Third Grade Science

About Grade 3 Science

Grade 3 science (3rd grade, ages 8–9) is 40 lessons in 5 units: Living Things (lessons 1–8), Earth & Space (lessons 9–16), Matter and Energy (lessons 17–24), Human Body & Health (lessons 25–32), and finally Science Projects (lessons 33–40), project work that brings the year together. Along the way, children learn to describe the four main stages of the water cycle in order, name the key components of a simple electric circuit and identify healthy exercise and fitness habits.

Start here: Lesson 1: Plant Life Cycles is free to open and print. Every other lesson has a free preview of its mini lesson and vocabulary.

Paper first: each lesson is printed before you call your child. You read it once and talk it through, your child does the exercises on paper, and you correct together with the Parent checklist — about 45 minutes at the table. The next day, a 10-minute screen review of the same lesson.
