A way of displaying results to make them easier to read and interpret.

Variables that have values that are labels.

A value that is a number; these variables may display trends.

Seed dispersal: data analysis

Pupils will learn about what the genome is, what it’s made of and where it’s stored, more detail about the chemical structure of DNA, and the relationship between an organism’s genome and its phenotype.

Pupils learned about changes experienced in puberty, the male and female reproductive systems, the menstrual cycle, sexual intercourse, gametes and fertilisation, gestation and birth, and the dangers of smoking, drinking and drugs during pregnancy.

This unit explores plant reproduction, including flower structure, pollination, fertilisation, seed formation, and dispersal mechanisms. It highlights the role of insect pollination in food security. Focus is on planning and conducting enquiries, and ensuring reliable observations.

Reproduction in plants

How should experimental results be recorded?

the amount of salt added to water used to water plants

presence or absence of soil when germinating seeds

different temperatures used to germinate seedlings

Which of these are examples of categoric data?

Which factors do **not** affect seed germination?

from 0-60 ml, the number of cress seeds germinating increases.

from 80-100 ml, the number of cress seeds germinating then decreases.

from 60-100 ml, the number of cress seeds germinating then decreases.

from 0-40 ml, the number of cress seeds germinating increases.

What are the trends in these results? As the volume of water increases ...

explanation of results using scientific knowledge

What is the independent variable in an investigation into the effect of temperature on plant growth.

Put these stages of development into the correct order.

Where do we record our results during a scientific experiment?

Match the gamete to where it is produced.

Andeep: Germination is when a seed is dispersed by an animal.

Sam: Germination is when a seed is made through fertilisation.

Alex: Germination is when a seed produces a food store that it will use to grow.

Laura: Germination is when a seed sprouts and it is growing.
