Family Day: Exploring Measurement

Our free family fun day on Saturday 18 May explored the physics of measurement. The event was hosted in partnership with the National Physical Laboratory

Our Free Family Day at our home in King's Cross, London, included mini-games, hands-on demonstrations and craft activities, all about how we measure things.

Children discovered the answers to questions such as:

  • How long does a second last?
  • How did we decide the length of a metre?
  • What is the difference between dark and light?

They also went on a discovery trail around our new home.

Activities were suitable for children aged 5-11 but there was plenty for the whole family to enjoy. Free snacks and refreshments were available throughout the day.

Our Family Days are part of a programme of events to make physics available to all. This event follows on from our first Family Day which took place in February, attended by 450 people. 

Why are we exploring measurement?

Metrology is the science of measuring things - but did you know that some of the ways in which we measure the world around us are changing?

Our family day event celebrated World Metrology Day, which takes place every year in May. This year, the day was all about the International System of Units (SI) and the changes to some of the definitions of these units of measurement.
