The signals by using hands is making me feeling fun and interested, because that's another ways to helps us interact and communicate with others, people with disabilities, and some situations that you need a secret language instead of talking. I only learned about 2 ~ 5 hands laguage before, so this time I learned how to shows the signal of every letters by showing dots and lines by use one finger, and a five sign, all by hands. Also learned how to write that secret and special signs for sentences or words.

This STEM PROJECT two is to find a optical illusion and describe about that picture (what type of illusion it is, how it works, what did I see, real life examples). I chose a Physiological Illusion, things we see will send messages to our brain, and your senses part of the brain will send back the messages that been changed and fix to you. That makes the illusion happens even though it’s just a simple nothing wrong picture or view. It will automatic re-read and understanding it by using the pass experience, back ground, and gives you a fixed image that was be over-understanding by yourself. Like the color, size, clear. So as this picture, there's four grey line, but it seems like two dark and two bright, but actually they are all the same. In this Unit, I learned a lot about color and light, lenses, reflection and refraction, convex and concave. (also part of Unit 2 lessons)

I might want to learn more about signals, which means different kind of signals, there's digital signals, hands signals, numbers signals, and maybe there's more signals that I don't hear before and see before. So that's the one I want to see and learn more about.
