    • adjust it so the cover will cover it.

  • Make sure the thermometer is properly adjusted (short side of block ).

    • check adjustment without the styrofoam insulator beneath it.

  • Set up your test equipment

    • Place styrofoam insulator on the test stand

    • place can on the styrofoam.

    • Adjust insulation so the cover fits evenly over the top of the can.

  • Get water when instructed by the teacher.

    • transport in the double styrofoam cups with a meat tray cover to keep heat in.

  • Prepare a stopwatch.

  • Pour water into the test can when instructed to do so.

    • start the stopwatch

    • adjust so thermometer is centered and lower the cover.

    • put weights on the cover to keep it tight.
