Disclaimer: These are online resources that I have found, They are not meant to be your only source of study, instead you can use them to your enhance your normal study. I don’t know what level these resources are aimed at, but I’ve tried to provide a range for a number of different topics.

The Body: Cells: Animals and Plants: Genetics: Evolution: Health: Other: Online Lessons and Guides:
  • Chemistry of life

  • Elements and atoms – elements and atoms, matter, elements and atoms, introduction to the atom, atomic number, atomic mass, and isotopes.

  • Cohesion And adhesion – capillary action and why we see a meniscus, surface tension, cohesion and adhesion in water

  • Temperature and state changes in water – LeBron asks why does sweating cool you down, evaporative cooling, heat of vaporisation of water and ethanol, specific heat of water, liquid water denser than ice, specific heat, heat of vaporisation, and density of water

  • Acids, bases and pH – autoionisation of water, Arrhenius definition of acids and bases, bronsted-Lowry definition of acits and bases, definition of pH, acids bases, pH and buffers

  • Cellular and molecular biology

  • Cells – diffusion and osmosis, nucleim membranes, ribosomes, eukaryotws and prokaryotes, endoplasmic reticulum and golgi bodies, chromosomes, chromatids, and chromatin.

  • Introduction to cell division - Fertilization terminology: gametes, zygotes, haploid and diploid, zygote differentiating into somatic and germ cells

  • Mitosis – interphase, mitosis, phases of mitosis, mitosis questions.

  • Meiosis – comparison of mitosis and meiosis, chromosomal crossover in meiosis 1, phases of meiosis 1, phases of meiosis 2.

  • Stem cells and cancer – embryonic stem cells, cancer.

  • Cellular respiration – ATP, ATP hydrolysis mechanism, introduction to cellular mechanism, oxidation and reduction review from biological point of view, oxidation and reduction in cellular respiration, glycolysis, krebs cycle, elctron transport chain, oxidative phosphorylation and chemiosmosis.

  • Photosynthesis – light reactions, photophosphorylation, calvin cycle, photorespiration, C-4 photosynthesis, cam plants

  • Human Biology:

  • Circulator and pulmonary systems – the lungs, red blood cells, circulatory system, haemoglobin.

  • The neuron and nervous system – neuron anatomy, sodium potassium pump, action potentials, salutatory conduction, neuronal synapses.

  • The kidney and nephron – kidney and nephonr, secondary active transport.

  • Muscles – myosin and actin, tropomyosin and troponin, role of sarcoplasmic reticulum in muscle cells, anatomy of skeletal muscle fibre.

  • Immunology – phagocytes, immune responses, b lymphocytes, antigen presenting cells and MHC II complexes, helper T cells, cytotoxic t cells and MHC I complexes, review of cells, inflammatory response.

  • Heredity and evolution

  • Evolution and natural selection – introduction, ape clarification, intelligent design and evolution, natural selection and the owl butterfly, variation in a spcies.

  • Heredity and genetics – introduction, Punnett squares, allele frequency, Hardy Weinberg equation, sex linked traits, DNA, RNA transcription and translation, alleles and genes.

  • Tree of life – taxonomy and the tree of life, species, bacteria, human prehistory

  • Crash Course

  • Biology and ecology – pollution, conservation, ecosystems, nitrogen cycle, history of life on earth, population growth.

  • (Spotlight Lessons): Ecology

  • Estimating Population Size – simulate mark and recapture by using small objects to trap and tag.  A simple formula will tell you what the overall population size is which can be verified by counting the objects in the bag.

  • Owl Pellet Dissection –  owl pellets are undigested bits of fur and bones  that owls regurgitate. Students can examine the contents, reconstruct the skeleton of the prey and make inferences about the owl’s diet.

  • Interpreting Ecological Data – examine charts, data tables  and graphs to answer questions about population size, growth, and carrying capacity.

  • Biome Project – as a group, investigate a biome and present to the class the main features, animal and plant species present and general climate.

  • Isopod Behavior Lab – collect isopods (pillbugs) and design a chamber to test their response to different environments, such as temperature, moisture, and substrate.
