Directions: Read each slide carefully and record on your sheet the fact typed in red.

Biosphere Our Earth is made up of all living and non-living things. The interaction of all these building blocks make up the biosphere

Ecosystem Communities of living things interact with non- living things. The air, earth and water play an important role in the building blocks of life

Community All animals and plants that live in one place are considered a community. This can be tricky when you include humans, because they can move from community to community. There are also other animals, such as birds and butterflies that migrate from community to community.

Population Organisms of the same species. All of the coyotes in Arizona. All of the humans in the world. All of the mesquite trees in Ahwatukee.

Individual Individual- Individual people make up the community. Each person has their own individual characteristics that make up the diversity of the community

Organs and Tissues The human body, like most plants and animals is made up of organs. These are the brain, heart, kidneys, liver etc. Each organ is made of different tissues. These tissues have their own characteristics and function. Did you know the largest organ in the body is the skin and that you are not wearing the same skin that you were born with?skin

Cells Tissues are made of cells. The cell is the smallest unit of life. What does that mean? It means that the cell is the smallest living thing capable of replicating.

Organelles Cells are also made up of individual parts. The interior of any cell has many types of little organs- called organelles, for example- nucleus, mitochondria, Golgi complex etc. All these organelles have their own functions to perform within the cell. organelles

Molecules What are organelles made of? All the cellular organelles are made of molecules carbs, Lipids, Proteins, Nucleic acids (DNA, RNA).

Atoms Molecules are made up of even smaller building blocks. Atoms which consist of neutrons, protons, and electrons. There are 92 naturally occurring atoms (also called elements) but only 11 of these atoms are found in a significant amount in living things. It takes only two atoms to make a molecule. elements

Quarks For many years it was thought that the smallest building blocks were atoms, but now we know that it not true. Scientists have found even smaller building blocks than atoms. They have a funny names: quarks. There are many "flavors" of quarks. Their names are - up, down, top, bottom, charm and strange.
