Series 3: 4. Day and Night and Solar Panel
Maddie explains how the Sun doesn’t move when we go from day to night, but how it’s the Earth turning on its axis that makes the sun appear in the morning and go away again at night. She uses a special time-lapse camera at sunset to show the Earth turning away from the Sun when it is ‘going down’ at night time. Next, Maddie heads to a solar panel farm. She uses her special thermal camera to help us see how the solar panel cells collect the Sun’s energy and turn it into electricity that we can use.
