Today we will begin a study of heat and its properties. Put two drops of food coloring in each container of water. The measure of the speed of particles is called temperature. Use a thermometer to find the temperature of a bowl of cold tap water, hot tap water, crushed ice and boiling water. Record and discuss the temperature differences.
Heat moves through solids by conduction.
Use a heavy candle in a holder. You light the large candle, then, light the small candle in the flame of the big candle. Drop spots of the melted wax from the small candle onto the large nail making a row of wax. Use the clothespin to hold the end of the nail in the flame of the large candle. Observe what happens.
