Fantastic animated tutorials from McGraw Hill Education – Water Uptake, Mineral Uptake.

A 13m 43s video lesson covering all of 9.1 from Dan Rott:

Paul Andersen explains how nutrients and water are transported in plants in Plant Nutrition & Transport.

Here’s a simple transpiration animation & here’s a great animation in which you can change the factors that affect the rate of transpiration.

D4 The Heart (SL & HL)

 
Transport System from Stephen Taylor – thank you Mr Taylor (of iBiology).

Fantastic animated tutorials from McGraw Hill Education – the cardiac cycle, mechanical events of the cardiac cycle (pressure & volume changes etc) & the conducting system of the heart.

An animated, narrated tutorial on measuring blood pressure (from Sinauer Associates).

Click on ‘Cholesterol’ to see an Interactive Animation from Wiley on Cholesterol & Heart Disease and here is an excellent lesson from TED-Ed on on what is fat?

1.4 Membrane Transport

BioKnowledgy 1.4 Membrane transport from Chris Paine (at Dulwich College Shangai) – taken from his fabulous blog BioKnowledgy.

1.4 Membrane Transport notes to complete (created by Ms Green).

A 13m 35s video lesson from Dan Rott:

Some assessment statements are covered in videos by Stephanie Castle.

Click on ‘Cellular Transport’ to see an interactive animation from Wiley that covers diffusion, osmosis, passive transport & active transport. Or here for an animated, narrated tutorial on how molecules move across the cell membrane (from Sinauer Associates).

DIFFUSION

A short, simple animation demonstrating diffusion (from St Olaf) and here are two fantastic animated, narrated tutorials from McGraw Hill Education – how diffusion works & diffusion through cell membranes.

FACILITATED DIFFUSION

Short, simple animations demonstrating facilitated diffusion with a channel protein and with carrier proteins – three types: uniport, symport, & antiport  (from St Olaf).

An animated, narrated tutorial on the three types of carrier proteins (from Sinauer Associates).

Or here are is a fantastic animated, narrated tutorial from McGraw Hill Education – how facilitated diffusion works.

OSMOSIS

A short, simple animation demonstrating osmosis (from St Olaf) or here are two fantastic animated, narrated tutorials from McGraw Hill Education – osmosis & how osmosis works.

ACTIVE TRANSPORT

A short, simple animation demonstrating Secondary Active Transport – the Na/K pump coupled with the glucose/Na symport (from St Olaf).

ENDOCYTOSIS & EXOCYTOSIS

A short, simple animation demonstrating phagocytosis (from St Olaf) or here is a fantastic animated, narrated tutorial from McGraw Hill Education – Endocytosis & Exocytosis – which includes a quiz.

And here is an animated, narrated tutorial on vesicle budding &  fusing which also includes a quiz (from Sinauer Associates).

Here Paul Andersen gives you a brief introduction to The Cell Membrane.

Mr W’s Cell Membranes rap is good revision as is his Osmosis! rap.

In Crash Course Biology #5 – In Da Club – Membranes & Transport, Hank describes how cells regulate their contents and communicate with one another via mechanisms within the cell membrane.

6.2 The Blood System

A powerpoint from the OLD syllabus; much is still relevant.

A fantastic animated tutorial from McGraw Hill Education on the cardiac cycle.and here’s an animated, narrated tutorial on blood flow through the human heart (from Sinauer Associates).

Mr W’s Circulatory System rap and Mr W’s musical quiz on the Heart.

Paul Andersen surveys The Circulatory System in humans in an 11m 35s tutorial.

In Crash Course Biology #27 – Circulatory & Respiratory Systems, Hank takes us on a trip around the body – we follow the circulatory and respiratory systems.

B5.2 Transport in Humans

Mr Exham’s site has a fantastic section on Blood and Circulation: videos, animations, quizlets, worksheets – go here now!

For self-assessment questions, with exercises and discussions, just click on the correct topic at Biology GCSE & IGCSE Question Bank. The s-cool revision site lets you revise the topic, summarizes the topic & tests you on it. Skoool gives you a lesson, including progress questions, for each Biology topic but you’ll need sound on for it. GCSE Bitesize has revision pages (that take you through the topic), a test and an activity. 

B5.2 Revision notes in downloadable word format and here are the key terms and some definitions: Key Terms B5.2.

CIRCULATION & BLOOD VESSELS:

GCSE Bitesize – Blood Circulation covers how the heart circulates blood & the composition of blood (6m 35s).

Other videos include The Virtual Body – Circulation, Respiration & Breathing (19m), Science in Focus – Life Blood (19m 15s) & BBC Short Circuit Blood & Circulation (19m).

Various animations about heart & circulation problems can be found here.

BLOOD:

Blood video (a 3m 44s lesson) & Blood music video by Peter Weatherall – 3m 3s and very catchy! And here is a day in the life of a Red Blood Cell (a one minute cartoon) & here a white blood cell chases a bacterium (20s).

THE HEART:

Science Bank 22 (Body Parts): you just need Part 2 – the Heart (from 5m 20s to 10m 15s):

THE IMMUNE SYSTEM:

The Immune System is covered in the video The Virtual Body – the Immune System (19m), The Edward Jenner Story (a 2m 38s cartoon) & in this short video from The Virtual School:

B5.1 Transport in Plants

B5.1 Revision notes in downloadable word format and here are key terms and some definitions: Key Terms B5.1.

A nice short introduction to Plants, Growth & Transport (from Twig World):

TRANSPORT

Transport in plants in three and a half minutes:

Or how about a whole lesson from Mr Paul Andersen? He goes into more detail than we need (we have to know about Dicots but not Monocots), but he’s good:

The most amazing thing about trees (5m video).

TRANSPIRATION

More-detailed than we need but it’s good:

Mr Paul Andersen starts by defining transpiration as evaporation of water from a leaf. He then describes how a potometer can be used to measure the rate of transpiration in different environments:

How to use set-up a potometer: Transpiration: the power of the potometer, a 17m video from STEM Learning.

TRANSLOCATION

Here’s a 2m video on Phloem Loading (in a little more detail than we need).

XEROPHYTES

Specialized Leaves, a short 1m 39s video.
