    It certainly is an interesting linear relationship! I love the idea of the lesson – is there a reason why you didn´t give the students real data to get them to plot the data and find the equation for themselves? Maybe using different variables for the axes would also be an interesting topic of disucssion for low ability.

    The plenery is an absolutely brilliant idea!!! 🙂

    • Hi Dan. Thanks for your comments. It was a long time ago and I’m trying to remember why I didn’t use the real data! Possibly I couldn’t find the actual formula or I ‘dumbed down’ the numbers a little so they didn’t become a learning barrier whilst the kids were focussed on something else. I do agree using real world data would make it more contextual and engaging. If you find the formula could you post it here?!

    Shouldn’t the independent variable be temperature, and the chirps be the dependent variable?
