  1. Solid's are- Rock, Foam Rubber Ball, Sponge, Wood, Baby, Styofoam, Iron Nail, Cotton Ball

    The reason is I think that these are solids are because you can't see through the object's. That is why these are solds.

  2. i domt think a powder is a solid niether a sugar does anyone else think so

    ReplyDelete
  3. Make sure you explain your "rule".

    ReplyDelete
  4. Jackson-I think that your wrong because glass is see through and it is still a solid

    ReplyDelete
  5. Well, I think that that the rock, the wood, and the fether are solids, but what do you think about the melting wax? I mean It is melting right, but it say it is melting so half could still be there it never said if it melted all the way.

  6. Rock, feathers, rubber bands, cloth, foam rubber ball, sponge, wood, styrofoam, iron nails,cotton balls. I am sure that these are all solid. Because solids are thing that you can hold in your hand with it not falling out eaisly. thing like sugar. baby powder, soil and dust I am pretty sure that those are solids but I don't know. Because they are not like liquids. A exmple of a liquid is milk and those things are not like milk. I guess that those are solids because each litte thing of sugar and those things are made up of little tiny solids? Agree with me anybody?

  7. I think that rocks,wood,and ice are a solid because you can hold it. I also think that baby power, and milk is not soild beacause you can't hold it.

  8. We'll I'm sorry I make a mistake

    ReplyDelete
  9. Obviosly a rock is a solid, And I know wood and ice are solid. You are right about the others too Ryan.

    ReplyDelete
  10. Georgia I agree with you I also think a glass is a solid to. I think it is a solid because it is hard and does not form into a different when it is put into a jar.

    ReplyDelete
  11. I'm sorry Rylan I called you Ryan.

    ReplyDelete
  12. Wait baby powder is a solid because it is not a liquid or gas.

    ReplyDelete
  13. I think that milk is not a solid because it can pour into a substance and has a and takes the shape of that substance. a solid is like a rock that stays the same shape all the time. I aggree
    with Georga .L because milk is a liquid no a solid!

    ReplyDelete
  14. Glass is a solid too. If you don't think so prove to yourself that glass is a liquid or gas. In a form glass is a liquid but not when we usually see it. Mary Ann you are correct.

    ReplyDelete
  15. Mary Ann I agree with you because glass,rock, or anything that's solid is hard so it does'nt really make a diffrence if you just put it into a jar because nothing is so scientific or intresting of a ordanary jar! Its very boring and does ABSOLUTLY nothing! So yeah I agree with you Mary Ann.

    ReplyDelete
  16. Would dust be a gas or a solid? May somone comment.

    ReplyDelete
  17. I think that rocks,feathers,wood,ice,nalis,and a ball,are solids because there moliculse are pressed to gether tightly,and can not move,so there for it is solid.

    ReplyDelete
  18. Hay Jackson I agree. I also think an iron nail and a peice of wood is a soild to. I think a cottion ball is consitterd a soild to because you can hold it un like milk.

    ReplyDelete
  19. they are all solids exept the melting wax,milk and air

    ReplyDelete
  20. solids are something you cn hold

    ReplyDelete
  21. glass started as a liquid and was molded into a sloid

    ReplyDelete
  22. I think it is a solid because gas is like steam and it is more likely for it to be a solid.

    ReplyDelete
  23. Hey Daniel A. I think you forgot to put cooking oil.

    ReplyDelete
  24. What about the iron nail. It was made out of a hot liquid.

    ReplyDelete
  25. I agree but what is it when you see it?

    ReplyDelete
  26. I think that most of them are solids except for milk and melting wax which I think are liquids and air which is a gass. Any comments?

    ReplyDelete
  27. What do you think about the melting wax?

    ReplyDelete
  28. I love seeing our students use capitalization rules when they write about science!

    ReplyDelete
  29. I think an iron nail is a solid. She is not talking about before they make it, she is talking about a regular iron nail.
    Does anyone agree?

    ReplyDelete
  30. Milk is not a solid it is a liquid but a rock,wood,foam rubber ball,ice,feather,iron nail,rubber band,cloth,and cotton ball's.

    ReplyDelete
  31. I dont think powder, sugar, or flour is a solid I kind of think its a gas.

