Deep Thoughts on the Matter

Sand is a solid that you find at beaches or in deserts. It is the result of stone that has eroded.

Sand is a solid because each grain of sand is just a very small solid that can hold its shape. When it is poured, the small grains of sand pile up on each other to form a small hill and not a flat surface. Furthermore, it does not completely fill the container like a liquid. While it may appear to do this, there are in fact lots of small spaces between the grains of sand. Each grain of sand is unable to flow to fill these small spaces. As a result, we can carefully pour water into a container of sand without spilling anything over the edge. We are able to do this because water is a liquid that can flow and fill the small spaces between the solid grains of sand.

Sand is a solid that appears to act like a liquid when, in actual fact, it does not.

  1. Since you can pour sand into a cup, why isn’t it a liquid?

2) You can’t usually see gases in the air. How can you observe gases without seeing them?

3) Can you feel water in the air? Explain your answer.

4) Does air have a mass? Explain your answer.

  1. 1) Sand is not a liquid because it is just teeny tiny and very small rocks that have actually come off a cliff which makes them like grains but tiny grains. It is as well pourable but just because the grains of sand are very, very, very small. If it was normal sized rocks, it wouldn`t pour because the rocks would be too big! That is why sand is not a liquid, it is a solid.

  2. 1) Because, each grain of sand is a solid but they don’t will up the whole cup because there is a space between each grain.

  3. 3)You can kind of feel water in the air, but it depends entirely on the density and amount of water vapour, mist or water droplets in the air at the time.

  4. 2) You can hear it and also if you have a straw blow through one end and have your finger at the end of the straw and blow so you feel it.

  5. 3. You can’t feel water in the air unless it is raining then you can feel water in the air but there is no water just floating in mid air.

  6. 3) You normally can’t but when it rains you can feel the water falling down from the clouds. However when it is rising in the atmosphere we can not see it or feel it.

  7. 3) you can not feel water in the air because it is so small when the sun pulls it up so you won’t feel it

  8. 4)Yes. Air has a mass because no matter what shape container or balloon or whatever you put it in,it can occupy all space.

  9. 1) because when you feel the grains in the sand they are hard
    2) feel them and smell them
    3) yes because the clouds are made out of water.
    4) yes because it takes up space

  10. 4) Air does have a mass in our experiment we found out the less air the less mass their is and things fall lighter.

  11. 3) Yes, because everything is sourounded by air which makes rain for example sourounded by air as well. Also you can touch everything and that includes rain water.

  12. 2) You can feel gases whether they are hot or you can feel them when they blow on you. You can also observe them by hearing them.

  13. 3) No, because water is only above us the only time you can feel it is when it rains or something like that.

  14. 3) yes, because sometimes you can feel the humidity and you can sort of feel when it is about to rain

  15. 1) because sand cannot flow like a liquid through tiny holes sand isn’t a liquid because it isn’t drinkable.

  16. 3) You can’t fell water in the air because the water is small and hard to feel but only if it’s raining you can feel it.

  17. 3) Yes, you can do this by either waiting for it to rain and going out in the rain, using a hose in the air and waiting for the water to come down or have a bucket of water in the air and waiting for the water to come down.

  18. 2)we can’t see gases.Some gases are thin or thick all gases go up into the atmosphere causing global warming.

  19. 4)yes,I have even proved by plowing up two balloons and seeing which one falls first and if something falls air has a mass

  20. You can not see a gas but you can observe it because it comes in different types. For example steam is a gas because scientists have observed what it is. They did that by feeling it. You can`t feel it as normal or as if it is a solid, but you can feel the temperature of it with your hand above the steam. That way you can technically observe a gas.

  21. 3) You can’t because water that is in the air is either in the clouds or it was once water but now it is water evaporation.

  22. 4. gases have a mass because if you put gases into a container then it would fall to the floor for example a balloon with hydrogen would float and with oxagen it would fall

  23. 4) Air has a mass and we learnt that because we did an experiment on that exact topic this year.

  24. 3) No. Water is heavy and will not stay in the air if you do that! You can only feel it if it is on the ground because it does not stay in the air like a gas.
