Sun, Heat, Air and Wind: weather instruments, wind speed and direction

A curious pre-school child asks questions to a big kid about how weather works. Every answer is enlightening yet leads to another question. The little child learns that wind is air that moves, that may be gentle or strong and even continue at night. Wind can do work for people, making our lives easier. The big kid explains how our bodies sense wind and how meteorologists use weather instruments to determine wind speed and direction. At the end of the program the pre-school child surprises the big kid by summarizing everything he learned and reciting the principle that the sun sends heat to Earth which makes air move as wind. The moral of the story is asking questions makes us smarter.
