5 encounters within 3 D&D campaigns I'm considering running

Getting closer to picking one! Also, these are in addition to the encounters I wrote earlier.

1. Murder at magic boarding school
1. Encountering a clue the authorities did not collect
2. Journalists arrive at the school
3. Classes are suspended
4. The school goes on lock down
5. Most of the staff is forbidden from speaking to students
2. The rest of the town has fallen asleep. How can these adventurers save their town (or are they the ones in danger?)
1. The team has the chance to investigate the stores of caffeinated beverages for the town
2. A driverless carriage arrives with mail
3. With an unguarded town, the team must decide how to acquire resources 
4. A storm is on the horizon, how will the team handle the townspeople asleep outside?
5. The team has a chance to climb the watchtower to see what the surrounding areas look like
3. A town's zoo has escaped. Can the party return all of the creatures and figure out what happened in the first place?
1. The team encounters protesters who want the zoo closed permanently
2. Quick-breeding animals have gotten into a local forest where they'll thrive
3. Alligator-like animals have gotten into the sewers
4. A predator is found at a pub with a seedy reputation
5. A journalist beings to follow the team
