Current Electricity Intro 3 - Homeschool and Distance Learning Three Lessons for KS3

Batteries and Current, Batteries and Voltage and Resistance and Current in Electrical Circuits Explained – these three action-packed distance or remote learning packages for middle school science use animated PowerPoints and a host of engaging worksheets and activities to provide students with a thorough understanding of the concepts.

These resources have 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.

The simulated practicals take the student through planning, designing a table and drawing conclusions from a given set of typical results.

Objective

• To know that an electric current is a flow of electrons which pick up energy from the battery.
• To know that as batteries are added to a circuit current increases and the lamp gets brighter.
• To be able to make a prediction and design an experiment to investigate the relationship between the number of batteries and current.
• To be able to draw a bar graph.
• To be able to calculate the output of n number of batteries from known numbers of batteries, voltages and currents.
• To know that an electric current is a flow of electrons which pick up energy from the battery.
• To know that as batteries are added to a circuit, voltage increases and a lamp gets brighter.
• To be able to make a prediction and design an experiment and results table to investigate the relationship between the number of batteries and voltage.
• To be able to calculate the output of n number of batteries from known numbers of batteries.
• Know that batteries contain chemicals which provide the push or voltage to make current flow.
• Know that electrons collide with metal ions in a conductor and loose the energy they picked up from the battery with each collision.
• Know that resistance increases with the number of metal ions.
• I know that collisions slow down electric current.
• Be able to design an experiment and a results table.
• Draw circuit diagrams from a description.
• Be able to explain the relationship between resistance and current.

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.

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

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

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

4. 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.
