What did you learn about air in this session (that took a couple periods)? Hopefully, you learned at least three BIG IDEAS!
What evidence do you have to explain the phenomenon that air takes up space (we didn't prove this in our video, but learned it in the first days of the lesson)?
What evidence do you have to explain the phenomenon that air has weight?
When Mr. Solarz watches your video, will he be able to find problems with your "proof" that air has weight? Remember when we watched videos together as a class he mentioned a few ways teachers could trick their students - make sure you didn't use any trickery!
1- I learned that gasses have weight.so I learned that air takes up space. I know that because when you have an empty glass and there is paper taped or stuck to the bottom, if you dunk it mouth down in a tub full of water the paper will stay dry. It does that because the glass or cup is as full as it can be, with air. Therefor air has volume. The last thing I learned is that air pushes pressure out in all places and directions. 2- As I said in the paragraph before you can do a simple experiment. I am going to share a different reason I know air takes up space with you now. When you blow up a balloon it expands, and if you blow enough air into it it will pop. That is because air is filling up all of the space there is in the balloon therefore air takes up space.
3- I know that air has weight because when you have a full balloon, and an empty balloon ties on a ruler perfectly balanced by a string the balloon side with the full balloon will tip over. The full balloon weighs more than the empty balloon because it has air in it.
4- Yes he will because we did an experiment that showed two balloons one full and one not, balancing on a yardstick, and the one with air in it tipped over because it had air in it.

not everyone has gone to school, and 14 are illiterate (not including children who are to young to read)
63 could have jobs, only 52 are working
if money was divided equally everyone would have $10,300
10 richest people have nearly 85% of the money in the world each has $87,500
the poorest 10 people have less than $2 a day- $600 per year
the other 80 people have something in between
half the people in the village average about $6 a day - $1,800 per year

1900's the life expectancy was 47
41 people live in places with malaria in it
6 contract malaria each year
80 people in the village received vaccinations against lots of deadly disease
in 1000 B.C.E only 1 person lived in the village
2150 there will be 250 people in the village
experts think that 250 is the maximum number that the village can hold
The statistics of the world really surprised me, some in a good ways, and some in bad ways. One of the things that surprised me in a good way was that people are progressively living longer. That surprised me in a good way because it means that people are living fuller lives, and that increases the chance of me and my family possibly living longer too. Something that surprised me in a bad way was that almost half of our population is not living in a sanitary place. That surprised me in a bad way because that makes me think and worry about the people who live in those conditions, and that they might me poor so if they get sick they might not be able to afford medicine. Therefore almost half of our population has an increased risk of dying. Following that idea, some things that upset me were that all of the money in the world is not divided nearly as equally as it should be. I believe that is wrong because everyone should have the same rights as everyone, and everyone should be equal. When you are in a mansion, and other people are living in the streets that is not equal. What motivated me to want to work for this cause is because some people are literally starving, eating their own muscle just to stay alive I just wish people could have a steady life like mos other people. Also I think yes, we have ignored it for a few years but that was only because we had way bigger issues to deal with. Now that we have settled down a bit we should be focusing in on other people's lives not just our own. I would change that by going all around the world with the help of a charity,and give people enough money to have a stable life going.
Particles in solids don't move, and don't fill the space they are in/ they have a definite volume.
Solids are always visible, but might be to small or too transparent to see with the naked eye.
They have a definite shape.
Particles in liquids flow and fill the space their in following the rules of gravity/ they have am indefinite shape.
Liquids are always visible, but might be to small, too transparent, or soaked into a solid to see with the naked eye.
You can always feel liquids when you are purposely doing so, when you are in good health, and if there is enough of the liquid around.
They have a definite volume.
Particles in gases flow and fill they spaces they are in, ignoring the rules of gravity/ indefinite shape.
We rarely see gases except for when the particles are big enough like steam, and our breath in the winter.
They have an Indefinite volume.

1.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?
What do you think liquids and gases are made up of?
1. Some properties that identify solids as solids are: all solids are hard, all solids have a definite shape, and they are always visible. 2. Gases are always filling in the space that they are in, all gases are transparent, and they have no definite shape. 3. Yes, they can be broken into pieces so small that you can only see them through a microscope. I know that because sand is broken up rocks, and at first you can see rocks then when it turns into sand you can only see its individual pieces under a microscope. 4. I think solid matter is made particles too small to see,even with a micro scope. I think that because everything can be broken down smaller than it is. All matter is made of 5. In think liquids and gases are made of loosely packed particles, and have an indefinite shape. Unlike solids that have a definite size and that have very tightly packed particles. 6. I think gases and liquids are made out of loosely formed particles. I think that because both of them are very flowy and take up all the space that it is in.
