Class 5 EVS Chapter 7 Notes Energy How Things Work
Class 5 Energy How Things Work Notes – Energy How Things Work Class 5 Notes
→ Energy: Power that helps things move, heat up, make sound or light up
→ Heat Energy: Warmth that comes from fire, the Sun or hot things
→ Sound Energy: Energy that makes sound, like vibrating strings or moving air
→ Movement Energy: Energy that causes motion (e.g., wind pushing a swing)
→ Fuel: Substances like petrol, diesel, coal or gas that provide energy
→ Electricity: A form of energy used to run appliances and machines
→ Renewable Energy: Energy from natural sources like sun, wind and water that never run out
→ Solar Energy: Energy from sunlight
→ Wind Energy: Energy from moving air
→ Water Energy: Energy from flowing or falling water
→ Clean Energy: Energy that doesn’t pollute the environment
→ Stored Energy: Energy saved in batteries or inside our body for later use
→ The Sun gives us light and heat. Things around us move, light up and make sounds or get warmer or cooler; all this happens due to energy. Energy is what makes everything work. Food gives energy to our bodies. Animals also get their energy from food. All animals need energy to move, fly, swim, run and protect themselves.
→ We use different fuels every day for many activities like cooking food, lighting diyas and running vehicles. These fuels provide the energy needed to make these things work. Electricity is a powerful source of energy that runs many things around us. We use it at home and it is also used widely in many industries to run machines. Electricity is used for producing things like clothes, toys, books, food, cars, etc.
→ The electricity is mostly generated by burning fuels like coal. The burning of coal creates a lot of smoke and harmful gases that pollute our environment and harm our health. There are also clean and natural sources of energy-like sunlight, wind and water. Using these sources for generating energy is safer for the environment and doesn’t pollute the air.
→ Sunlight can be used for drying, heating or even creating electricity. Solar panels capture sunlight and convert it into electricity. Wind can turn windmills to generate electricity. Fast-moving water or water falling from a height can spin wheels to work or make electricity.
→ By observing and understanding how energy flows from sources like the Sun or wind to actions like drying clothes or running machines, we become more aware of the power all around us. Energy is precious and it makes our lives active and alive.
