The solar cell collects the Suns energy. The area of the solar cell matters You can test this out using a lamp in the laboratory So how can we investigate only part of the cell area without damaging it? Lets use a mask to cover some of the solar cell area

The Sun shines down at an angle, does this affect the energy the solar buggy can store? You can test this out using a lamp in the laboratory The Sun is so far away that the angle doesnt matter OK, but we need to think about how to measure angles

Clouds block out light from the Sun. Will the buggy work on cloudy days? You can test this out using a lamp in the laboratory We cant make clouds in our school lab OK, but we need to think about how to simulate clouds between our lamp and solar cell

Does the energy the buggy stores depend on the colour of the light? You can test this out using a lamp in the laboratory We dont have lamps of different colours in our lab OK, but we need to think about how to change the colour of the light striking the solar cell

Does the type of lamp used to light the buggy affect how it works? You can test this out using different lamps in the laboratory Old style light bulbs get a lot hotter than energy saving ones Maybe not all of the energy from the bulb is visible light

The solar cell collects the Suns energy. The brightness of the Sun matters You can test this out using a lamp in the laboratory So how can we investigate how the brightness of light affects the solar cell? The light gets dimmer as you move away from a lamp

The solar cell collects the Suns energy. How long it is in light matters You can test this out using a lamp in the laboratory So how can we investigate how the time the buggy is in light affects the solar buggy? We will have to make sure the investigation is fair
