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.
Modeling Limits to Cell Size
Source Institutions
This investigation provides learners with a hands-on activity that simulates the changing relationship of surface areas-to-volume for a growing cell.
Life Size: What's in a microbe?
Source Institutions
In this activity on page 3 of the PDF, learners visualize the relative size and structural differences between microbes that have the potential to cause disease.
Small Snails, Enormous Elephants
Source Institutions
This activity (located on page 2 of PDF) introduces learners to the real size of animals using nonstandard measurement.
Supersize That Dinosaur
Source Institutions
In this activity, learners explore the size and scale of dinosaurs. Learners listen to "The Littlest Dinosaurs" by Bernard Most. Then, learners estimate the size of a Triceratops and T.
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.
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.
Tomb Mapping
Source Institutions
In this activity, learners examine the culture and history of the tomb site.
Looking Back Through Time
Source Institutions
In this activity, learners create their own archaeological profiles.
Life Size: Line 'em up!
Source Institutions
In this activity on page 1 of the PDF, learners compare the relative sizes of biological objects (like DNA and bacteria) that can't be seen by the naked eye.
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).
Size, Scale and Models
Source Institutions
In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.
Heavy or Light
Source Institutions
In this activity, learners explore a scale by comparing objects, which look similar but have different weights. Learners predict and then measure the weights of various objects using a scale.
How Big Were the Dinosaurs?
Source Institutions
In this activity (located on page 4 of PDF), learners gain insight into the actual size of dinosaurs and practice making estimations and measurements.
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.
Compare Dinosaur Body Parts
Source Institutions
In this activity, learners explore the size and scale of dinosaurs. Learners listen to "The Littlest Dinosaurs" by Bernard Most to learn about the different sizes of dinosaurs.
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).
Horton Senses Something Small
Source Institutions
In this story time program, young learners listen to the Dr.
Comparing Sizes of Microorganisms
Source Institutions
In this activity related to microbes, learners create scale models of microorganisms and compare relative sizes of common bacteria, viruses, fungi and protozoa using metric measures: meters, centimete
