  - Lesson 01 - What is in the human reproductive systems? Lesson Plan Lesson Title
    - T: Structure and function of the male reproductive systems:
      - Testes: Where sperm cells are produced. - KS3.B.20
    - T: - Scrotum: A bag of skin which holds the testes away from the body so the testes are cooler. - KS3.B.20

    - T: - Sperm duct: Tube which carries the semen to the penis. - KS3.B.20
    - T: - Penis: Allows insertion into female. - KS3.B.20
    - T: - Urethra: Tube which carries sperm out of the penis. - KS3.B.20
    - T: Structure and function of the female reproductive systems:
      - Ovary: Where eggs are stored and matured. - KS3.B.20
    - T: - Oviducts: Tube which carries eggs from the ovary to the Uterus. - KS3.B.20
    - T: - Uterus: Where the baby develops. - KS3.B.20
    - T: - Cervix: The opening of the Uterus. - KS3.B.20
    - T: - Vagina: Receives the semen. - KS3.B.20
    - T: During the Menstrual cycle the blood rich lining of the Uterus thickens in readiness for pregnancy. If not used the lining is shed during menstruation.

  - Lesson 02 - What are Gametes? Lesson Plan Lesson Title
    - W: gametes: cell structure linked to function
      
      Sperm Cells:
      - Tail: to be able to swim.
      - Pointed head: streamlined for swimming and entering egg.
      - Lots of mitrochondria: energy needed to swim, mitrochondria need to release energy through respiration. - KS3.B.20
    - W: gametes: cell structure linked to function
      
      Egg Cells:
      - Large food store for initial growth - KS3.B.20
    - T: Fertilisation occurs when the sperm's nucleus fuses with eggs nucleus.
      
      This forms a zygote. - KS3.B.20
    - W: Gametes only contain half the DNA of a 'normal' cell. - KS3.B.20
    - T: To result in a pregnancy fertilisation must occur in the oviduct tubes. - KS3.B.20
  - Lesson 03 - How does an offspring develop? Lesson Plan Lesson Title
    - T: The zygote copies and divides and itself to produce a ball of cells called a embryo. - KS3.B.20
    - T: A women becomes pregnant when the embryo implants in the blood rich lining of the Uterus. - KS3.B.20
    - T: The embryo develops into a fetus. It is called a fetus when it heart starts beating. - KS3.B.20
    - T: Part of the embryo develops into a placenta, which allows substances to cross from the mother's blood into the fetus, and vice versa. - KS3.B.20
    - T: The time spend in the uterus is called gestation period. During this time cells continue to copy and divide allowing the fetus to grow. - KS3.B.20
    - D: PLOT:
      Gestation period vs birth weight for animals - KS3.B.20
  - Lesson 04 - What happens during birth? Lesson Plan Lesson Title

    - T: DNA is a long molecule that contains the genetic information for an organism.
      
      DNA is in the form of a double helix of 2 strands, joined through base pairs. - KS3.B.34
      - Suggested Activity:
        Develop Analogy (Bridge Map)
        
        Base Pairs => Words
        DNA => Recipe
        Gene => Paragraph
        Chromosome => Chapter
        Nucleus => Recipe book
    - T: The order of the bases gives the code to create proteins/give characteristics. - KS3.B.34
    - T: Long strands of DNA are called chromosomes.
      
      Genes are sections of DNA that give instructions for a particular characteristic.
      
      Genes can be found at particular locations on the chromosome. - KS3.B.34
  - Lesson 09 - How was the structure of DNA discovered? Lesson Plan Lesson Title
    - T: Before the discovery of the DNA structure, Pauling had already discovered helical proteins and Chargaff had already discovered there were always equal numbers of bases A and T and also equal numbers of C and G. - KS3.B.34

    - T: Watson and Crick worked out the shape of the DNA double helix and how it could be replicated. - KS3.B.34
    - T: Franklin and Wilkins used the new technology of X-ray crystallography to make photographs of the DNA molecule and revealing its shape.
      
      Watson and Crick didnâ€™t properly acknowledge the research carried out by Franklin and Wilkins they used to come up with their discovery. - KS3.B.34
    - W: The factors needed for scientific understanding to progress including the improvements in technology and building on discoveries by other scientists. - KS3.B.34
  - Lesson 10 - What is Heredity? Lesson Plan Lesson Title
    - T: Heredity is the process by which genetic information is transmitted from one generation to the next. - KS3.B.33
    - T: A species is defined as a group of organisms who's genetic information is compatible such that their offspring can also reproduce. - KS3.B.35
    - T: Similar species can reproduce, creating sterile offspring. - KS3.B.35
      - Suggested Activity:
        Look at Ligers, Tigons; Zorse and Horbra etc.
        
        What out for photoshopped pictures.
    - T: Biodiversity is a measure of the number of species in an area. - KS3.B.39
    - W: the importance of maintaining biodiversity: means all the roles in the ecosystem are occupied, maintains genetic variation, the ecosystem has a greater stability, can save potential useful species from extinction. - KS3.B.39
      - Suggested Activity:

  - Lesson 11 - Progress Observation Opportunity Lesson Plan Lesson Title
    - T: the variation between species and between individuals of the same species meaning some organisms compete more successfully, which can drive natural selection - KS3.B.37
      - Suggested Activity:
        Get students to come up with a list of differences between people in the class.
        Are these caused by genetics or environmental factors?
        Create a list of genetic, environmental and both variations.
    - T: A species is defined as a group of organisms who's genetic information is compatible such that their offspring can also reproduce. - KS3.B.35
    - The differences between individuals within a species are called variation . - KS3.B.36
    - The variation between individuals within a species being continuous when there are (near) infinite number of possibilities. - KS3.B.36
    - Continuous variation is often measureable and with units. - KS3.B.36
      - Suggested Activity:
        Eg
        Hand span
        height
        weight
    - Discontinuous variation is often described by words or integers - KS3.B.36
    - The variation between individuals within a species being discontinuous when fits into a distinct categoriy - KS3.B.36
      - Suggested Activity:
        Eg
        Ear lobes: detached / attached
        Eye Colour
        Hair Colour

        Blood Group
        Number of legs
        
        COMPARE
        Foot length & shoe size
    - measurement and graphical representation of variation - KS3.B.36
      - Suggested Activity:
        Collect class data for height against no. of students and eye colour against number of students.
        Plot these results as graphs.
        Height (continuous variation) represented by a line graph.
        Eye colour (discontinuous variation) represented by bar graph.
  - Lesson 12 - Progress Reflection Lesson Plan Lesson Title
    - changes in the environment which may leave individuals within a species, and some entire species, less well adapted to compete successfully and reproduce, which in turn may lead to extinction - KS3.B.38
      - Suggested Activity:
        Skim, scan, summarise a text on the extinction of woolly mammoth, dinosaurs and dodo.
        
        Example table available to help students summarise the information.
