Hello Universe!

INTRODUCTION 

Energy is all around us it's in the light that helps us see, the heat that cooks our food, the sounds we hear, and even inside our own bodies. By understanding how energy works in our daily lives we learn how to use it wisely, stay safe, and appreciate the simple things we do everyday from turning on a light to eating a good meal. Energy is not just in science it's in us, in our homes, and in the world around us.

CONTENT

Sound, Light, and Heat energy and its sources

PROBLEM

How do we use sound, light, and heat energy everyday at home, in school, and community?

BIG IDEA

4. The total amount of energy in the universe is always the same but energy can be transformed when things changed or are made to happen.

CONTENT STANDARD

Energy is present whenever there is movement, sound, light, and heat.

LEARNING COMPETENCIES 

10. Identify that energy is something that can cause change including light, sound, and heat energy; and

11. Observe and identify sources and uses of light, sound, and heat energy at school, at home, and in the local community.

TOPICS TO BE COVERED 

1. Definition of energy and its sources

2. What is light energy?

3. What is heat energy?

4. What is sound energy

DISCUSSION OF CONCEPTS

1.  Energy is what makes things move or change. It comes from batteries, sun, electricity, and fuel.

2. Light energy helps us see. It comes from the sun, flashlights, bulbs, and it travels in a straight line.

3. Heat energy comes from the sun ,fire, stoves, and moving objects. Heat energy makes things warm.

4. Sound energy was made by vibrations. This kind of energy travels through air, water, or solids and helps us hear.

Next Generation Science Standards (NGSS) Alignment 

Performance Expectation/Standard  

Students who demonstrate understanding can:

K-PS3-1. Make observations to determine the effect of sunlight on Earth's surface.

Science and Engineering Practices

Planning in carrying out investigations to answer questions or test solutions to problems in k -2 builds on prior experiences and progresses the simple investigations, based on fair tests, which provide data to support explanations or design solutions.

Make observations (first hand or from media) to collect data that can be used to make comparisons. (K-PS3-1)

Disciplinary Core Idea

PS3.B: Conservation of Energy and Energy Transfer

Sunlight warms Earth's surface. (K-PS3-1), (K-PS3-2)

Crosscutting Concepts

Cause and Effect

Events have causes that generates observable patterns. (K-PS3-1), (K-PS3-2)

ELICIT

The teacher begins the class with warm greetings and the prayer to set a respectful and calm  atmosphere. After checking attendance, the teacher asks students questions about what they already know about light, heat, and sound energy. Their answers are recorded recorded in the "K" section of a KWL chart. Students are also encouraged to share questions or things they're curious about, which are then added to the "W" section. This helps activator prior knowledge and prepares them to engage with the new lesson.

ENGAGE

To capture student interest, the teacher plays a short educational video about the three types of energy and their sources. After watching, students are asked to identify which type of energy they saw, how they are used in daily life, and why they are important. This activity helps make the lesson more relatable and encourages a student to think critically about energy in their everyday experiences.

EXPLORE

Students are divided into small groups and given simple materials: a flashlight, a mirror, and a glass of water. True guided hands-on activities, they observe how light reflects off the mirror and refracts through water. These fun and interactive experiments allows students to discover scientific concepts through observation and teamwork, building curiosity and deeper understanding.

EXPLAIN

After the experiments, the teacher explains the concepts of reflection and refraction, using the group observation as examples. Light travels in a straight line, reflects off mirrors, and bends when passing through water. The teacher also briefly explains how heat and sound energy work, answering any questions students may have. This part clarifies and reinforces what the students discovered during the exploration phase.

ELABORATE 

To apply what they've learned, students work in group to build a miniature house model. Each house must include three rooms that represents the uses of light, heat, and sound energy. Students label objects in their models that show energy usage and use rulers to design them accurately. This creative task how to students connect the lesson to real-world settings and encourages collaboration and problem solving.

EVALUATE 

To assess learning, students complete a written questionnaire about light, heat, and sound energy. The class mayor and secretary help distribute the materials, and students are encouraged to answer honestly and quietly. This part allows the teacher to check for understanding and identify areas that may need more explanation.

EXTEND

For homework, students choose one type of energy (LIGHT, SOUND, HEAT) and observe it at home over 2 days. They record the source, use, and who benefits from it in a simple table. Additionally, they write a short reflection on how to use that energy wisely and the possible consequences of wasting it. They are encouraged to include drawings or photos to show their observations creatively. This task helps extend learning beyond the classroom and promotes awareness of energy conservation.

WHAT IS SOUND ENERGY?

Sound energy is a type of energy that is produced when an object vibrates, creating waves that travel through a medium like air, water, or solid materials. This vibrations reach our ears and are interpreted as sound. Sound energy cannot travel through a vacuum because it needs a medium to move.

Sources of sound energy include anything that vibrates to produce sound. Common sources are: 

• Musical Instruments (drums, guitars, and pianos)

• Human Voice (vocal cords vibrate when we speak or sing)

• Animals (barking dogs, chirping birds, etc.)

• Machines and Vehicles (engines, alarms, sirens)

• Natural Sources (thunder, waterfalls, wind blowing through trees)

WHAT IS LIGHT ENERGY?

Light energy is a form of energy that travels in waves and can be seen by the human eye. It comes from sources like the sun, light bulbs, and fire. Light energy allows us to see things and can travel through space, air, and some materials, but not through opaque objects. It also helps plants make their food through photosynthesis.

WHAT IS HEAT ENERGY?

Heat energy, also called thermal energy, is the energy that comes from the movement of tiny particles in matter. The faster these particles move, the hotter the object becomes. Heat energy can be felt and transferred from one object to another through conduction, convection, or radiation. Common sources include the sun, fire, electricity, and hot objects.
