All living things are divided into pieces called cells.
Most cells are so small, you need a microscope to see them!
Cells have all the information living things need to grow and change.
Cells There are many kinds of cells that do different things. There are plant cells and animal cells. Click the picture for a short video showing all kinds of cells moving around inside your body!
Animals get nutrients from the foods they eat.
Nutrients are the vitamins and other good stuff that living things need to grow and stay healthy.
Plants get nutrients from soil.
The plant reacts to the sun, water and air.
How do you know the plant reacts to these stimuli?
The environment is the place where something or someone is.
Right now, your environment is school.
Later, your environment will be home, soccer practice, or maybe the store.
A tree’s environment is the forest.
In what environment would you find a fish?
Where would you find a book?
Things that do not:
react to stimuli
eat, need air, nor use nutrients
grow and change
make more of themselves
are non-living .
These are things that were once alive, but are not anymore.
They do not take in nutrients, or grow and change anymore.
Some examples are wood and paper.
Potential For Life
Some things COULD be alive if the conditions were right.
One example is a seed. The seed itself is not living UNTIL it is in soil with water and sun. THEN it becomes a living thing that grows and changes, takes in nutrients and responds to changes in it’s environment.
