Question

germinating bean seed
 
 
Look carefully at the pictures.
What starts growing first?

    • The leaves

    • The flowers

    • The roots.

Task administration: 
This task is completed online and has auto-marking displayed to students.
 
One trial teacher used this task as a quick check of students' knowledge of germination before beginning teaching.
She found through the task and discussion with students that they knew more than she had thought. This information was used to plan for activities that were appropriate for extending her students.

What starts growing first? Roots
Diagnostic and formative information: 

Most Year 3 students were able to complete this task accurately, even when they had no background knowledge of growing seeds. Some students may be applying logical thinking (a useful skill in science) to complete the sequence rather than actually "knowing".

To find out what cues students are using ask them to give reasons for selecting the order they have.

Next steps: 

The following activities relate to Capability 1: Gather and Interpret data

Observation

Get students to look carefully at the pictures in sequence and describe what happens to the seed.

Inference

Ask:

  • Why do you think the roots grow before the stem and leaves?
  • What do you think may have happened to the bean seed?
  • Do you think all seeds grow in this order? Why do you think this (what evidence do you have?)
  • How could we find out?

The following activity relates to Capability 1, and Capability 2: Use Evidence

Investigating

Grow a bean seed (or other seeds) in a clear container so students can see the germination process.  (You could use Activity 1, page 15 in Section 3 of the BSC booklet, Flowers, fruits, and seeds.)

Does the evidence they collect confirm or disconfirm their ideas?
