B5 Transportation (Combined Science)

B5.1 TRANSPORT IN PLANTS

 

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:

For self-assessment questions, with exercises and discussions, just click on the correct topic at Biology GCSE & IGCSE Question Bank.

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 TRANSPORT IN HUMANS

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

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 GCSE from dhmcmillan

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:

Heart Structure and Function from Faiq Bin Zahid

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

Infographic from Compound Interest: Chemistry-of-Blood-Colours-v2.3

B6.1 RESPIRATION & ENERGY

What is aerobic respiration? a short (51s) introductory video from Clipbank.

Science Bank 8 (Biological Reactions): you only need Part 2 – Respiration (from 5m 20s to 9m 55s) and you only need to know about aerobic respiration:

B6.2 GAS EXCHANGE

Science Bank 22 (Body Parts): you just need Part 1 – The Lungs (to 5m 20s):

How do the Lungs work? – a three and a half minute TED-Ed lesson:

Gas Exchange – a 3m video on oxygen transport from lungs to cells. The Respiratory System – a 3m 30s video on how the respiratory system works. The Virtual Body – Circulation, Respiration & Breathing (a 19m video).

Respiratory system song:

B7.1 HORMONES

The only hormone we need to know about is adrenaline. Here GCSE Bitesize revises Hormones (7m 12s) in more detail than we need.

B7.2 TROPIC RESPONSES

We only need to know the first 28 slides:

Tropisms from Marthese Azzopardi

Science Bank 15: Part 3 covers Plant Tropisms (from 9m 25s to 14m 30s):

A 3 minute introduction to tropisms (from Twig World).

Plant Control – Paul Andersen explains how plants use hormones to respond to their environment. We only need to know about auxins (to 3m 40s).
