Put the children's names on the horizontal axis and the temperature range on the vertical axis. Ask each child to come to the graph and write the temperature they recorded. Children find the temperature range in the area by finding the minimum and maximum temperatures that the children recorded. Children work out the average temperature recorded by adding together all the temperatures and dividing them by the number of temperatures. Mark the average temperature on the graph as a line.
Children discuss the reasons for any variations.
Have the children take the temperatures on other days and in different seasons and compare the findings. Email other children from school around the world and compare your findings with those in other parts of the world. Record these on a world map. Children look at the map of the Bermuda Triangle from Places of Mystery . They enlarge the map using the activity sheet here .
