black paper cone<br />
into the second cup. Place this inside<br />
the yoghurt pot. Use tissue paper to fill<br />
in the gaps between the cup and pot.<br />
• Leave your solar oven in the sunshine<br />
and angle it directly towards the sun.<br />
