This is a series of 10 question recall tests for use at the start or end of a lesson. This presentation includes quizzes on enzymes, enzymes action, enzymes in action and transporting substances. At the end of each quiz is a slide with just the questions on so that they can be printed off and handed out to students as a starter whilst you do the register. The presentation then goes through each questions with the answer so that students can self assess. Alternatively it can be done as a plenary and you can rapid fire targeted questions just using the presentation.
