Presentation Transcript

  1. Catalyst • In your journal, respond to the following question: Would it be a good idea to inflate my road bike tires to high pressures in Los Angeles during the summer? Why or why not? Think CHEMISTRY!

  2. Pressure Stations! • Groups of 4 (we will number off) • Each station has an activity and 2-3 journal questions that you are responsible for. • Your exit ticket today is your individual journal responses. I will be checking these before you leave today.

  3. Lecture 6.2 – Pressure Effects

  4. Learning Target (Review) • LT 6.1 – I can explain how pressure is created through the collisions of molecules with a surface.

  5. I. Pressure vs. Temperature • Thermal energy – energy that is related to temperature. • Pressure increases with increasing thermal energy.

  6. II. Pressure vs. # of Molecules • Pressure increases with the # of gas molecules…why? • More molecules = more collisions

  7. III. Pressure vs. Altitude • Pressure decreases with altitude (as we go higher up in the atmosphere)…why??? • Gravity • Temperature decreases

  8. IV. Pressure vs. Depth • Pressure increases with depth (below the surface of the ocean)…why? • Weight of water creates pressure • Dolphin Kid, Son of Aquaman

  9. Label It! • In your journal, please label your station activities as either: pressure vs. temperature, pressure vs. # of molecules, pressure vs. altitude, or pressure vs. depth. • This is your exit ticket for today and your journal will be graded!

  10. Closing Time • Homework: HW6.1 set due Thursday/Friday. This will be graded! • Binder tabs, binder, and notebook are required.
