DEMO SCIENCE 6 ELECTRICITY AND ENERGY TRANSFORMATION MACATANGAY, SHIELA - Copy.pptx

This document appears to be a presentation on electricity and energy transformation presented by Shiela D. Macatangay to Grade 6 students. It covers key topics like: - The definition of electricity and that it is a secondary energy source obtained from converting primary sources like coal, gas, and oil. - The concept of energy transformation as the process of converting one form of energy to another. - Examples of energy transformation include hydropower plants that convert potential energy of water into mechanical and then electrical energy, and wind turbines that convert kinetic energy of wind into electrical energy. - Safety precautions around electricity use such as avoiding overloading outlets, not handling appliances with wet hands, and letting professionals

GOOD AFTERNOON GRADE 6
‘‘HELPING CHESTER’’
Mechanics: I have here a situation where you will help Chester what to do with the given situation. Are my instruction clear?
Chester, wants to watch the latest single of his favorite k-pop group which is twice. What are you going to do to help Chester watch his favorite k-pop group?
Chester is holding an ice cream, what are you going to do to help Chester not to melt the ice cream?
Chester, is tired and he want to sleep but it is too hot, what he is going to do make him feel relax?
Electricity and Transformation
Electricity Electricity is the flow of electrical power or charge. It is a secondary energy source which means that we get it from the conversion of other sources of energy, like coal, natural gas, oil, nuclear power and other natural sources, which are called primary sources.
Energy Transformation is a process of converting one form of energy to another.
Energy energy cannot be created nor destroyed.
Most power plants are fueled by coal, oil or gas. These fuels are fed into burners and the heat boils water into steam but the problem with these power plant is the pollution that they release into the atmosphere. Hydropower plant
ILIJAN POWERPLANT
Hydropower plant Hydropower plants convert potential energy into mechanical energy through water turbines, which then generate electricity. Hydropower plants, dams are built to hold the water in artificial lakes. Water is then released gradually to fall down, like an artificial waterfall
Hydropower plant
Wind turbine a turbine that converts the mechanical energy of its rotation into electrical energy. The faster the turbine turns, the more electricity is produced.

How do the appliances work?
Converting Electricity to other Useful Forms electricity gets converted to other forms of energy that we need or wants. Many appliances have motors-converter into kinetic energy.
What are the appliances in your home that has cooling elements?
What are the appliances in your home that has heating elements?
Some of our appliances provide heating elements which high resistance segment of metal that convert electricity into thermal energy, while cooling elements they have cooling coils inside. They absorb heat from the air, then bring the heat out.

what are the devices that convert electricity into light?
what are the devices that convert electricity into sound?
Electricity makes our lives comfortable, but it can be destructive when not used carefully. Many people have lost lives and homes due to accidents like short circuits and overloading.
Safety Precautions in Using Electricity  Avoid octopus connection. Do not use adapters that allow to many appliances to be plugged in.  Do not placed appliances close to water sources. Do not touch electrical appliances with wet hands
 Do not try to repair appliances yourself. Let us trusted repair men and technicians to do them for you.  Make sure that appliances you use are rated at 220 volts. If you want to use appliances rated at 110 volts, use the transformers with them.
We use electricity in our daily life. At present, many places in our country experience brownout due to shortage of electric supply.
Efficient Use of Electricity  Turn off lights and appliances when they are not in use  When ironing the last pieces of clothes, turn the setting to low or even turn it off.
 When using the washing machine, put as many clothes as possible in one load. It saves a lot of clothes in just one load  Monitor your electricity consumption. Inform your parents if your bill suddenly goes up.
Remember: We should always put those things into practice in order to conserve energy.

What are some safety precautionary in using electricity? Avoid octopus connection. Do not use adapters that allow to many appliances to be plugged in. Do not placed appliances close to water sources. Do not touch electrical appliances with wet hands Do not try to repair appliances yourself. Let us trusted repair men and technicians to do them for you. Make sure that appliances you use are rated at 220 volts. If you want to use appliances rated at 110 volts, use the transformers with them
What are the things we should practice to help us use electricity efficiently? Turn off lights and appliances when they are not in use. When ironing the last pieces of clothes, turn the setting to low or even turn it off. When using the washing machine, put as many clothes as possible in one load. It saves a lot of clothes in just one load. Monitor your electricity consumption. Inform your parents if your bill suddenly goes up.
Direction: On a sheet of paper write efficient if the statement is about to conserve energy, and safety if the statement is about precautions in using electricity. 1.Avoid octopus connection. 2. When food is on the stove is already boiling, switch to low setting or turn it off.
3.When buying appliances check for the energy saving features. 4. Check all the wirings on your appliances. 5. Do not place appliances close to water sources.
