In third grade, science moves out from the wings. Third grade science can be divided into two broad categories: science processes and science concepts. Some science processes include evidence, models, measurement, form and function, and explanation. Science concepts your child will learn this year include simple systems and subsystems; how sound is produced and how it travels; the characteristics, basic needs, and habitats of organisms; and forces that change the earth, such as earthquakes and glaciers.

Curriculum varies from state-to-state, but there are some key concepts commonly studied in third grade. Students working at the standard level at the beginning of third grade:

  • Observe and measure objects, organisms, and/or events
  • Classify objects, organisms, and/or events
  • Interpret graphs, charts, and tables
  • Plan and conduct a simple investigation
  • Communicate the results of a simple investigation

Students working at the standard level at the end of third grade:

  • Observe, record, and communicate changes
  • Measure length in centimeters, mass in grams, and temperature in degrees Celsius
  • Classify objects and organisms
  • Understand systems and subsystems
  • Explain how sound is produced and travels
  • Know the characteristics, basic needs, and habitats of organisms
  • Know how organisms fit together in a food chain
  • Understand how forces such as earthquakes, glaciers, volcanoes, and erosion change the earth
