Select those objects from the following which shine:
Glass bowl, plastic toy, steel spoon, cotton shirt
The objects which shine from the following are:
(i) Steel spoon
(ii) Glass bowl.
Match the objects given below with the materials from which they could be made.

(iv) A piece of wood floats on water. (True)
(v) Sugar does not dissolve in water. (False)
(vi) Oil mixes with water. (False)
(vii) Sand settles down in water. (True)

Given below are the names of some objects and materials:
Water, basket ball, orange, sugar, globe, apple and earthen pitcher
Group them as:
(a) Round shaped and other shapes
(b) Eatables and non eatables
List all items known to you that float on water. Check and see if they will float on an oil or kerosene.
Wooden block, Paper, Balloon, Hair, plastic bottle, wooden logs, Boat etc. will float on water. A few of these like hair, balloon can float on kerosene or oil.
Generally, substances have less density than oil and water can float.
For example, few types of wood have densities higher than oil but less than water, so it floats on water but not on kerosene.
Find the odd one out from the following:
