Our measurement challenges are a chance for everyone to have some fun and learn about the science of measurement. How heavy, how long, how fast, how bright....? All these measurements will be investigated and you will find out why measurement matters in our everyday lives.
This is your chance to be curious, take some measurements and compare your results. Join in, have fun and learn some real practical science!
Follow us on social media and share pictures of your tests using the hashtag #MeasurementAtHome.
These challenges are created to support purposeful and varied practical science as recommended by the Gatsby Charitable Foundation and are led by Outreach Manager, Andrew Hanson MBE.
If you would like to suggest experiments we can include, please get in touch.
All our Measurement at home challenges are listed below
How much variation is there in how long containers keep drinks warm for? How much effect does a lid have? Do drinks take the same time to cool from 60 to 50 °C as from 50 to 40 °C? What does this experiment have to do with reducing the impact of heating houses upon climate change?
Does ice melt fastest on land, in fresh water, or in salty water? You may be amazed with your results and observations. This challenge links to what can happen as glaciers and polar icecaps melt.
This challenge will ask the question: can you trust a teaspoon to give you the right dose of medicine? It will also explain how increased numbers of measurements increase precision.
Is your dominant hand faster or slower to react? Does age affect reaction time? What is gravity? Find out with our Reaction time challenge.
How powerful is a candle? Is the total power (light plus heat) of a candle more or less than for a typical domestic LED lightbulb?
What is meant by ‘energy efficient lighting’?
How much can vegetables ‘grow’ in 90 minutes? Do all vegetables change size by the same amount through osmosis and how does water salinity affect change in vegetable size?
Is GPS better indoors or outdoors? How accurate is GPS? What is the difference between accuracy, resolution and precision? Find out how good your Global Positioning System (GPS) is?
Can you make a 1 second pendulum? What is the length of a 1 second pendulum? Find out what is the best thing to make a bob from and why are some pendulums better than others.
What is your tap water temperature? Can you use dissolving sugar to measure tap water temperature? Find out why tap water is at the temperature it is.
Are you taller or wider? Was an ancient Roman architect right about human proportions? If you measure more than once, do you get the same value and how much taller are you after lying down for 15 minutes?
Can you fly a piece of A4 paper exactly 3 metres? Can you design and build equipment to make this happen? Can you repeat this challenge three times? Learn how you can.
How fast does sound travel? Can you measure the speed of sound? NPL uses this technique to measure temperature very accurately
How does temperature affect bounciness? After a night in the freezer, will balls bounce more or less? This test uses the metre, which NPL measures very accurately.
Can you dream up a new measurement unit? Metres, seconds, newtons, amps are examples of units that we all use to measure things.
How strong are your breakfast cereal flakes? How do you think cereal type and flake width affects break point? This experiment finds the break point of cereal flakes.
