Science Experiment-What makes healthy soil?

                                                                      Project 1:
                               We used shredded carrot, lettuce, plastic bag scraps, and soil
 
Cover the items in soil and put the lid on the plastic container.
Questions: 
What do you think will happen?
  Which items will decompose and which items will remain?
What happens when items decompose?
 
(This photo is taken after a week).
Explain that compost is made when the nutrients from the lettuce and carrot combine with the soil, this is healthy for the earth, but the plastic bag will remain for years.
Have your children make predictions on what will happen after a week. Olive was happy that her predictions turned out to be correct.

We are linked up with ABC & 123!
