Today was a bright and exciting day for Grade 4 at Templer Park International School Rawang (TPIS)! As part of our awesome STEAM (Science, Technology, Engineering, Arts, and Mathematics) program, we rolled up our sleeves for a hands-on science experiment to discover how light travels — and what we found out was brilliant!

Using just a few simple materials (and a lot of teamwork), we became real scientists. We created “light tunnels” using three index cards with tiny holes punched in the center. With a flashlight at one end and the classroom lights turned off, the challenge was to line up all the holes perfectly so the light could pass through.

It wasn’t easy at first! We had to work together, adjust the cards carefully, and use our observation skills. But once everything was aligned just right — WOW! The flashlight beam zoomed straight through all three cards. We actually saw light traveling in a straight line!

💡 What We Discovered:

• Light doesn’t curve or wiggle around — it travels in a straight line.
• If something blocks the path, the light stops.
• That’s how shadows are made and why we can’t see around corners!

🧠 Learning with Our Hands:

At TPIS, we believe learning is more powerful when we do it ourselves. This experiment was part of our STEAM education, where we explore science with hands-on activities, creative thinking, and real-world connections. It’s not just learning — it’s discovering, testing, building, and having fun!

🎉 Final Thoughts:

We had so much fun being light detectives today! From punching holes in cards to watching the flashlight beam shine through, every step taught us something new. Now, when we see light beams or shadows, we know exactly what’s going on — because we tested it ourselves!

Go TPIS Grade 4 — future scientists in action! 🔬🌟
