Climate Patterns

Did you ever wonder why it is hot in the summer and cold in the winter?

Take a moment to write down one or two hypotheses or explanations as to why it is hotter in the summer and colder in the winter.

In this unit we will be looking for patterns in seasonal temperatures and using models to explain them. We will also test our models to see if they fit with our observations.

Part One Collecting the Data

To study seasonal climate patterns we will need to collect some data. One way to do this is to observe and record daily temperatures over an extended period of time. What might be a problem with this method?____________________________

Another method we can try is to use preexisting data that someone has already collected. We can find such data on the inter-net.

Step 1 Log on to the inter-net and go to

Step 2 Type in the name of a city (other than Sydney)
You may have to select one site if there are multiple sites given.

You should see a page something like this;


Located at about 33.86°S 151.19°E. Height about 42m / 137 feet above sea level.
