Have you ever wondered how shadows change size? A shadow is the dark shape that appears when something blocks light. To see a shadow, you need a source of light. For example, on a sunny day, your body can block the sunlight, creating a shadow on the ground.
Shadows can be big or small, and they can be seen whenever there is light, whether it’s daytime or nighttime.
Let’s have some fun with shadows using a flashlight and a toy lion. When we turn on the flashlight, the lion blocks the light, making a shadow.
What happens if we move the lion further away from the flashlight? The shadow becomes smaller! Now, what if we move the lion closer to the flashlight? The shadow becomes bigger!
What if we move the flashlight instead of the lion? If we bring the flashlight closer to the lion, the shadow grows bigger. If we move the flashlight further away, the shadow becomes smaller.
Isn’t it amazing how shadows change size? Try experimenting with different objects and light sources at home to see how their shadows change!
Thanks for exploring shadows with me! See you next time!
Shadow Size Experiment: Gather a few small toys and a flashlight. In a dim room, shine the flashlight on each toy and observe the shadows. Try moving the flashlight closer and further away from the toys. What do you notice about the size of the shadows? Draw a picture of your favorite toy and its shadow when the flashlight is close and when it’s far away. Discuss with a friend or family member why the shadow changes size.
Shadow Hunt: Go on a shadow hunt around your home or outside. Look for shadows created by different objects like trees, furniture, or even your own body. Can you find a shadow that is bigger than the object making it? How about a shadow that is smaller? Take a picture or draw what you find. Think about what might be causing the differences in shadow sizes.
Create a Shadow Puppet Show: Use your hands or cut out shapes from paper to create shadow puppets on a wall. Experiment with moving your hands or puppets closer and further from the light source. How does this change the size of your shadow puppets? Put on a short shadow puppet show for your family, explaining how you make the shadows change size.
Sure! Here’s a sanitized version of the YouTube transcript:

**Sources of Light and Shadows**
How can we change the size of a shadow? A shadow is the dark shade created when an object blocks the path of light. There must be a source of light in order to cast a shadow. For example, you might have noticed that your body casts a shadow on the pavement on a sunny day. That’s because the sun is a source of light, and your body prevents the sunlight from reaching the pavement.
Shadows come in different shapes and sizes and can be observed wherever there is a source of light, day or night.
Let’s explore what happens to an object’s shadow when it is moved closer to and further away from a source of light. Here we have a flashlight and a lion. When we turn the flashlight on, a shadow is produced as the lion blocks the path of light.
Now, let’s move the lion further away from the source of light. The shadow is now smaller. What do you think will happen when we move the lion closer to the source of light? Yes, the shadow gets bigger!
How do you think the shadow will change if we move the source of light instead of the object? Let’s have a look. If we move the source of light closer to the lion, the shadow grows bigger. If we move the flashlight further away from the lion, the shadow grows smaller.
That was fun! See you next time!
