DNA Structure

This PowerPoint resource provides a useful visual aid for a lesson on the discovery and structure of DNA. It includes activities, questions and video links. I usually begin the lesson by inviting students to write down everything they already know about DNA in a black pen. I then introduce Watson and Crick, and the structure of DNA, using all the key terms on the slide. I then give my students minutes to answer the 6 mark question on the structure of DNA. Students then self-mark their answer using the mark scheme included in the PowerPoint, and show me on their fingers how many marks out of 6 they achieved for the question. If students have access to their own laptops I then invite students to watch a few of the video links that go into slightly greater detail about the structure of DNA. At the end of the lesson I ask the students to return to the list they made at the beginning of the lesson about everything they already knew about DNA. I invite the students to spend a couple of minutes adding to their list in a green pen with everything they now know about DNA.
