As the site describes it, this resource is "These are NOT interactive, on-line lessons, but rather may be printed for use with prospective and practicing K - 8 teachers. Each lesson has six parts, including a biology lesson, knowledge mapping exercise, and glossary for students and for teachers, a teachers' guide for both the biology lesson and knowledge mapping exercise, and a table of persistent alternative ideas."


1. What are cells made of?

2. Dynamic Cell Simulation Introduction

3. Simulation Set-UP

4. Harvesting Energy from Glucose in the Mitochondrion

5. Reading the Genetic Code in the Nucleus

6. Preparing tRNAs for Protein Synthesis

7. Protein Synthesis on the Ribosome

8. Connections and Review

OBJECTIVES Once you have completed these exercises you should be able to:

1. Explain and apply cell theory.

2. Describe the appearance and function of the major components of a cell, including: cell membrane, cytoplasm, and the following membrane-bound organelles: nucleus, rough and smooth endoplasmic reticulum, mitochondria, chloroplast, and vacuole.

3. Describe the appearance and function of some subcellular structures, including ribosomes.

4. Describe how respiration supports protein synthesis which includes copying of DNA into RNA (transcription) and translation of RNA into protein (see Figure 1).

5. Understand the roles of some important enzymes and macromolecules in protein synthesis, including RNA polymerase, transfer RNA, messenger RNA, and ribosomes.
