SLJ Nanogirl: Make an optical illusion

Today, I did a task in which I made an optical illusion that tricks my eyes and brain to think something else.

First, I looked at Nanogirl's video to learn what optical illusions are and looked at some examples of them.

Second, I searched up on the internet what type of optical illusion I can make.

Next, I made my optical illusion on google drawings which was a mixed cat and a duck. 

If you focus on the small triangle on the left of the head it looks like a cat but if you look at the two big triangles on the right it will look like the beak of a duck.

Then, I showed my optical illusion to my father and he thought it was only a duck but when he looked at the left side of the head he thought it was the cat. He was so surprised and asked what animal it was and I said it was both.

Lastly, I thought about how I could improve my optical illusion and I realised that the bottom part on the right side doesn't look like a duck's feet. Next time I would try to make it look better. 

I learnt that optical means to do with our eyes, and optical illusion is where our eyes see something that isn’t there.

An interesting fact is that traditional cartoons are made up of thousands of individual drawings that are shown so quickly that our brains think the drawings are moving.

Something that I didn't know was that light bounces differently through water than it does through the air which is called refraction.

I liked doing this Summer Learning Journey task because I got to be creative in science and arts.
