These resources are perfect for an introductory lesson on the organisation of multicellular organisms. At the start of the lesson, students are provided with a printed out version of the worksheet. As a starter activity, students label the human body with as many organs as they can. To stretch the top students, I ask them to describe the structure and function of any organs they have named. The PowerPoint resources can be used as a visual stimulus throughout the lesson, to guide students on which activity they should be focusing on. The PowerPoint also includes the answers to the activities on the worksheet. Included within this resource is also a research task which works well as a homework activity.

This lesson guides students through the body’s three main lines of defence again disease. Students begin by considering and discussing what the immune system is and why it is useful. Students then look at the difference between physical and chemical barriers to infection before learning about the process of phagocytosis. Students are introduced the B and T cells, before creating an artistic piece about a pathogen trying to avoid each of the body’s defences.

This lesson introduces students to the science of taxonomy and encourages them to consider why and how we classify living things. The resource includes a fun practical activity that invites students to classify a selection of food items into groups, based on their similarities and differences. Depending on how much time you have available, I then challenge my students to work in groups of five to complete the five kingdoms comparison table on their worksheet. If they finish early, or as a homework activity, I then invite my students to make a set of five top trump cards, one for each of the kingdoms.

The objective of this lesson is to help students understand what is meant by the term ‘balanced diet’ and how energy requirements vary with activity levels, age and pregnancy. This lesson builds upon prior knowledge that a balanced diet should include appropriate proportions of carbohydrate, protein, lipid, vitamins, minerals, water and dietary fibre. Students begin by critiquing BMI as a indication of healthy body mass before considering how and why energy requirements vary from person to person. The lesson encourages students to consider what happens if they don’t get the right amount of the right nutrients, and includes a possible homework activity, to design a TV advert on behalf of the government to encourage young people to eat a balanced diet.

These resources are designed to help students understand the stages of protein synthesis including transcription and translation, including the role of mRNA, ribosomes, tRNA, codons and anticodons. The PowerPoint includes a series of useful links to youtube videos on the topic, as well as a past paper question and mark scheme.

This resource is ideal for a first lesson on the topic of disease. The first slide includes a series of questions for students to discuss about diseases. The second slide introduces the six different types of pathogens. Students can then copy and complete the table on the third slide, about the structure and modes of reproduction, using the remaining slides on the powerpoint, their textbooks and/or the internet. The fill-in-the-blanks worksheet can be used alongside the powerpoint resource and includes examples of diseases caused by bacteria, virus’s and fungi.

The key objective behind this scheme of work is to enable students to draw, interpret and use graphs of motion to analyse the motion of objects. The learning outcomes include: Speed, distance and time Distinguish between (i) distance and displacement and (ii) speed and velocity 2, Give the SI units for distance, displacement, speed and velocity. Define (average) speed as: speed = distance travelled / time taken Solve problems using this equation using correct units. Recognise that (instantaneous) velocity of an object is its (instantaneous) speed in a stated direction. Draw and interpret distance vs time graphs: relating the speed of an object to the gradient of the line (for objects moving quickly, slowly, speeding up, slowing down or stationary) find the speed by calculating the gradient of the graph recognise a negative gradient as motion backwards Acceleration Define acceleration Solve problems for accelerating objects speeding up or slowing down using the equation for acceleration and correct units. Draw and interpret velocity vs time graphs: Relating the gradient of the line to the acceleration of the object Calculating the acceleration from the gradient Relate the acceleration of an object to the application of a (net) force

The key objective behind this scheme of work is to enable students to describe, in words and using mathematics, the essential features of sound and light waves and their propagation. The learning outcomes are detailed below: Features of Waves Describe a progressive wave. Distinguish between transverse and longitudinal waves (with reference to the direction of oscillation of the particles). Give examples of transverse and longitudinal waves. Define the following terms and identify them on diagrams (for transverse waves only): wavelength, amplitude, particle displacement Define the period and frequency of a wave, finding one given the other. Use the wave equation to explore the relationship between the speed of a wave, frequency and wavelength: v=fλ Sound waves Interpret traces of sound waves (made by a CRO, for example) Relate the properties of a sound wave to the pitch, volume and timbre of a sound. Outline and evaluate an experiment to measure the speed of sound in air. Electromagnetic Waves Distinguish between mechanical waves and electromagnetic waves. Outline differences and similarities between sound and light waves. List the components of the electromagnetic spectrum in order of frequency and wavelength. Identify the components of the electromagnetic spectrum that are ionising and discuss their dangers. Give uses for each component of the electromagnetic spectrum (including the use of electromagnetic waves for communication and for medical imaging). Identify that when a wave strikes a surface or change in medium, there will be reflection, transmission and absorption.
