This lesson describes how the movement of growth factors regulates growth in response to directional stimuli, focusing on gravitropism and phototropism. The PowerPoint and accompanying resources are part of the 1st lesson in a series of 3, which have been designed to cover point 6.1.1 (Survival and response) of the AQA A-level biology specification. The lesson begins with a prior knowledge check, where the students have to identify key terms encountered in topics 1 - 4, and use their 1st letters to form the term, stimuli. Students are reminded of the meaning of a stimulus, and this introduces the need for organisms to detect and respond to stimuli, to increase their chances of survival. This lesson focuses on these responses in flowering plants, and builds on any knowledge they may have gained at GCSE. They should have met auxins at this previous level, but will now be introduced to IAA, and will complete several tasks which check that they understand the key features of these chemicals, such as their location of production and method by which they move through the shoots and roots. The students are guided through the movement of IAA to the shaded side in a shoot during phototropism, and will learn how this uneven distribution leads to uneven growth. An exam-style question presents them with two further scenarios, where the tip of the shoot has been cut off or is covered, and the students need to describe and explain what will happen to the appearance of the shoot after a week. Moving forwards, the students will learn how the pumping of hydrogen ions into the cell wall and the activation of expansin proteins are involved in the cell elongation. The remainder of the lesson discusses the response to gravity and explains how shoots and roots respond differently. The lesson is full of understanding and prior knowledge checks and all answers are embedded into the PowerPoint. The other two lessons in this series of 3 covering 6.1.1 describe taxes and kineses and the protective effect of a simple reflex.

This lesson has been designed for GCSE students (14 - 16 year olds in the UK)

A detailed lesson presentation which guides students through calculating the current, potential difference and resistance in series and parallel circuits. The lesson begins by challenging the students to recognise whether three displayed facts relate to series or parallel circuits. Students are then given a chance to remind themselves of the differences between the circuits in terms of these three physical factors. The rest of the lesson uses a step-by-step guide format to show the students how to work through a circuit calculation by combining their knowledge of the circuit with application of the V = IR equation. Progress checks have been written throughout the lesson so that students can constantly assess their understanding. This lesson has been designed for GCSE students

An engaging lesson presentation and associated worksheet that looks at the use of antibiotics to treat bacterial infections and the raises the issue of the potential over-use of these substances. The lesson begins by getting the students to recognise the difference between three key terms that begin with anti (antibiotics, antivirals, antiseptics). Students will be introduced to the idea that antibiotics are specific to a small range of bacteria and therefore the correct one has to be selected before being prescribed. Moving forwards, students will meet the idea of the zone of inhibition and will understand how the size of this zone can be used as an indicator to the effectiveness of the treatment. Students are shown how to calculate the size of the zone and then are tested on their ability to apply this mathemetical knowledge. Finally, time is taken to look at the links to the topic of natural selection to explain how some bacteria are resistant to certain antibiotics. There are regular progress checks throughout the lesson so that students can assess their understanding. This lesson has been designed for GCSE students but could be used as an introduction with A-level Biology students who are about to begin the topic of immunity.

A resourced lesson which looks at the chemical reaction that is aerobic respiration and ensures that students can apply their knowledge to application questions which challenge them to make links to related topics. The lesson includes an engaging lesson presentation (27 slides) and an associated worksheet containing questions. The lesson begins by challenging the students to recognise a definition for breathing and a definition for respiration. This is aimed at helping them to understand that these are different processes as this is a common misconception made by students. Moving forwards, key details about aerobic respiration are introduced to the students through a range of tasks which include competitions to maintain engagement. Time is taken to ensure that students become familiar with ATP and understand that this is the energy store which will be broken down to release energy for the activities that occur in a living organism. The remainder of the lesson challenges the students to take their new found knowledge of aerobic respiration and apply it to range of unfamiliar situations such as explaining why a root hair cell would have such a large number of mitochondria. There are regular progress checks throughout the lesson to allow the students to check on their understanding. As always, the lesson finishes with a slide containing advanced terminology so that students who have aspirations to take A-level Biology can extend and deepen their knowledge

A fully- resourced lesson which looks at the chemical reaction that is anaerobic respiration and ensures that students can understand why this form of respiration can only be used for short periods of time. The lesson includes an engaging lesson presentation (39 slides), a newspaper article and application questions. The lesson begins by challenging the students to recall information about aerobic respiration to recognise that the sole reactant of anaerobic respiration is glucose. A newspaper article about two atheletes from the 10000m race has been written to challenge the students to recognise why one of the athletes wouldnt be able to compete again in the near future whilst the other could. As a result, students will be introduced to lactic acid and will learn how this poisonous substance prevents muscle contraction and causes cramps. Time is taken to ensure that students are familiar with ATP and specifically that they recognise that a much lower yield is produced in this type of respiration. A perfect opportunity is taken to get the students to carry out a mathematical calculation to compare the yields. Oxygen debt is discussed and related back to the original newspaper article. Finally, anaerobic respiration in plants and yeast is considered in terms of fermentation and the word and symbol equation is written so that it can be compared to those from animals. There are regular progress checks throughout the lesson to allow the students to check on their understanding. The lesson has been written for GCSE students but could be used with higher ability KS3 students or A-level students who want a recap before covering the topic in greater detail on their course.

A fully-resourced lesson that looks at the details of the electrical topic of resistance that students need to know for GCSE. The lesson includes a lesson presentation (21 slides) and associated worksheets. The lesson begins by looking at the meaning of resistance and focuses on the connection between resistance and current. Moving forwards, net resistance in series and parallel circuits is introduced and explained.

A resourced lesson which looks at calculating acceleration using the (v-u)/t equation. This lesson includes an engaging lesson presentation (26 slides) and a worksheet of questions that can be used for homework or during the lesson. The lesson begins by looking at the actual meaning of acceleration, ensuring that students understand it is a rate and therefore recognise the units as a result. A number of engaging activities are included in the lesson, such as the ACCELERATION OLYMPICS, to maintain motivation. Students are shown how to rearrange the equation to make velocity or time the subject and then challenged to apply these in a series of questions. Deceleration is briefly mentioned at the end of the lesson. This lesson has been primarily designed for students studying GCSE (14 - 16 year olds in the UK) but it is suitable for students at KS3 too.
