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."
Active because The subject (the dog) caught the object (the ball). The passive term would be, the ball was caught by the dog.

In active sentences the subject or actor (the doer of the action of the verb) comes at the before the verb eg: The dog chased the cat. In this sentence the dog is the doer of the action 'chased'. Passive sentences allow us to put some thing else that is not the subject in the position of the subject eg: The cat was chased (by the mouse). The actor/agent 'by the mouse' - can be left out
In active voice, the subject of the sentence performs the action, while in passive voice, the subject receives the action. For example, in active voice "The cat chased the mouse," the cat is the subject performing the action. In passive voice, the sentence would be "The mouse was chased by the cat," where the mouse is the subject receiving the action.

The active and passive voices are used to show what receives or initiates the action in a sentence. With a passive voice, the subject receives the action: "The glass was knocked off the table." In the active voice, the subject initiates the action: "I knocked the glass off the table." The passive voice is often criticized as a way of de-emphasizing the actor, but it is useful, particularly if the actor is unknown, or you.
