IGCSE Revision Diagrams

One of the most important parts of IGCSE Biology is to be familiar with the key diagrams. I have therefore created a great revision PowerPoint that contains the 25 most important diagrams on individual easy print slides. Also included are all the answers. If you are a teacher these are great for testing your class, if you are a student you can print multiple copies and try them until you get them all right. Click on the image below to purchase this new resource:

You can download a free diagram of the heart by clicking this link.

Included in the presentation are diagrams for: the kidney, urinary system, digestive system, reproductive system, the leaf, the eye, a motor neurone, the circulatory system, plant cell, animal cell, sperm cell, menstrual cycle, nitrogen cycle and many more.

Need a new way to revise?

Bored of making flash cards? Tired of writing out notes? Why not try mind mapping? There are many reasons why drawing a mind map can be a useful way to learn. Just look at this list of the top 100 reasons to mind map compiled by mind mapping guru Paul Foreman. Paul has made a great mind map to give you some help getting started. You can also see more of Paul’s mind maps by visiting his website: http://www.mindmapinspiration.co.uk/#.

Try Mind MappingBelow is a mind map of the entire F211 AS Biology unit that I made with my students in a lesson this week.

Why not choose a topic for yourself and see if you can make a mind map using all the key terms, you could even add some diagrams as well. Alternatively, if you want to do a mind map on the computer there is plenty of mind mapping software available, but a good free one is FreeMind. You can watch this YouTube tutorial to help you get to grips with the FreeMind software.

New revision tests now available

Three more revision tests have now been uploaded to the website, one for IGCSE, one for AS, and one for A2. Download them from SlideShare, complete them, use the textbook to mark them, write out anything you get wrong on the revision tracker, and then repeat the test every couple of days until you are getting close to full marks!

Go to IGCSE revision to find a test for Section C: Plant Physiology. 

Go to AS revision to find a test for F211 Unit 1: Module 2 – Exchange, Animal Transport and Plant Transport.

Go to A2 revision to find a test for F214 Unit 1: Module 2 – Excretion.

As always these tests have been created using the relevant textbooks so the answers should be easy to look up. However, if you’d like the answers for any of the tests available on mrexham.com just send me an email.

Need help with revision?

Over the next month I will be posting various resources to help you revise for your exams. This will include hints, tips, videos, summaries, tests and planners. Once they have been posted you will also be able to find them on the relevant pages.

IGCSE Biology Revision

OCR AS Biology Revision

OCR A2 Biology Revision

The first resource, available to download now, is a revision tracker. It can be used for any subject but is particularly useful when revising for a factual subject such as Biology. Every time you complete a test or a past paper question, you should write down anything you get wrong on the tracker. This will allow you to keep a note of your weakest topics and help you to focus your revision in the weeks leading up to your exam or test.

I have also posted an IGCSE revision quiz for the whole of Section B: Human Physiology. The quiz takes about 30 minutes to complete and I’d recommend doing it several times as it’s a really effective way to improve your factual recall. I wrote the the quiz using the Edexcel textbook so all the answers can be found there.

Please write in the comments below if you’ve found these helpful, or if there are any other revision resources that you’d like me to create.

It’s Earth Day

On April 22nd over a billion people around the world will be taking part in Earth Day. This is an opportunity for each and every member of the planet to think about the biosphere and what we should be doing to help preserve it. This year’s theme is The Face Of Climate Change and Earth Day organisers are collecting and displaying images of people, animals, and places that are directly affected or threatened by climate change.

To join the movement just upload your photos depicting The Face of Climate Change and spread the word on social media: #faceofclimate.

If you are teacher you can incorporate Earth Day into your lessons. The TES have a whole host of useful teaching resources that have been hand picked to help students understand the planet and how to sustain it for the future. Just click here to access them.

No Smoking Day 2013

Today is officially No Smoking Day, so if you want to swap your fags for swag check out the WeQuit website for information, support and tips to help you kick the habit for good.

No Smoking Day 2013 v2

When I was at school smoking was everywhere. At 16 you could legally buy cigarettes, smoking was allowed inside pubs and clubs, tobacco was advertised on billboards, and tobacco brands were the prominent sponsors of Formula 1. However, times have now changed and it was only reported in the news last week that UK Ministers will soon be introducing plain packaging for cigarettes and a ban on smoking in cars carrying passengers under 16.

However, two-thirds of smokers start smoking before the age of 18, and studies show that just one cigarette a month is enough to get teenagers addicted for life. So if it’s young people who start smoking, the big question is will any of these changes deter school children from starting the habit in the first place? Tell me what you think by commenting below.

And if you’re unsure as to how smoking harms the body then why don’t you watch Gunther von Hagens, of Bodyworlds fame, explain the dangers of smoking in the video below.

What’s inside a cell?

Sometimes it’s hard to imagine what goes on inside a cell from a basic 2D diagram in a textbook.TheresaKnott_Microscope

If you are revising for your AS Biology exams then I’d recommend downloading the app iCell® which can be used on the iPhone, iPod touch, iPad, or Android device.

It gives you an amazing interactive 3D view inside three different types of cell – an animal cell, a plant cell and a bacteria cell. This means that you can easily compare the differences between eukaryotes and prokaryotes.

I like the way that you can you can click on the organelles to find out more information about them. You can also rotate the cell and use your finger to zoom in and out.

Give it a go!

Suffering from a broken heart?

heartIt’s Valentine’s day! A day to celebrate being in love. However, not everyone has that someone special. Maybe you’re suffering from a broken heart. The good news is that it can’t be as badly broken as the sheep’s heart I recently dissected.

You can view my dissection, which demonstrates the major structures found in the heart, on my YouTube channel. Or maybe try my ‘flipped’ lesson on TED-Ed.

I will be posting my next dissection, a pig eye, in a few weeks time!
