Breathing and the Respiratory System Explained - Distance Learning and Homeschool - KS3

This is an action-packed distance learning or home school introduction to breathing and the respiratory system.

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.

The simulated practical takes the student through designing an investigation, a table and drawing a graph.
