Is it okay to answer science test questions asking for reasons, to start with "Because . . ."?

Answer 1

It's silly, but most teachers won't accept sentences that start wtih because. However, if you are talking about a standardized test, it's usually okay as long as you make sure to keep it a complete sentence:

"Because of the nature of yadda yadda, the this mixed with the that resulted in bla bla bla."

That's a complete sentence. Answering a question with:

"Because this was mixed with that," is not.

"Because this mixed with that results in bla bla bla," is even questionable.

Answer 2

Teachers very often tell students not to answer with sentences that start with "because". Because people often don't end up writing a complete sentence when using that starting word, it is wide to avoid it at the start of a sentence.

Answer 3

I'm surprised your teacher hasn't told you.
You should not begin your answer with 'because'. You should make every sentence a proper, complete sentence.
'The reason why hot air rises and cold air sinks is ...'
'Glass will break under pressure because...'
.

Answer 4

i think it is because you have to have cause and effect

and if they are looking for the way you feel ?but as long as the sentence sounds right

as long as it sound right and makes sense you should be fine
