Kidneys and Osmoregulation Worksheet for A-level

Kidneys and Osmoregulation Worksheet for A-level

This double-sided worksheet consists of 5 multi-part comprehension and recall questions targeted at the knowledge and understanding required of AQA A level students. With full markscheme it can be used by yourself to assess students or can be peer/self assessed with the markscheme projected on the board, allowing quick afl in your lesson. It can also be used as a revision resource to check recall. It ties in perfectly with my Kidneys PowerPoint and Osmoregulation cut and stick activities also available on here/from my shop and also as part of my Kidneys for A-level bundle (link below).

ADH & Osmoregulation Cut and Stick Activity for A-level.

ADH & Osmoregulation Cut and Stick Activity for A-level.

This resource serves as an excellent summary of how ADH is used to regulate water reabsorption in the kidneys. Included is the template sheet, a sheet of 2 tile-sets to be cut out and a PowerPoint markscheme that can be projected and used to add tiles one at a time as a stimulus. The sheet includes the hypothalamus, pituitary gland, the action of ADH at the kidney and how this affects reabsorption in the collecting duct. Works equally well as an accompaniment to my PowerPoint on the Kidneys or as a stand-alone activity.

Oxygen Dissociation Curves Worksheet for A-level

Oxygen Dissociation Curves Worksheet for A-level

The resource consists of a double-sided worksheet comprising 6 examples of dissociation curves that may differ from a ‘standard’ curve for various reasons. Students need to read information on the situation in each case and predict, with detailed reasoning, the shape of the curve most likely for that case. This serves as a useful consolidation activity and also encourages a re-examination of students’ understanding of dissociation curves so is equally a useful revision resource. The accompanying mark scheme can be used for self/peer assessment and also to promote discussion in the classroom.

Kidneys PowerPoint for A-Level - Detailed slides on ultrafiltration, reabsorption and osmoregulation

Kidneys PowerPoint for A-Level - Detailed slides on ultrafiltration, reabsorption and osmoregulation

A detailed PowerPoint of 19 slides outlining kidney structure and function. Separate sections focus on ultrafiltration; reabsorption in the proximal convoluted tubule; water reabsorption in the Loop of Henle; and the role of the hypothalamus and posterior pituitary in releasing anti-diuretic hormone (ADH) and its affect on the permeability of the collecting duct in osmoregulation. Carefully presented diagrams outline the processes and explain in step-by-step annotations how these organs work. Multiple points of the PowerPoint are animated and you can navigate between slides/sections using a centralised menu. Also included is a printable notes sheet with diagrams from the PowerPoint integrated to facilitate student note-taking. Note - the preview function on TES mauls the PowerPoint slides - please be assured they work fine on both PC and Mac - I've tested them carefully.

Cracking the Genetic Code (A level) - Worksheet and Markscheme

Cracking the Genetic Code (A level) - Worksheet and Markscheme

The worksheet focuses on student understanding of the experiments carried out by Nirenberg and Khorana to determine which codons/triplets code for which amino acids. The worksheet details their investigations into the genetic code and provides a scaffold for students to draw conclusions from their original data. This is sound practice for questions of this type, which are becoming an increasingly frequent aspect of examinations. It also serves to consolidate on existing knowledge regarding the genetic code and is a useful reflection activity in its own right.

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.

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.

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.

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.

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.

GCSE Cells - Eukaryote & Prokaryote structure and scale.

GCSE Cells - Eukaryote & Prokaryote structure and scale.

This double sided worksheet covers the major structures within eukaryotic and prokaryotic cells and, when finished provides an excellent revision resource. It also references to other relevant topics including microscope types and scales.

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.
