Shadows are a fascinating aspect of light and its interaction with objects. In this lesson plan wonders of shadow, students will learn about how shadows are formed and why they are important.
Say: Light can pass through a few objects but can not pass through most of the objects.
We will begin by discussing how light interacts with different objects. Some objects, such as transparent materials, allow light to pass through, while most objects do not. This interaction creates a shadow.
Say: When any object blocks the way of light it casts a shadow.
Instruction: Distribute shadow frames to each group. The shadow frames are made of transparent material, and students will use them to observe how different objects cast shadows.
Instruction: Make room dark and keep shadow frame in way of torch or candle.
Say: You can see the boundary of the frame doesn’t allow light to pass, so it is casting a shadow. Say: The frame is made with transparent material. We know light can pass through transparent material, therefore it is not casting a shadow.
Say: Now I will put different objects in this frame and you will observe how they cast a shadow.
Instruction: Put different objects in the frame to cast the shadows. Explain to the students that light cannot pass through the object, which is why a shadow is formed.
Instruction: Divide the class into groups of five students each. Give every group one shadow frame. Instruction: They must sit in a semi-circle facing a wall.
Instruction: Place the torch in the middle of the semi-circle where the light will fall on the wall.
Say: Every group will use its shadow frame to cast a shadow on the wall. You have the freedom to choose any object from the class.
Instruction: Let students enjoy this activity.
Instruction: While students are busy with the activity, the teacher will go to each group and ask questions.
Ask: Why is this object casting a shadow?
Ask: Is the shadow of the same size as the object?
Ask: Do all the objects make shadows?
Ask: What is the most common shadow we see daily? Ans: Our own shadow
Ask: Can objects cast shadows during the night?
Through this lesson plan wonders of shadow, students will learn about the importance of shadows and how they are formed. They will also have the opportunity to observe and experiment with different objects and their shadows, making the learning experience both hands-on and interactive.”
