Ignitor (2 minutes or less)
1) On a sheet of paper, write a definition of the word ‘adaptation’.
2) Explain how adaptations influence the size of a population?

Answer to Ignitor
1) Definition of an adaptation:
The behaviors and physical characteristics that allow organisms to live successfully in their environments.

Answer to Ignitor-question 2
• All animals live in habitats. Habitats provide food, water, and shelter which animals need to survive, but there is more to survival than just the habitat. Animals also depend on their physical features to help them obtain food, keep safe, build homes, withstand weather, and attract mates. These physical features are called physical adaptations. Physical adaptations do not develop during an animal's life but over many generations. The shape of a bird's beak, the number of fingers, color of the fur, the thickness or thinness of the fur, the shape of the nose or ears are all examples of physical adaptations which help different animals to survive.

Directions For Lesson
• Complete the organizer during the slide show presentation for all the animals given.
Species adaptation How this adaptation helps the animal survive
ie. butterfly
camouflage Helps animal elude its prey by blending in with its environment

• DESCRIPTION: The East African Hedgehog can be distinguished from all other species of hedgehogs because it lacks a hallux (1st toe) and thus has only 4 toes on the hind foot. It also is smaller than the European hedgehog. They are covered dorsally with a uniform coat of spines (modified hairs) which have alternate light and dark color rings.

• Camels are well known for their humps. They do not, however, store water in them as is commonly believed, though they do serve this purpose through roundabout means. Their humps are a reservoir of fatty tissue, while water is stored in their blood. However, when this tissue is metabolised, it is not only a source of energy, but yields through reaction with oxygen from the air 1111 g of water per 1000 g of fat. This allows them to survive without water for about two weeks, and without food for up to a month.

Independent Task
• Use your adaptation organizer to design your own ‘Super Animal’. This animal should not be a ‘real’ animal and should include at least five adaptations that were mentioned during the slide show. You may create new adaptations when creating your ‘Super Animal’.

‘Super Animal’ Rubric
• 1)include at least five adaptations included in the slide show presentation
• 2)label each adaptation and describe what the adaptation is used for
• 3)color your ‘Super Animal’ diagram the appropriate colors
• 4)create an ecosystem that would support your ‘Super Animal’-add color!
