How do you know when milk has gone bad? • 2. How do you know when a nail has rusted? • 3. How do you know when your food is burnt?

  2. 8th Grade Science Today’s Schedule Monday, January 28, 2013 Do Now Foldable Physical and Chemical Changes Reading Frayer Model Project Essential Question Vocabulary How do we describe and classify matter? What happens to atoms in a chemical reaction? Electron Proton Neutron Electron Cloud Electrical Charge Valence Electron Nucleus Reactivity

  3. 8th Grade Science Today we will… Monday, January 28, 2013 8.5(E)  investigate how evidence of chemical reactions indicate that new substances with different properties are formed Objective: Students will identify chemical changes in their everyday life and describe the difference between physical and chemical changes

  4. 8th Grade Science Foldable Monday, January 28, 2013 • Fold pages 33 and 35 towards each other. • Cut each page in half

  5. 8th Grade Science Foldable Monday, January 28, 2013 Physical Properties Chemical Properties • Label each foldable flap Chemical Changes Physical Changes

  6. 8th Grade Science Foldable Monday, January 28, 2013 Describe 3 examples • 1. Write a definition for physical properties • 2. Describe 3 examples of physical properties • 3. Repeat with chemical properties. • *Use Reading on page 27/28 of INB as guide* Chemical Properties Write definition Chemical Changes Physical Changes

  7. 8th Grade Science Foldable Monday, January 28, 2013 Physical Properties Chemical Properties • Return to front and add pictures to physical and chemical properties Chemical Changes Physical Changes

  8. 8th Grade Science Physical and Chemical Changes Monday, January 28, 2013 • 1. Read “Physical and Chemical Changes” • 2. With a partner, complete the Frayer Model for Physical and Chemical Changes. Physical Changes Chemical Changes

  9. 8th Grade Science Brain-Pop Video Monday, January 28, 2013 • Physical and Chemical Changes

  10. 8th Grade Science Do Now Tuesday, January 29, 2013 • Read the Chemistry story at your table. • On your “Do Now” page, answer the following questions. • List 2 examples of physical properties in this story. • List 2 examples of chemical properties in this story • List 2 examples of physical changes in this story. • List 2 examples of chemical changes in this story.

  11. 8th Grade Science Today’s Schedule Tuesday, January 29, 2013 Do Now Marshmallow Man Lab Finish Foldable Essential Question Vocabulary How do we describe and classify matter? What happens to atoms in a chemical reaction? Electron Proton Neutron Electron Cloud Electrical Charge Valence Electron Nucleus Reactivity

  12. 8th Grade Science Today we will… Tuesday, January 22, 2013 8.5(E)  investigate how evidence of chemical reactions indicate that new substances with different properties are formed Objective: Identify examples of chemical and physical changes.

  13. Making your Marshmallow Man This sounds fun! • 1. Insert a toothpick halfway into the flat side of one marshmallow to form the body. • 2. Stick the second marshmallow on the remaining end of the toothpick. • 3. Insert four toothpicks into opposite sides of the body to make his arms and legs. • 4. Place a marshmallow on a toothpick and stick half of the toothpick in the body to make the head.

  14. Action #1 = Pull Pull my arm! • 1. Pull the left arm of Marvin. • 2. Observations: Describe what happens when you pull the marshmallow arm of Marvin.

  15. Action #2 – Chew • 1. Take off Marvin’s right arm and chew it. • 2. Observations: What forces are you placing on the marshmallow as you chew? • ***REMEMBER: Only • record observations • about your CHEWING, • not swallowing. Chomp chomp!

  16. Action #3 – Digest I’m yummy! • Take Marvin’s left leg and digest it. • Observations: What is happening as you are digesting Marvin’s leg?

  17. Action #4 – Pound OUCH! • Pound the center of Marvin’s body. • Observations: What force(s) are you applying to Marvin and how is it changing his appearance?

  18. Action #5 – Puncture But I already have three holes in my head! • Puncture a hole through Marvin’s head. • Observations: What force(s) did you apply here and how did the marshmallow head react?

  19. Action #6 – Amputate and Boil • Amputate (cut off) Marvin’s right leg and carefully place it in the boiling water. • Observations: How does the boiling water change Marvin’s leg? It’s HOT in here!!!

  20. 8th Grade Science Foldable Tuesday, January 29, 2013 • Finish Conclusion Questions on Marshmallow Lab • Write a definition for physical changes • Describe 3 examples of physical changes • Repeat with chemical changes. • *Use Reading on page 31 of INB as guide* Physical Properties Chemical Properties Describe 3 examples Chemical Changes Write definition
