Semiconductors
Semiconductors are an important part of CCD cameras (Charge-coupled Devices). They help to convert light into a current in the technology.
- n-doping
Here, silicon (Si) is doped with a material like phosphorus (P). This replaces some silicon atoms in the crystal.
The silicon bonds with the phosphorus but leaves behind an extra electron. This is loose inside the crystal and can be freed easily. This lets it conduct electricity.
The electrons that are freed have a negative charge, so the process is called n-doping.

Start a STEM Club
Are you part of a STEM Club (STEM stands for Science, Technology, Engineering, and Maths) or would like to start one? Did you know The Schools' Observatory have created a set of STEM Club booklets?
Make Your Own Spectroscope
Spectroscopy involves splitting light into its different wavelengths. Each chemical element emits or absorbs a unique spectrum&n
How Do Satellites Stay In Orbit?
A satellite is an object which orbits another. An orbit is the curved path that an object in space takes around another object.
Find the Moon Missions
Did you know that 6 Apollo missions landed on the Moon? The first was Apollo 11 in 1969. The last was Apollo 17 in 1972.
Light and Mirrors Card Match
Explore Light
Astronomers use telescopes to see objects far away in space. Did you know that we can only see an object if it emits light or if it reflects light?
Telescopes Quiz
Telescopes are used to magnify distant objects. They are a vital tool for astronomy. Over the last few hundred years, scientists and engineers have built bigger and better telescopes, revealing the mysteries of the Universe. But how much do you know about telescopes on Earth and beyond?
