This is a 4-page unit test for a typical middle school chemistry unit on the structure of the atom, elements, and the periodic table.

This test is designed to take the average science student 35-45 minutes to complete.

Concepts Addressed in This Test:

  • What is an atom
  • Basic a structure of an atom
  • History of atomic science (e.g. Democritus, Dalton, Thomson, etc.)
  • Atomic number
  • Mass number
  • Isotopes
  • Development of the periodic table (e.g. Dmitri Mendeleev)
  • What each element square shows
  • Names and chemical symbols of elements 1-36
  • Metals, nonmetals, metalloids
  • Groups of the periodic table
  • Patterns in the periodic table

All of my tests follow a similar format and are divided into the 3 sections summarized below.

Part A: Knowledge: (~ 60% of the Test)

  • Questions that involve simple recall of facts from the unit
  • Typical questions include modified true/false, fill in the blanks, definitions, summary tables, labeling, short answer
  • Modified true/false of key classification of matter vocabulary terms
  • Labeling a diagram of the atom (electron cloud model)
  • Matching the names of different scientists with their contribution to atomic theory
  • Calculating the # of protons, electrons, and neutrons from atomic number and mass number
  • Recalling the name or chemical symbol of elements 1-36 (only 12 questions in total)
  • Identifying groups of the periodic table
  • Comparing and contrasting different isotopes of the same element
  • Determining which isotope is most abundant based on mass number

Part B: Skills: (~ 30% of the Test)

  • Questions that involve performing particular skill(s) taught during the unit
  • Typical questions involve summary tables, graphing, analyzing graphing, identification exercises
  • Identifying what periodic table group 5 unknown elements should belong to based on properties
  • - Using periodic trends to explain how one compound reacts similar to another

Part C: Application: (~ 10% of the Test)

  • Questions that involve using prior knowledge and applying it to a brand-new situation or problem
  • Analyzing an "alien" periodic table (with different names and symbols of the same elements)
  • Determining relationships between different elements based on their positions in the alien periodic table

Other Features of This Test:

1. Linked to Key Unit Documents

Each of my tests are linked to two supporting documents. Firstly, a Unit Overview & Key Words document that I distribute at the start of the unit, which introduces main ideas, essential questions, skills, vocabulary terms, and relevant resources for the unit of study.

Unit Overview & Key Words - Atoms and the Periodic Table Unit

Secondly, a Unit Review document that I distribute 3-4 days before the test that helps students review the main concepts of the unit. The test is designed so that some questions are similar, if not exact copies, of questions found on the Unit Review. In this way, students that complete the Unit Review and check their answers should directly benefit from their efforts!

2. Student-Focused Post-Test Analysis Section

All of my tests feature a Post-Test Analysis box on the first page. After receiving their graded test with the overall score, students are then instructed to calculate their % score for each of the 3 sections listed above. This allows students, parents, and teachers to breakdown student performance into (1) content recall; (2) skill mastery; and (3) application of knowledge. There is also a designated place for a parent signature, if desired.

3. Hidden Instruction for Bonus Points!

Each of my tests contains a hidden instruction that rewards students who read the test carefully and follow instructions with 1 bonus point. For example, there may be a hidden instruction at the end of a set of instructions that says, "Draw a model atom to the right of your name". In my experience, students love to search for these on my tests, as it is a quick and clear reward that is based on good test-taking habits. At the same time, it encourages students to read the test document thoroughly. Everyone benefits!

4. Complete Color-Coded Answer Key

All of my tests feature a complete answer key that can be used to grade the test but also to show to students after they receive their graded test documents back. My answer keys are designed to be specific, but offer grading flexibility on longer answers. Since the test document is a Word file (.docx), the answer key is fully customizable if you wish to make it match your own curriculum more closely.
