A student placed two batteries in a flashlight in the order shown in the picture. The flashlight will not turn on. Based on the evidence observed, what is the best explanation as to why the flashlight will NOT turn on?

• F. The bulb is burned out.

• G. The batteries are old.

• H. The arrangement of the batteries does not allow a complete circuit.

• J. The arrangement of the batteries allows for a complete circuit.

A student observes a hotplate on a table. The hotplate has an on/off switch and a dial to control the temperature. The hotplate is not in use now, but will be used in the science class investigation on the electrical circuits. In order to use the hotplate during a science investigation, what must the student do to the hotplate to complete the circuit?

• A. Plug the hotplate into the outlet.

• B. Turn the switch to the "on" position.

• C. Plug in the hotplate, and place a beaker on the plate.

• D. Plug in the hotplate, and turn the switch to the "on" position.

Which two objects use electrical energy to move an object?

• F. A fan and a pencil sharpener

• G. A radio and a stove

• H. A lamp and a television

• J. A camera and an MP3 player

A student is investigating how temperature affects the mass of a ball of clay. She will record the mass of the clay, place it in the freezer for 15 minutes, and measure the mass of the clay again. She will repeat the investigation every 15 minutes for a total of two hours. Which tool will the student need to complete the investigation?

• A. Thermometer

• B. Gloves

• C. Spring scale

• D. Triple-beam balance
