Convection is one of those words that we often hear used, but we may not completely understand its meaning. Weather forecasters show how convection currents are formed when warm and cold air masses meet in the atmosphere. Convection currents are responsible for warm water currents that occur in oceans. This activity demonstrates convection currents in a very colorful fashion.
How many breaths does it take to inflate an 2 meter (8 ft) Windbag? 70 breaths, maybe? Why even try? With a simple science secret you can amaze your students and friends by blowing up your Windbag in one breath! If you don’t believe it, try this amazing science activity! Windbags are so light and strong that even the smallest scientist can demonstrate the amazing properties of air!
