Reproduction and variation

This lesson introduces the gametes and the male and female reproductive systems.

Human Reproductive System

This lesson describes how human reproduction occurs, including the key events of fertilisation and implantation, and also looks at cell division.

Fertilisation

This lesson describes the process of gestation, including development of the foetus, risk factors and looking at data.

Gestation

This lesson looks at the risks of smoking and drinking alcohol during pregnancy, along with exploring data and graphs.

Risk Factors during Gestation

This lesson describes the process of birth in humans and looks at differences in numbers of offspring between different animals.

Birth

This lesson looks at the changes that occur in males and females during puberty with a focus on the main events in the menstrual cycle.

Puberty and the Menstrual Cycle

Revision lesson. This lesson recaps the processes that occur in the making of a baby, then looks at how the chromosome number is maintained through sexual reproduction.

Reproduction Revision 1

This lesson looks at the embryologist Jean Purdy, her contribution to fertility treatment and the uses of her discoveries.

Jean Purdy and Fertility Treatment

This lesson looks at the main parts of the flower and the process of pollination. This draws comparisons with human reproduction.

Plant Reproduction

This lesson follows the previous and discusses the mechanisms of fertilisation and seed formation in plants.

Seed Formation and Dispersal

This lesson focuses on an investigation into seed dispersal, with a focus on the different variables that affect seed dispersal.

Practical: Seed Dispersal

The lesson looks at the definition of a species, different forms of variation and data on variation.

Variation

This lesson looks at an investigation into human variation, focusing on an investigation into variation in human height and handspan. The lesson also focuses on graph plotting skills.

Practical: Human Variation

This lesson looks at why variation is important in humans and in different populations of animals and plants.

Why is variation important?

This lesson recaps the reproduction process in plants and compares it to the reproduction process in humans.
