A very good PowerPoint which will help students describe what happens when white light is shone through a prism, as well as be able to explain what happens when white light is shone through a prism, using specialist terminology. There is a worksheet attached for students to complete which pretty much summarises what is covered in the PowerPoint.
A lesson that explains what the heart is, what the four major blood vessels associated with the heart are, how blood flows through the heart (step-by-step) and what valves are and their function. Includes an interesting activity and two exam-style questions so students can apply knowledge learnt.
