−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).

−==Developmental Questions (What discussion questions)==
−# why we have to wrap shoe box with black paper?
−# can we use black paint insted of balck paper?
−
−==Evaluation (Questions for assessment of the child)==
−# what is the role of black paper in this activity?
−# which is good for the solar cookoer -black paper or white paper?
