With temperatures dropping, it is a perfect time for children to expand their knowledge and awareness of winter weather. Take this winter season as an opportunity to do an investigative study of the weather with the children. Collect and measure the amount of falling snow in a snow gauge. You can construct a snow gauge out of the bottom half of a clear plastic soda bottle. Make distinct demarcations on the outside with which to take measurements.
Take different measurements at different points (i.e. under a tree, by your door, in the middle of the preschool playground) and record your findings and then discuss them with the children. Compare the different amounts of snow versus the different places they were collected. With this activity the children will be developing math skills through learning the concepts of measurements, numbers, and time. They will also increase their knowledge of science by learning winter weather systems and through the observation and description of their findings at the snow gauges.
