Decomposers Lesson 5 Overview

Download PDF of Lesson 5 Teacher's Guide

Students use a scientific model to explain digestion and biosynthesis using the Three Questions.

Guiding Question

How do decomposers use food to grow?

Activities in this Lesson

• Activity 5.1: Tracing the Processes of Decomposers Growing: Digestion and Biosynthesis (40 min)
•  Activity 5.2: Molecular Models for Fungi Growing: Digestion and Biosynthesis (40 min)

Note: The molecular modeling part of Activity 5.2 is exactly the same as the molecular modeling for biosynthesis in the Plants and Animals units. Additionally, it is a 2-turtle activity which means it involves a higher level of complexity. Consider skipping the activity if you have already taught it in another unit or if it is too advanced for your class.

• Activity 5.3: Explaining How Fungi Grow: Digestion (40 min)
• Activity 5.4: Explaining How Fungi Grow: Biosynthesis (40 min)