    ReplyDelete
  32. Well, why do you think that Seth?

    ReplyDelete
  33. I think Melting Wax is a liquid because because its runny

    ReplyDelete
  34. Most of these are solids except air, cooking oil, melting wax, flour, baby powder, sugar, salt, and dust

    ReplyDelete
  35. I think Asaad because it doesnt look like a solid.

    ReplyDelete
  36. I think its a solid beause salt,sugar and powder have cristals that are tiny enough that you cann't see them. But since crystels are considered as solids thay count.

    ReplyDelete
  37. I think baby powder, sugar, salt, and dust are solid.

    ReplyDelete
  38. Well it doesnt just fit right that it is a solid

    ReplyDelete
  39. I think melting wax, air,cooking oil,milk is not a solid but evrything else is.

    ReplyDelete
  40. I agree with georgia

    ReplyDelete
  41. OK, I'm thinking about the comment someone said about a liquid being something that can be poured into another object and take that object's shape. Wouldn't salt or sugar take the shape of an object that it is poured into? But I don't think of salt and sugar as a liquid. Does our definition of a liquid need to be refined? Ms. Kleb

    ReplyDelete
  42. I wonder if some items can take different forms of matter? If you melt sugar, it becomes a liquid. When it cools, it becomes a solid. Makes me think that Georgia is on the right track. I love all the thinking and sharing going on. This is a worthwhile assignment.
    Keep up the good work- Mrs. Harn

  43. I think Rocks
    rubber bands feathers cloth baby powder
    sugar foam rubber ball Styrofoam
    flour dust
    sponge iron nail
    ice wood soil
    melting wax salt cotton ball
    are all solids

    ReplyDelete
  44. Hey Asaad dust would be a solid.

    ReplyDelete
  45. Well, yes the bigger the object is it takes up more space right? I am pretty sure that is right. Because a cup of sugar is less than 1 block of wood.

    ReplyDelete
  46. Sam I think you are right. Josh I agree with you to.

    ReplyDelete
  47. I agree Samuel.

    ReplyDelete
  48. Do you think there is a way to melt salt? What other things can you come up with that you can have melt that is already a solid?

    ReplyDelete
  49. I think ice, cooking oil, melting wax, and milk are all liquid, but i think ice can be a solid and liquid because it melts in heat also with the melting wax because it is hard and the wax melts when lighted.

    ReplyDelete
  50. YOU can melt styrafoam and salt to.

    ReplyDelete
  51. I want to answer some questions. Does anyone have any?

    ReplyDelete

    ReplyDelete
  58. Kaitlyn- Sorry if I said it was a solid I was trying to say a example of a liquid

    ReplyDelete
  59. And Claire I agree with you about the melting wax

    ReplyDelete
  60. yes Emma I agree with you. I think a iron nail and a pice of wood is a soild to. I also think a rock is a solid because it is hard.

    ReplyDelete
  61. Hey. My post didn't show up?
    I think the only things that aren't solids are milk, air, melting wax and cooking oil. Some things on the list can be solid or change to a liquid when exposed to heat like ice and sugar. I hope it works this time!!!!

    ReplyDelete
  62. I think milk and cooking oil are the only substances that are not solids because they can take any form and be poured. Solids have a set form.Wax is on the border of a solid and liquid because it can hold its shape, but it is soft without having air inside of it.

    ReplyDelete
  63. The soild's are rock,feather,ice,sugar,clost,salt,wood,sponge,foam rubber ball,rubberband, dust,baby powder,iron nail,soil,cotton ball and styrofoam.

    ReplyDelete
  64. Hey Warren you cant melt salt but you can disalvie it

    ReplyDelete
  65. Hey Niki what about melted wax

    ReplyDelete
  66. Sugar,salt,soil,baby powder,dust, and flour are also solids.

    ReplyDelete
  67. I agree with Colter

    ReplyDelete
  68. I agree with you Nicole.

    ReplyDelete
  69. I really love the discussion! YEA!
    Is it fair to say that all liquids have to be wet? Would that rule work?

    ReplyDelete
  70. What about smoke or a cloud? Are they gas?

