11 ) Plan and carry out investigations to evaluate how various factors (e.g., electric force produced between two charged objects at various positions; magnetic force produced by an electromagnet with varying number of wire turns, varying number or size of dry cells, and varying size of iron core) affect the strength of electric and magnetic forces.

Subject: Science (8)
Title: Building a Better Electromagnet
Description: In this activity, students will construct their own electromagnet from a battery, wire, and a nail. This resource is a result of the ALEX Resource Development Summit.

Title: Build an Electromagnet
URL: http://sciencenetlinks.com/lessons/build-an-electromagnet/
Description: In this lesson, students will make a simple electromagnet by wrapping a wire around a nail and attaching the ends of the wire to a battery to make an electric circuit. As current flows through the coil, a magnetic field is produced and the nail is magnetized. Lessons like this one help to build a foundation upon which students can develop their ideas about gravitational force and how electric currents and magnets can exert a force as well.
