Look at these animals. How does the temperature of their habitat affect the size of their ears?

Look at these animals. How does the temperature of their habitat affect the size of their ears? Desert Mouse Lemming (mouse like creatures found in artic)

So the evidence suggests, animals in hotter climates have larger ears Why do you think this may be?

I think animals in hot climates have bigger ears so they can fan themselves to keep cool I think animals in hot climates have larger ears because sound waves do not travel as well in the heat I think animals in hot climates have larger ears to keep the flies away? I think animals lose heat through their ears so animals in hot climates need bigger ears I think animals in hot climates have larger ears because it is harder to catch prey so they need to hear REALLY well

You are going to plan an experiment to test your ideas Planning an investigation Step 1 Decide what you will do to investigate your question Step 3 Getting Accurate results What variables do you need to control to make it a fair test? Step 4 Resolution What scale of measurement are you going to use? Step 2 Independent Variable What are you going to change? Dependent Variable What are you going to measure? Step 6 Do you need a control in your experiment? Step 5 What equipment are you going to need? Step 7 What do you Predict will happen and why?

Recording your Results Design a table to collect your results in This is usually the thing you change These are usually the things you have measured NEVER FORGET YOUR UNITS!!! (e.g. s, m, cm, N) Use a PENCIL and RULER

What did your results tell you?

Evaluating your Evidence How Repeatable are your results? How Accurate are your results? Do your results show a strong pattern? Did you do enough conditions or should you have done more? Are all of your repeats similar? Did you do your anomalies again? Are the results close to the line of best fit? Should you have thought more carefully about your plan?

Are your results as good as other peoples in the class? How would you improve your experiment if you were to do it again?

So is this the only reason animals have big ears?

Can you find out why Indian and African elephants have different sized ears?
