Activities

[Contributor - Kripa S]

1. In your village, visit a place that has a fence of wire. Take few small marbles or pebbles along with you. Throw them all in one go into the fence. You will observe that few of the pebbles will pass through the fence to the other side, and few will get hit and bounce back. This is how the electrons also move.

Lesson Plan version 1.1 activities

1. Show a picture of the periodic table and show the position of the natural and man-made elements, and other element groups like the noble gases, hard metals. Explain the criterion used for the ordering of the elements in the table. Then ask students to identify some common elements in the periodic table.

2. Play a game on characteristics of materials (Explain the game in the regional language) on this website : http://www.sciencekids.co.nz/gamesactivities/materialproperties.html

3. Using a magnet, demonstrate how one can separate iron nails from a mixture of iron nails and sand.
