Minnie and Conor interview Climate Week chief executive Kevin Steele in the room where The King's Speech was filmed
Four students from The Charter School in London were present at the launch of Climate Week at Lancaster House.
They conducted some interviews and took in the surroundings before finding out that big names had been there before them.
Two Year 7 pupils were accompanied by two students from Year 11 who filmed them conducting their interviews.
Minnie, 12, said: "We interviewed Ross Harrison, who was nominated for the most inspirational young person award.
"He is at university and spent a year looking at climate change and making a 40-minute documentary called Beyond the Brink about climate change and wildlife and how it is affecting us and everyone.
"Then we saw the actual award ceremony. There were lots of different categories including the best community initiative, which was powering an area with water, and the best educational initiative.
"This was a climate change schools project where they went to lots of different schools in the north-east and talked to children from primary schools to colleges about how to make schools more eco-friendly."
Ross Harrison did not win the award he was nominated for, as Minnie explains.
"Ellie Hopkins won it," Minnie said. "She is 22 and she did lots of campaigns and raised lots of money UK-wide. At the moment she is working with the team preparing the Olympics about the sustainable side of the Games."
Minnie's classmate Conor, also aged 12, was also involved in preparing and conducting the interviews.
"The best thing was interviewing people," he said. "We had researched them and wrote questions that were appropriate for them and they were the right type of questions.
"Lancaster House was very posh and had gold on the walls. Ross was the best person we interviewed as we had planned him the best.
"School Report has been very exciting and very different to what we usually do.
"What I have enjoyed most has been talking to people you don't usually get to talk to."
One of the high spots of the day for film fan Minnie was when she realised where she had seen the interior of Lancaster House before.
"We did our interviews in the room where Colin Firth walked down the corridor in The King's Speech," she said.
"It was where he sees lots of people nodding and all wishing him good luck before he goes into the little room to make his speech.
"I didn't realise where we were until I saw lots of people were looking around.
"It was a mega film and being there was really exciting because I like lots of actors in the film."
Teacher Ms Proctor accompanied the children on the trip and said: "The success of the interviews depended on the pupils having done research, which they did.
"But one of the interviews was one they weren't expecting with Kevin Steele, chief executive organiser of Climate Week, and that made them realise just how difficult it is to do interviews without any preparation."
