11 lessons//11 Weeks
 Week 1
Lesson 1
The Atom - Subatomic Particles (Proton, Neutron, and Electron)
We will start with the basic building block of matter, an atom! We use different atom models, identify subatomic particles and their charges, and understand how to draw or model atoms of specific elements.
 Week 2
Lesson 2
Atoms, Elements, and Molecules
We will discuss chemical versus physical combinations, pure substances, how elements combine to make new substances (molecules), and the basics of bonding (covalent and ionic bonding).
 Week 3
Lesson 3
Reading the Periodic Table of Elements
We will discuss basic vocabulary associated with the periodic table of elements, such as atomic number, atomic mass, and chemical symbol. We will also practice calculating the number of protons and neutrons in a specific element and then discussing groups and trends in the periodic table.
 Week 4
Lesson 4
Density and Other Physical Properties - How to Identify an Unknown Substance
We will practice identifying elements using their physical and chemical properties, such as density. We will spend more time on density, what it is, calculate it, and use it to identify elements and compounds.
 Week 5
Lesson 5
The Law of Conservation of Mass and Balancing Equations (Basic)
We will discuss chemical equations, the law of conservation of mass, and balance simple equations. Your student may want a manipulative such as candy (Skittles, M&M's, or multicolor candy) or beads for this activity.
 Week 6
Lesson 6
Lewis Electron Dot Diagrams
We will use our knowledge of the outermost energy level (valence shell) to create Lewis Electron Dot Diagrams! This shorthand model is used to show ionic and covalent bonding. It emphasizes the attraction between valence electrons in bonding.
 Week 7
Lesson 7
The Unique Properties of Water
We will explore the polar nature of water. Water is a neutral molecule with slight charges due to its oxygen and hydrogen arrangement. This gives water some fascinating and unique properties that we will explore together in this lesson.
 Week 8
Lesson 8
Dissolving – Solids, Liquids, and Gases
We will investigate how different types of liquids dissolve specific kinds of molecules. We will examine how and why water, oil, and alcohol dissolve differently. Students will have the opportunity to watch demos and explore these properties on their own at home.
 Week 9
Lesson 9
Chemical Reaction Review
We will review a chemical reaction and chemical equations. We will look at controlling the number of products. We will analyze the reaction of baking soda and vinegar with differing amounts of reactants.
 Week 10
Lesson 10
Exothermic and Endothermic Chemical Interactions
We will discuss how the interactions between atoms, ions, and molecules can take in or release heat when they come together. Students will learn molecular reasoning for absorbing or releasing energy. They can predict whether a reaction will be endothermic or exothermic.
 Week 11
Lesson 11
Acid-Base Reactions
We will explore acids and bases. We will learn what makes a solution more acidic or basic and the properties of acids and bases. We will use this information to discuss neutralizing acids and bases and their real-world applications.

  • At the end of this course, your student will be able to: - Create models/drawings to represent the arrangement and charges of subatomic particles in an atom (protons, neutrons, and electrons). - Distinguish between atoms, elements, molecules, and compounds. - Use atomic mass, atomic number, and symbol to determine an element's placement on the Periodic Table. - Investigate the property of density and provide evidence that properties such as density do not change for a pure substance. - Balance chemical equations to show how the total number of atoms for each element does not change in chemical reactions, and as a result, mass is always conserved in a closed system. (Law of Conservation of Mass.) - Create Lewis Electron Dot Diagrams for elements and compounds. - Describe the bonding differences between ionic and covalent bonds. - Explain the polar nature of water and describe how it gives it unique properties. - Investigate the properties of different substances and how they affect their ability to dissolve. - Using the reaction's chemical equation, identify what will cause a reaction to release (exothermic) or absorb (endothermic) energy. - Describe what makes a substance acidic or basic and how to neutralize those substances.
