Activities

[Author - Kripa S]

1. Make a list of articles around you that are made of metal

2. List some examples of metal objects that have been made due to the properties :

a) Malleability

b) Ductility

3. Name some metal objects that exhibit:

a) Malleability

b) Ductility

c) Lustre

d) Hardness

e) Sonorous properties

f) Good conductor of heat

g) God conductor of electricity

4. Take a walk around your locality and make a table of the various metals and non metals used in various objects.

Lesson Plan version 1.1 activities

1. Materials- pieces of iron (iron nails), copper, zinc, sulphur powder, aluminium, carbon, magnesium and iodine.

Procedure-Observe the appearance of your samples. Look at their color. Decide whether they appear shining or dull.

2. Take some common objects like steel spoon, coal, lead of pencil, coin, chalk etc. and drop each of them one by one from a certain height. Listen to sounds and record observations in table 2 of textbook. (OR Listen to your school bell. Find out what material is the bell made up of.)

3. Take a piece of coal and hit with hammer. What happens? Will your result vary if an iron bar is used instead of coal?

4. Play a game on characteristics of materials (Explain the game to the students in the regional language) on this website-

http://www.sciencekids.co.nz/gamesactivities/materialproperties.html

5. Aim: To know the reaction of oxygen with

metals and non-metals

Burning of magnesium in Air- Demonstration video (English)- https://www.youtube.com/watch?v=m2i9jLPXprQ&t=63s (only up to 1:30 min). Take magnesium ribbon and bring it close to a candle flame until the ribbon starts burning. Observe. In a test tube, put some magnesium oxide produced and dissolve it in water. Test with blue and red litmus papers.

Reaction of Sulphur with oxygen-video demonstration-

6. Reaction of sodium with water. Take a small piece of sodium metal and put it in water. Follow the steps in the given video- https://www.youtube.com/watch?v=dmcfsEEogxs (NOT to be performed by students)

7. Reaction of Zinc with dilute hydrochloric acid-Video demonstration

https://www.youtube.com/watch?v=71fQGSj3yTE

Repeat the same with other materials like iron, copper, sulphur, aluminum, carbon, magnesium and iodine.

If there is no reaction, heat the test tube gently. If you still see no reaction, add 5 drops of conc. Hydrochloric acid. Now bring a burning Match stick near the mouth of the test tube and observe what happens.

8. Reaction between Zinc and copper sulphate-
