Fascinating Experiments

Air Flow

Materials

  • A toy airplane
  • A chopstick
  • Fishing line
  • A clear container
  • Water
  • Food colouring

Procedure

  1. Fill the clear container with water.
  2. Use fishing line to attach the airplane to the chopstick, as if you were making a marionette.
  3. Suspend the airplane in the water and wait for it to stop moving.
  4. Carefully drop food colouring into the water over the wings, nose, etc.
  5. Observe and record what happens!

Suggestions for Art Activities

We could have spent all day watching the food colouring float through the water as we photographed this experiment! Students can create amazing drawings or paintings, based on the shapes and patterns they see as the food colouring flows through water and around the airplane.

For younger classes, a possible musical activity could involve making up sounds to go with various stages of the process. After watching the experiment once or twice, guide students in thinking up different sounds to associate with the experiment. Does the food colouring go “plop” or “splash”? Is it a high, squeaky sound? Maybe the sounds go fast then slow, or high then low. Have students use their voices and add movement to mimic the food colouring as it wends its way down to the bottom (end with everyone lying on the floor like the food colouring at the bottom of the container).
