Fizzy Nano Challenge
Source Institutions
This lesson focuses on how materials behave differently as their surface area increases.
Skin, Scales and Skulls
Source Institutions
In this activity, learners examine body parts (including skin, scales, and skulls) from fish, mammals and reptiles. Questions are provided to help encourage learner investigations.
Incredible Shrinking Shapes
Source Institutions
In this activity, learners get hands-on experience with ratios and scaling while making their own jewelry out of recycled plastic containers.
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.
Exploring at the Nanoscale
Source Institutions
This lesson focuses on how nanotechnology has impacted our society and how engineers have learned to explore the world at the nanoscale.
Plankton Feeding
Source Institutions
This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.
Earth Walk
Source Institutions
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
Gummy Growth
Source Institutions
In this activity related to Archimedes' Principle, learners use water displacement to compare the volume of an expanded gummy bear with a gummy bear in its original condition.
Cylinders and Scale
Source Institutions
In this activity, learners investigate the relative growth of lengths, areas, and volumes as cylinders are scaled up.
Gecko Feet
Source Institutions
This is an activity (located on page 3 of PDF under Gecko Feet Activity) about modeling a nanoscale phenomenon (gravity-defying gecko feet) with macroscale objects (shoes).
What is a Nanometer?
Source Institutions
This lesson focuses on how to measure at the nanoscale and provides learners with an understanding how small a nanometer really is.
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.
Make a Human Scale Ladder
Source Institutions
In this quick activity about size and scale (on page 2 of the PDF under What's Nano?
Pea Brain!: Explorations in Estimation
Source Institutions
In this activity, learners use two different techniques to estimate how many little things fit into one bigger thing.
Exploring Size: StretchAbility
Source Institutions
In this game, learners explore the different sizes of things in the world. In this Twister-like game, learners must place a hand or foot on a circle of the right scale - macro, micro, or nano.
Spring Scale Engineering
Source Institutions
In this activity, learners explore how spring scales work and how they are used for non-exact weight measurement.
