This activity packet follows the Harcourt School Publishers Science series for Chapter 3- Adaptations. I created this packet to follow along with the different sections of the chapter and also as a study guide for students. The packet starts off with students scanning QR codes to discover the vocabulary terms for the unit. After scanning the code, they can write down the terms and then define them using the glossary of the textbook. This packet will cover all three sections of Chapter 3. There is no answer key included in this purchase, however many of the answers to the questions can be found in the margins of the teachers manual.
