Biology Scheme Of Work For SS3 (2022/2023)

Biology Scheme of work

The biology scheme of work for SS3 is a scheme for a science student in SS3. The scheme comprises what the student should be taught before partaking in Waec and all other external exams

First Term Biology Scheme Of Work For SS3

WEEKSTOPICS/CONTENTSACTIVITIES
1Development Of New Seeds
Definition of fertilization, the process of development of zygote in the flowering plant, Pistil, Stamen, Stem fertilization
Germination of seeds (Types and conditions necessary for germination
Essential factors affecting the development of organisms.
Meaning and difference between oviparity and viviparity 
The teacher provides the learners with dissected flames to show the parts involves in fertilization, demonstrates experiments on how to grow the seed, displays charts showing the various stages of the embryo depending on flowering plants, guides the learners to soak the seed in water and plant same in milk tins to observe types of germination and demonstrates the experiment on the condition necessary for germinating
Learners observe dissected flowers, noting the male and female parts, observe the slides and charts showing the growth of pollen and stages of embryo development, soak seeds in water and plant them in a milk tin and observe their germination with the lens, plant seeds in different categories and uproot to observe on different days finally place the planted seedlings under different conditions to identify the condition necessary for germination
2Fruits
Definition, classification, structure and types of fruits
Dispersal and Agent of dispersal of fruits and seeds.
Practical (Identification of different types of fruits and their classification) 
The teacher brings various kinds of fruits to the class, works with learners to sort and classify the fruits, and guides the learner to link the physical feature of fruits with their mode of disposal
Learners classified various kinds of fruits based on the teacher’s instruction, sort the fruits into various types, sort fruit into their mode of disposal
3Reproductive Behaviour In Animals
Courtship behaviour in animals. Pairing, territoriality, display of colours, and body party seasonal migration.
The teacher shows learners pictures of colourful birds and a preserved specimen of an agama lizard and takes the learners to where lizards bask to note the courtship behaviour
Learners observe and discuss animals, e.g. lizards, cocks, turkeys flexible, courtship behaviour
4Heredity (Genetics)
Transmission and expression of characters in organisms, heredity variations characters that can be transmitted and how they are transmitted, and how feelings are manifested from generation to generation.
The teacher discusses Mendel’s experiment with red and white flowered peas and guides the learners on how to cross between different genotypes
Learners observe experiments on cross-breeding using Drosophila and maize, and they compose their results with that of Mendel
5Chromosomes
Basis of heredity–location, structure, roles in the process of transmission of heredity characters from parent to offspring- progeny, Probability in genetics
Identify chromosomes that carry genes that are responsible for inherited characteristics, Note that chromosomes carry genes that are responsible for inherited character
6Application of the principles of heredity in agriculture
Improved varieties, diseased resistance varieties, in matching advice for couples about the sickle cell gene
The teacher shows learners a chart depicting the product of cross-fertilization and self –fertilization
learners should carry out the Mendel cross to explain offspring genotypes, note the medical advice for couples about sickle cell gene
7Variation And Evolution
morphological variation (physical appearance) which can be continuous (size weight height), discontinuous variation (colour of skin eye, coat of animal ) single fruits), physiological variation, behaviour, ability to roll the tongue, ability to taste phenylthiocarbamide (PTC), the difference in blood groups (A, B, AB, and O). Application of variation in crime detector (fingerprint of a dangerous weapon ), Blood transmission and Determination of patiently
Teachers measure the height of learners of the same age group, e.g., show a photograph of maize cobs, apples, and ripe pineapples, ask learners if they know their blood group, demonstrate the making of fingerprints and identify the different patterns made, e.g. arch loop wharf and compound. 
Learners’ records differed in heights and weights of learners in the same group, observed and recorded colour patterns on plants, attempted to roll the tongue, name their different blood groups, make fingerprints,s and note the difference.
8Adaptation For Survival
The progressive change in the anatomy of organisms using examples of features of organisms from water to land
The teacher shows life specimens of tadpoles in the external gill stage fish with internal gills and toads with lungs
Learners observe the progressive change of respirator surface in animals (structures).
9Structural Adaptation
Adaptive colouration and their functions, e.g. camouflage in chameleons, green snake in green grasses, bright colours of flowers to attract pollination, etc.
The teacher provides charts showing the colouration of animals and plants, organizes a visit to the zoo to see a peacock and a peahen and Provides a male agama lizard to show colouration
Learners note the colourful feathers of the peacock against the dull colour of the peahen and observe the band on the agama in contrast with the dull green colour of the female lizard.
10Features of Structural adaptation for obtaining food, e.g. proboscis for sucking sap in insects, Mimicry colours for searching mates for regulating body temperature, etc.Teachers provide charts showing structural adaptive features which enable them to protect and defend themselves against their enemies
Learners observe the materials showing the material showing to them about the structural adaptation for protection
11-13Revision, Examination and Recording
