Energy is everywhere around us, even though we can’t see it. Scientists say that energy is the ability to do work or cause change. We can see energy in action when things move, machines work, or when temperatures rise. Energy is what lights up our homes and cities and makes vehicles go. All living things need energy to grow, reproduce, and carry out their life activities.
Plants use energy from the sun, called light energy, to make food in the form of sugar. When animals eat plants or other animals, they get this energy too. This is how energy moves through the food chain.
There are two main types of energy: kinetic energy and potential energy.
Kinetic energy is the energy of movement. Some examples of kinetic energy include:
Potential energy is stored energy that an object has because of its position or condition. This energy can change into kinetic energy. Here are some examples:
Isn’t it amazing how energy works in so many different ways? To learn more about energy and how it changes forms, be sure to explore more educational videos and resources!
Explore your surroundings and identify different types of energy in action. Look for examples of kinetic and potential energy, such as a moving car (kinetic) or a stretched rubber band (potential). Write down your findings and share them with the class.
Create a solar oven using a pizza box, aluminum foil, and plastic wrap. Use it to melt chocolate or cheese, demonstrating how light energy from the sun can be converted into heat energy. Record the temperature changes and discuss your observations.
Conduct an experiment to observe energy transformations. Use a toy car on a ramp to demonstrate gravitational potential energy converting to kinetic energy. Measure the distance the car travels and discuss how energy changes form.
Play a game where you act out different roles in the food chain, such as the sun, plants, herbivores, and carnivores. Pass a ball representing energy from one role to another, illustrating how energy moves through the food chain.
Design a poster that illustrates the different types of energy and their examples. Use drawings or magazine cutouts to show mechanical, sound, light, heat, and electrical energy. Present your poster to the class and explain each type of energy.

Energy is all around us. Scientists define energy as the ability to do work or cause change. While we cannot see energy, we can observe the effects it has. Energy makes things move, powers the machines we use, and can increase temperature or produce sound. It is essential for lighting our homes and cities and for powering vehicles. All organisms require energy to grow, reproduce, and perform life processes.
Plants utilize light energy from the sun to create food in the form of sugar. This energy is then transferred to animals when they consume plants and other animals.
There are two main forms of energy: kinetic energy and potential energy. Kinetic energy is the energy of movement, and examples include mechanical energy, sound, light, heat, and electrical energy. You can learn more about these forms of kinetic energy in our related videos.
Potential energy is the energy an object possesses due to its position, composition, or state. This stored energy can be converted into various types of kinetic energy. Fuels such as petroleum, gas, and wood contain a form of potential energy known as chemical energy. When these fuels are burned, the chemical energy is transformed into light and heat.
Potential energy related to an object’s position above the ground is referred to as gravitational potential energy. For instance, a rock on top of a hill has gravitational potential energy, which is converted into kinetic energy as it rolls down due to Earth’s gravity.
An arrow in a bow possesses potential energy because of its position behind the drawn string, known as elastic potential energy. This elastic potential energy increases as the string is pulled back further. When the string is released, the potential energy converts into kinetic energy as the arrow flies forward.
That’s pretty cool! Be sure to check out our related videos to learn more about different forms of energy and conversions. Thanks for watching!

This version removes any informal language and maintains a clear and informative tone.
Energy – The ability to do work or cause change – The energy from the sun helps plants grow.
Plants – Living organisms that use sunlight to make their own food through photosynthesis – Plants need sunlight, water, and air to survive and grow.
Animals – Living organisms that need food, water, and air to survive – Animals depend on plants and other animals for food and energy.
Kinetic – Related to the energy of motion – A rolling ball has kinetic energy because it is moving.
Potential – Related to stored energy that has the potential to do work – A book on a shelf has potential energy due to its position above the ground.
Light – A form of energy that travels in waves and can be seen by the human eye – Light from the sun travels to Earth and helps us see during the day.
Heat – A form of energy that is transferred between objects with different temperatures – When you rub your hands together, you create heat energy.
Sound – A form of energy that travels through air, water, or solids as vibrations – When you clap your hands, you create sound waves that travel to your ears.
Chemical – Related to energy stored in the bonds of chemical compounds – Batteries store chemical energy that can be converted into electrical energy.
Gravitational – Related to the force of attraction between objects due to their mass – The gravitational pull of the Earth keeps the moon in orbit around it.
