Lesson 1: Forms of Energy

Energy is everywhere and it can do a lot of things. Energy is invisible. But, how can we tell when energy is there? If you see children running on the street and a light from the lampshade, hear a sound from the radio, or feel the heat of the sun, you can be sure that energy is in action.

All living and non-living things need energy. It warms our planet enough to make life possible. It enables people to do household chores or work in school. It illuminates every home, operates appliances, and moves cars.

In Physics, energy is described as the ability to do work or make changes in certain conditions. Energy can be classified in two types: kinetic and potential energy. Potential energy is energy stored in an object at rest while Kinetic energy is an energy in motion.

In this lesson, you will learn the different forms of energy such as mechanical energy, heat energy, light energy, sound energy, and electrical energy.

Additional Activities

Sources of Energy

In the previous activity, you have learned that you can obtain energy from the food you eat. Food, however, is not the only source of energy. The table below shows the different forms of energy. Write at least 2 possible sources of each form of energy. An example is given as your guide for this task.

Forms of Energy	Possible Sources
1. Light	Candle
2. Sound
3. Heat
4. Electrical
5. Mechanical
6. Chemical

Lesson 2: Energy Transformation

The food that you eat provides you the energy to do work. You can run, walk, swim, or do your homework and chores because of the chemical energy you get from food. Even sleeping, breathing, and eating require some energy from your body. It is important to note that the chemical energy that you get from food is not lost or used up when you do those activities. It is simply changed into another form of energy. The cells in your body break down the chemical bonds in the food and release the energy from those bonds. You then use this energy to keep your body organs working, move your muscles, ride your bike, or toss a ball. You might have observed that you feel hot and start sweating after running, biking, or playing. This is because some of the energy is transformed into heat.

The Law of Conservation of Energy states that energy cannot be created or destroyed. It may be transformed from one form into another, but the total amount of energy never changes. Energy can be changed from one form to another such as chemical energy into mechanical energy, heat energy, and many more.

Energy transformation occurs everywhere always. It can be observed at sunrise. As the light of the sun reaches the Earth, plants absorb it to make their own food. Light energy from the sun is transformed into chemical energy stored in plants. In cooking, the chemical energy of the Liquefied Petroleum Gas (LPG) is transformed into light and heat to cook food. Other examples where energy conversion takes place are in a battery-operated car, waterfalls, roller coaster, cleaning the house, walking, running, watching television, eating or chewing food, calling through cellular phones, driving a car, and many more.

Based on the activity, what is energy transformation?

What is It

In the activity, you have observed how energy is transformed from one form to another. Transformation of energy occurs in the flashlight. The illustration below shows the outside and inside view of the flashlight.

Figure 4: The outside and inside view of the flashlight.

[illustration: outside view of a flashlight; inside view of a flashlight showing two batteries, a circuit, and a bulb, with the labels “Chemical energy” → “Electrical Energy” → “Light Energy + Heat”]

Illustrated by Ryan Oliver S. Arellano

When the flashlight is switched on, the chemical energy from the battery is transformed into electrical energy through the circuit, and then transformed into light energy and heat released to the surroundings.

[chart: circuit diagram; Figure 5. Flow of electric current in a circuit.] Labels printed in the diagram: “Battery”, “electric current”, “Electrical Device (Light Bulb)”. The inset shows electrons (e-) inside a box with a minus (-) terminal on the left and a plus (+) terminal on the right.

Modified from https://www.canva.com

In a simple circuit, the source of energy is the chemical energy from a battery. Chemical energy present in a battery generates electricity as shown in figure 5. The electrons are allowed to flow through the wire that creates an electric current. Electric current that carries electric energy flows from the negative terminal towards the positive terminal of the battery thus giving energy to the load (light bulb).

Fossil fuels (coal, natural gas, petroleum) are all derived from of the bodies of plants and/or animals. In a power plant, these carbon-based fuels are burned to generate steam or heat that turn the turbines. Turbines are large wheels that rotate when pushed by steam, water, wind, or pressure. The turbines then drive the generators to produce electrical energy. The electrical energy produced by the generators is distributed to homes which is used to power our electrical appliances. Hence, energy is not produced or made in power plants. Instead, it is simply an energy that transforms from chemical (plants and animals) to heat to mechanical (turbines and generators) to electrical to sound when we turn on our radio or TV, heat when we use the flat iron, or mechanical energy when we switch on the electric fan.

Aside from carbon-based fuels, there are other alternative sources of energy. These are classified as either renewable or non-renewable energy sources (Table 1). It is important to conserve energy because the fossil fuels that we use are limited and emit harmful pollutants.

Table 1. Sources of Energy

Renewable Energy	Nonrenewable Energy
Wind Energy	Fossil Fuel ( coal, petroleum, natural gas, oil)
Water
Geothermal Energy
Biomass Energy (Biomass Fuel)	Nuclear energy
Tidal Energy (Tides)
Solar Energy

Transformation of energy may also be observed by simply doing household chores. When hammering the nail, mechanical energy is turned into sound energy and heat energy as you continue hitting the nail. When ironing clothes, the electrical energy from the source or outlet is transformed into heat that makes the iron hot. In a boiling water, the chemical energy from the LPG tank is transformed into light energy and heat that makes the water boil. At home, we use different appliances like TV, electric fan, air condition, refrigerator, electric lamp, etc. All these devices transform one energy to another form and release heat to the surroundings. The end product of energy transformations is heat wasted. Heat is collected in the surroundings and results in the warming of the environment.

I learned that energy transformation is _____

_____.

What I Can Do

A. Conserving Energy

Electricity plays a significant role in everyday life. Some of the sources of electrical energy currently used are fossil fuels. Burning the fossil fuels to provide electricity causes air pollution or landscapes to be changed or destroyed. It is important to conserve electricity to lessen the bad effects it brings upon the environment. Put a check on the items below which show (/) the different ways to conserve energy and (x) to those that do not.

______1. Use a large heating pan at all times when cooking. ______2. Turn off unnecessary appliances when not in use. ______3. Avoid frequent opening of the refrigerator. ______4. Refrain from using air conditioner during cool or rainy season. ______5. List down all things needed before going to the grocery story.

B. Scenario

Car, buses, motorcycles. and other fuel-powered vehicles are our means of going to school or work, buying food and supplies, and many others that require us to go to distant places. But these vehicles are also the primary cause of air pollution around the world. They give off toxic materials that can harm our health and environment. They also release carbon dioxide gases which cause the warming of the earth’s atmosphere.

Imagine that you live in the near future when fossil fuels are no longer available. Can you suggest other sources of electrical energy? What would be the consequences of using those other (alternative) sources of energy? You can draw your vision of an alternative energy source of electrical energy.
