-Four components of soil:
Humus
Sand
Gravel
Clay
-Added different components to water and observed how they reacted in the water. ]]> 2018-02-26 19:10:02 UTC https://padlet.com/mdm272/t3hz4tvip6q3/wish/235570129 mdm272 https://padlet.com/mdm272/t3hz4tvip6q3/wish/235570888 -Poured various components of soil in 30ml of water. Observed what component absorbed the most waterObserved what components water moved more easily through
Read about erosion.
-Gravel let the most water through.
-Humus and Clay had the most runoff]]> 2018-02-26 19:11:04 UTC https://padlet.com/mdm272/t3hz4tvip6q3/wish/235570888 mdm272 https://padlet.com/mdm272/t3hz4tvip6q3/wish/235571202 humus- some of it sunk and the rest stayed at the top.

clay- when it went in water it turned into chunks. i also noticed   that the water absorbed some 
clay.

gravel- in the water it sinks. it also holds the water above it.

sand- when you put the sand in the water it absorbs

cracks-Tresean
-I learned that when you spray water on the soil the soil will 
suck the water in and make it fall apart and wet-Najma

-The gravel sank while the hummus floated because the gravel had more weight and the hummus is more light 
-and there was air bubbles that came from the components of soil because the components most likely has air inside to absorb the water and when it is in water the air escapes in the form of the bubbles

Jose/ adding to Abby and Alivia the water spread ed into the soil and made it darker and more stickier and hard while it goes to the bottom of the project. done!]]> 2018-02-26 19:12:33 UTC https://padlet.com/mdm272/t3hz4tvip6q3/wish/235571988 mdm272 https://padlet.com/mdm272/t3hz4tvip6q3/wish/235572032 Amani/chawn -first we put the gravel in the tube -then we put 30ml of water in the tube -then we saw the gravel sinking then when we poured the gravel water out  -and the gravel had 36ml water poured out and we figured out that clay had that clay had the most water poured 
out.    i think the water that we poured 340

happen  is like ibrahim said  it could not hold the water a loseing the dirt  and rock mostly the dirt and make  the rock fall.]]> 2018-02-26 19:15:27 UTC https://padlet.com/mdm272/t3hz4tvip6q3/wish/235573924 mdm272 https://padlet.com/mdm272/t3hz4tvip6q3/wish/235573947  -BRI-i was think it was caused by the clay layer made everthing fall to caus the landslide.]]> 2018-02-26 19:15:29 UTC https://padlet.com/mdm272/t3hz4tvip6q3/wish/235573947 https://padlet.com/mdm272/t3hz4tvip6q3/wish/237223863 2018-03-01 23:08:32 UTC https://padlet.com/mdm272/t3hz4tvip6q3/wish/237223863 https://padlet.com/mdm272/t3hz4tvip6q3/wish/237224597 Because water could overflow and weaken the soil and since the mud is weakened the mud falls down caused by gravity. ]]> 2018-03-01 23:13:13 UTC https://padlet.com/mdm272/t3hz4tvip6q3/wish/237224597 https://padlet.com/mdm272/t3hz4tvip6q3/wish/237225198 Created a cliff with the soil components
-Sprayed water bottle to act like rain on land.
-Looked at bucket to see the collected "runoff" or the lack of "runoff" collected in the bucket.
-Looked at how much rain occured in the area before and after the landslide in Oso.
-Estimated that there was about 40 inches of rain during the 3 months before the landslide.]]> 2018-03-01 23:16:40 UTC https://padlet.com/mdm272/t3hz4tvip6q3/wish/237225198
