Grade 3 Science

Course Description

Semester A

Third grade science introduces students to experimentation as they journey through the earth and its many miracles.  They will begin by learning about the earth, the sun and the moon.  By participating in simple experiments students will explore the water cycle, gravity, the weather and it’s patterns, various types of terrain, and the role of plants in the production of oxygen and their importance to human survival.  Learners will expand their knowledge through video, pictures, short readings, projects, and hands on experiments.  Learners will understand that experiments require the use of instruments, observation, recording, and drawing evidence based conclusions.  Grade 3 science provides students with the opportunity to expand their minds and see for themselves the way that science is a part of their everyday lives.

Semester B

Semester B of third grade science begins with the students writing a poem about the seasonal cycles.  The learners continue with root formation, the interdependence of plants and humans, biomes of land and sea, extreme weather, rocks, vertebrates and invertebrates, as well as extinction.  All of these lessons are taught using video, projects, and experimentation.  Semester B asks learners to look a bit deeper into things they encounter such as the ocean and weather.
