A picture showing a teddy bear and a Polar bear
Question : Write down a difference between the teddy bear and the polar bar. (Do not compare their sizes, colors and shapes)

Ans 1 - Teddy bear is a non living thing but Polar bear is a living thing

Ans 2 - Teddy bear cannot die but the polar bear can die.

Pls let me know which answer deserves a full 2 marks?
Thanks

I think is ans 2. or other characters of living or non-living things. such as can grow, need water, food and air, etc.

Does anyone know that a grasshopper can fly or not?



Thanks!

I think scientifically, ans 1 is right, but better would be either 1) ability to move from place to place 2) the need for air, food and water to grow 3)ability to reproduce 4)ability to respond to stimuli. I told my girl, for such question, go straight to the characteristics difference, cannot be wrong.

No.

Thanks for your reply.


By the way, which source do you usually use to find out such science questions? I also like to check http://en.wikipedia.org/wiki/. but my DD told me, \" my teacher says the info in this website is not always true!\" :roll:

Hi,
I posted your question to my child and he immediately said that his teacher told the whole class not to simply write 'living/non-living thing' as the answer for such questions. They were told to state characteristics or what are their physical attributes (eg bat vs bird, both have wings).
Science is indeed tricky. :roll:

Did ans 2 get 2 marks?
