Phenomena, standards, and progressions

Physical Science

The Amplify Science units can be arranged at the discretion of the individual school, but suggested sequences are available. The physical science program in the suggested sequence below progressively builds students’ abilities to meet all the Next Generation Science Standards (NGSS) grade-level performance expectations through a three-dimensional instructional sequence. The following is an overview of the sample sequence of units, a description of the progression of student learning across the year, and a summary of how the sequence meets all NGSS performance expectations for grade 8.

Progression and organization

The units in the physical science course, which occurs at grade 8 in the suggested sequence, are designed and sequenced to build students’ expertise with the grade- level disciplinary core ideas (DCIs), science and engineering practices (SEPs) and crosscutting concepts (CCCs). The year begins with a launch unit, Harnessing Human Energy, in which students are introduced to essential practices, routines, and approaches that will serve as touchstones for learning in all units that follow. An important example of this is Arguing from Evidence. Students are introduced to the practice of scientific argumentation in the launch unit, then build on this understanding through the year, with each unit focusing more in-depth on one aspect of the practice. The Harnessing Human Energy unit also has an emphasis on the CCC of Energy and Matter which students investigate in more depth through the Force and Motion, Magnetic Fields, Thermal Energy, Phase Change, Phase Change Engineering Internship, and Light Waves units.

Concepts and practices are connected across grade 8. For example, students’ understanding of forces develops across the Force and Motion unit (contact forces) and the Magnetic Fields unit (forces that act a distance). Across the sequence of the Thermal Energy, Phase Change, and Chemical Reactions units, students deepen their understanding of Structure and Properties of Matter. The Force and Motion Engineering Internship unit follows the Force and Motion unit and requires students to apply what they learned in the Force and Motion unit to design a solution to an engineering problem. The same is true of the Phase Change Engineering Internship unit and the Phase Change unit.

Each unit has a particular emphasis on certain DCIs, CCC’s, and SEP’s, with combinations that work together to support deep explanations of the anchor phenomenon of each unit. For example, in the Magnetic Fields unit, investigating a surprising result from a test of a magnetic spacecraft launcher leads students to discoveries about Types of Interactions (DCI PS2.B), including magnetic forces; Definitions of Energy (DCI PS3.A); and Relationship Between Energy and Forces (PS3.C). The unit has a particular emphasis on the CCC of Systems and System Models which helps students think about systems of objects in a field. It includes a focus on Planning and Carrying Out Investigations, as these concepts are some of the most appropriate in middle school to discover via experiments.
