In this online interactive simulation, learners will test the pH of liquids like coffee, spit, and soap to determine whether each is acidic, basic, or neutral.

In this hands-on and feet-on excursion, learners take a science walk to visualize the planet's immense size and numerous structures, without the usual scale and ratio dimensions found in most textbook

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 group activity, learners will mark important developments of life on Earth on a timeline (each foot in length representing 200 million years).

In this math-based activity, learners model the intensity of light at various distances from a light source, and understand how astronomers measure the amount of sunlight that hits our planet and othe

In this activity, learners create their own archaeological profiles.

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

In this quick activity about predicting (located on page 2 of the PDF under Where's Nano?

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

This experiment allows learners to experience a small scale "epidemic," demonstrating the ease with which disease organisms are spread, and enables learners to determine the originator of the "epidemi

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