Paint a soda can black paint . If you don’t have paint you can use a felt marker − , or even wrap the − can with black paper. Secure the paper with tape or rubber bands.

This is for the thermometer. − <br>3. You may have to add several layers of − cardboard inside. This lets the thermometer reach the inside of the can. It also adds − insulation. Try wrapping the cardboard with aluminum foil to reflect heat onto the can. − <br>4. Attach another reflector with tape. Puncture the reflectors with kabob sticks, and − and slide them through the reflectors. use the sticks − to hold the reflectors open. − <br>5. Try using a black-painted can and a plain can to see how − fast each heats up. Make a chart to record your results. − <br>6. Lay the shoebox on its side in the sun. You can lean it against a wall to face the − sun. Fill the soda can about 3/4 full with water, and place it in the box.
