What is a light source?
Year/Grade 3
Science
30 students
This lesson aligns with the Science national curriculum standards for understanding the role of light in everyday life.
| Step Number | Step Title | Length | Details |
|---|---|---|---|
| 1 | Introduction to Light Sources | 5 mins | Begin with a brief discussion on what students think a light source is. Introduce the lesson objectives. |
| 2 | Printable Card Activity | 5 mins | Hand out printable cards to students that they will fill out during the lesson regarding different light sources. |
| 3 | Group Activity | 10 mins | Divide students into small groups. Assign each group to identify objects around the classroom that act as light sources. Each group collaborates to discuss findings. |
| 4 | Physical Activity Break | 5 mins | Lead a short physical activity to re-energize the students, such as "Simon Says" with light-related commands. |
| 5 | Demonstration | 5 mins | Use a flashlight to demonstrate how light fills a space and how it can change the perception of an object. |
| 6 | Group Discussion | 3 mins | Regroup and discuss as a class what each group discovered about light sources. |
| 7 | Collecting Cards | 2 mins | Collect or random check the printable cards filled out by students to ensure understanding of the concepts discussed. |
| 8 | Conclusion and Recap | 5 mins | Summarize key points about light and darkness. Reinforce the definition of a light source and its importance. Give brief instructions for homework. |
Students will complete a short worksheet at home to identify different light sources in their environment and write about their importance. Collect homework during the next lesson without student presentations.
"Good morning, class! Today, we are going to explore a fascinating topic in science. Can anyone tell me, what do you think a light source is? [Pause for responses] Great ideas! A light source is something that produces light, and it helps us to see things around us. By the end of today's lesson, you will be able to recognize different light sources, understand that darkness is just the absence of light, and work together in groups to share your discoveries. Let’s get started!"
"Now, I have some printable cards for each of you. Please take one and a pencil. On this card, you will list different light sources that you can think of as we go through the lesson. Write down examples as we discuss them. Remember, these cards will help guide us in our activities today!"
“Let’s form small groups! Please move into groups of four. I want each group to look around the classroom for objects that can be light sources. You have ten minutes to discuss and list as many as you can find. Remember to talk together and share your ideas. Ready? Go!”
"Fantastic job, everyone! Now that we’ve done some thinking, let’s get up and move a bit! We are going to play 'Simon Says.' I’ll say something like, 'Simon says shine your light like a flashlight!' and you need to do that action. If I don’t say 'Simon says' and you do it, you need to freeze. Let’s start!”
“Okay, everyone, let’s gather back together. I want to show you something interesting with this flashlight. [Turn off the classroom lights if possible]. When I turn on the flashlight, watch how the light fills this space. [Shine the flashlight around the room] Now, does anyone notice how the light changes how we see objects? [Pause for student observations] Excellent! This demonstrates how light can reveal things and create different effects.”
"Now, let’s come together again. I want each group to share what you found about light sources. Raise your hand to share, and I’ll call on you. What did your group discover? [Promote discussion and ensure each group contributes] Very insightful ideas, everyone!"
"Now it’s time to collect those printable cards! Please hand them in to me as I walk around. I will take a quick look at them to see how many light sources you listed. Make sure you wrote down what you understood from today's lesson."
"To wrap up our lesson, let’s quickly review what we learned today. Who can remind us what a light source is? [Wait for responses] Exactly! We learned that light helps us see, and darkness is simply when there is no light. It's important to recognize these everyday light sources around us. For homework, I want you to identify different light sources in your home. Write a short paragraph about each one and its importance. We will collect these in our next lesson. Well done today, everyone!”

Let's get moving, everyone,
It's time for exercises – let's have some fun!
Stretch your arms up high to the sky,
Touch your toes, and give a little sigh.
Jump in place, let’s hop with glee,
Turn around, spin like a bumblebee!
Shake your body, let your hands wave,
Now march in place, be bold and brave!
Squat down low, pretend you're a chair,
Stand up tall, show us your flair.
Do a silly dance, just let it flow,
Wiggle your fingers, let your joy show!
Take a deep breath, inhale so wide,
Exhale slowly, let calmness reside.
With a clap and a cheer, let's end it right,
Great job, everyone! You've shone so bright!
