pH Scale
Source Institutions
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.

Does Size Make a Difference?
Source Institutions
In this activity on page 15 of the PDF, discover how materials and physical forces behave differently at the nanoscale.

Exploring Forces: Gravity
Source Institutions
In this nanoscience activity, learners discover that it's easy to pour water out of a regular-sized cup, but not out of a miniature cup.

Sniffing for a Billionth
Source Institutions
This is an activity (located on page 4 of the PDF under What's Nano? Activity) about size and scale.

Gravity Fail
Source Institutions
In this activity, learners try pouring water out of a regular cup and a miniature cup. It’s harder than it sounds! Learners discover that different forces dominate at different size scales.

Try Your Hand at Nano
Source Institutions
This lesson focuses on two simple activities that younger learners can do to gain an appreciation of nanotechnology. First, learners measure their hands in nanometers.

Shrinking Cups
Source Institutions
This is a quick activity (on page 2 of the PDF under Gecko Feet Activity) about the forces of gravity and surface tension and how their behavior is influenced by size.

Exploring Size: Scented Solutions
Source Institutions
This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).

Sugar Crystal Challenge
Source Institutions
This lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness.

Cabbage Juice Indicator
Source Institutions
In this chemistry activity, learners make indicator solution from red cabbage. Then, learners test everyday foods and household substances using the cabbage juice indicator.

Avogadro's Bubbly Adventure
Source Institutions
In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.

Fizzy Nano Challenge
Source Institutions
This lesson focuses on how materials behave differently as their surface area increases.

Demonstrating An Epidemic
Source Institutions
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

Human Impact on Estuaries: A Terrible Spill in Grand Bay
Source Institutions
In this activity, learners make a model of a pollution spill that occurred at Bangs Lake in Mississippi and measure water quality parameters in their model.
