Hello Friends, Hi Jerri!
I just finished watching "What is life?". I agree! I am going to
learn a lot too. It was great watching the kids struggle and have the
discussions over living, dead and non-living. I am teaching these
lessons right now in my own classroom and plan on doing this same lesson
tomorrow. We started our by brainstorming how scientists classify all
things on earth and they came up with the three headings (with a little
guidance) and we listed some things that would go under each category
and they immediately began to list animals under living, Leaves and dead
animals and people under dead and inanimate objects such as chairs and
lunchboxes under non-living. Then I asked them about a shell and many
were uncertain. We talked about that for a good ten minutes. So
tomorrow I am going to try the sorting activity with them.

My definition of Life before I watched the video was similair to a
child's.
 Living things eat, breathe, grow and change, reproduce and die. Not
too scientific huh?
My new scientific version is:
Living organisms are all comprised of cells which are the single
subunits that where all fundamental processes take place. Cells are
comprised of organic molecules that continue to build and fuel the
living organism. Because they are made of cells, living things require
energy and fuel to rebuild and sustain life in thier cells. All living
organisms respond to changes in their internal and external
environments. The cells of living organisms contain hereditary
information, strings of organic molecules called DNA.

Has anyone started the bottle biology section? I have attempted to put
the eco-column together, This I am not so sure of yet:)

Looking forward to hearing from all of you, I enjoy reading everyone's
response!
Kim

Hi classmates!
response to question

What is Life?
Life is a unique chemistry interaction that reveals characteristics
that
have not been observed in the same complete combination in any
other chemical state.
The definition of life is explored and clarified as the video
progresses.
Students explore the implications of their impressions.
The elemental chemicals involved with life are Oxygen, Carbon,
Hydrogen, Calcium, and Phosphorus.
The world/earth/universe consists of much more than "Life".
Living, Dead, and Non-living.
1. Living things obtain and use matter and energy. 2. Living things

evolve, mature, and progress through their Life Span. 3. All living

things have the potential to reproduce more of their kind. 4. All
living
things have DNA. 5. All living things respond internally and
externally
too stimulus from their environment.ALL 5 components must be
present to constitute life.
I am going to learn a lot!!! Primarily expression of understandings!
