• Cup Design Round 1 Build:

  • Group size: 2-3

  • Setup: Arrange cup design materials in a central location accessible to all students. These materials should include: 10 - 16 oz single wall plastic cups, 10 plastic lids, aluminum foil, plastic wrap, sheets of foam and/or felt, plastic straws, cotton balls, paper towels, cardboard wrap, paper cups, paint and paint brushes, rubberbands, tape, glue and/or hot glue. Students may add materials they bring from home.

  • Safety: If hot glue is used, warn students not to touch the tip of the glue gun and to be careful when they handle it. They should carefully return the glue gun to the table top when finished. Students need to be careful when handling parts of the cup until the hot glue has cooled.

• Cup Design Round 1 Tests

  • Group size: 2-3 

  • Prior to testing, make ice to chill water. You will need to chill at least 400 mL of water for each group of students, so make the appropriate amount of ice.

  • Prepare design testing bins for each group that include: 1 500-mL graduated cylinder or beaker, 1 thermometer, 1 timer or stopwatch, 1 12-inch ruler, and 1 lamp with 100-watt bulb.

  • Safety: Warn students not to touch or handle the lamps during the bright light test. Lamp shields can become very hot during the investigation and the light bulbs are also breakable. Lamps should not be removed until they have cooled completely.
