Product Description
This document contains six different versions of an acid and base test, all six test keys, and one compilation test key with all six test answers. The test should take anywhere between 30 - 35 minutes depending on the skill level of your students. Each test has 15 questions - 9 questions on basic properties and identification of acids and bases and 6 questions on neutralization reactions.

Content Covered on Test:

Students are asked to...
(1) name common acids and bases they might find in a grocery store
(2) what color acids and bases turn when exposed to litmus paper and phenolphthalein
(3) what pH values acids, bases, and neutral substances have
(4) predict whether a substance will be acidic, basic, or neutral based on what they know about 1 - 3 above
(5) compare pH values to determine if a substance is more/less acidic or more/less basic than another substance
(6) write a word equation for a neutralization reaction
(7) balance, write the formula and phase of the salt formed, and name the acid, base, and salt in a neutralization reaction

Suggested Grading (See FREE PREVIEW for Reference):

For questions 1 - 10, students should receive two points for a correct answer, one point for an incorrect answer, and zero points for no attempt.

Questions 11 - 15 should be graded in three sections. [Section 1] Balancing the reaction - students should receive two points for the correct balancing of the entire reaction and zero points for incorrect balancing. [Section 2] Formula and phase of salt - students should receive two points for a correct formula and phase, one point for an incorrect formula and/or phase, and zero points for no attempt. [Section 3] Naming of the acid, base, and salt - students should receive two points for a correctly spelled name, one point for an incorrect name, and zero points for no attempt.

This would make the entire test out of 122 points. Take how many points a student gets and divide it by the total points possible to get a percentage grade out of 100. (Example: Student Points Earned = 113, Student Points Possible = 122, Percentage Grade = 113/122 x 100 = 93%)

I have found that this grading system works best because it encourages students to attempt every question. Even if students are completely wrong on every question, they can at least get a 50% which looks a lot better than making a 0%. Also, if a student makes no attempt, parent-teacher conferences are more in your favor because you can ask a student why they chose to not even try to answer a question to get partial credit.

To Save Paper:

Each test is two pages in the document. Simply print out each test where the first part of the test will be on the left-hand side of the paper and the second part of the test will be on the right-hand side of the paper. This document contains 12-point Times New Roman Font which will remain easy for students to read once shrunk.

*All tests are fully customizable and any material you don't cover can be removed and replaced with those that you are.
