Begin the lesson by introducing the concept of seed dispersal and its importance for plant growth. Discuss how seed dispersal helps plants grow in new places with less competition for resources.

Seed Dispersal
Learning Objectives
- Understand the concept of seed dispersal and its importance for plant growth.
- Identify different methods of seed dispersal, including wind, water, and animals.
- Recognize how certain seed characteristics aid in their dispersal by wind, water, or animals.
- Explain how animals contribute to seed dispersal through carrying or consuming seeds.
Introduction and Hook
Engage students with a question: 'How do you think seeds travel from one place to another?' Encourage them to share their ideas and experiences.
Direct Instruction
Explain the different methods of seed dispersal, including wind, water, and animals. Highlight how certain seed characteristics aid in their dispersal.
Use the video 'Seed Dispersal' to illustrate how seeds travel away from their parent plants. This video provides engaging demonstrations and examples of seed dispersal methods.
Guided Exploration
Facilitate a discussion on how animals contribute to seed dispersal. Encourage students to think about how animals might carry or consume seeds.
Watch the video 'All About Plants' to explore the diversity and adaptability of plants. This video supports understanding by illustrating how plants thrive in different environments.
Hands-On Activity
Conduct a hands-on activity where students create models of seeds that can be dispersed by wind, water, or animals. Encourage creativity and discussion about seed characteristics.
Use the 'Spread Some Seeds!' assessment to design a seed that can stick to clothing, simulating how seeds attach to animal fur. This activity encourages hands-on creation and reflection.
Independent Practice
Assign students to observe and record different types of seeds they find in their environment. Ask them to predict the method of dispersal for each seed.
Check for Understanding
Use the 'How Do Animals Disperse Seeds?' assessment to evaluate students' understanding of seed dispersal mechanisms. This activity encourages observational and inferential thinking.
Review and Reflection
Review the key concepts of seed dispersal with the class. Encourage students to reflect on how different methods of dispersal benefit plants.
Assessment and Extension
Administer the 'Review – Plants and Animals' assessment to test students' knowledge of plant needs and animal roles in seed dispersal.
Encourage students to take the unit quiz to assess their comprehension of the entire unit on plants and animals.
