Second Grade Science

Grade 2 Science and Technology/Engineering Benchmarks

Earth and Space Science

  • Recognize that the sun supplies heat and light to the earth and is necessary for life.
    • Understand the use of solar energy in the formation of coal, oil and direct heat.
    • Understand that air is a mixture of gases that is all around us and that wind is moving air.
      • Describe weather changes from day to day and over the seasons.
      • Independently identify examples of water, rocks, soil and living organisms that are found on the earth’s surface.

Life Science

  • Classify  plants and animals as living things that grow, reproduce and need food/water/shelter.
    • Recognize that living things can be classified according to similar characteristics.
    • Recognize fossils and pictures of fossils. Understand that they provide us with information about living things that inhabited the earth years ago.
  • Recognize and define a habitat as a place in which a plant/animal lives. Give examples.
  • Identify the ways in which an organism’s habitat provides for its basic needs ( e.g., air, water, nutrients, light, and shelter).
  • Recognize that changes in habitat can affect plants and animals.

Physical Science

  • Demonstrate that the way to change the motion of an object is to apply a force (i.e. push or pull).
  • Understand that force affects motion.


  • Construct a habitat meeting criteria necessary to sustain life.

Skills of Inquiry/Scientific Process We Expect Students to Demonstrate
(from the MA Science and Technology/Engineering Framework, 2006)

  • Ask questions about objects, organisms, and events in the environment.
  • Answer the question, “Why?”  or “What would happen if…?”
  • Make predictions based on observed patterns.
  • Choose, name and use simple equipment and tools (e.g., rulers, thermometers, hand lenses, balance and meter sticks) to gather data and extend the senses.
  • Record observations and data with pictures, numbers, or written statement.
  • Discuss observations with others.
