How Light Behaves - Lesson for Grade 1, Chapter - Sound and Light
In the lesson "How Light Behaves," first-grade students will embark on an illuminating journey through the fascinating world of light, as part of their Sound and Light unit in Science. Through engaging activities including the Light Reflections Worksheet, the Transparent, Translucent, or Opaque Worksheet, and the How Light Travels Worksheet, students will discover key concepts about light that are essential for their foundational scientific understanding.
Students will learn about the nature of light and how it reflects off surfaces, which is fundamental in understanding how we see objects around us. This knowledge is crucial for their comprehension of basic optical phenomena. The Transparent, Translucent, or Opaque Worksheet will introduce them to the different ways light interacts with materials, helping them understand why we can see through some objects but not others. This concept is vital in daily life, explaining everything from why we can see out of windows to how sunglasses protect our eyes.
Additionally, through the How Light Travels Worksheet, students will explore the straight-line propagation of light and its implications for how shadows are formed and how we perceive the world.

Activity 1 / Light Reflections Worksheet
Use this worksheet to teach your students that some objects have smooth flat surfaces that can reflect light very well. What this means is that all the light beams will bounce off of them. It is even possible to see our own reflections in these objects. Ask your students if they can give you some examples of objects where we can see our reflections. Then, look at the pictures with them and help them check off the objects that can reflect light and form a reflection.

Activity 2 / Transparent, Translucent, or Opaque Worksheet
Before starting this exercise, it might be useful to remind your students what transparent objects, translucent objects, and opaque objects are. Transparent objects are those things that we can see through, translucent objects are not completely clear or transparent, but allow some light pass through them, and opaque objects completely block light from passing through them. Your students will need to look at the pictures in this worksheet and check off if each object is transparent, translucent, or opaque.

Activity 3 / How Light Travels Worksheet
With this colorful worksheet, your students can learn more about the way light travels. They will learn that light beams travel in a straight line, and cannot go around corners. Students will need to look through the pictures and check off all the correct examples of how light travels.
