*(c) More than two thousand years ago the Earth was believed to be at the centre of the universe as shown in Figure 13.

The planets, the Moon and the Sun were believed to be in orbit around the Earth.

In 1543 Nicolaus Copernicus proposed that the Earth was a planet, and that the Earth and the other planets orbit around the Sun. This model is shown in Figure 14.

Discuss how evidence has changed our views of the universe.

A student investigates what happens when light travels from air to glass.

Figure 15 shows some of the apparatus used in the investigation.

Figure 17 shows a Geiger‑Müller (GM) tube used for measuring radioactivity.

Describe how a teacher should use a Geiger‑Müller (GM) tube to compare the count‑rates from two different radioactive rocks.

A hospital uses a radioactive isotope with a half‑life of 6 hours.

A technician measures a count rate of 80 counts per minute (cpm) from this isotope.
