This is an animated PowerPoint presentation that covers the Nervous System part of Section 2.4 Coordination of the Edexcel IGCSE Biology course.
The PowerPoint covers the following questions:
How and why do organisms respond to changes in their environment? Can you list what is required for a coordinated response? What makes up the CNS? Can you explain that receptors are used to generate impulses in neurones, resulting in a rapid response? What is a reflex arc?
The PowerPoint is designed to directly address each relevant point in the syllabus. It is simple and straight to the point covering the topic in just the right amount of detail.
It is a fantastic resource for both teachers and students or a great tool for revision.
Many of the slides have animations in that will only work when viewed in slideshow mode, so please use that when working through the presentation.
