Welcome to the World of Light!
– Greet our bright minds
– Today’s topic: light and shadows
– Question: Where does light come from?
– Think about the sun, lamps, or candles
– Understanding light sources
– Light sources help us see and make shadows
|
Begin the class with a warm welcome, fostering an enthusiastic learning environment. Introduce the topic of light and shadows, which is a part of our everyday experience. Engage the students by asking them about the sources of light they know, like the sun or lights in their homes. This will help them connect the concept of light to familiar objects. Explain that light sources are things that produce light, and without light, we wouldn’t be able to see anything. Light also creates shadows when it is blocked by an object. Encourage the students to observe different light sources and the shadows they create throughout the day.
Exploring Light and Shadows
– What is light?
– Light lets us see everything around us.
– Sources of light
– Sun, lamps, flashlights are light sources.
– Naming light sources
– Light helps us see
– Without light, it would be all dark!
|
Begin the lesson by asking students what they need to be able to see. Guide them to the understanding that light is essential for vision. Introduce the concept of light sources, providing examples such as the Sun, lamps, and flashlights. Engage the class by asking them to name additional sources of light they have encountered. Emphasize that without light, we wouldn’t be able to see colors, shapes, or anything else around us. This will set the stage for understanding how shadows are formed when light is blocked.
Exploring Shadows
– What is a shadow?
– A shadow is a dark area where light is blocked.
– Where can we see shadows?
– Shadows appear on surfaces like floors or walls.
– Making shadows with hands
– We can create fun shapes using our hands and light.

This slide introduces the concept of shadows to first graders. Begin by explaining that a shadow is formed when an object blocks light, creating a dark shape on a surface. Show examples of shadows on the ground or walls to help them visualize. Engage the students by having them use their hands to create shadow shapes, such as a bird or a dog, using a flashlight or sunlight. This activity will help them understand how shadows are formed and how their shape can change. Encourage the students to experiment with moving their hands closer and farther from the light source to see how it affects the size of the shadow.
Exploring Shadows
– Making and moving shadows
– We can create shadows using our bodies or objects.
– Shadows change with light position
– When we move the light, the shadow’s shape and place change.
– Create your own shadows
– Use a flashlight to make shadows on the wall.
– Observe how shadows move
– See what happens to your shadow when you walk or wave!

This slide introduces the concept of shadows to first graders. Begin by explaining that shadows are created when an object blocks light. Use a flashlight and a variety of objects to demonstrate how to make shadows. Show how moving the light source or the object can alter the shadow’s size and position. Encourage students to make their own shadows using their hands or small toys, and observe how these shadows change as they move. This hands-on activity will help them understand that the position of the light source directly affects the appearance of a shadow. It’s a fun way for students to engage with the concept of light and shadows.
Shadow Experiments: Exploring Light
– Create shadows with objects
– Observe changes in shadow
– Shadows change shape and size with light movement
– Moving object closer to light
– Does the shadow grow or shrink?
– Discuss shadow behavior
|
This slide introduces students to the concept of shadows and how they are created by light. The class activity involves using a flashlight and various objects to create shadows and observe how they change. Students should notice the differences in shadow size and shape as the flashlight is moved. They should also observe what happens when the object is moved closer to or further from the light source. This will help them understand the relationship between light, objects, and the shadows they cast. Encourage students to ask questions and make predictions before the experiment. After the activity, discuss why shadows behave the way they do and how light travels in straight lines.
Fun with Shadows
– Shadows are fun to play with
– Create animals with hand shadows
– Use hands to form a bird, dog, or other creatures
– Let’s make shadow puppets
– We’ll try this together and see what we can make!

This slide is designed to engage first-grade students in a hands-on activity that demonstrates how shadows are formed and how they can be manipulated for fun. Encourage the students to experiment with their hands and fingers to create different shadow shapes on the wall. Use a light source such as a flashlight or lamp to cast shadows. This activity will help them understand that shadows are created when an object blocks light. It’s a playful way to introduce the concept of light and shadows, and it will also help develop their creativity and motor skills. Prepare to assist them in creating shadow puppets and encourage them to share their creations with the class.
Class Activity: Shadow Play
– Let’s explore and create shadows!
– Observe how shadows change outdoors
– Shadows look different throughout the day
– Make your shadow move
– Can your shadow wave, jump, or nod?
– Notice your shadow’s shape and size
– Does it grow longer or shorter?
|
This activity is designed to help students understand the concept of shadows and how they are created by the obstruction of light. Take the class outside to a sunny area where each student can clearly see their shadow. Guide them to observe how their shadow changes with the position of the sun in the sky. Encourage them to move and see how their shadow mimics their actions. Ask them to make their shadow wave, jump, or nod, and to observe changes in the shape and size of their shadow at different times. This will help them grasp the idea that the sun’s position affects the length and direction of shadows. Have a variety of activities ready for different students, such as tracing a friend’s shadow, comparing the shadows of different objects, or using props to create imaginative shadow shapes.
Shadows and Light: Fun Facts
– Light creates shadows
– Shadows mimic shapes
– If an object is round, the shadow is round too!
– Light’s position matters
– When light moves, shadows move too.
– No light means no shadows
|
As we wrap up our lesson on light and shadows, remember that shadows are formed when light is blocked by an object. The shape of the shadow can give us clues about the shape of the object that is blocking the light. Also, by observing shadows, we can tell the position of the light source. It’s important to note that shadows can only exist with light. Encourage the students to observe shadows at different times of the day to see how they change with the position of the sun. This will help reinforce the concept that the angle and position of light affect the shape and direction of shadows.
Shadow Tag Game
– Play shadow tag outside
– Try to step on shadows
– Be gentle and have fun
– Observe how shadows move
– Notice how shadows change with your movements
|
This slide introduces a fun and interactive game to conclude the lesson on shadows. Shadow tag allows students to engage with the concept of shadows in a playful way. Encourage the children to play outside in a safe area where the sunlight casts visible shadows. The objective is for them to try and step on each other’s shadows, which helps them observe the nature of shadows first-hand. Remind them to be gentle with their classmates during the game. As they play, prompt them to notice how the shadows move and change with their own and others’ movements, reinforcing the idea that light is necessary to create shadows and that they mimic the shape of the object blocking the light. This activity not only solidifies their understanding of shadows but also helps them to work on their motor skills and social interactions.
