This easy to use resource provides a useful visual aid and series of activities to help students understand the levels of organisation in multicellular organisms.

This creative resource introduces the structure and function of the lungs. It includes useful activities that are engaging for students and helps them master the topic.

This resources provides a useful and easy to use visual aid for introducing human taxonomy, the features that we share with our closest living relatives and the features that make us unique. It introduces a couple of the key hominid fossils that have enabled scientists to understand more about our evolution and includes links to a great online resource on the topic.

This resources provides a useful and easy to use visual aid for a big questions in evolution lesson. It includes two graphs for students to interpret, links to videos, and questions to initiate discussion and research on the topic.

This resource provides an easy to use visual aid for a lesson introducing muscles, joints and antagonistic muscles.

This PowerPoint resource provides is fun and easy-to-use. It includes a series of show and simple activities that introduce students to food chains, what they are and what they represent. It covers several key terms for the topic, including: producer, consumer, herbivore, omnivore and carnivore. This resource also covers disruptions to food chains and why food webs provide a more accurate representation of a natural ecosystem than food chains do.

This resource introduces electron microscopy, compares light and electron microscopy and considers the advantages and disadvantages of light and electron microscopy.

This resources provides a fun and colourful introduction to enzymes. It is both a useful visual aid and includes past paper questions for students to answer. The resource defines enzymes as biological catalysts, made of protein, and breaks this definition down so that it is easy to understand. It introduces the lock and key theory as well as denaturation.

This resource considers four factors that effect the rate of an enzyme-catalysed reaction: temperature, pH, concentration of enzyme, and concentration of substrate. This resource includes enough information and visual aids to fill 2 or 3 lessons. When I teach this topic, my students carry out a simple experiment, looking at the rate of hydrogen peroxide decomposition, to provide experimental evidence for the effect of pH and temperature on enzyme (catalase) activity.

This resource introduces the different food groups, how and why they are broken down, and the tests used by scientists to find out which food groups different products contain.
