• Magnetism is the force exerted by magnets when they attract or repel each other. Magnetism is caused by the motion of electric charges. Every substance is made up of tiny units called atoms.
• Light interaction refers to the processes through which light interacts with human skin or other materials, influencing their appearance attributes such as color and glossiness. It involves the study of fundamental optics concepts, and the quantification of physical terms related to light and matter interactions.
• Loud sounds in the environment can permanently damage or destroy the tiny and fragile hair cells within the cochlea- the small, snail-shaped organ for hearing in your inner ear- and diminish your ability to hear a range of sounds.

Asking Questions and Defining Problems
Asking Questions and Defining Problems
Asking questions and defining problems in grades 3-5 builds on grades K-2 experiences and progresses to specifying qualitative relationships.

PS2.B: Types of Interactions
PS2.B: Types of Interactions
• Electric, and magnetic forces between a pair of objects do not require that the objects be in contact. The sizes of the forces in each situation depend on the properties of the objects and their distances apart and, for forces between two magnets, on their orientation relative to each other. (3-PS2-3),(3-PS2-4)

1. Measurement of magnetic forces, patterns, and graphing data.
2. They compare lengths and learn how the sun’s light affects shadow size and shape.
3. Students observe how different objects (water, glass, paper, etc.) respond to loud sounds (e.g., by placing rice grains on a drum or speaker). They record which objects move or vibrate, then tally and graph the results.
1. Students test which household items (like spoons, nails, plastic pens) are attracted to magnets. They learn about magnetic materials and how magnets are used in tools and appliances (like fridge doors or electric fans).
2. Teach how to use sunlight to dry clothes or food (like fish or fruits). Discuss how to stay safe under the sun (wearing hats, avoiding long sun exposure).
3. Teach the effects of loud sounds on hearing. Discuss the importance of wearing ear protection when using noisy tools (e.g., electric saws or blenders). Introduce simple soundproofing methods (like padding or closing doors.)
1. Students learn how science helps us in real life, like in making clean energy (e.g., windmills use magnets inside to make electricity).
2. The Philippine government encourages using solar energy—a clean and free source of power. Learning how sunlight interacts with objects helps kids understand how solar panels, drying techniques, and natural lighting can help families and the environment.
3. The government promotes noise pollution awareness and occupational safety. Teaching students about how sound affects objects and people supports health campaigns and disaster alerts (like sirens or alarms).
7E's Lesson Plan
7E's Lesson Plan
l. Objectives
At the end of this lesson students will be able to:
A. Describe how magnets, sound, and light affect objects or human senses without direct contact,
B. Demonstrate the effects of magnets, sound, and light through hands-on activities or experiments, and,
C. Observe and express concern about how sunlight and sound affect the eyes, skin, and ears, showing value for health and safety.
In this part, I will ask the students:
Have you ever used a magnet to pick up something?
How does it feel when you stay too long under the sun?
Can sound affect you even if you don’t touch the source?
I will present a short video about the topic:

What do you observe?
Why do you think these things happen even without touching?
In this part, I will divide the students into 3 groups and they will observe the three stations they will visit. And then have them write down observations on their activity sheets/notebook.
Magnet Station
Task: Students test which objects are attracted to the magnet. (coin, nail, spoon, stone, paperclip, foil)
Goal: Sort them into "Magnetic" or "Non-Magnetic" categories.
Question: Why are magnetic objects attracted to magnets?And why are non-magnetic objects not attracted?
Light Station
Task: Shine flashlight toward their eyes from a distance.
Question: What do you see or feel when the light shines on your eyes?
Sound Station
Task: Ring a bell behind them.
Question: What do they feel or hear?
In this part, I will discuss..
Have you ever seen a magnet pull something without touching it? What materials do you think are attracted to magnets?
Magnetic Force
Magnets can attract or repel certain objects without touching them. This is called a force at a distance or non-contact force. Only certain materials like iron or steel are affected by magnets.
How can sunlight affect you even when you're indoors? Why do we wear sunglasses or apply sunblock?
Light from the Sun
Light travels in straight lines and can reach our eyes or skin even if we are not touching the sun.
Too much sunlight can harm our eyes and skin because of its strong energy (UV rays).
Have you ever felt your ears hurt from loud music? How do you know where a sound is coming from?
Sound Waves
Sound travels as waves through the air and can be heard even if the source is not touching us. Very loud sounds can damage our ears, showing that sound can have a physical effect even from a distance.
Can you name other forces that act without touching objects? How are they similar or different?
Non-contact Forces
These examples show that forces don’t need direct contact to cause effects.
Magnets, light, and sound are all forms of non-contact forces that affect us and objects around us.
In this part, I will ask my students some questions..
What would happen if there were no magnets?
In what ways does sunlight have a negative effect on our skin? How can this be prevented?
What will be the effect of loud sounds on our ears and which part of them will be most affected?
Group Sharing:
The assigned group leader will be the one to discuss in front of the class what they observed from the activity that they did earlier.
Homework:
Homework:
Observe and list at least 10 objects at home attracted by magnets and research on the function of magnets in each object. Write it down in your notebook.
TPACK-P Integration
TPACK-P Integration
The teacher uses technology such as YouTube videos and simulations to visually demonstrate how magnets, light, and sound affect other objects from a distance. This provides a multi-sensory experience that enhances understanding.
The lesson follows the 7E model, incorporating inquiry-based learning, hands-on stations, and group discussions to foster curiosity and engagement. Students are actively involved in exploring concepts through observation, experimentation, and collaboration.
The teacher ensures that students gain a clear conceptual understanding of how non-contact forces (magnetism, light, sound) work. Real-life scenarios are used to bridge scientific concepts with everyday experiences.
GRP Integration
GRP Integration
The lesson promotes a learning environment that values inclusivity, equality, and respect. This is achieved by ensuring that all learners, regardless of gender or background, are given equal opportunities to participate actively in group activities and collaborative tasks. Students are encouraged to express their ideas and observations freely while practicing respect for differing opinions and perspectives, fostering a culture of peace and mutual understanding.
The discussion on sensitivity to sound and light is connected to the learners' health rights, emphasizing the importance of self-care and protection such as wearing appropriate clothing or sunscreen for sun exposure and using ear protection in noisy environments thereby empowering students to take responsibility for their own well-being while recognizing the rights of others to a safe and supportive learning space.
