A bottle of any liquid substance almost invariably needs shaking before
A bottle of something used in the environment, is taken to the child's
The teacher shows the child how to grasp the container with his dominant
hand, putting the forefinger on top of the screw top lid. This is done
because, in shaking a bottle, a cork or top is apt to fly off and the contents
splash out. The child is then shown how to shake fairly vigorously to get
the contents well mixed. This can be practiced with a corked container
or container with any type of top which is used for household cleaners.
