Motivation: Demonstrate a piece of bread and cardboard to the class.If you had to choose between bread and cardboard which one would you eat?Why? Nutrients are the substances that an organism needs for energy, growth, repair, or maintenance.

Have students work in groups. Each group develops a group question after solving given problems.

Nutrition is the process by which organisms take in food and break it down so it can be used for metabolism.Metabolism is all the chemical reactions occurring within the cells of an organism.Key questions:1-How does an atom balance the electron of the same atom? Or why does an atom have a electrical charge of zero?2-Where is the nucleus located?3-What does a nucleus contain?4-What is the electrical charge of a proton, electron, and neutron?5-Where is an electron located?6-How do we determine the different types of atoms or elements?7-How can we determine the mass number or weight of an atom?8-Where is a proton located?

-Everything that is living and non-living is made of atoms.-There are many different types of atoms that make different things.-Chemistry is the mixing of different atoms to make something.-Metabolism is all the chemical reaction in a cell.-Inside the cell is a “complex chemical factory”.-The chemical factory is made of atoms, element, molecules, and compounds.-The nucleus is at the center of the atom.-The nucleus is made of proton(s) and neutron(s).-The nucleus has an electrical charge that balance or cancell the electron electrical charge. -Outside of the nucleus are electron(s), that have a negative electrical charge (-).-The proton(s) in the nucleus has a positive electrical charge(+) and the neutron(s) has no electrical charge.-“Atomic number” is the amount or is the number of protons for a particular element.-“Mass number or weigh” is the weight of proton(s) and neutron(s) together for that particular element.

Have students work in groups. Each group develops a group question after solving given problems.

-Element is all the same atoms that have the same number of proton(s) or atomic number. Thus, different elements have different amount of proton(s).-Element is made by all the same type of atom. -An element is represented by a letter or symbol.-All atoms that belong to the same element have the same atomic number.-O2 is one element and two atoms.-H2O is two elements and three atoms.

-A compound is more than one atom or element of the same or different types bonded (held or hold) together.

-A molecule is the smallest particle of a group of the same element or different elements held together to form a compound, that is capable of movement.

-The number behind the symbol indicates the quantity of atoms.

-Ion(s) can be an atom, molecule or compound that has gained or lost an electron. The ion has an electrical charge.

Example:

1)H+ the hydrogen ion has lost an electron.

2)OH- the hydroxyl ion has gained an electron.

-A chemical bond that is formed when atoms lose or gain electrons in their shell or orbit and bonds with

another atom is called an ionic bond. It (compound) has an electrical charge.

-Covalent bonds are formed when atoms produce compounds by sharing electrons in the proper shell or orbit without forming an electrical charge molecule.

-Each shell or orbit of an atom can only hold a certain number or quantity of electron(s).

-A chemical formula shows the numbers and kinds of atoms present in a compound.

Have students work in groups. Each group develops a group question after solving given problems.

-A formula that shows the numbers, kinds and arrangement of atoms is called “structural formula”.

-Explain the difference and similar between “chemical and structural formula.” Write your answer.

-The difference between the structural formula and chemical formula is that the structural formula indicates the arrangement (placement) of the atoms in the compound.

-Equations are used to describe chemical reaction.

-Reactants are the first part used in a chemical reaction to make something (or product).

-Product is the finished part made from the reactants in a chemical reaction.

-Word equation use words to describe the atoms, molecules and compounds in a chemical reaction.

-Chemical equation use symbols and numbers to describe the quantities of atoms, molecules, and compounds.

-Explain the difference between reactants and product or How are reactants different from product in a chemical reaction?

-Explain the difference and similar between a word equation and chemical equation. Or
