I learnt that all world time is calculated from the prime meridian, an imaginary line at the Royal Observatory in Greenwich, London. I learnt that the Royal Observatory was set up in 1675 because sailors needed to know the exact time to navigate around the world. I also leant that the meridian divides the globe into two hemispheres.

The NEMO Science Museum in Amsterdam is situated on top of the River Ij car tunnel and it’s a fantastic ‘hands-on’ science and technology museum that is very popular with both children and adults. The remarkable museum, which is built in the shape of a green ship’s hull, was designed by the famous Italian architect Renzo Piano and opened in 1997. There are many interesting exhibits spread out over 4 ‘decks’ covering areas such as DNA, electricity, the human brain, computers and the origins of life. In addition, visitors can watch entertaining shows and demonstrations. In the summer it’s even possible to climb up to the roof deck cafe and relax in a deckchair!
