OpenSciEd Unit 8.3: Forces at a Distance Student Workbook

OpenSciEd Middle School science program addresses all middle school NGSS standards. This comprehensive science curriculum empowers students to question, design, investigate, and solve the world around them. 

• Phenomenon Based - Centered around exploring phenomena or solving problems
• Driven by Student Questions - Storyline based on students’ questions and ideas 
• Grounded in Evidence - Incremental building and revision of ideas based on evidence 
• Collaborative - class and teacher figure out ideas together
• Equitable - Builds a classroom culture that values ideas and learning of all

The OpenSciEd model uses a storyline approach, introducing phenomena that anchors storylines developing disciplinary core ideas, concepts, and science/engineering practices. Students are encouraged to dive deep into key points and solve problems through five activities. Students kick off a unit of study, investigate questions, piece together the puzzle in investigations, and problematize the next set of questions to investigate. 

Unit 8.3: How can a magnet move another object without touching it?

This unit launches with a slow-motion video of a speaker as it plays music. In the previous unit, students developed a model of sound. This unit allows students to investigate the cause of a speaker’s vibration in addition to the effect.

Students dissect speakers to explore the inner workings, and engineer homemade cup speakers to manipulate the parts of the speaker. They identify that most speakers have the same parts–a magnet, a coil of wire, and a membrane. Students investigate each of these parts to figure out how they work together in the speaker system. Along the way, students manipulate the components (e.g. changing the strength of the magnet, number of coils, direction of current) to see how this technology can be modified and applied to a variety of contexts, like MagLev trains, junkyard magnets, and electric motors.

Perfectly aligned with each unit, the consumable student workbook provides students with a dedicated space to write through their ideas and thoughts with every exercise and activity helping to reinforce important themes and concepts.

The Student Edition, Teacher Edition and material kits are sold separately.
