PowerPoint presentation on species, courtship behaviour and classification - used for AQA A Level Biology (2 hour lesson) but could be easily adapted.
Topic 3.4.5
Specification points covered:
Two organisms belong to the same species if they are able to produce
fertile offspring. Courtship behaviour as a necessary precursor to
successful mating. The role of courtship in species recognition.
A phylogenetic classification system attempts to arrange species
into groups based on their evolutionary origins and relationships.
It uses a hierarchy in which smaller groups are placed within larger
groups, with no overlap between groups. Each group is called a
taxon (plural taxa).
One hierarchy comprises the taxa: domain, kingdom, phylum, class,
order, family, genus and species.
Each species is universally identified by a binomial consisting of the
name of its genus and species, eg, Homo sapiens.
A full lesson PowerPoint for AQA A Level Biology on the structure of cell membranes.
3.2.3 Transport across cell membranes
The basic structure of all cell membranes, including cell-surface
membranes and the membranes around the cell organelles of
eukaryotes, is the same.
The arrangement and any movement of phospholipids, proteins,
glycoproteins and glycolipids in the fluid-mosaic model of
membrane structure. Cholesterol may also be present in cell
membranes where it restricts the movement of other molecules
making up the membrane.
PowerPoint for a complete lesson on transport across membranes, focussing on simple and facilitated diffusion for AQA A Level Biology.
3.2.3 Transport across cell membranes
Movement across membranes occurs by:
• simple diffusion (involving limitations imposed by the nature
of the phospholipid bilayer)
• facilitated diffusion (involving the roles of carrier proteins and
channel proteins)
Powerpoint presentation for a lesson introducing the hormonal control of blood glucose concentration. Written for AQA A-level biology but easily adapted.
Specification points covered:
The factors that influence blood glucose concentration.
The role of the liver in glycogenesis, glycogenolysis and
gluconeogenesis.
The action of insulin by:
• attaching to receptors on the surfaces of target cells
• controlling the uptake of glucose by regulating the inclusion of
channel proteins in the surface membranes of target cells
• activating enzymes involved in the conversion of glucose to
glycogen.
The action of glucagon by:
• attaching to receptors on the surfaces of target cells
• activating enzymes involved in the conversion of glycogen to
glucose
• activating enzymes involved in the conversion of glycerol and
amino acids into glucose.
Does not cover the role of adrenaline or the second messenger model.
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.
PowerPoint presentation on the effect of temperature on rate of reaction for GCSE Chemistry - Rate of Reaction AQA
Full lesson using learning loop format.
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.
Worksheet for balancing chemical equations. Used as a starter after a lesson on balancing equations. Pupils balance the equations using m&m's- they place the sweets in the blue boxes beneath the equations to visually represent each atom. Used about 3 share bags of m&m's with a class working in pairs. Delivered to a year 8 class but suitable for KS4 too.
Whole lesson about binary fission using the learning loop approach. Created for AQA GCSE Biology, but could be adapted.

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.
