Studying the nature and behavior of matter by experimenting with heat, solutions, and electricity. We will also analyze the periodic table to determine the reasons for its existing organization.
All that Matters
1.1.1. Understand the atomic nature of matter, how it relates to physical and chemical properties and serves as the basis for the structure and use of the periodic table.
Identify an unknown substance using the substance's physical and chemical properties.
TOPS Analysis
Explain and predict the behavior of a substance based upon the substances atomic structure, physical properties, and chemical properties.
TOPS Analysis
TOPS Solutions
Describe the properties of electrons, protons, and neutrons (i.e., electrons have negative charge and very little mass, protons have positive charge and much mass, neutrons have neutral charge and the same mass as protons).
TOPS Electricity
Explain how changing the number of electrons, neutrons, and protons of an atom affects that atom, including atomic name, number, and placement on the periodic table.
Explain the similar properties of elements in a vertical column (groups or families) of the periodic table.
Predict the properties of an element based on the elements location (groups or families) on the periodic table.

1.2.3. Understand the structure of atoms, how atoms bond to form molecules, and that molecules form solutions.
• Describe molecules forming a solution (e.g., salt added to water dissolves, forming a salt water solution, until saturation when no more salt will dissolve).
TOPS Solutions
TOPS Rocks & Minerals
• Describe how to separate mixtures and or solutions of several different kinds of substances (e.g., sand, sugar, iron filings).
TOPS Analysis
• Describe the structure of atoms in terms of protons and neutrons forming the nucleus, which is surrounded by electrons (e.g., a helium atom usually has a nucleus formed by 2 protons and 2 neutrons, which is surrounded by 2 electrons).

• Describe how atoms bond to form molecules in terms of transferring and/or sharing electrons (e.g., sodium atoms transfer an electron to chlorine atoms to form salt).
