MORE ABOUT AIR MOVEMENTS
MUST BE DONE WITH ADULT SUPERVISION! What are some of the things that make air move? What are some things that determine the direction in which air will move? Let's fool around with it a bit and see if we can find some answers. Blow some soap bubbles or bring a burning candle flame near a hot radiator or heater. Observe the movement when the bubbles or flames are placed in different positions. You will notice that the air above the radiator seems to travel upward, while the air near the floor moves toward the base of the radiator. Similarly, the bubbles or flames can be brought near an open window to see which way the air moves. If observations are coupled with temperature measurements, you will find that hot air tends to rise and cold air tends to fall. (Note: The air movement detector can also be used in this activity.)
