The plant venus flytrap closes when fly sitting on.What characteristic of living thing is it?

Students may find this video interesting.

It shows how a Venus Flytrap responds to stimuli when an insect touches its fine hairs.

Hi! Smartmummy,
Do you mind take another clearer pic or maybe to type out the question and your DS's answer? The shot is a bit blur.

[smartmummy]

b) Give a reason for your answer in (a)

Hi smartmummy,

Your child’s answer is :
Group M is the group with things made out of one or more materials (then teacher’s arrow).

So I guess the teacher is looking for :-
Group M is the group of things made out of one or more materials while Ping Pong Ball is made out of only one material.

My suggested (but lenghty) answer would be:
The items are grouped according to the number of materials they are made out of. The things in Group M is made out of one or more materials while Ping Pong ball is made out of only one material. Therefore, it is grouped wrongly.

Hope to see other’s verification on my suggested answers.

Thank you.
