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...

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...

In this activity developed by the Institute of Physics, students use iron and sand to model the composition of the Earth and estimate what fraction of the Earth is occupied by its iron core. After completing this activity, students should be able to: *Measure mass and volume. *Calculate density from mass and volume...

In this activity developed by the Institute of Physics, students investigate how temperature changes with distance from a heat source and relate this to planetary temperatures. After completing this activity, students should be able to:

*Understand that the temperature of a planet depends on its distance...

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...
