Designed by Chadwick Harvey, Earth's Atmosphere Unit Test is specifically designed in accordance with North Carolina's 7th Grade Essential Standards for science. However, this test may also be used to assess students on their knowledge of Earth science at either the middle school or high school level. In addition to assessing students on their knowledge of science, the test is also designed to meet the demands of the common core literacy standards which require students to use strong critical thinking and problem-solving skills. In addition to the unit test, you may also use three review games I have created at www.reviewgamezone.com to help students prepare for the unit test. The codes are 15628, 15629, and 15630.
