1. 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 helps the can absorb
  −
heat.
  −
<br>2. Use kabob stick to punch a hole through
  −
one of the long sides of the shoebox. The
  −
hole should be about 2” from the back of the
  −
box. 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. Insert the
  −
thermometer, and record the temperature. record the temperature
  −
again at regular intervals (15 minutes or more).
