  1. 1. CHANGES IN MATTER Grade 3 SY 2013-2014 By: Shirley Puaso- Valera
  2. 2. KEY QUESTIONS How does matter become beneficial to our everyday life?  Why it is important to understand the properties and the different types of matter? How can matter change?
  3. 3. OBJECTIVES Analyze how matter changes physically and chemically. Demonstrate ways on how matter undergoes changes in their properties.
  4. 4. Observe the changes that took place in the ice cubes.
  5. 5. THINK-PAIR-SHARE A. Work in pair (or group) and do the following activities. - tear a piece of paper - mold clay into different shapes - fold a handkerchief into two B. Observe on the materials while doing the activity. Ask them the changes that took place to the materials.
  6. 6. DISCUSSION
  7. 7. PHYSICAL CHANGES
  8. 8. PHYSICAL CHANGES IN MATTER A Physical change is a change in how matter looks, but not the kind of matter is it is.  Tear - Cut  Folded  Mixture  Solution - plates broken into pieces
  9. 9. DIFFERENT EXAMPLES OF PHYSICAL CHANGE 1. Ice becomes liquid when they are heated. This process of changing solid to liquid is called melting  Sublimation – is the process of changing solid matter to gas without passing the liquid state.
  10. 10. DIFFERENT EXAMPLES OF PHYSICAL CHANGE 2.Mothballs – undergo the process of sublimation once they are exposed to air.  Sublimation – is the process of changing solid matter to gas without passing the liquid state.
  11. 11. DIFFERENT EXAMPLES OF PHYSICAL CHANGE 3.When water is placed inside a freezer, it becomes ice. This process is called freezing. Some liquids, like oil and melted butter become hard and turn to solid when cooled. Freezing and cooling can change liquid to solid.Freezing is a change from liquid to solid at a constant temperature.
  12. 12. DIFFERENT EXAMPLES OF PHYSICAL CHANGE 4. When you boil water, you will observe water vapor or steam coming out of the container. Water vapor or steam is the gaseous phase of water. When we turns into water vapor, the water evaporates. Evaporation is the process of changing liquid to gas at a constant temperature or just below its boiling point.
  13. 13. DIFFERENT EXAMPLES OF PHYSICAL CHANGE 5. When you put some cold water in a drinking glass, droplets of water are formed outside of the glass. When vapor in the air touches a surface, it turns into liquid. This process of changing gas to liquid is called condensation.