    ReplyDelete
  71. what about ice and cloth

    ReplyDelete
  72. Ice and cloth are solids.

    ReplyDelete
  73. Yes mam thay are gasses

    ReplyDelete
  74. Smoke and clouds are gasses

    ReplyDelete
  75. Smoke and clouds are gases but a could is made up of water so would you really count it as a gas?

    ReplyDelete
  76. about 90% of the body are liquid

    ReplyDelete
  77. Well a liquid is runny so I can't think of a liquid that is not wet. Can you think of one?

    ReplyDelete
  78. I dont think there is any liquid thats not wet.

    ReplyDelete
  79. Warren- I do agreed about the a feather is a solid

    ReplyDelete
  80. Thare is not a liquid that is not wet

    ReplyDelete
  81. ??? I think that the solids are the rock,feather, and the wood and (ect.) but im with Warren on this one and its about the multing wax.it goes on liquid first bit then it turns hard.... :( im confused!!!

    ReplyDelete
  82. Kelsie- Don't feel overwelmed. It is okay to just get the ideas out. Don't worry about right answers right now. :)

    ReplyDelete
  83. Well wood is definently a solid so is a feather and rock. So yeah warren is right.

    ReplyDelete
  84. I think these are all solids rock,feather,sugar,ice,rubber band,cloth,foam rubber ball,flower,sponge,wood,baby powder,Styrofoam,dust,iron nail,cotton ball. i think all of those are solids.

    ReplyDelete
  85. Mrs. Charles- I do agree about that clouds and smoke are gas, but those are not solids.

    ReplyDelete
  86. Joshua Miller- I do agree about all your solids

    ReplyDelete
  87. I think everything in the list is a solid except for milk, cooking oil, and air.
    But with melting wax half can be a solid and
    half can be a liquid. I think the melted wax is
    a liquid becuase it will take the shape of the container it's put in and the non melted I see as a solid.

    ReplyDelete
  88. Ya I am right. Cool.

    ReplyDelete
  89. Yes I agree about that, that all liquids are all wet.

    ReplyDelete
  90. Hey is any one on?

    ReplyDelete
  91. Warren- Yes you are wright again!!!!!!!

    ReplyDelete
  92. I agree with Melanie because sugar and dust are solids. But there is so many of them and there so little that alot of them will fill not take the shape but fill up a container because its a solid.

    ReplyDelete
  93. I dont think dust is a solid Josh

    ReplyDelete
  94. Ya I am on a roll!

    ReplyDelete
  95. Why? I think it is a solid?

  97. Because it is not something you could drink you would eat it if so.

    ReplyDelete
  98. Wait what do you think Jackson? Is dust a solid?

    ReplyDelete
  99. Now I have to go.

    ReplyDelete
  100. I know that baby powder is not a solid, because solids are usually hard and baby powder isn't even close to being hard.

    ReplyDelete
  101. No. I do not agree on that. It is not a liquid because all liquids will get you wet, and it is not a gas,so it has to be a solid.

    ReplyDelete
  102. I agree with Warren.

    ReplyDelete
  103. I agree that babby power is a liqid becaus if you poured a glass of of water on it would becaus a liqid

    ReplyDelete
  104. think suger,babypowder,salt,flour and dust are
    solids.Because like warren said liquids make you
    wet.And gases like air you cant see.So suger,babypowder,salt,flour,and dust are solids.

    ReplyDelete
  105. I think sugar, baby powder, salt, sugar, dust, flour are solids. They are strange to be solids,but there not either liquid or gas. So I think they are solids. Milk and cooking oil are examples of liquids. Air is a gas.

    ReplyDelete
  106. I think a rubberband is a soild because it doesent take the shap of a object if you put it in

    ReplyDelete
  107. i agree with jaiken

    ReplyDelete

    ReplyDelete
  110. Hey guys -- here is something I just found on the web. Looks like a cloud is a liquid, not a gas.

    "Clouds, snow, and rain are all made of up of some form of water. A cloud is comprised of tiny water droplets and/or ice crystals, a snowflake is an aggregate of many ice crystals, and rain is just liquid water."

    ReplyDelete
  111. Dylan post this on the is it a solid part 2.
    We started the discussion there. :)
