Amplify 

Each course (or “year”) of Amplify Science for grades 6–8 consists of nine units. An example of how the units can be distributed amongst each of the grade levels is provided here, but schools have full discretion to order the units into any sequence that is appropriate for their district. Each unit contains 10–19 lessons,  each of which was written for a 45-minute session — though teachers can expand or contract the timing to meet their needs. The number of lessons in a unit depends on the unit type, which is explained in more detail below.
