waves and change them into signals that our brain can understand. I would mark that the
ear is made up of three different parts, but I already know that. I already have it written
down. 2
nd
paragraph – Read – I will mark ear flap, ear canal, ear drum and membrane.
This whole paragraph is important. 3
rd
paragraph – Read – I will mark hollow cave, 3
bones- hammer, anvil, and stirrup. I should also mark that the stirrup makes the oval
window vibrate. 4
th
paragraph – Read – I will mark cochlea, vestibule, and semicircular
canals. Cochlea – three tubes, filled with fluid. Oval Window vibrates, it makes waves
in the fluid. Hairs in the tube prompts nerves to carry messages about sound to your
brain. 5
th
paragraph – Read – mark, semicircular canals help you keep your balance.
Fluid and hairs let the brain know has happened. Vestibule contains two sacs filled with
fluid and sensitive hair cells. Chalky particles inside them, pulled by gravity. Particles
press on the hairs at the bottom of each sac. Nerves from the hairs signal your brain
about the position of your body. I got a lot of information from the text, but these
pictures are great too.
Okay. Where am I now? Step four is O, which stands for Outline. I know how to
outline; we went over this. If I need to I can use the wall chart as an example. My
Outline needs to include headings, major ideas, and supporting details. When I am
writing my headings I should try and outline them with out looking back at the text. If I
can remember it now I will have a much better chance at remembering it later. Let see,
my first heading is the Title – How do you hear? – I remember that the ear is an organ
made up of three different parts, listed below. The ear converts sound vibrations to
signals that the brain can understand. Outer - The outer ear has an ear flap, ear canal and
eardrum that is made up of a sheet of skin. Middle- Three bones that hit each other,
hammer, anvil and stirrup, and the stirrup vibrates the oval membrane. Inner- cochlea
looks like a snail and has fluid and tiny hairs that vibrate when the oval window vibrate
and that sends signals to the brain, then there is the vestibule and semicircular canals.
Balance- the semicircular canals are filled with fluid and hairs that move with the
movements of the head, and send messages to our brain and help us balance. The
Vestibule has two sacs filled with fluid and chalky stuff that is pulled down by gravity,
and lets our brain know what position our body is in.
The last step, I am almost finished! L. L stands for Look back. Now I need to check my
memory, and look back to see if what I outlined was accurate. If I did write down
something wrong, now is the time to change it. Since I marked my text this should be
easy. Let’s see . . . Wow, I really remembered well. I worded some things differently,
but I have the same information. YIPPEE!!!!
Once modeling has been completed, the student will be asked to discuss what they
thought. Do they think this will be something useful for them, and why or why not.
How well do they think they will use the strategy? What would they have done
differently? Do they have any questions about what I did?
