Magnification Calculations Homework (GCSE Microscopes)

Magnification Calculations Homework (GCSE Microscopes)

This 11 mark sheet challenges students to convert units from cm or millimetres into micrometres and to use the magnification formula to complete 3 calculations as well as identify the type of electron microscope used to obtain each image. The included mark-scheme is a PowerPoint file allowing easy feedback and peer or self assessment.

Looking at Cells (GCSE) - Microscopes and Magnification Worksheet with Markscheme.

Looking at Cells (GCSE) - Microscopes and Magnification Worksheet with Markscheme.

This double-sided worksheet introduces students to both light microscopes and both forms of electron microscope. It also challenges them to some magnification calculations. Students will learn to differentiate between images from scanning and transmission electron microscopes and also be challenged in converting measurements in centimetres and millimetres into micrometres. The activity serves as an excellent primer for a microscope practical and should follow a demo where a teacher discusses the roles and names of the parts of a microscope. The sheet is accompanied by a full markscheme.

Light Microscope Practical - Onion Cells (GCSE required practical)

Light Microscope Practical - Onion Cells (GCSE required practical)

Aimed at GCSE this task sheet is intended to guide students through their first attempts at using an optical microscope. At the end of the task students will have focused their microscope at different magnifications, made a scientific drawing of the onion cells, measured a cell using an eyepiece graticule and calculated the magnification of their drawing.

Respiration - The Electron Transport Chain (Oxidative Phosphorylation for A-level)

Respiration - The Electron Transport Chain (Oxidative Phosphorylation for A-level)

This double-sided worksheet covers the electron transport chain in detail. The first side is a blank diagram for students to annotate, whilst the second consists of several questions to both test and reinforce understanding. The included PowerPoint serves as a mark-scheme for the sheet but also includes a step-be-step description of the happenings in the electron transport chain and could easily double as a teaching resource.

KS3 Physics Lesson Resources - Light - Refraction (Lessons 4&5)

KS3 Physics Lesson Resources - Light - Refraction (Lessons 4&5)

The resource consists of a 16 slide PowerPoint, a short summary worksheet, and practical task worksheet. The PowerPoint details learning objectives and a starter/stimulus activity for students before diverging into four separate sections which can be navigated from the central menu. The four sections deal with: Explaining Refraction; Ray Diagrams; Lenses; and Refraction in real life. Each section consists of animated slides and diagrams which help explain all the necessary content with a few optional extras for those more capable classes. The summary sheet should serve to help students reflect on and revise the taught concepts and ties in with the PowerPoint. The Practical Worksheet talks students through a series of experiments using rayboxes and prisms/lenses (Specifically rectangular prisms and converse lens prisms - though an extension activity allows for further experimentation) and has an open-ended extension activity for more able students.

A level Biology - Active Transport: The Sodium-Potassium Pump

A level Biology - Active Transport: The Sodium-Potassium Pump

This PowerPoint is a step-by-step, annotated accounting of the working of the sodium potassium pump. Simple animations show the interactions of pump, ATP, ADP, sodium ions and potassium ions. Also included is a scaffolded notesheet including part-drawn diagrams that students can quickly complete as they learn about the process. Please note: The preview thumbnails have unfortunately created some graphical glitches/artefacts that don't appear in the actual slides.

Photosynthesis/Respiration Card Sort & Summary Sheet

Photosynthesis/Respiration Card Sort & Summary Sheet

The card sort resource can be printed off onto card and cut out either before or during lesson time. It can be used as a simple starter/summary activity and is useful to tease out students' understanding of both photosynthesis and respiration and to highlight the relationship between the two processes - that is that one is locking energy into a glucose molecule, whilst the other releases it for use. The one sided worksheet included serves to record students findings and encourages them to reflect on the task. A mark-scheme is also included.

GCSE - Inheritance & Family Trees - Polydactyly

GCSE - Inheritance & Family Trees - Polydactyly

This sheet and PowerPoint introduce family trees and reinforces work on monohybrid inheritance and punnet squares. The sheet includes interpretation and completion of a family tree alongside some punnet squares and reasoning questions. The Powerpoint of only 4 slides acts as an initial stimulus but also shows the solution to the family tree.

KS3 Physics Lesson Resources - Light - Reflection Practical (Lesson 3)

KS3 Physics Lesson Resources - Light - Reflection Practical (Lesson 3)

2 Resources Included: 1.) Reflection practical worksheet - looking at specular and diffuse reflection. A more open-ended extension activity for more able students forms the final task and allows further experimentation - with curved mirrors for example. 2.) A consolidation or homework task that puts the emphasis on the correct drawing of ray diagrams.

KS3 Physics Lesson Resources - Light - The Human Eye (Lesson 6)

KS3 Physics Lesson Resources - Light - The Human Eye (Lesson 6)

The lesson could be a single period or part 1 of a double linking eye structure to that of a camera. The PowerPoint of 16 slides outlines the structure of the human eye and it's functioning. Optional slides allow further exploration of its various structures for more able groups. Where appropriate, diagrams are interactive or animated to aid explanation or even facilitate greater pupil involvement. Also included are two sheets: the first consists of 2 A5 printable unlabelled eye diagrams for sticking in books and the second a worksheet based on the contents of the PowerPoint.

KS3 Physics Lesson Resources - Light - Reflection (Lesson 2)

KS3 Physics Lesson Resources - Light - Reflection (Lesson 2)

This package contains resources intended to introduce the subject of Reflection The PowerPoint (made up of 7 slides) is carefully designed to introduce key scientific concepts regarding reflection including virtual images, specular and diffuse reflection, image distance. It includes learning objectives, a starter activity consisting of stimulus image with points for discussion/consideration and a mini practical for students to explore image distance for themselves. Diagrams contain simple animations to help explain key points. The summary worksheet (and mark scheme) also introduces students to the drawing of the normal as well as angles of incidence and reflection.

KS3 Physics Lesson Resources - Light - An Introduction To Light (Lesson 1)

KS3 Physics Lesson Resources - Light - An Introduction To Light (Lesson 1)

This PowerPoint of 11 slides covers numerous points to introduce the topic of light to a class. It includes learning objectives, a starter activity and introduces key concepts and scientific terms including luminous and non-luminous objects, transparent, transluscent and opaque, and also light speed. When paired with textbook questions this should prove sufficient for a single period lesson. Some elements include simple (I would prefer to say tastefully understated) animations and/or interactive elements to aid explanation of key concepts.

Biology A Level - Muscles - Sliding Filament Theory Cut & Stick Activity

Biology A Level - Muscles - Sliding Filament Theory Cut & Stick Activity

This resource consists of a two page worksheet. The first is a grid and the second is the tiles that should be cut out and stuck on the former to complete it. Cut and stick activities can be unpopular - especially at A-level - but my students have all agreed this is a great summary activity and a fantastic resource for later revision. The finished result is a single sided piece that works through the entire cycle of a single myosin head power stroke.

Succession: Sand Dunes cut and stick (A level resource)

Succession: Sand Dunes cut and stick (A level resource)

The resource consists of a page of tiles and a grid for sticking them on to which links seral stage to environmental conditions and the sand dune topography. An animated markscheme (PowerPoint) is also included which can be projected to help students with the task and/or used to aid discussion.
