Section Four- Evolution and Inheritance: Variation

Learning Objectives

• Understand why offspring look similar to their parents
• Define and explain variation
• Recognize the significance of variation in the world

What do you already know about offspring and their resemblance to their parents?

Inheritance of Characteristics from Parents

• Offspring inherit some features from their parents
• Resemblance between parents and offspring
• Introduction to the concept of inheritance

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
