Netlogo Investigations In Electromagnetism (Niels)

Subject: Physics
Time: 2 weeks
Level:

High School


Unit Overview

Students will explore Coulomb's Law and connections between Kinematics and Electrostatics Motion. Students will learn that oppositely charged particles attract each other and particles with the same charge repel each other. Students will discover that Coulomb’s force between a pair of particles is determined by the distance between the particles and the charge of each particle.

Students will learn about electric field lines and motion of electrons in an electric field. Students can also reflect about the relationship between force and motion • Students will directly confront a very common misconception: electric field lines also represent trajectories of charges. They will develop an understanding of why that is not necessarily the case, and learn to differentiate between field lines and paths of charges.

Students will learn that electric current depends on length, and width of the wire, as well as the applied voltage. Additionally, students will learn to develop measures for measuring electric current.

Lessons Overview

1. Lesson 1 - Electrostatic Motion Overview

In this lesson, students will explore Coulomb's Law and connections between Kinematics and Electrostatics Motion. Students will use computational models built in a modeling environment called NetLogo to explore how charged particles interact.

2. Lesson 2 - Lines of Force Overview

In this lesson, students will continue their investigation of the motion of electrons due to electric forces.They will explore the notion of electric field lines, which are visualizations of electric field. Students should investigate "what do the field lines represent?" They should be introduced to how to generate a continuous field by "spatially arranging" poles. 

3. Lesson 3 - Measuring Current: Wire Width Overview

Throughout lessons 3, 4, and 5, students will continue to deepen their understanding of how to measure electric current, and how constancy of flow is maintained. Students will develop two different ways to measure current: average current and instantaneous current. Students will be introduced to some computer-based modeling to achieve this. 

In this lesson particularly, students will identify how electric current depends on the width of the wire, as well as the applied voltage. They will also start to explore tools for measuring electric current (sampling different areas of the wire, and comparing the values; averaging) and aggregate data they collect with the class. 

4. Lesson 4 - Measuring Current: Wire Length and Metal Type Overview

In this lesson students will explore how electric current flows in a wire and explore how current depends on applied voltage, wire length, and wire material. Additionally, students will continue to explore ways to measure current and find ways to aggregate their own data using computational tools. They will be introduced to an additional modeling tool called Codap which allows data from NetLogo to be displayed in a table and be manipulate and analyzed. 

5. Lesson 5 - Measuring Current: Instantaneous and Average Overview

Students will further develop their understanding of the two different ways to measure current: average current and instantaneous current. Students will be introduced to some computer-based modeling to achieve this, and will interact directly with the NetLogo code and be prompted to write their own code as well.
