PowerPoint for a whole lesson on the endocrine system, control of blood glucose and diabetes - for AQA Trilogy or Biology. 2-3 lessons worth of content.
Specification points:
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.
Blood glucose concentration is monitored and controlled by the
pancreas.
If the blood glucose concentration is too high, the pancreas
produces the hormone insulin that causes glucose to move from the
blood into the cells. In liver and muscle cells excess glucose is
converted to glycogen for storage.
Students should be able to explain how insulin controls blood
glucose (sugar) levels in the body.
Type 1 diabetes is a disorder in which the pancreas fails to produce
sufficient insulin. It is characterised by uncontrolled high blood
glucose levels and is normally treated with insulin injections.
In Type 2 diabetes the body cells no longer respond to insulin
produced by the pancreas. A carbohydrate controlled diet and an
exercise regime are common treatments. Obesity is a risk factor for
Type 2 diabetes.
Students should be able to compare Type 1 and Type 2 diabetes
and explain how they can be treated
Whole lesson about binary fission using the learning loop approach. Created for AQA GCSE Biology, but could be adapted.
Feel free to feedback if you use this resource :)
A worksheet I created to guide less confident students through calibrating and using a graticule to measure a cell. Suitable for GCSE and A Level Biology. I teach AQA but could be used for other specifications.
AT d - use of light microscope at high power and low power, including use of a graticule
AQA required practical 12:
Investigation into the effect of a named environmental factor on the distribution of a given species.
Template and accompanying PowerPoint presentation for students to plan and write up their investigation for practical 12.
Designed to be conducted over a 2 hour session with an onsight investigation.
Exam questions included have been taken from https://www.tes.com/member/m_adanah who also provides a free template for this practical and many others.
Specification points covered:
The size of a population can be estimated using:
• randomly placed quadrats, or quadrats along a belt transect, for slow-moving or non-motile organisms
• the mark-release-recapture method for motile organisms. The assumptions made when using the mark-release-recapture method
Students could:
• investigate the distribution of organisms in a named habitat using randomly placed frame quadrats, or a belt transect
• use both percentage cover and frequency as measures of abundance of a sessile species.
Students could use the mark-release-recapture method to investigate the abundance of a motile species.
Get hands on with science at home! Make your own skittle rainbow using resources you most likely already have at home, or you can easily purchase from a supermarket.
A fun activity that most primary and secondary students can engage with (ideally suited to KS2/KS3). Includes a list of resources, easy to follow method, scientific description of how it works, things to think about and questions to answer.
Please comment if you have any questions or feedback.
Created as a whole class activity for Biology Week (2018 but could easily be adapted). Students make giant organelles and assemble them into a giant cell.
Very open activity, created for a nurture/SEN year 8 class but could be adapted for any KS3 science.
A collection of extracurricular competitions, books and events for A-level biology students. These opportunities could all be used to enhance students UCAS personal statements and explore their passion for biology outside of the classroom.
Available as a powerpoint and pdf to share with students.
Feel free to comment anything you think should be added!
