IGCSE Plant Reproduction

IGCSE Plant Reproduction

A power point which introduces the structure and function of the parts of a flower. Students then analyse the differences between the insect and wind pollinated flowers. There is a brief explanation of fertilisation and formation of the pollen tube. Finally looking at asexual and sexual reproduction in plants. The power point contains the whole lesson and it is easy for the teacher to follow the plan of the lesson with tasks for students clearly highlighted and check points to ensure learning. I have used a ppt slide from the author clickbiology as I think it is one of the best slides on flower structure I have seen.

IGCSE Properties of Covalent bonding

IGCSE Properties of Covalent bonding

A whole lesson in a power point presentation which looks at the properties of covalent bonds to include, why substances with a simple molecular structures have low melting and boiling points and how these increase with increasing relative molecular mass; why substances with giant covalent structures have high melting and boiling points and how the structures of diamond, graphite and C60 fullerene influence their physical properties, including electrical conductivity and hardness. There is plenty of opportunity for students to research and analyse data on certain covalent substances to build up a picture of covalent properties. There is also an exam question with mark scheme.

GCSE - Introduction to the Eye + Dissection

GCSE - Introduction to the Eye + Dissection

A whole lesson plan allowing students to discover the structure and function of the eye. This lesson is following the double award IGCSE for Edexcel and students need to describe the structure and function of the eye. I have not included information about accommodation. This lesson is a lovely introduction to the eye and includes an eye dissection task plus a 3D image starter activity; exam question and brief investigation into the response to bright light.

(I)GCSE Plant Transport - structure and function of xylem and phloem

(I)GCSE Plant Transport - structure and function of xylem and phloem

A PPT which introduces the role of both xylem and phloem. The first activity is a research activity (8 minutes) where students use resources available to determine characteristics and roles of phloem and xylem. The next 20 minutes is a circus of activities with microscope work (drawing xylem and phloem); observing dye in celery; dendrochronology (tree rings) and transpiration and translocation.

(I)GCSE Photosynthesis Formative Assessment Task

(I)GCSE Photosynthesis Formative Assessment Task

A formative assessment task which can take 2 lessons or be set as a homework. I set this before the end of topic test to allow students time to clarify the ideas behind the unit. Students can use their text books and tablets but the work must be explained in their own words. I have included the criteria to include in the poster and the mark scheme which would be used to grade the work. This works well as a peer assessment as well as a teacher assessed task.

(I)GCSE Photosynthesis Introduction

(I)GCSE Photosynthesis Introduction

A power point full lesson allowing students to understand the role of photosynthesis in producing glucose for energy storage. Student should be able to understand the process of photosynthesis and its importance in the conversion of light energy to chemical energy Write a word and balanced symbol equation for photosynthesis Describe adaptations of a leaf for efficient photosynthesis There is a six mark exam question and mark scheme for self/peer assessment.

A2: Controlling the Breathing Rate. The role of the respiratory centre.

A2: Controlling the Breathing Rate. The role of the respiratory centre.

A complete lesson to introduce the idea of how exercise can increase the rate of ventilation to remove the build up of carbon dioxide. It looks at the negative feedback systems involved which maintain breathing rate. It also introduces spirometer traces and the definitions which which will lead to the core practical (edexcel IAL). There are plenty of discussion opportunities, a video and an exam question for self assessment.

A2 Controlling the Heart Rate - cardiovascular control centre

A2 Controlling the Heart Rate - cardiovascular control centre

A lesson which explores the effect of exercise and heart rate on the body. Students learn how to calculate cardiac output. The power point explores the role of the cardiovascular control centre. Students complete a diagram showing how both the sympathetic and parasympathetic nervous systems can increase/decrease the heart rate depending on blood pressure, need for oxygen and glucose. There is a little practical activity when students observe the effect of adrenaline on heart rate and how quickly heart rate changes.

IGCSE Covalent Bonding

IGCSE Covalent Bonding

A lesson to introduce the concept of covalent bonds through PPT and animation. Students learn the rules of how to draw dot cross diagrams to represent covalent bonds and apply their knowledge to draw hydrogen chloride, chlorine, oxygen, ammonia, methane, ethane, ethene, water and carbon dioxide.

A Level: Homeostasis and Negative Feedback Loops

A Level: Homeostasis and Negative Feedback Loops

This lesson is an introduction to homeostasis and feedback loops. I have designed this lesson as a transition between GCSE and A level content. Students define the terms homeostasis and negative feedback. I have then used the examples of water and glucose regulation to allow students to work through the process. I have included a copy of the BBC short circuit video about Leah Betts as this highlights the issues associated with ecstacy and the failure of water regulation in the body. Next lesson we will focus on the control of heart and breathing rate and link this to exercise.

Edexcel IAL: The Relative effect of Genotype and the Environment

Edexcel IAL: The Relative effect of Genotype and the Environment

This PPT introduces the idea that it is difficult to assess the relative contribution of both genes and the environment to disease. It introduces some examples of how genes and the environment interact e.g. siamese cat colour; oncogenes. This lesson is for promoting class discussion rather than many individual activities. I have included an exam question and mark scheme in the PPT This is an A level lesson but would be suitable for a high ability GCSE to promote discussion.

I/GCSE Reflex Arc Whole Lesson

I/GCSE Reflex Arc Whole Lesson

A complete lesson with worksheets and exam questions/answers which introduces the reflex arc. There are simple animations which show the route of the impulse. Synapses are not covered in detail as they are not needed for double award syllabus (edexcel IGCSE).

Surface Area to Volume Ratio in Organisms

A PPT with complete lesson with different activities to introduce the idea of surface area and volume and how it is affected by the size of an organism. Activities include - calculating the surface area and volume of 3 cubes; explaining why certain cells/organs have a large surface area. There is also an edexcel IGCSE exam question and mark scheme for self assessment.

Edexcel Scientific Article January 2018 - Chasing the Cure: Parkinson´s disease

This will help your students prepare for the Unit 5 exam this January 2018. I have provided a sheet of key vocabulary - very useful for IAL students. I have also provided exam style questions which cover areas in the article students may be questioned on. I have provided an answer sheet. *I have attached a copy of the Edexcel article - Chasing the Cure: A decade of Parkinson´s disease. This is not a resource I have prepared, just downloaded from the edexcel website*

A2 Biology Muscle Contraction

A2 Biology Muscle Contraction

This is a 2 part lesson for muscle contraction. It introduces actin-myosin interactions in the sliding filament theory. I have included some PPT slides from boardworks which highlight this interaction very well. I have also included 2 videos from youtube which I find very helpful. The crash course video can be used in either lesson 1 or 2. The Biology ATP Myosin video is a resource I use along slide the boardworks presentation on muscle contraction where students use both resources and their books to produce a flow chart or bullet points explain what occurs in the sarcomere. There is also an exam question at the end of lesson 2. *please note that you will need to enable macros on PPT to allow boardworks to be interactive
