A student filled four different bowls with 10 ice cubes in each. Each bowl was the same size and shape. The student timed how long it took all the ice cubes in each bowl to melt. The results are shown.

Based on these data, what should the student conclude?

• The metal bowl is the best conductor.

• The plastic bowl is the most flexible.

• The clay bowl is the hardest bowl.

• The glass bowl is easiest to break.

Cell phones can be plugged into a wall electrical outlet or they can use batteries inside the phone. How can both work for a cell phone?

• Both wall outlets and batteries provide a source of electrical energy.

• Cell phones have transformers that don't need electrical energy.

• Batteries are used to charge electrical wall outlets.

• Electrical outlets and batteries are both smaller than the cell phone.

Which statement is true about the picture?

• The metal pan causes the water to boil rapidly.

• The metal pan is a poor conductor of thermal energy.

• The wooden handle is a good insulator of thermal energy.

• The wooden handle is a good conductor of thermal energy.
