- Lesson 02 - What are Gametes? Lesson Plan Lesson Title
- 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: 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

- Suggested Activity:
- 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
- Suggested Activity:
- 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
- W: In size order the genetic information is arranged as follow:
- 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: 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 didn’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
