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 />
