Carbon TIME Systems & Scale Unit: Read Me Document


The Animals Unit is a tool kit, not a script.

While the Animals Unit Teachers’ Guide may look like a script with lots of activities to do one after another, it is actually designed to be more like a user’s manual for a set of tools. You can decide which tools are right for your students and your goals. This document alerts you to choices to make before each lesson.

Making Your Choices

Here is a brief summary of choices for teaching Animals. See the Teacher’s Guides for more in depth discussions of your choices.

Lesson 1

All students should complete Lesson 1.

Lesson 2: Choose how to use repeating activities.

Activities 2.1, 2.2, and 2.3 are exactly the same as the equivalent activities in the Plants and Decomposers units. These are important and foundational activities, but students may not need to repeat them. Within Activity 2.1, the Cells: The Building Blocks Reading is optional.

Activity 2.4 is animal-specific, so we recommend teaching it.

Lesson 3

All students should complete Lesson 3.

Lesson 4: Choose how to use repeating Activity 4.1 and scaffolds in 4.2.

The molecular modeling part of Activity 4.1 is exactly the same as the molecular modeling for cellular respiration in the Plants and Decomposers units. Consider skipping the molecular modeling parts of the activity if you have already done them in another unit.

There are a set of scaffolding tools you can choose to use with your students in Activity 4.2, These tools include:

  • The Explanation Tool, which gives the students both more structured and less-structured ways to construct explanations that answer the Three Questions
  • The 4.2 Explaining How Cows Move and Function: Cellular Respiration PPT
  • The Three Questions Explanation Checklist, which students can use to evaluate their own explanations or other examples
  • Example explanations that students can analyze and discuss
  • A reading (4.2 How do Animals get the Energy They Need to Move? Reading), and a graphic organizer (Matter and Energy in Animals Graphic Organizer)

You may find that you use more of these scaffolds early on and gradually use fewer over time depending on your students’ needs. Use your professional judgement about the best choice for your students.

Lesson 5: Choose whether to use Activity 5.2 and scaffolds in 5.3 and 5.4.

The molecular modeling part of Activity 5.2 is exactly the same as the molecular modeling for biosynthesis in the Plants and Decomposers 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.

In Activities 5.3 and 5.4, you may choose from similar scaffolding tools listed for Activity 4.2.

Lesson 6: Choose how students will share their work in Activity 6.1 and which option students will complete in Activity 6.2.

Activity 6.1 engages students in reading about three different animals and explaining how they grow, move, and function. You probably don’t want every student to do a worksheet on all three animals, so there are several ways that students could become “experts” on one animal, then compare what they have learned: a jigsaw activity, working in groups to make posters, etc.

For Activity 6.2, students can compare flames and animal (6.2a) or develop a summary explanation that applies to all animals (6.2b). Both provide students with a review of the unit concepts in preparation for the posttest, so you should select one of the versions based on if you have previously taught Systems and Scale and your students' needs.

  • For Activity 6.2a, students will compare what they know about flames from the Systems and Scale Unit to what they have learned about animals in the Animals Unit.
  • For Activity 6.2b, students will work with partners or groups to complete the provided worksheet, make a poster, or make a PowerPoint presentation.
