Electricity Guide
This Electricity Teacher’s Guide is designed to coordinate with the ScienceWiz™ Electricity Teacher’s Pack which includes a book and materials for each student in the class, as well as the ScienceWiz™ Electricity Workbook, which is sold separately.
Student Online Courseware Materials are also available.
Student interactive materials and assessments are provided in two forms:
1) One set of materials is for group sharing and for discussions at the front of the class. You can present these materials using this guide. This Teacher’s Guide includes a highlighting capability which converts the selected text into speech. Highlight text to speak. Double click outside the text anywhere on the window background to stop the speech-to-text feature.
2) The second set of materials is available for each individual student as courseware. The instructor will need to enter or bulk load the students’ names and email (or parents’) accounts to make use of this online courseware component. The online student courseware offers auto-grading and auto-record keeping.
Each student account also includes:
- a highlighting capability which converts the selected text into speech.
- an individual note-taking capability.
Your feedback is greatly appreciated. Please let us know what you like and what you would like to see changed or improved (pan@sciencewiz.com).
Module 1: Electricity
This introduction to electricity explores simple circuits within the context of circuit loops. The first module presents the topic of Electricity to early elementary students. This module consists of six separate 30 – 40 minute lessons. Animations, videos and online simulations are provided.
To prepare for this science module, read and study the book, pages 1-33.
Module 1 – Lesson 1: Electrical Current Flows in a Loop (pgs 1-6)
Learn about the idea of a “loop” in terms of potholder loops. Then extend that understanding to electrical circuit loops.
Bring to class: D-cell batteries — 1 per student.
Hand out a red potholder loop and an Electricity Book to each student.
Use the slide show feature to project each page on the large classroom screen.
Students will follow along using their own readers.
SLIDE SHOW DIRECTIONS:
- Below is a single slide.
- Click on the image to launch the slide show.
- Use the side arrows to go to the next or previous slide when there are multiple slides.
- Use the X at the top right corner to end the slide show.
Read aloud page one.
Have each student shape their loop into a square, a triangle, a circle and an oval.
Emphasize: No matter what shape it is — IT IS STILL A LOOP.
Read aloud page two.
Write LOOP on the board.
Ask students to write it forward and backward.
What does it spell when they write it backward?
Read aloud page three.
Have students trace the electrical circuit loop with their fingers.
Hand out the battery bands, the alligator leads and the bulb holders.
Read aloud page 4-5.
Following the instructions, have each student build their own circuit loop to light the bulb.
