1 Life cycles of flowering plants

1.4 Seed germination

We are going to:

• find out what seed germination is
• use knowledge and understanding to make predictions

• identify the conditions that seeds need to germinate

• say how to do a fair test investigation
• record observations in a table

• say why it is better to do the same test with more seeds

• make a conclusion from observations
• understand that we sometimes need to observe over time to obtain results

Getting started

Work with a partner. Imagine a friend of

yours wants to plant some seeds.
Make a help sheet to tell your friend

how to make sure the seeds will start

to grow. You can also draw pictures
on your help sheet.

How do seeds grow?

Seeds might look dead, but they are not. Seeds grow into new plants. There is a tiny

plant inside the seed that starts to grow when conditions – things that affect how
something happens – are right. The seed also has a food store.
