Adaptations and keys

Today we will be looking at animal adaptations, and how sientists use keys. Answer the following questions using the links provided:

1. Explain what the word 'adaptation' means in relation to animals - http://www.biology-online.org/dictionary/Adaptation
2. What species do we belong to? - http://www.bbc.co.uk/schools/ks3bitesize/science/organisms_behaviour_health/variation_classification/revise7.shtml

3. Go to http://mrskingsbioweb.com/worksheets/Classification%20Keys.pdf There are several animals drawn on the page, and a key below to help you identify them.  Pick an animal and see if you can get to the end of the key. Write down the steps you used to get there.
HINT - Snakes, fish, frogs and reptiles (like tortoises) are ectothermic while everything else is endothermic.
