Students went outside and collected local soil from 3 different locations around the school yard to compare to our homemade soil.

Students began investigating soil. We made soil in our class with pebbles, gravel, sand and humus. We discovered that humus attaches itself to everything and cannot be separated out.
Students learned how bricks are made, how rocks are polished and how we use rocks in our daily lives.
Students observed another use of rocks in sandpaper. We observed fine, medium and coarse sand paper.
Today we walked around outside the building looking for examples of boulders, cobbles, pebbles, sand, silt and clay and how those sizes of rock are used around the school building. We found lots of examples of how humans use rocks.
Students observed their clay in vials with water and their clay balls that were left out on the counter.
Students explored clay and learned that clay is the smallest sized rock. We put clay in vials to shake it in water and we left some clay out in the air.
Students earned a free day for good behavior. They chose to play kahoot games reinforcing the content we are learning in our rocks unit, similar and different properties and graphing skills.
Students observed the sand in the vial we let set in water over the weekend. We saw that there is a smaller sized rock than sand called silt.
Students investigated sand. Sand is a size of rock, not a type of rock. We observed water soaking into the sand and then we shook our vials and saw the sand settle out.
