Units offer as guides to a specific content or topic area. Nested under units space lessons (in purple) and hands-on activities (in blue).

keep in mind that not all lessons and tasks will exist under a unit, and instead may exist together "standalone" curriculum.

an overview

Student groups investigate the properties of electromagnets. They develop their own small electromagnets and experiment with ways to readjust their toughness to pick up more paperclips. Students learn around ways that designers use electromagnets in everyday applications. This design curriculum set to next Generation scientific research Standards (NGSS).

Figure 1. A simple electromagnet.

Engineering link

Engineers design electromagnets, which room a basic part of motors. Electromagnetic electric motors are a big part of daily life, as well as industries and also factories. We may not also realize the we connect with electromagnets top top a everyday basis as we usage a wide range of motors to make our resides easier. Usual devices that use electromagnetic motors are: refrigerators, apparel dryers, washing machines, dishwashers, vacuum cleaners, sewing machines, garbage disposals, doorbells, computers, computer system printers, clocks, fans, car starters, windshield wiper motors, electrical toothbrushes, electrical razors, can openers, speakers, music or ice players, etc.

finding out Objectives

After this activity, students should be able to:

Relate that electric existing creates a magnetic field.Describe just how an electromagnet is made.Investigate methods to change the strength of one electromagnet.List number of items that engineers have designed making use of electromagnets.

Educational criter

every betterworld2016.org great or activity is associated to one or an ext K-12 science, technology, engineering or math (STEM) education standards.

all 100,000+ K-12 STEM standards covered in betterworld2016.org are collected, maintained and also packaged through the Achievement criter Network (ASN), a project of D2L (www.achievementstandards.org).

In the ASN, standards space hierarchically structured: first by source; e.g., through state; within source by type; e.g., science or mathematics; within kind by subtype, then by grade, etc.
