This resource introduces the phrases of the moon and how solar and lunar eclipses form. It is an incredibly useful visual aid and includes a series of questions about eclipses for students to respond to.

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 introduces reactions between metals and water and the reactivity series.

This resource introduces reactions between metal and acids, word and symbol equations, as well as the squeeky pop test.

This resource introduces circuit symbols and scientific diagrams of electrical circuits. It includes a series of short activities to test student knowledge and understanding of the topic.

This PowerPoint provides a useful visual aid for a lesson on series and parallel circuits. Before the lesson starts, I set up four electrical circuits in the classroom (these are shown on slide 3). Students begin by recapping how they draw electrical diagrams before being introduced to the idea of series and parallel circuits. Students then perform a series of very simple experiments to help them compare current and voltage in series and parallel. After completing the experiments and feeding back their findings to the class, the students complete two fun and easy assessment for learning activities. One is a back-to-back diagram drawing activity and the final activity uses dice and encourages students to reflect on what they have learned.

This resource introduces moments as the turning effect of a force, the equation for calculating moments, and the law of moments. It includes several questions for students to complete, to help ensure a secure understanding of the knowledge.

This resource introduces synthetic and natural polymers, it challenges students to interpret data about different polymers, use information to decide which jobs different polymers could be used for, plot a graph based on scientific data, and research different types of polymers.

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 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.

This resource introduces circulatory systems, compares circulatory systems in different vertebrate classes (fish, amphibians and mammals), compares veins arteries and capillaries, and also looks at the impact of fatty deposits on blood pressure. It includes a range of activities and questions for students to answer on the topic.

This resource introduces photosynthesis, the work and symbol equation for photosynthesis, what happens to the glucose produced in photosynthesis and compares photosynthesis and respiration. The lesson concludes with three short answer past paper questions on photosynthesis.

This resource covers the control of blood sugar and what happens if you are unable to produce enough insulin. It includes useful links to animations on blood glucose control and questions for students to answer.

This resource helps students draw conclusions about the number of electrons and electron shells in atoms as you go down groups and across periods of the periodic table.

This resource, provides an easy to use, simple visual for an introductory lesson on mitosis and the cell cycle. The resources includes a couple of useful links to videos as well as a true false quiz on the topic.

This resource begins by introducing stem cells and their uses, before inviting students to write a clearly balanced account of the arguments surrounding the use of stem cells in research. It then moves on to introduce designer babies and encourages students to write a clearly balanced account of the arguments surrounding designer babies. This lesson provides excellent opportunities for class discussions on ethically challenging topics and an opportunity for students to complete extended pieces of writing. The resource includes links to useful videos on the topic.

This resource provides useful images and links to videos to help stimulate discussion on genetic modification and CRISPR. It also includes a list of questions for students to answer on the topic of genetic engineering and biotechnology.
