Welcome to YTSchool! 🌟 In today's First Grade Science lesson, we are exploring the world of SIGNALS. 📢💡
Have you ever wondered how cars "talk" to each other without using words? Or why police cars have such loud sirens and bright flashing lights? In this video, we use fun stories and animations to learn how light and sound send important messages over long distances to keep us safe.
In this video, you will learn: ✅ How traffic lights use Red, Yellow, and Green to guide us. ✅ How car horns and blinkers help drivers communicate on the road. ✅ Why emergency vehicles use both loud sirens and flashing lights. ✅ The difference between a light signal and a sound signal.
Perfect for 1st-grade explorers, teachers, and homeschooling families. SUBSCRIBE to YTSchool to complete the full First Grade Science course with us! 🚀
