Not only do future engineers learn the difference between accuracy and precision, they also get some hands-on experience using different measuring tools. 

Teach the masses about the metric system with this hands-on measurement lesson. Given a fruit or vegetable, learners estimate, measure, and convert its mass using the metric units gram and kilogram.

How big is that carrot? Why one hand span, of course. As an exercise in measurement, individuals trace their hand in their science journal and search the school garden for one object the same size as the span between their thumb and...

Conversion immersion — it's measuring mania! A set of four activities teaches scholars to convert between customary and metric units. Resource covers unit conversions in length, temperature, weight/mass, and volume.

Isn't technology great? The 12th installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program introduces technology that marine scientists use. Pupils take part in an activity using conductivity,...

Break out those math manipulatives, it's time to teach about area! Capturing the engagement of young mathematicians, this three-instructional activity series supports children with learning how to measure the area of squares,...
