2. Tuesday, 8/30 Day 1 Science Starters Sheet 1. Please have these Items on your desk. Agenda 2- Fill out your Agenda. Science starter : When water falls freely, why does it Spread out? What are water drops made of? (don’t say Hydrogen and Oxygen) Science notebook S.F. Topic Page Work Sheets

4. Table of Contents Update O Pg. 23 8/30 Chemistry Learning Goals O Pg. 27 8/30 Cohesion & Adhesion W.S. O Pg. 28 8/30 Water Olympics closure W.S.

5. White boarding O What can we measure about stuff? O List at least 8 properties of water (ex.-wet, colorless, etc.)

6. Table of Contents Update O Page 30 8/30 Matter Grid Page 31 8/24 Matter Notes (Cornell style)

7. MATTER Pure Substances Mixtures ElementsCompoundsHeterogeneousHomogeneous Particle:AtomEx: O, H, Na, C Particle:MoleculeEx: H 2 O, NaCl, CO 2 Parts not visible, evenly mixed Ex: Salt water, air,coffee Visibly different parts Ex: Salt + pepper, Water + sand

8. What does the word molecule mean? https://www.youtube.com/watch?v=guoU_c uR8EE

9. Matter: It’s what the world is made of.

10. What is matter? O Matter is anything that has mass and takes up space.

11. What do you know about matter? Solids Liquids Gases Plasma

12. Solids O Solids have definite shape and definite volume. O Solids have mass. O Solids take up space. O Objects don’t pass through easily. Read more!

13. Particles in Solids: O Are packed tightly together O Have very little energy O Vibrate in place

14. Liquids O Liquids take the shape of their container and have definite volume. O Liquids have mass. O Liquids take up space. O Liquids have surface tension. Read more!

15. Particles in Liquids: O Are loosely packed O Have medium energy levels O Particles flow around each other

16. Gases O Gases spread out to fill the entire space given and do not have definite volume. O Gases have mass. O Gases take up space. Read more!

17. Particles in Gases: O Move freely O Have LOTS of energy

18. Plasma O Lightning is a plasma. O Used in fluorescent light bulbs and Neon lights. O Plasma is a lot like a gas, but the particles are electrically charged. O Plasma can flow like a liquid.

19. Particles in Plasma: O Are electrically charged O Have EXTREMELY high energy levels

20. STATES of matter? What would it take for matter to move from one state to another?

21. Energy determines the state!

22. Add or Subtract Energy... When energy is added, particles move faster! When energy is taken away, particles move slower!

23. What will happen? Why?

24. Solid + Energy = ? O When energy is added to solids, they become liquids! O Examples?

25. Liquid + Energy = ? O When energy is added to liquids, they become gases! O What examples can you think of?

26. Changing States O There are several names for matter changing states: O State change O Phase change O Physical change

27. So, did we get something new? O Ice cream and melted ice cream? O Chocolate and melted chocolate? O Ice, water, and water vapor? O Steel and molten steel?

28. Review Questions 1. What state of matter has definite volume and definite shape? 2. Describe the properties of liquids. 3. Describe the differences between gases and plasma. 4. What is needed for states of matter to change phase?

29. Tuesday, 8/30 Day 2 Science Starters Sheet 1. Please have these Items on your desk. Agenda 2- Fill out your Agenda. 3.Science Starter: States of Matter- One of four forms, Solid, Liquid, gas or plasma-in which matter exists. Liquid- A state of matter that has no definite shape but has a definite volume. Science notebook
