Fourth Graders learn how geology and biology create soil, which is the living part of our earth that feeds and nourishes up by providing grain for much of the meat we eat and the soil produces fruits and vegetables. This is called "Biogeology." Students explore the small organisms that allow this to happen called decomposers. they learn in more detail about how natures creates soil. They also explore soil and its geological ingredients including minerals used in plants to grow. They work in the garden with the compost they created in the long term experiment. HINTS ON TEACHING FOURTH GRADE GENERAL ADVICE 1. Introduce yourselves, usually children like
to have either Dr, Mr, Miss, Mrs, Ms before your name If you
have a difficult last name you may want to just use your first name.
Tell them how excited you are to be with them, but state the rules, clear
and distinct.
a. Student should raise their hand to be heard. 4. Speak slow and distinct, especially if
English is not your native language. Try to be expressive with your
speech. 11. When students are working on lesson, let
them try to figure things out on their own. Try to find the source
of their problem. First give them hints if they cant make something work.
Be sure to demonstrate what you want them to do. 12. Don't hand out things ahead of time.
wait until you have explained what to do and shown the model. Tell
them not to start until you tell them to. 13. Prepare things so there are materials
for 1 to 2 students. Older students can share as long as they have
something in their hand. Young children (Kindergarten to First) cannot
wait or share well. 15. Do not always call on the same
students. Encourage participation of all students.
