ƒeƒLƒXƒg ƒ{ƒbƒNƒX: SCIENCE CONCEPT ƒeƒLƒXƒg ƒ{ƒbƒNƒX: The dragonfly can be balanced on its head because the point of gravity was there. The location of the center of gravity of the body of the dragonfly is on its center. The wings of the dragonfly move the center of the gravity in the front of the body. Moreover, the wings of the dragonfly has also have the center of gravity on its center. Thus, the combination of the center of the gravity moves in the point of head when the wings are tilted downward.

Taking it further:

 

1. Students could cut out other shapes and attempt to make it balance.

2. Ask student to explain the balancing object using equilibrium.

1. Cut off the wings and the body.

2. Cut off between two wings.

3. Glue wings and body.

 

4. Fold the wings and head down a little.

5. Put the head of the dragonfly on your finger tip..
