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?
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. Some of the things that I learned about air are that air actually has weight. Another thing that I learned was that air also takes up space 2. Some evidence that I have that air actually takes up space is if you pump air into a yoga ball you can sit on it and the ball get bigger because there is air in it. 3. Some evidence that I have that proves air has weight is I did an experiment to see if a balloon weighed more with air or if it didn't have air and the one that had air in it weighed more. 4. No, because the trickery was to start it where the balloon that was not inflated started not inflated and he would tilt the stick to make it so the balloon that was not inflated looked like it weighed more but we started out with both of the balloons inflated.
Explain what surprised you about the statistics of our world.

United Nations trying to make sure that we have good future
If the world were a village you would have to pretend that the village represented the whole world and the village had 100 people. Some of the things that really surprised me were 60 people were from Asia which is a ton considering it was out of 100. Another crazy thing that I learned was there are more phones then there are people which I thought was crazy because I would not have thought that some people had multiple phones and almost everyone has a phone. Probably the craziest fact that I learned was there are 700 chickens in the world which is like 7 time as many people on Earth. Some things that upset me and that I wished were different were 30 people which is 30% of the people o Earth don't have a reliable source or food. Another sad thing that upset me was 13 people do not have a safe source of water. Something that made me want to improve the situation was when I learned that 30 people in the village didn't have a reliable source of food it made me want to help them. Something that I think I can do to help this is every once in a while if I see someone who needs food on the street I could ask one of my parents if we could help them.
Particles in solids don't move and don't fill a space they have a definite volume.
Solids can always be seen except those that are too small or transparent for the naked eye.
Particles in liquid flow and fill the space they're in, following the rules of gravity they have an indefinite shape.
Liquids can always be seen except those that are too small, transparent, or soaked into a solid.
Assuming good health conditions you can always feel liquid and there is enough of it.
They have a definite volume
Particles in gases flow and fill the space they're in, ignoring the rules of gravity they have an indefinite shape.
You can rarely see gases except for when the particles are big enough like steam or breath in the winter.Have an indefinite volume.
Lots of spots
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?
Answers 1. Some unique properties that can be used to identify Solids are the particles don't move that much so it is usually pretty hard or if you put it on a fork it will not fall through the cracks. It also does not fill it's space and it has a definite shape and volume. 2. Some unique properties that can be used to identify liquids are they are wet if you stick your hand in it and it has an indefinite shape but a definite volume. Liquids can sometimes soak into solids. 3. Some unique properties that can be used to identify gas is it has an indefinite volume and shape. You also can't see gases. Gases also always expand or get smaller depending on the size or there shape. 4. I think that all solids can be divided into smaller pieces because they can get smaller and smaller until they are the size of an atom. I think this because every solid that I can think of that is larger than an atom can be divided into multiple smaller pieces. 5. I think that all different types of solids are made up of different atoms but all solids atoms are all packed together very tightly. I think that they are all made up of different atoms because they all have different properties. 6. I thing that most gases and liquids are made of lightly packed together atoms because they move around a ton so that must mean there atoms are more lightly packed than solids.
