Reflection Questions:

What did you learn about air in this session? Hopefully, you learned at least three BIG IDEAS!
What evidence do you have to explain the phenomenon that air takes up space?
What evidence do you have to explain the phenomenon that air has weight?

I learned that it took many years for the Wright brothers to make the first airplane. I also learned how lift works, and where a lot of pollution comes from.
If you get a cup and put it face down in water and press, there will be a big pocket of air.
I made a video about, if you fill a balloon and put on 1 side of a stack and put a deflated one on the other side and hold it with a string the one with air will sink.

2 people in village at 500 BCE
100 people live in village now and growing
Around the year 2150 there will be 250 people in the village, experts think this will be the max capacity of people on Earth

I learned a lot about the world. It is getting more people every year or so, and a lot of people in the world don't get food, water or important things of survival. And about 1/4 of the world doesn't even have electricity! Some kids don't even get an education and have to work at home doing household chores or actually work somewhere. I was very surprised by all of this. By around 2150 Earth will be full which I guess you could kind expect it to happen some day because there are more people on Earth every year. I'm also very surprised that in 2012, the average age was only 68, my grandfather is 80 right now and it's only been 6 years. Also, only about 1/10 of the world has cars and I cross roads every day and I have to wait at least 30 seconds for cars to stop going.

Solids

Particles in solids in don't move and don't fill a space
Are visible but are sometimes to small to see
Are visible but are sometimes to transparent to see
Has a defiant shape/volume

Liquids

Particles in liquids flow and fill the space they're in, following rules of gravity
Are visible but are sometimes to small to see
Isn't visible when soaked into something
Assuming good health conditions you can always feel liquid when you try
They have an in-defiant shape but have a defiant volume

Gases

Particles in gases flow and fill the space they're in ignoring the rules of gravity
We can rarely see gases except for when the particles are big enough to see like steam and breath in the winter
Gases have no defiant shape nor volume

Properties of Dirt

Properties of Water

Properties of Air

Rough texture
Brown
Can dissolve
Opaque

Reflective
Transparent
Fills the space it's in

Doesn't smell
Transparent
Fills the space it's in

Reflection Questions

What unique properties can be used to identify a material as a solid?
What unique properties can be used to identify a material as a liquid?
What unique properties can be used to identify a material as a gas?
Do you think most solids we can see such as wood, rice, and flour could be divided into smaller and smaller pieces?
Based on this information, what do you think solid matter is made up of?
What do you think liquids and gases are made up of?

It has a defiant shape and don't fill the space they are in. Most solids are be changed by heat.
It has no defiant shape and fills it's container
It floats, fill the container it's in, has no defiant shape, and can be compressed
I think they could split more because that's not as small as they get
I think it's made up of molecules and particles
I think it's also made up of molecules and particles
