To study the daily movements of tides.
Measuring how fast the tide comes in and the height of the incoming tide during different hourly intervals of the day.
In most regions of Atlantic Canada there are two high and two low tides each day. Some places have only one tide. Refer to the introductory module for more information.
These activities can be done as part of a field trip.

Obtain tidal charts from your local newspaper. Tide tables can also be purchased from your local Fisheries and Oceans office, bookstores, your provincial Geographic Information Centre, or the Canadian Hydrographic Service in Dartmouth, Nova Scotia (see references).
Familiarize yourself with the charts.
Try to pick a day for your trip when you arrive at a high tide or at least at ebb tide.
Check the tidal range chart above and mark a stick in intervals for measuring the height of the incoming tide.
