THE EQUINOX AT PARQUE DAS NAÇÕES

  

  

"It was really handy winning the sundial because my grandmother had lost her watch and I had taken the battery out of the kitchen clock to put in a toy so I made the sundial for her to know what time it was."

André Machado, Esc 1º CEB nº 7 de Setúbal

At 11 o’clock on March 22nd near the Pavilhão do Conhecimento in Parque das Nações in Lisbon, an experiment was carried out to determine latitude by measuring the height of the sun. Basic and secondary school students were also able to tell the time of the midday sun by observing the changes in the length of a shadow.
