Lesson on proteins for AQA A Level Biology. Some slides taken from other free PowerPoints available on TES - thank you for sharing!
Covering:
Amino acids are the monomers from which proteins are made. The
general structure of an amino acid. The twenty amino acids that
are common in all organisms differ only in their side group.
A condensation reaction between two amino acids forms a
peptide bond.
• Dipeptides are formed by the condensation of two amino acids.
• Polypeptides are formed by the condensation of many amino acids.
A functional protein may contain one or more polypeptides.
The role of hydrogen bonds, ionic bonds and disulfide bridges in the
structure of proteins.
Proteins have a variety of functions within all living organisms. The
relationship between primary, secondary, tertiary and quaternary
structure, and protein function.
The biuret test for proteins.
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.
A science placemat to print in A3 and laminate. Stick a few down on tables or around the edge of the room so pupils can use them as a self-help resource. Includes naming common equipment, units, drawing graphs, designing experiment and other core skills for science at KS3/4.
Placemat is in Word format so feel free to edit it in any way you wish to suit your classes needs.
NOTE: check format before printing- format may be skewed if opening in different versions of word so check before printing, you may have to rearrange things slightly.
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!
Created for a low-attaining year 7 class but could be used across KS2-3.
This resource is a whole lesson, consisting of a worksheet and accompanying powerpoint presentation. There are 8 tasks designed to help pupils develop their understanding of the anatomy of flowering plants, including labelling diagrams, filling in the blanks, a hands on flower dissection, creative task and plenary questions.
To deliver this lesson you will need to provide flowers such as lillies or daffodils and print the worksheet.
This lesson is designed to follow a lesson on the homeostatic control of blood glucose concentration. The lesson explores type I and type II diabetes for AQA A level biology. Exam Qs are included but one worksheet referenced is on Kerboodle so cannot be shared. The end of the lesson introduces RP11.
Specification points:
The causes of types I and II diabetes and their control by insulin and/or manipulation of the diet.
Students should be able to evaluate the positions of health advisers and the food industry in relation to the increased incidence of type II diabetes.
Required practical 11: Production of a dilution series of a glucose solution and use of colorimetric techniques to produce a calibration curve with which to identify the concentration of glucose in an unknown ‘urine’ sample.
I created this broadsheet for students to revise the relevant areas of topic 1, cell biology (just the parts specified as making up the majority of exam content) - AQA 2022 Trilogy Higher
It covers 4.1.2 Cell division - it covers the cell cycle, mitosis and stem cells.
It can be used alongside BBC Bitesize revision pages if students have access to devices.
