Biological molecules is often a topic that students struggle with in A-Level Biology. This resource provides a table in which students can pull together all their notes on the different categories of molecules, including carbohydrates, fats and proteins. Nucleic acids are also included as extension and to foster links between different units.

A method sheet that discusses how to extract your own DNA from cheek cells. Highly engaging and suitable as a starter activity for any biology topic involving nucleic acids. Much more interesting than the usual extraction of DNA from Kiwi fruit or onions!

This activity sheet is suitable for A-Level Biology and BTEC Level 3 Science students; it is part of my DRAW IT series and contains a list of descriptions that detail how competitive and non-competitive inhibitors work. Students are tasked with reading each description carefully and then illustrating each description; meanwhile, other students in the class can be given the textbook style diagrams and are asked to provide a written commentary. After both sets of students have finished, they can then be paired up and tasked with comparing their written notes/ illustrations and explain the process to each other. Finally, the lesson can be concluded by asking students to verbally describe each step in the process during a question and answer plenary. I first devised DRAW IT tasks as a way of turning fairly dry subject material into something more interactive and student led. DRAW IT tasks can easily change a teacher led session into a much more engaging, enjoyable and competitive classroom activity.
