Second Grade Lessons

Open each chapter to download the lesson plans and student activity sheets. Use the linked multimedia to help explain the science concepts to students.

  • Chapter 1 – Properties of Materials

    Students put objects and materials into groups based on their observable properties, test materials for strength and absorbency, and use their results to make a boat that can hold the most pennies before sinking.

  • Chapter 2 – Liquids have Properties

    Students use simple tests to compare the properties water, mineral oil, and Karo syrup (corn syrup) to see that different liquids have their own characteristic properties.

    • Lesson 2.1 - Liquids have properties image
      Lesson 2.1 - Liquids have properties

      Students do simple tests to observe the properties of water, mineral oil, and corn syrup on the surface of a zip-closing plastic bag to investigate the question: Can liquids that look similar have different properties?

  • Chapter 3 – Dissolving is a Property

    Students help develop a test to compare the dissolving of an M&M and a Skittle and see that the candy coating on both dissolve in a similar way but the insides dissolve differently.

    • Lesson 3.1 - Dissolving is a Property image
      Lesson 3.1 - Dissolving is a Property

      Students develop a test to compare the dissolving of an M&M and a Skittle in water to investigate the question: Do M&Ms and Skittles dissolve by the same amount?

  • Chapter 4 – Float and Sink

    Students test different materials to see if they float or sink and discover that certain materials, such as wax and wood, have the characteristic property of floating, and other materials, such as metal and rubber, have the characteristic property of sinking.

    • Lesson 4.1 - Float and Sink  image
      Lesson 4.1 - Float and Sink

      Students place small common objects made from wax, wood, metal, and rubber in water to investigate the question: Do certain materials tend to float or sink in water?

  • Chapter 5 – Heating and Cooling

    Students investigate the changes that result from heating and cooling a material like butter that can melt and solidify repeatedly, and the changes that occur when the ingredients in baking powder react which are not reversible.

  • Chapter 6 – Atoms

    Students use Snap Cubes to see that the same parts can be rearranged to make many different objects, and that these parts can be used as models of atoms that make many different molecules.
