5. Welcome Scientists! • Record your homework • See Mrs. Grgurina to get your homework checked. • QUIETLY read at your desk or work on another assignment.

6. Welcome Scientists! • Record your homework • Keep your homework on your desk so I can check it!

7. Learning Paths • Read all directions on your learning path carefully. 1st)INTRODUCTION choice activities 2nd) Complete PRACTICE/EXPLORATION choice activities 3rd) Complete Assessment or Extension Activities **Ready for fruit loops??? You need to complete all sheets first, then see me to get your cereal.**

8. States of Matter Record the title in your notebook. Be sure to read ALL slides carefully and only take notes on information that is in blue print.

9. States of Matter We already know that matter is anything that has a MASS and a VOLUME. But if we were to sort ALL of the matter in the world into just three categories, how could we do it???

10. States of Matter The three states of matter are… • SOLID • LIQUID • GAS

11. States of Matter Each type of matter is made of particles/atoms and they look different from each other. Can you identify which of the following belongs to a SOLID, LIQUID, AND GAS? Be sure to have a reason WHY! Record your thoughts in your notebook! 1. 2. 3.

12. ANSWERS! 1. GAS 2. SOLID 3. LIQUID

13. SOLID MATTER Solid Matter: • atoms are packed close together (more dense) • has a definite volume and shape (don’t change shape or space it fills) • atoms vibrate a little, but not too much! DRAW THIS EXAMPLE!

14. THINK ABOUT IT!!! Consider a rock and how its size and shape stay the same, regardless of where you put it. You can break it, but it is still made of solid rock particles.

15. SOLID MATTER What types of items do you think are solid matter? Brainstorm a list in your notebook!

16. SOLID MATTER All of these solid examples below have a definite shape and volume. Be sure to have at least three of these examples in your notebook:

17. LIQUID MATTER Liquid Matter: • has a definite volume (will always fill same amount of space) • can change shape by flowing (takes shape of any container) • atoms/molecules touch and can move around DRAW THIS EXAMPLE!

18. THINK ABOUT IT!!! Consider 8 ounces of milk. Its volume stays the same, whether you put it in a saucer for the cat to drink or in a glass for yourself; but its shape changes to match the shape of the container.

19. LIQUID MATTER What types of items do you think are liquid matter? Brainstorm a list in your notebook!

20. LIQUID MATTER All of these liquid examples below can change shape, but volume always stays the same! Be sure to have at least three of these examples in your notebook:

21. GAS MATTER Gas Matter: • no definite volume or shape (can change!) • can spread out forever OR take shape of container • have the most energy! • particles do not touch and have low density (light) DRAW THIS EXAMPLE!

22. THINK ABOUT IT!!! Consider a sample of air. It will fill an empty room, a balloon, a tire, or a rubber raft. Its shape and volume change to the shape and volume of the container in which it is placed.

23. GAS MATTER What types of items do you think are gas matter? Brainstorm a list in your notebook!

24. GAS MATTER All of these gas examples below can change its shape and volume! Be sure to have at least three of these examples in your notebook: Helium gas in the sun Air in a bike tire

25. Change in Temperature But what do you think happens to the atoms in matter when they are heated or cooled??? Do any changes happen?

26. Change in Temperature *Temperature affects the atom’s energy levels!

27. Change in Temperature Think about it… When you are hot, you normally don’t want anyone near you. You want to move far away from other people so you don’t feel as hot. When you are cold, you want to get close and huddle with others to stay warm!

28. Change in Temperature • Heated atoms gain energy and vibrate fast and expand (move apart/more space) • Cooled atoms, lose energy and vibrate slower and contract (shrink/get closer)

29. Change in Temperature Think about a thermometer! As it gets hotter, the liquid’s molecules inside the thermometer gain energy and expand. Its volume increases (taking up more space).

30. Matter – Changes of State

31. Change in Temperature This happens to atoms in ALL states of matter-solids, liquids, and gases. • What do you think would happen to any material if the temperature suddenly decreases from 70ºF to 30ºF? a. Expand because the molecules are gaining energy and moving faster b. Expand because the molecules are losing energy and moving slower c. Contract because the molecules are gaining energy and moving faster d. contract because the molecules are losing energy and moving slower

32. Change in Temperature • What do you think would happen to any material if the temperature suddenly decreases from 70ºF to 30ºF? a. Expand because the molecules are gaining energy and moving faster b. Expand because the molecules are losing energy and moving slower c. Contract because the molecules are gaining energy and moving faster d. contract because the molecules are losing energy and moving slower

33. Finished??? • Be sure to have recorded all important notes that were in blue print. I will be checking notes and talking to you about what you have learned. • You may choose an option from Introduction B column.
