Current Electricity - Ohms Law Distance Learning for Middle School Science

This action-packed animated distance or home learning package starts by demonstrating how metal ions cause resistance in a conductor  and the relationship between resistance and current. Students are then shown how to use Ohms Law to find resistance and are supported towards competence in its use with many worked examples.

This resource has been designed so that the animated PowerPoint replaces the teacher by providing structure, sequence, knowledge and answers. The worksheets, cut-outs, foldable and progress check provide a familiar medium for students to develop and test their knowledge, continue to develop their literacy skills and use their creativity to organise their learning and assess their progress.

Objective

To know that:

• current is a flow of electrons;
• metal ions cause resistance in a conductor;
• electrons collide with the metal ions and loose energy which is converted to heat or light.
• the more metal ions the higher the resistance;
• collisions with metal ions reduce current;
• the higher the resistance the lower the current.;
• the comparative resistance of long/short and thick/thin wires
• R = V/ I

 Be able to:

• apply ohms law in simple calculations;
• apply ohms law in calculations having deduced the values for V and I using prior knowledge of series and parallel circuits;
• explain the use of materials in devices according to their resistance.

Resources

1.     An animated PowerPoint which  guides the student through the lesson by:

• explaining how to use distance learning effectively;
• explaining how to use this resource;
• explaining current, voltage and resistance and the relationship between them;
• providing the answers to all the worksheets so that the students can mark and correct their work. 

2.     Four worksheets, and two  cut-out activities, the answers to which are in the PowerPoint.

3.     A foldable and cut-out activity so that students can record and organise their learning.

4.     A checklist for students to use to assess their progress.

5.     For those students without internet or a computer or a computer at home a condensed printable copy of the PowerPoint is provided for distribution by school.

Ways to Use this Resource

• Upload PowerPoint and worksheets to school intranet. Students print their own worksheets.
• Upload PowerPoint and worksheets to school intranet and provide a hardcopy of worksheets for students. Those families who do not wish to collect worksheets or who are in isolation can print the worksheets at home.
• Students without photocopying facilities are instructed to write their answers in full sentences and to writs a sentence to describe any circuit diagrams drawn.
