Begin the lesson by observing a photograph of a cheetah family. Discuss the visible similarities between the parents and their offspring, introducing the concept of traits.

Heredity and Traits
Learning Objectives
- Identify similarities in traits between cheetah parents and their offspring.
- Explain the concept of traits and how they are inherited from parents.
- Describe how heredity is responsible for passing traits from parents to offspring.
- Understand the role of genes in determining inherited traits.
- Recognize that both plants and animals inherit traits from their parents.
Introduction and Hook
Engage students by asking them to think about traits they share with their own family members, setting the stage for a discussion on heredity.
Direct Instruction
Explain the concept of traits and heredity using examples from both animal and plant kingdoms. Highlight how traits are passed from parents to offspring through genes.
Introduce the role of genes in determining inherited traits with relatable examples, such as eye color and plant leaf shapes.
Guided Exploration
Watch the video 'Survival of the Fittest' to understand how advantageous traits help organisms survive and reproduce. This video illustrates natural selection using examples like cheetahs and penguins.
Facilitate a discussion on how traits observed in the video relate to the concept of heredity and survival.
Hands-On Activity
Conduct an activity where students classify traits they observe in various plants and animals, determining which traits are inherited.
Use the 'Inherited Traits in Animals' assessment to reinforce the understanding of traits passed from parents to offspring.
Independent Practice
Assign students to create a family trait chart, identifying traits they share with family members and explaining the concept of heredity.
Check for Understanding
Use the 'Inheritance and Variation' assessment to evaluate students' understanding of genetic similarities and differences.
Review and Reflection
Encourage students to reflect on their learning by discussing how understanding heredity can help explain the diversity of life on Earth.
Assessment and Extension
Administer the 'What Are Your Inherited Traits?' assessment to gauge students' grasp of heredity and genetic traits.
Encourage further exploration by inviting students to research how environmental factors can influence traits, using the 'Environmental Traits' assessment.
Conclude with a quiz to test comprehension of the unit on Inheritance and Traits.
