It is more usual for adverbs like "yesterday" to go at the beginning or end of sentences like this.
We went to zoo and we saw a big oxen.
Passive. The subject, "children," is not doing the action. Also, a sentence is passive when a form of the verb "to be" is followed by a past participle- in this sentence it is "were taken." To make the sentence active, it would have to state "Five children went to the zoo" or "Someone took five children to the zoo."

Yes, that is the adverb use of the word yesterday, telling when the action occurred. Some example uses: Adverb: He returned yesterday. I wasn't born yesterday. Yesterday it was on the news. Noun: They play the songs of yesterday. Yesterday's worries are gone today. It was on yesterday's news. Noun: "Yesterday" by John Lennon and Paul McCartney Adverb: "Yesterday, all my troubles seemed so far away..."
If you are talking about zoos in general, then no, it should not be capitalized. However, if you are talking about a particular zoo then it should be capitalized. An example would be: We went to the San Francisco Zoo today. This sentence is written with correct punctuation.
