Week 1

Have you ever looked up at the sky and seen the sun make

everything look bright and colorful? That's because of light!

Light is something that helps us see and makes things look

pretty.

Light can make things glow, shine, and shimmer in different ways. It travels in waves, like sound or ripples in a pond, and can bounce off things or go through them. Scientists have been studying light for a long time and have learned a lot about it. Without light, we wouldn't be able to see anything around us, so it's really important!

Before we start to learn about this interesting topic, discuss these questions with your partners:

Now, let's solve some activities in order to learn the basic information about light:

1) Draw a lightbulb in your notebook big enough to complete the following information about light: You can find the answers on the KidsBritannica website:

2. Watch the LaBrakazam video and analyze (you don't have to write the questions, but you should answer using complete sentences)

Why do you think the balloons exploded?
Do black objects reflect light?
Can we see without any source of light?
What is a camera obscura? and how do we see?
Why can we see the laser beam?
What's internal reflection?

3. Visit the GenerationGenius website and use the information to draw 3 natural light sources and 3 artificial ones.

4. There are two types of objects: luminous and non-luminous. We see non-luminous objects because they reflect light into our eyes. The moon is a non-luminous object because it doesn't produce its own light, it just reflects the sun's light. Draw a diagram to show how someone on Earth sees the moon by reflected light.

Have you ever wondered why your reflection

stares back at you in a mirror, why a straw

looks “bent” in a glass of water, or how a

simple beam of light can explode into a

rainbow of colors? Light is not just

something that helps us see—it’s full of

surprising tricks that happen all around

us every day. In this lesson, we’ll uncover

four amazing light phenomena: reflection,

refraction, dispersion, and absorption. Get ready to see the world differently, because once you understand how light behaves, even the simplest things—like a puddle, a window, or a sunset—will feel a little more magical.

During this class, we will study some of the phenomena created by the interaction between light and different materials: reflection, refraction, dispersion and absorption.

First, the idea is to learn the main concepts through a presentation, then, you will solve a short quiz (just practice, not gradable) to check what you understood about this topic.
