Exoplanet atmospheres

In this activity developed by the Institute of Physics, students use simple diffraction gratings to observe the spectra from different sources, and deduce how scientists can work out which chemicals are present in an exoplanet’s atmosphere. When an exoplanet passes in front of its star, some of the starlight is...

The Transit Method

In this activity, developed by the Institute of Physics, students use a lamp and polystyrene balls to model how astronomers detect exoplanets using the transit method. After completing this activity, students should: *Understand that the transit of a planet in front of its star temporarily reduces the star’s...

Day and Night, Seasons

In this activity developed by the Institute of Physics, students model the motion of a planet around a star and investigate how day and night and seasons may be different on other planets. Working in pairs or small groups, students demonstrate night and day and seasons to each other. They can then go on to model...
