Learning Objective

Students will be able to explore adaptations for survival.

Today's Lesson

In this lesson, we'll explore adaptations for survival. Scientific inquiry allows us to investigate and explain natural phenomena.

An adaptation is a characteristic that helps an organism survive and reproduce in its environment. Adaptations can be physical (like a polar bear's thick fur for cold) or behavioral (like birds migrating south for winter). Adaptations develop over many generations through natural selection—organisms with helpful traits are more likely to survive and pass those traits to offspring. Every organism has adaptations that match its habitat. Adaptations show how life has changed and diversified over time!

As you work through today's material, pay attention to the examples and try to identify the patterns or strategies being used. This will help you apply these concepts to new problems.

Take notes on key points and make connections to what you've already learned in previous lessons.
