1. Changes in Matter Science Chapter 2 Grade 5

2. Chapter 2 – Vocabulary Physical Change Chemical Change Evaporation Condensation Sublimation Reactant Product Chemical Equation

3. Physical Change A change Matter keeps the same chemical properties A change in size, shape, volume, state of matter No new product

5. Chemical Change A change A matter changes into a different kind of matter New substance Different properties Light, heat, smell, color change are signs of chemical change

7. Evaporation Process Physical change Molecules spread out more Heat/ energy is added From liquid to gas (water to vapor) Opposite reaction to condensation

8. Condensation Process Physical change Molecules get closer together Heat/ energy is taken away From gas to liquid (vapor to water) Opposite reaction to evaporation Condensation forms clouds

10. Sublimation Process Physical change Molecules spread out Heat/ energy is added From solid directly to gas (dry ice to vapor)

11. Reactant A substance Used in a chemical reaction What you begin with The “problem” Reactants  Product A substance Made in a chemical reaction What you get in the end The “answer” Product

12. Chemical Equation Statement Chemical symbols Shows what happens in a chemical reaction Left side: Reactant Middle: Arrow Right side: Product
