Adaptations Glossary pg 105 WordDefinitionPicture AdaptationsA trait or characteristic that helps an organism survive. Internal Structures Traits or characteristics that are inside an organism. External Structures Traits or characteristics that are on the outside of an organism.
11
Create your own adaptation pg 104 Draw an animal that exists in the world today Describe a change in its environment that would require the animal to adapt. Draw the animal with its adaptation Describe how the new adaptation helps the animal to survive. The environment of this brown bear dropped in temperature causing snow and ice year-round. Over thousands of years, only the lighter colored bears survived causing the bear to adapt to a white environment.
12
DO NOW Date: 1/12 Name one internal structure that helps you to survive. What organ system is it part of?
13
ESSENTIAL QUESTION: What traits or characteristics provide an adaptive advantage for survival in some animals? OBJECTIVES: -Explore internal and external structures and how they provide an adaptive advantage for some animals.

DO NOW Date: 1/13 1/14 Reminders: Quiz Friday Notebook Check Friday What is an adaptation? What is an advantage?
19
ESSENTIAL QUESTION: How can traits change in a population over time? OBJECTIVES: -Explore how traits (or genes) are passed down from generation to generation and how that impacts the survival of a species.

Adaptations and Survival page106 Picture of the Adaptation Organism Describe the organism’s Environment Describe the Adaptation (structure/behavior) Is this structure INTERNAL or EXTERNAL? How does this adaptation enhance survival of the organism? FLOWER Flowers grow in fields and areas that are open. There is usually good rainfall in these areas. Bright Coloration (Structural) -Flowers have bright coloration that attracts bees. This is an external feature. The coloration of flowers attracts bees and sends signals to bees that there is pollen present. The bees are attracted to the flower and collect the pollen. When they land on other plants they pollinate those plants allowing the plant to reproduce.
