Lesson Plan : Electricity - Introduction

 Teacher Name: Rachel Hiatt Grade: Grade 7-8 Subject: Science

 Topic: Electricity Content: What is electricity? How does it work? How does it apply to life?/What are its uses and applications? Goals: Students will gain a better understanding of what electricity is based on their current (no pun intended) and previous experience with electricity. Students understand that moving charges transfer electricity. Objectives: Assimilate previous knowledge about electricity with what will be learned. Describe how charged particles behave. Determine how electrons cause charges to build up. Explain how static electricity is used in technology. Materials: SQ3R template - possibly set up on power point/overhead to help students independently take notes. Newspaper plastic bags lab materials for making a static detector - metal paper clip, clear plastic cup with hole, modeling clay, ball of foil, 2 strips of foil, inflated balloons Computer lab - Rose-Prism.org - BrainPOP Electricity Power point notes - (possibly) Introduction: Students will enter classroom with virtually no electricity (lights and computers off)Pose question - what electricity is off and how does it make life difficult? What electricity is still on? Turn on lights and discuss. (5-10 minutes) Development: For 5-10 minutes -have students write down everything they currently know about electricity. Break into groups and look for similarities, and categories that everyone's information can be grouped into -- ask for suggestions from class for categories before giving hints. Some may be: uses, how it works, what it is, etc... Inform students that they will begin with the basics of how electricity works--going back to charges on atoms. (5-10 minutes) Demonstrate with tape on a student. Practice: Students will complete lab investigation involving newspaper and paper bag and then draw conclusion about how materials can become charged based on lab. (10-15 minutes) Students will complete SQ3R notes for Section 1-1 in text using outline. Accommodations: Students will be able to work with a partner to complete SQ3R notes. Teacher will be available to monitor and "walk-through" lab investigations with students. Students are offered "hands-on experience" as well as experience enhancing independent study skills while having an outline to follow. Checking For Understanding: Lab Rubric Quiz over material Observation Homework Closure: Ask students to look back at electricity web created at the beginning of the unit and write a brief paragraph about how what they learned assimilated into the web. Evaluation: Rubric on labs - was there an understanding of the concepts presented based on the students observations and analysis? Quizzes - was there an understanding of the concepts presented based on a "C" average or better on assignments for this section. Could students effectively assimilate what they learned with what they already knew? Teacher Reflections: May have to adjust based on time constraints for student performance evaluation.
