New IB Biology Pages

It has been a while since I have managed to update mrexham.com due to other work commitments, but as I approach revision time with my IB students it seems logical to create some resources that are useful for everyone at this stage.

Therefore I have made a new IB page for revision resources which can be found here.

I have made a quick IB revision quiz for Core topic 1 on cell biology to start with. This is designed to quickly assess your factual recall on this topic, and is a good way to remind yourself of all the little details you need to know.

There are plenty of skills required to get a 7 in IB Biology such as; data interpretation, evaluation, application and practical science understanding to name just a few but if you don’t know these key facts then you don’t have the foundations needed for these higher level skills.

I will be posting similar tests for all the core topics over the next few weeks so stay tuned!

You will also find a very useful resource covering the 7 key practicals you should have completed.

Many of you will also be carrying out your Internal Assessment projects at the moment so I have created a page to help you with writing that up. It can be found here.

I plan on blogging more about the IA in the future as I am marking my classes now and have learnt a lot about going through the process for the first time this year.

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!
