Introduction
Comparing the volumes of different objects
Pre-Requisites:
About different solids- namely Cube, cuboid & Cylinder and their importance
Activity:
Go to a nearby swimming pool. Notice that as length progresses; the depth of the pool goes on increasing. Based on this, divide this pool into different 3D objects & find the volume of each of them.
Real Life Question:
Comparing the volumes of different objects
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Volume | Space occupied by a 3D object |
| Cubic Unit | Unit for measuring volume. Volume of a cube whose side is 1 unit |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Rectangular Box | Take a glass of water. Fill the box with water. Once the water has filled the “volume” of the container, it will start overflowing. |
Real life uses :
Volume measurement is a constant requirement in all the fields of science and daily life activities. Depending on the present population, future population is predicted and with this data, the main supply tank which distributes water to the entire city is constructed. Here, volume calculations are very important.
Places to visit :
Go to a nearby swimming pool. Notice that as length progresses; the depth of the pool goes on increasing. Based on this, divide this pool into different 3D objects & find the volume of each of them.
Practical examples around us
| Examples | Explainations |
|---|---|
| Ice Cream | Check the back of the ice cream pack. Against the quantity, you will find “500ml” or “1 litre”. This is nothing but the volume |
| Water tank | During summer, when there’s lack of water in your house, you call for a water tanker. You order for the amount of water you need. That is also in liters. |
What you learn in Theory:
Volume of the Cuboid = Area of base x height = l x b x h
What you learn in Practice:
Cuboid volume measurement represents how much quantity of anything it can accommodate within itself. This has a lot of applications in the real world
