There is a picture of a Bee and a Bird.


Q: State 2 similarities. (do not describe shape or size).

Ans Key: Both have wings and both can fly.
Child's Ans: Both have wings and both lay eggs to reproduce.

My question is, is the child's second answer acceptable since only Queen bees lay eggs and not all bees lay eggs.

Hi

Sometimes, such questions can be quite confusing.

In answering such questions, students should state the similarities that can be observed from the diagram. Do not rely on background or prior knowledge.

My suggested answer ----- Both have wings, both have legs (if legs are shown in the picture), both have eyes (if eyes are shown).

Best wishes

huh?
If the child state,'Both are living things and need air, food and water to survive', can it be considered as correct too? Can characteristics of living things be used for all questions relating to similarities of 2 living things, or must it be physical similarities observed from the picture given? If need to observe from picture given, on a similar question, there is a picture of a mouldy bread and a bird's nest fern.
Q: State 2 similarities.
Answer Key: Both reproduce using spores and both are non-flowering plants. (these answers cannot be physically concluded from the picture and need background knowledge).
Child's Ans: Both use spores to reproduce and both need air, food and water to survive.

It is frustrating to know that the child's concept is correct but answering technique may be wrong....or that I may be teaching my child the wrong thing.

Hi

Which testpaper is this question from?
Is there a link to the original question?

Sometimes, together with the diagram, there may may some leads guiding you to the answers.

Look at the context of the questions and apply the concepts accordingly.

For examples,

1) State the difference between how a balsam plant and mould reproduce.

2) How do the fungi and the fern in the pictures above obtain food?

3) How do a fungi and fern reproduce?

4) Give one difference between the two organisms shown above in terms
of their nutrition.

5) Describe how each animal would respond to a hunter firing a shot in terms of its movement.

6) Write down two characteristics of the above two animals which show that they belong to the same group of animals.

7) List one similarity in their appearance.

8)State 2 characteristics to show that it is not a bird.

Hi teh-oh

Is mould a plant? I thought it is a fungus.

Mould is a fungus.

Sorry, I rechecked the answers. Their answers are that both reproduce using spores; Both do not bear flowers.

Thanks for the notes.
The original questions is this.

Actual ans from Ans Key: both reproduce from spores; They do not bear flowers.

Can we state characteristics of living things in the answer?

Hi teh-oh

In my opinion, their answer \"both do not bear flowers\" is not acceptable because we cannot conclude \"bear\" from the picture i.e. maybe they can bear flowers but the picture happened to be taken after their flowers have been removed.

However, it will be ok to say that \"both do not have flower\" i.e. as shown in the picture.

I think characteristics of living things are also not ok because we cannot tell from a picture that something is alive.

teh_oh:

Can characteristics of living things be used for all questions relating to similarities of 2 living things, or must it be physical similarities observed from the picture given?

It depends on the context of the question. Sometimes, there are keywords leading you to the right direction.

For example.

1)Based on the pictures only. Write down one similarity and one difference between the body parts of the two animals. (Do not compare colour, shape and size).

2)From the diagram above, state one physical similarity between A and B.

teh_oh:

If the child state,'Both are living things and need air, food and water to survive', can it be considered as correct too?

Avoid using general statement like \"Both are living things and need air, food and water to survive\".

List down the similarities and differences in characteristics between the objects you are comparing.

Choose the characteristics that can be compared eg number of legs, body covering, type of movement and method of reproduction.

Look out for keywords guiding you in the question, if applicable,as shown in my earlier post.

Such questions on comparing are common in P3 science but the good news is you don’t see many such questions in upper primary science.
