10.27 D3 Ktm And States Of Matter Intro

  1. 1. Day 3: October 27/28 <ul><li>Objective: SWBAT use the Kinetic Theory model to illustrate and account for the physical properties of a substance </li></ul><ul><li>Homework: page 38 </li></ul><ul><li>Warm up: What is the smallest thing that humans are made of? </li></ul>
  2. 2. Write in homework NOW <ul><li>turn to page 38 </li></ul><ul><li>Create your own example to explain the kinetic theory of matter. You must detail how it represents the movement of particles and the changes with more/less energy </li></ul>
  3. 3. Agenda <ul><li>Check Phys/Chem property homework </li></ul><ul><li>Grade discussion </li></ul><ul><li>Kinetic Theory of Matter </li></ul><ul><li>States of Matter foldable </li></ul><ul><li>Quizdom ---- lots!!! </li></ul>
  4. 4. Phys/Chem Homework pg 34 <ul><li>The water on the stove starts to boil </li></ul><ul><ul><li>Physical </li></ul></ul><ul><ul><li>Change of state </li></ul></ul><ul><li>The glow stick is snapped and starts to glow. </li></ul><ul><ul><li>Chemical </li></ul></ul><ul><ul><li>Gives off light </li></ul></ul>
  5. 5. Phys/Chem Homework pg 34 <ul><li>My hat is Carolina Blue. </li></ul><ul><ul><li>Physical </li></ul></ul><ul><ul><li>Color </li></ul></ul><ul><li>The dry ice is changing rapidly from solid to gas </li></ul><ul><ul><li>Physical </li></ul></ul><ul><ul><li>Change of state </li></ul></ul>
  6. 6. Phys/Chem Homework pg 34 <ul><li>When combined, the two clear liquids turn bright red. </li></ul><ul><ul><li>Chemical </li></ul></ul><ul><ul><li>Change of color </li></ul></ul><ul><li>An unknown rock is able to attract other pieces of metal </li></ul><ul><ul><li>Physical </li></ul></ul><ul><ul><li>Magnetism </li></ul></ul>
  7. 7. Phys/Chem Homework pg 34 <ul><li>The rock will not float in water </li></ul><ul><ul><li>Physical </li></ul></ul><ul><ul><li>Density </li></ul></ul><ul><li>Eric cuts the cheese into eight smaller pieces </li></ul><ul><ul><li>Physical </li></ul></ul><ul><ul><li>Change of shape </li></ul></ul>
  8. 8. Grades <ul><li>Summary: not good </li></ul><ul><li>* </li></ul>
  9. 9. Page 37: Kinetic Theory of Matter <ul><li>Label your page, watch our demonstration </li></ul><ul><li>After notes, you will have to write what the demonstration represented </li></ul>
  10. 10. Kinetic Theory of Matter Idea that explains A concept movement All stuff in the universe
  11. 11. Kinetic Theory of Matter <ul><li>All things are made up of small particles too small to be seen that are in constant motion </li></ul><ul><li>The more energy you have, the more motion you have </li></ul>
  12. 12. Thinking Questions <ul><li>What was added to the solid to cause it to melt? What would you take away from the system to make it re-solidify? </li></ul><ul><li>How is a liquid transformed into a gas? </li></ul><ul><li>How is a gas transformed into a liquid? </li></ul><ul><li>In the popcorn and margarine model, what does the margarine represent? What do the popcorn kernels represent? </li></ul>
  13. 13. Key Takeaways <ul><li>Popcorn = atoms </li></ul><ul><li>Butter = bonds between atoms </li></ul><ul><li>Exploding popcorn kernel = atoms going to gas phase </li></ul><ul><li>the atoms are always moving </li></ul><ul><li>the more energy they have the faster they move </li></ul><ul><li>When they get enough energy, the substance changes states of matter (i.e. liquid to gas) </li></ul>
  14. 14. Foldable <ul><li>Fold paper hot-dog style </li></ul><ul><li>Z-fold for three equal sections </li></ul><ul><li>Cut three flaps on one side </li></ul>
  15. 15. Label the boxes Gas Liquid Solid Gas Liquid Solid
  16. 16. Solid <ul><li>H 2 0 = ice </li></ul><ul><li>Short bonds, close together </li></ul><ul><li>Vibrate slightly, but not much movement </li></ul><ul><li>Density: High </li></ul><ul><li>Volume: Fixed </li></ul><ul><li>Surface area: Fixed </li></ul><ul><li>When heated: Expands Very little </li></ul><ul><li>Diffusion: Almost impossible </li></ul>
  17. 17. Liquid <ul><li>H 2 0 = water </li></ul><ul><li>Bonds: longer and looser </li></ul><ul><li>Movement: flexible, fluid (bend without breaking) </li></ul><ul><li>Density: High </li></ul><ul><li>Volume: Fixed volume </li></ul><ul><li>Surface area: Fixed </li></ul><ul><li>When heated: expands tiny bit </li></ul><ul><li>Diffusion: happens easily </li></ul>
  18. 18. Gas <ul><li>H 2 0 = steam, water vapor </li></ul><ul><li>Bonds: No bonds </li></ul><ul><li>Movement: random, all over, freely moving </li></ul><ul><li>Density: Low </li></ul><ul><li>Volume: Changing </li></ul><ul><li>Surface area: changing </li></ul><ul><li>When heated: expands A lot </li></ul><ul><li>Diffusion: happens really easily </li></ul>
  19. 19. Onto Page 39 <ul><li>Glue in the foldable on the top of page 39 so that it can fold out for studying </li></ul><ul><li>Decorate Front flap: Picture of each state of matter that makes sense to you </li></ul>
