Objectives

In this unit, students will learn that everything around us is made of matter. Students will:

  • define solids, liquids, and gases and identify these based on particle activity.

  • explain the difference between volume and mass.

  • understand the concepts of physical and chemical change and apply knowledge of these concepts to real-life examples.

  • understand the concept of pure substances and mixtures and apply knowledge of these concepts to real-life examples.

  • define and categorize physical and chemical properties.

  • identify a closed system.

  • define the law of conservation of mass and provide examples of how mass is conserved.

    Performance Assessment:

    States of Matter Matching Card Game

    Each student will be given a worksheet with thirty squares, each containing information about one state of matter. Students will also be given a pile of picture cards, each representing either a gas, solid, or liquid state of matter. Each student will be required to match all picture cards with each of the thirty information boxes on the worksheet by placing one picture card over the information that matches its picture. Print outs and templates are available below. Each student will receive the following:

    • State of Matter Picture cards (x40 per student.*There will be extra.)

    • Matter Information Worksheet (x1)
