Day 1 of Science this week is all about being soil
detectives. Mrs. Galloway set up four dry samples of soil from a river basin,
desert, mountain, and forest. The students viewed the samples using hand
lenses and described the soil using their vocabulary words pebble, gravel,
sand, silt, and clay. They also observed the soil sample in water to help
differentiate the dead plant matter, humus, floating on top. They made a
drawing of their observations and came up with a conclusion based on their
observation. These soil mysteries were
solved thanks to great scientific investigation.
