Student Task

Student Task

Obtain two identical cardboard boxes (with folding lids) line one of the boxes internally with aluminium foils and avoid wrinkling the foil - it serves as the reflecting medium - place foil under the lid too and stand the lid up so that it can reflect sunlight into the box. When finished, obtain two identical beakers of the same amount of water each with a thermometer in the water and place these inside the boxes which themselves are placed outside on a sunny, warm day for say an hour of time. Record the temperature every 5 minutes for say a total of 1 hr and note the differences in temperature. You may try the same activity with different volumes of water.
