Bell Ringer: What is pressure?

• Quiz #3

  • Return and discuss chapter 2 tests

    • Retakes may occur before or after school, or during smart block

    • Last day for retakes is Wednesday, September 15

• 3.3 Notes

  • 3.3 Demos

    • Pressure

      • Balloon pops on one nail in a board, but not on the bed of nails because the force is spread over a bigger area, making less pressure

      • Mr. Bennett can lie on the bed of nails without being hurt because his weight is spread over a bigger area - less pressure
