Britain's Queen Elizabeth was given a science lesson as she toured Lister Community School.
The 89-year-old royal popped into the school in Plaistow, east London and watched as students neutralised an alkaline with an acid during one of the lessons before being treated to a performance by the National Youth Orchestra, an organisation helped by the Queen's Trust.
Sir Trevor McDonald, who is a trustee of the fund, said: "This trust had some money to give to causes and I had a view on some of the causes.
"This school is an example of that benefit, grants are not directly given to the school but a number of organisations associated with the school."
Meanwhile, during her visit, the Queen unveiled a plaque and also signed the visitors' book.
One student said: "I was excited and nervous when she came in. We talked about the opportunities at IntoUniversity and what we are studying."
However, before the Queen's visit, most of the children were sceptical about her arrival.
The school's assistant headteacher Simon Beck added to the Newham Recorder newspaper: "Some of the students said, 'We'll believe you when we see her'. I think they believe us now."
