Did you know Whales were land animals?

Open Ended

What caused whales to change from land animals to water animals? Please provide detail. You have 5 mins.

Giraffe long necks

Discuss why the giraffes necks evolved.

Interesting fact: When you bend down for a long time and stand you feel dizzy. Giraffes dont have this problem because their brains are like sponges and retain blood. Even the giraffe brain had to evolve for them to be tall!!!!!

Multiple Choice

Which of the following is true about the picture above?

• Camels are highly adapted to cold climates.

Multiple Choice

Why is the mouse population changing over time?
