20 slides covering Stem cells.
By the end of the powerpoint students would have covered:
A stem cell is an undifferentiated cell of an organism which is capable of giving rise to many more cells of the same type, and from which certain other cells can arise from differentiation.
Students should be able to describe the function of stem cells in embryos, in adult animals and in the meristems in plants.
Stem cells from human embryos can be cloned and made to differentiate into most different types of human cells.
Stem cells from adult bone marrow can form many types of cells including blood cells.
Meristem tissue in plants can differentiate into any type of plant cell, throughout the life of the plant.
Knowledge and understanding of stem cell techniques are not required.
Treatment with stem cells may be able to help conditions such as diabetes and paralysis.
In therapeutic cloning an embryo is produced with the same genes as the patient. Stem cells from the embryo are not rejected by the patient’s body so they may be used for medical treatment.
The use of stem cells has potential risks such as transfer of viral infection, and some people have ethical or religious objections.
Stem cells from meristems in plants can be used to produce clones of plants quickly and economically.
• Rare species can be cloned to protect from extinction.
• Crop plants with special features such as disease resistance can be cloned to produce large numbers of identical plants for farmers.

17 slides covering The Brain.
By the end of the powerpoint students would have covered:
4.5.2.2 The brain (biology only)
The brain controls complex behaviour. It is made of billions of interconnected neurones and has different regions that carry out different functions.
Students should be able to identify the cerebral cortex, cerebellum and medulla on a diagram of the brain, and describe their functions.
(HT only) Students should be able to explain some of the difficulties of investigating brain function and treating brain damage and disease.
(HT only) Neuroscientists have been able to map the regions of the brain to particular functions by studying patients with brain damage, electrically stimulating different parts of the brain and using MRI scanning techniques. The complexity and delicacy of the brain makes investigating and treating brain disorders very difficult.

25 slides covering the human endocrine system.
By the end of the powerpoint students would have covered:
**4.5.3.1 Human endocrine system **
Students should be able to describe the principles of hormonal coordination and control by the human endocrine system.
The endocrine system is composed of glands which secrete chemicals called hormones directly into the bloodstream. The blood carries the hormone to a target organ where it produces an effect. Compared to the nervous system the effects are slower but act for longer.
The pituitary gland in the brain is a ‘master gland’ which secretes several hormones into the blood in response to body conditions. These hormones in turn act on other glands to stimulate other hormones to be released to bring about effects.
Students should be able to identify the position of the following on a diagram of the human body:
pituitary gland
pancreas
thyroid
adrenal gland
ovary
testes.

24 slides covering Discovery and development of drugs
By the end of the powerpoint students would have covered:
Students should be able to describe the process of discovery and development of potential new medicines, including preclinical and clinical testing.
Traditionally drugs were extracted from plants and microorganisms.
• The heart drug digitalis originates from foxgloves.
• The painkiller aspirin originates from willow.
• Penicillin was discovered by Alexander Fleming from the Penicillium mould.
Most new drugs are synthesised by chemists in the pharmaceutical industry. However, the starting point may still be a chemical extracted from a plant.
New medical drugs have to be tested and trialled before being used to check that they are safe and effective.
New drugs are extensively tested for toxicity, efficacy and dose.
Preclinical testing is done in a laboratory using cells, tissues and live animals.
Clinical trials use healthy volunteers and patients.
• Very low doses of the drug are given at the start of the clinical trial.
• If the drug is found to be safe, further clinical trials are carried out to find the optimum dose for the drug.
• In double blind trials, some patients are given a placebo.

22 slides covering Microscopy:
By the end of the powerpoint students would have covered (includes a required practical):
Students should be able to:
understand how microscopy techniques have developed over time
explain how electron microscopy has increased understanding of sub-cellular structures.
Limited to the differences in magnification and resolution.
An electron microscope has much higher magnification and resolving power than a light microscope. This means that it can be used to study cells in much finer detail. This has enabled biologists to see and understand many more sub-cellular structures.
Students should be able to carry out calculations involving magnification, real size and image size using the formula:
magnification = size of image
size of real object
Students should be able to express answers in standard form if appropriate.
Required practical activity 1: use a light microscope to observe, draw and label a selection of plant and animal cells. A magnification scale must be included.
