At the end of this unit
in terms of scientific enquiry
most pupils will: select information about reproduction from secondary sources; present and interpret data about growth in bar charts and graphs, indicating whether increasing the sample they used would have improved the work
some pupils will not have made so much progress and will: with help, find information from selected secondary sources and present data in tables and bar charts
some pupils will have progressed further and will: explain whether the sample size in their investigation of growth was sufficient for comparisons to be made with national data and describe how reproduction was explained before the role of cells was understood
in terms of life processes and living things
most pupils will: identify and name the main reproductive organs and describe their functions; describe fertilisation as the fusion of two cell nuclei; describe egg and sperm cells; explain how the foetus obtains the materials it needs for growth; describe differences between the gestation periods and the independence of the young of humans and other mammals and describe the menstrual cycle
some pupils will not have made so much progress and will: identify and name the main reproductive organs; describe fertilisation as the fusion of egg and sperm and identify the importance of the placenta in supplying food for a developing foetus
some pupils will have progressed further and will: explain how egg and sperm cells are specialised, and describe how they carry the information for development of a new life
