Intro to Current Electricity 4 - Classroom, Distance and Blended Learning for KS3

For each of the two topics listed below, the same lesson to be taught to students whether they are in a classroom or distance learning at home.

• Switches in Series and Parallel Circuits
• Ohms Law

They facilitate hybrid learning and provide equality of opportunity for students who are unable to attend school.

Objectives

To know:

• that switches open and close circuits.
• that one switch controls all the components in a series circuit.
• that components can be controlled individually by switches in a parallel circuit.
• how to position switches correctly in simple and complex parallel circuits.

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.

The classroom resources consist of an animated 11 and 24 slide PowerPoint and 11 and 13 varied and exciting printables including a foldable, cut-and-stick and progress check. Each topic comes with a one-page flowchart lesson plan shows where choices can be made between the printables so that the teacher can select the activities to suit the exact needs of their class.

The distance learning resources consists of a 32 and 45 slide animated PowerPoint which, not only teach the science but also how to gain maximum benefit from distance learning. The PowerPoint shas been designed to replace the teacher by providing structure, sequence, knowledge and answers. Additional 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. These can be printed off by the student or provided by school. There is also a short digital test/homework which can be returned to the teacher.
