In this activity, students explore the transit method of searching for planets. They plot graphs of light measurements from stars, searching for dimming that indicates the presence of a planet, and calculate its size.
By the end of this activity, students should be able to:
- understand the transit method for detecting extrasolar planets
- understand that, even though distant planets cannot be seen, their presence can be detected by their effect on something else
- use data to predict scientific outcomes
- work with other people to achieve a shared goal
- plot a line graph.
