This lesson focuses on how nanotechnology has impacted our society and how engineers have learned to explore the world at the nanoscale.

In this activity, learners investigate Scanning Probe Microscopes (SPM) and then work in teams using a pencil to explore and identify the shape of objects they cannot see, just as SPMs do at the nano

In this activity, learners explore the engineering behind seismographs and how technology has improved accurate recording of earthquakes.

In this experiment, learners design and build a model room in a shoebox and furnish it with tiny furniture.

In this water pollution activity, learners create pond water cultures and investigate the effects of adding chemicals or natural nutrients.

Water treatment on a large scale enables the supply of clean drinking water to communities.
