Materials You Provide

  • pencils (1 per student, for paper version)
  • computer with an Internet connection (1 per student, for online version)

Resources Provided


Print one copy of the 1.1 Plants Unit Pretest for each student. If you are administering the pretest on the computer, prepare one computer with an Internet connection per student.


1. Describe the unit pretest.

Explain the purpose of the unit pretest to students:

  • It will help you as a teacher understand how students think about what happens when plants grow.
  • It will help them think about what they know and what questions they have.


Use the 1.1 Plants Unit Pretest to assess students' understanding of photosynthesis, cellular respiration, and biosynthesis in terms of learning progression levels. You should not give your students grades on the pretest or expect your students to know the correct answers. The document 1.1 Assessing Plants Unit Pretest has assessment guidelines, identifies correct responses, and explains how students’ responses reveal their learning progression levels.
