Clown Outline
Materials:- Large Sheets of Paper
- Marker (to outline children)
- Crayons, paint, markers, etc.
- Outline each child as they lay on paper. Then let them decorate the outline as if they were clowns.
Balloons and Weight
Talk about how different gasses weigh differently, then bring in two balloons
one blown up by you and one by a helium machine and let the children see the
diffidence. This is even more impressive if you can get a helium machine and
blow it up before their eyes!
The Big Top
Everybody circle round and lift the canvas off the groundPush and pull and watch it rise, the big top grows right before our eyes
Everybody circle round and lift the canvas off the ground
Sit and watch the circus acts singing
Everybody circle round form a great big ring upon the ground
Now we're set to watch the show
Circus acts both high and low
Everybody circle round and form a ring upon the ground.
Pin the Nose on the Clown
Give each child a nose (pompom with double sided tape on it) and blind fold
them and have them put the nose on the clown (you can spin the children but
it is better not to do this for younger ones)
