Hey there! I want to share a super cool trick that can fool your senses. The first time I saw it, I couldn’t believe my eyes!
Here’s what you need to do: Place your face about a foot away from your screen and focus on the dot you see there. Try not to blink and just keep your eyes fixed on that dot. It might feel a bit strange, but hang in there for a little while longer.
Keep staring, and then—bam! Do you notice anything different? When you look away, you might see normal colors, even though the image is actually black and white. This is called an afterimage.
Afterimages occur because of the color-receptive cells at the back of your eyes. When you stare at certain colors for a while, these cells get tired and stop responding as strongly. So, when you switch to looking at a black and white image, your eyes create colors that aren’t really there. It’s like your eyes are playing a little trick on you!
This illusion is just one example of how your senses adapt to the world around you. It shows that sometimes, you can’t always trust what you see. Your brain and eyes work together in amazing ways, but they can also be fooled!
If you enjoyed this trick, there’s so much more to discover about how our senses work. Keep exploring and learning about the fascinating ways our bodies interact with the world!
Gather some colored paper or markers and draw a simple image with bright colors. Stare at your drawing for about 30 seconds, then quickly look at a blank white wall or sheet of paper. Describe the afterimage you see. Share your results with your classmates and discuss why different colors might create different afterimages.
Work in groups to create a series of afterimage artworks. Each group should choose a different color scheme and design. Display your artworks around the classroom and take turns viewing each other’s creations. Discuss how the afterimages differ and what might cause these variations.
Imagine you are the color-receptive cells in the eye. Act out what happens when you stare at a color for a long time and then switch to a black and white image. Use props or costumes to make it fun. Explain to the class how your ‘cells’ get tired and what happens when they do.
Keep a journal of your afterimage experiments. Record the colors you use, the duration of staring, and the afterimages you observe. Try different lighting conditions and note any changes. At the end of the week, review your findings and write a short report on what you learned about afterimages.
Research other types of optical illusions and present one to the class. Explain how it works and what it reveals about our senses. Compare it to afterimages and discuss any similarities or differences in how our eyes and brain are tricked.
Here’s a sanitized version of the transcript:

Okay, so I have to show you this really interesting way to trick your senses. I couldn’t believe this the first time I saw it.
First, put your face about a foot away from the screen and stare at that dot right there. Try not to blink; just keep staring right at that dot. I know this feels a bit unusual, but just a little bit longer.
Okay, keep staring right there, and bam! Do you see normal colors now? Look away. Yeah, the image is still black and white. This is called an afterimage. It’s actually caused by the color-receptive cells at the back of your eye. When certain color-sensing cells are constantly stimulated, your body tunes them down so that they stop firing. Then, when you look at a black and white image, you see colors that aren’t really there.
This is a fascinating illusion and just one of the many ways that your senses adapt to the world around you. It might also be a reason why you shouldn’t trust them all the time.
Oh yeah, and follow my page to learn more!

Let me know if you need any further modifications!
Afterimage – An afterimage is a visual illusion that occurs when you continue to see an image after looking away from it. – After staring at the bright light, I saw an afterimage of the light even when I closed my eyes.
Colors – Colors are different wavelengths of light that are perceived by our eyes and interpreted by our brain. – In science class, we learned how colors can mix to create new shades.
Cells – Cells are the basic building blocks of all living organisms, including plants and animals. – We used a microscope to observe the different types of cells in a leaf.
Eyes – Eyes are the organs that allow us to see by detecting light and sending signals to the brain. – Our eyes help us see the world in vibrant colors and shapes.
Brain – The brain is the organ in our head that controls our thoughts, memory, and senses. – The brain processes information from our senses to help us understand our surroundings.
Senses – Senses are the ways we perceive the world around us, such as sight, hearing, taste, touch, and smell. – Our senses help us learn about the environment and keep us safe.
Illusion – An illusion is something that deceives the senses, making us see or experience something that isn’t really there. – The optical illusion made the straight lines appear wavy.
Science – Science is the study of the natural world through observation and experiments. – In science class, we conducted an experiment to see how plants grow in different conditions.
Trick – A trick is something that deceives or misleads, often used in the context of illusions or magic. – The magician used a clever trick to make the coin disappear.
Learn – To learn is to gain knowledge or skills through study, experience, or teaching. – We learn about the solar system by studying the planets and stars.
