This World of Things LOOKING AROUND ENVIRONMENTAL STUDIES - This World of Things

Draw three natural and three artificial things.

Things around us are made of different types of materials. Write down the names of three materials we commonly see around us.

Which of these words or phrases describe the spoon ?

Smooth	Rough	Dull	Shiny
	Feels cold to touch

Is it made of metal, wood, or some other material? Can you guess?

What material is your spoon made of?

Match the pairs:

A. Transparent	1. A lamp shade made of paper
B. Translucent	2. A plate
C. Opaque	3. A glass used in spectacles

Have you seen trees around you that bear flowers and fruits at special times of the year? If you have ever eaten a ripe mango or seen mangoes in the market or watched a mango tree through the year, try to guess- at what time of the year did Khushi draw her picture? Could it be around January or around June?

Things that are made by people are called 'artificial' like clothes, shoes, tables, etc. List out five things in each group.
Natural:___________
Artificial:___________

In their childhood, were these things made of the same materials?

Suppose you find a shining spoon. You don't know if it is made of metal or whether it is made of some other material and then painted with shiny paint. How would you find out?

List five objects and pair them with a material that is not suitable for it! Explain why these materials will not work to make these objects. One example is done for you

Objects	Materials	Reasons
Umbrella	Paper	Paper will tear if it gets wet in the rain.

In the table below, Khushi has grouped objects according to the materials that they are made of. Her list of objects is in the first column of the table. The names of the materials are in the second column.
The third column of the table is for you to complete. Here write the names of some objects you have seen that are made from that material. Some objects around you may be made from materials not in this list, e.g., clay and rubber are missing in Khushi's list. Use one of these to add an additional row in the table.

Khushi's list	Name of the material	Objects made of this material which are in your classroom or
Table, chair, door	Wood	For example, Pencil
Door, hinges, nails	Metal
Window panes, light bulb	Glass
Electric switches	Plastic

Let us colour the world!
Collect two or three see through bags, bottles or thin cloth of different colours. Look at a sheet of white paper through them.
Q.1 Does the colour of the paper appear to change?
Q.2 Does white paper appear different when you look at it through thin blue plastic or glass? Or, thin yellow plastic or glass?
Q.3 Do the colours of different objects appear to change? How did a blue object look through thin yellow plastic?
Q.4 Have you earlier experienced looking through coloured transparent objects? Try to recall such experiences.

Collect a few small objects of different materials from your surroundings like bottles, papers, cloth and utensils, etc. Look at a light bulb or a candle flame through them. You can see through some objects very clearly, you can partially see through some others, while you cannot see through some objects at all. Order these objects from those you can see through very clearly, to those you cannot see through at all.
