This is an introductory activity to help you to understand what tides are
and how the moon and sun are responsible for the tides.
Firstly, why not take a look at the moon right now! Click
on the lunar image and away you go!

the moon and the tides. You may already know some answers to these questions.
Great! If so, move on to activity 2. Check with your teacher to make sure
you understand these basic ideas on tides.
Below is a series of questions and some internet links
