I don't have kids, but I have a doozy of a story from my childhood!
I was in 7th grade. It was the 1994-95 school year. There was NO INTERNET yet. Most families didn't even have a computer at home.
Our school decided that we were going to do what they called the "World's Fair Project". This was the first year they were doing this project. The entire grade was split up into groups of four and each group was assigned a country. There was at least 200 kids in my class, so that's over 50 different countries! My group was assigned The Czech Republic.
We were given semester long assignments related to our country in every class except for math. It wasn't just writing reports with facts and stats. We had to cook food from our country. We had to do art projects to recreate art from that country. One kid from each group had to SEW THE FLAG of the country!
But the big thing that really got the parents in an uproar was that each group was required to interview TWO people that had visited their assigned country! I got lucky. My dad had a cousin that was a university professor. She had visited Czech. But good luck finding somebody that has visited Chad without the internet.
When the school was flooded with phone calls from angry parents, they assumed we put our parents up to it to try to get out of doing our homework. They told us that if we didn't know somebody that visited our country, we needed to run an ad in the newspaper until we found someone! They eventually lower the requirement to interviewing one person, but wouldn't drop it completely.
It was so bad that all the churches in town got involved. They were reaching out to their congregations and printing lists of countries needed in their weekly bulletins.
A lot of kids with more obscure countries were struggling to find enough facts and stats to satisfy to project's requirements. I was one of the lucky ones that had a computer at home. I had a computer program that had a ton of information on hundreds of countries. One of my biggest bullies was really struggling with his country. I happen to mention it to my dad. My dad printed off everything we had on that country and had me take it to school for him. I knew my bully wouldn't take anything from me. So when he was across the room talking to a friend, I left it on his desk. He screamed at me for putting something on his desk until he realized what it was. He stopped bullying me for a whole week after that.

After word got around I had a couple other kids approach me asking for information on their countries.
The whole thing was a nightmare! And the school didn't learn their lesson. The project continued for at least three more years. Every year parents were dreading their kids entering the 7th grade.
