World's Oldest Calendar Discovered in U.K. – NATIONAL GEOGRAPHIC
Archaeologists working in Scotland have uncovered what they believe to be the world's oldest lunar calendar—a series of 12 large, specially shaped pits that were designed to mimic the various phases of the moon. The pits aligned perfectly on the midwinter solstice in a way that would have helped the hunter-gathers of Mesolithic Britain keep accurate track of the passage of the seasons and the lunar cycle. At nearly 10,000 years old, these curious lunar-cycle-marking pits in Aberdeenshire

Measuring gases using eddy covariance — SLH T&L RESOURCE
Measurement is an integral part of science. As technology progresses, so does the range and accuracy of what we can measure. Where once we made measurements using only our senses, University of Waikato scientists have a device that measures greenhouse gases 10 times per second and to concentrations of about 0.2 parts per billion! These advances are game changers, according to Associate Prof. Dave Campbell and Prof. Louis Schipper. For more than two decades, Dave and Louis have been using…
MSL LEGO Kibble balance
Dr Rebecca Hawke and Dr Yin Hsien Fung are research scientists at the Measurement Standards Laboratory (MSL). MSL is building the southern hemisphere’s only Kibble balance – an exceptionally accurate weighing machine. Rebecca and Fung explain how the simpler yet similar LEGO version of the Kibble balance works.
Measurement Standards Laboratory (MSL) — SLH RESOURCE
The Measurement Standards Laboratory (MSL) is New Zealand’s national metrology institute. Its role is to ensure that New Zealand’s units of measurement are consistent with the International System of Units, the SI. MSL is a vital facility that enables New Zealand to communicate technically and scientifically with the rest of the industrialised world.
New MSL Laboratory
ONE-OF-A-KIND BUILDING FOR THE MEASUREMENT STANDARDS LABORATORY (MSL) OF NEW ZEALAND. The simple exterior of the new building for the MSL hides a complex design and a technologically advanced laboratory. For MSL Director Fleur Francois, the building represents a significant investment in the provision of national measurement standards to NZ. “The new building will deliver the incredibly precise environment we need to propel our technical capabilities forward,” says Fleur. ...
Building a lego marble run — THE EDUCATION HUB
What to do Challenge your child to build a marble run on the baseboard using bricks as the walls of the run. Simply tilt the baseboard to guide the marble through the run. Support younger children by starting them off, and ask them questions like “How will you know how wide to make your walls?... What learning does this activity promote? measurement, mathematics, design, engineering, problem-solving, creativity and imagination
Measurements Are Often Full of Lies—and That's OK
Does a balance measure mass or weight? This common question reveals a core confusion about lab instruments: It's not always obvious what they measure.
To measure the quantity of anything, we need a comparison with some precise unit value. Early humans used body parts and natural surroundings to provide suitable measuring instruments.
Wharenui is the Māori word meaning ‘big house’. This diagram of a wharenui shows the key parts of the whare. Careful measurement of each component was needed in the construction of the whare.
Terabytes, Gigabytes, & Petabytes: How Big Are They?
How big is a terabyte? How many GB in a TB? How many megabytes in a gigabyte? What's a petabyte? As crazy as it all sounds, it's easy to understand.
