Introduction
Lesson 3
In lesson 3, the students will start to identify events where one cannot happen if the other happens. Developing more mathematical language along the way by using such words as possible, impossible, certain, and uncertain can be added to their chance vocabulary. They will be learning about the prediction of weather and how some aspects of weather prediction can be certain, but other aspects uncertain.
Task
Task to Achieve Goal
- Getting into pairs you will come up with as many types of weather, and words relating to weather, you can think of eg. sun, rain, cloud, thunder etc.
- When you have your list of weather words, go through them and for each one put down what needs to happen for those condition to exist.
- After making your list watch the video, take note of how they describe the conditions and the type of weather that results.
- Then in your pairs discuss what you think the weather will be tomorrow. By working through the chance of what conditions are impossible and those that may occur, you will have a good shot at predicting tomorrow's weather.
- At the end of the lesson we will get together and see how all the pairs arrived at their predictions.

Evaluation
Discuss Results
In the case of predicting the weather forecast, it is not an easy task, but working through there will have been some aspects you may have been able to rule out. For example, if it is the middle of Summer and you live in the north of Australia, you can say that snow will be impossible. By working your way through the chance of certain weather events occuring, or not, you can narrow down the chance of error.
Conclusion
What We Learnt
Weather is something we are all exposed to in our daily lives and would know that there is a forecast for each day, but do you know how those forecasts are arrived at? Much more research goes into it than what you have done here, but this is the premiss of taking out the weather that is impossible to occur. This means the research can be narrowed to concentrate on more probable outcomes. For example, when looking at the south of Australia, in Winter time, you can spend more time looking to see if it is going to rain, and not if there will be a heatwave.
