There are many things that are actually waves. In class, we learned about sound waves and how sound travel from one place to another and hit different objects or matter. We also study two important parts of wave, they are amplitude and wavelength. These are very important because they can change what we hear or see. For example, when amplitude is high, the sound become very loud. When wavelength change, the color or pitch also change. Waves are everywhere around us, even we cannot see it with our eyes.

This presentation is about ocean waves. Before I make this, I did not know much about ocean waves and how they work. We research what ocean waves are and how they can cause damage to beaches and buildings near the sea. It was very interesting to learn because I find many new things during the research. We also try to think about some new and creative solution to solve this problem. I learn a lot from doing this presentation and understand ocean waves more now.

This is my canva project poster about the Optical Illusion. Optical illusion is something that tricks your brain into seeing something that isn't really there, or different. The picture I choose is the rubins vase because I have seen this illusion a lot. I learn that it is easy to trick my brain, so sometimes when I see something, it may not be what is really happening

I think most interesting in the class is the color bottle expeimernt, because it is different from paint. If you are painting, and combine all color, you get brown, but in light, you get white. So I was very confused, but after Mr.Andre explained, I finally understood why it is different. The experiment was very fun.

I want to learn more about optical illusion, because I think it is cool. You can sometime see things they are not really there, and I want to understand more about how the brain is tricked. In the picture, when I first saw it, I saw the girl has very skinny legs. But she is actually holding a bag of popcorn, which looks like the grass.
