Learning about Soil

"Changes Under the Ground"

WE MAKE AN EXPERIMENT   

• First, we worked with some of the soil students brought and spread it over a paper. Using the magnifying glass they looked at it and wrote down what they saw there
•

Then, using the jar and putting some soil inside, we poured some water in it and shake it. We watched what happened and students took down notes about it. 

• Finally, we left the jars aside for a few days for the soil to settle down at the bottom. Students could then observe the humus floating at the top.
