Grade 3/4 students have been exploring heat through a range of student designed experiments. A simple initial experiment saw them measure the changing temperature in a glass of warm and cold water. Using the same thermometer, type of cup and amount of water they discussed the only variable being the initial water temperature.
Following this experiment students designed their own simple experiment. They could change only one variable. Experiments carried out changed the shape of the cup, placed a cup outside or put a cup inside a container of water. Students also learned to create a control sample as a means of comparison. Data was recorded and conclusions were formed.
