Скачать или смотреть Air

In this activity children will understand about air and air force. Also they will know about space vehicles.

First ask children to blow the air from mouth keeping hand in front of mouth and let them feel air.

Ask children from which other places we get air? We get air from fan, ac, cooler etc. Show them rocket cut out and ask what is this?

It is rocket which goes up up up in the sky in space. Ask them rocket travels on road? It travels up up up in the space.

In air rocket first do not close the thick straw from top, pass thin straw from thick straw and blow the air out.

Question them why is the air rocket not launching? Because air is passing out from the straw and no force is applied.

Now let us lock the thick straw from top using tape, pass thin straw from thick straw and blow the air out.

Question them why is the air rocket now launching? Because now air now not coming out and it is creating a force at the place we have locked the thick straw and due to which it launches.
