Write down below about what works are being done in the figure?
- Cycle riding
- Supplementing the crop with organic or chemical fertilizers for proper growth of the crop.
- Playing Game
- Walking with Luggage
In which instances do you use muscular energy in your day to day life?
We walk, ran, climb, pull and push the things from one place to another.
Write any four works you do using muscular energy.
Waling, climbing, pulling, pushing.
Write about any work done by wind energy
- production of electricity from wind
- people use to make boat and ships to move on the oceans with the help of wind.
How can mechanical energy be converted in to heat energy ? Explain with an example.
When we mb our palms, the palms warm, because of friction. When we beat a metal strip continuously with a hammer, it becomes hot. Mechanical energy can be converted into heat energy.
Write any two works done in your home using heat energy?
- Cook food
- Boil Water
Write your known names of solar energy devices which are used by you?
Define wind energy.
Any object that is moving has energy in it. Moving air also has energy. It is called wind energy.
How is wind used to Produce Electricity
Windmills rotate due to the fast movement of wind. Turbines rotating due to this wind energy produces electricity.
How is water used to produce electricity?
Water stored in a dam has potential energy which gets converted into kinetic energy when water passes through the gates of a dam. Stored water flowing through the gates of a dam
List the names of dams you know or which you have visited?
- Kabini dam
- Alamatti dam
Write two situations of saving electricity?
- Embrace natural light
- Unplug any appliances that aren’t in use.
Write any four works done by using electric appliances?
- Washing machine – washing cloths
- Electric Stove – water food
- Electric geyser – water heating
- Electric bulb – light purpose
Write the uses of bioenergy?
- It is used for cooking.
- The energy available from biogas can be converted into electricity and may used for many works.
If you have appliances which make use of fuels at your home, name them?
- Cooking purpose
Name the forms of energy.
- Muscular energy.
- Mechanical energy.
- Heat energy.
- Solar energy.
- Wind energy.
- Waters stored energy.
- Electrical energy.
- Chemical energy.
Think how energy changes from one form to another form in –
- A solar cooker
- An electric heater.
- We get heat and light energy from the sun, From solar energy, we can prepare food using solar cooker.
- Electrical energy is generated at power stations and supplied to our homes.
State the law of conservation of energy.
Energy can neither be created, nor be destroyed. It changes from one from to another. The total eneigy remains constant. This is called law of conservation of energy.
Name three appliaces where electrical energy is used.
Appliances such as electric iron box, computer, washing machine etc., use electrical energy.
In the following activities write that the energy changes from which form to what from?
|Running of petrol car||Chemical energy (fuel)||Mechanical energy|

By using clues in the bracket, write the alternate energy used [solar water heater, goober gas, solar cooker, solar cells].
|Activity||Alternate energy used|
|1. Instead of hearth
2. Electric geyser
3. Cooking rice on the hearth
4. Electric bulb
5. Listening to radio using electric
Solar water heater
Use the clues in the bracket and write and write which alternative energy can be saved by following activities given below. [Fuel, chemical, electric, charcoal]
