Activator

• You and a partner will compete in the great ice cube race to see who can melt an ice cube in a zip lock bag the fastest.

• You may not leave your area or take the ice cube out of the bag.

• Write as your activator how you win the race.

Heating Curve of water

• You will be given a beaker with ice water and a thermometer.

• When told to start read and record the temperature on your data table.

• Stop after your ice melts and bring your water to the front of the class.
