The Geophysical Light/Dark Cycle
Source Institutions
This is an activity (located on page 131 of the PDF) related to sleep and circadian rhythms as well as space travel.

Patterns and Relationships: Here, There & Everywhere
Source Institutions
In this math activity, learners use a variety of sensory modalities to gain experiences with identifying, describing and creating repeating patterns.

Tiny Tubes
Source Institutions
In this activity, learners make "totally tubular" forms of carbon. Learners use chicken wire to build macro models of carbon nanotubes.

Avalanche
Source Institutions
In this geology activity, learners create a model using a mixture of salt and sand inside a CD case. When the case is tilted or inverted, the mixture dramatically sorts into a layered pattern.

Geometry and Spatial Relations: Sidewalk Capers
Source Institutions
In this math lesson, learners use a variety of manipulatives to explore spatial relationships of squares and their transformations.

Measuring Your Breathing Frequency at Rest
Source Institutions
In this activity about the brain and sleep (on page 138 of the PDF), learners measure their resting breathing rates. Learners will discover that breathing frequencies vary amongst individuals.
Stories in the Sky
Source Institutions
In this activity, learners create their own constellations and star patterns and write a short, descriptive story explaining the significance of their star pattern/constellation.

CD Spinner
Source Institutions
In this activity, learners create a simple “top” from a CD, marble and bottle cap, and use it as a spinning platform for a variety of illusion-generating patterns.

Two Washers
Source Institutions
In this activity, learners create a mind and math puzzle that requires a three-dimensional solution.

Paths and Ponds
Source Institutions
In this activity, learners use squares to figure out how many border tiles are needed to enclose different areas.

Beaded Braids: Investigating Patterns & Ratios
Source Institutions
In this activity learners create patterns of hair beads.

Twenty Guesses: Information Theory
Source Institutions
This activity introduces the idea that computer scientists measure information by how "surprising" a message is.

Inverse Functions: Pennies, Pressure, Temperature, and Light
Source Institutions
The major goal of this math lesson is to have learners collect data from a variety of experiments, determine what models best fits their data, and explain why their models are best.

Measure the Speed of a Water Leak
Source Institutions
In this activity (page 2 of PDF under GPS: Glaciers Activity), learners will measure the rate at which water streams out of a leaky cup.

Twisted Tesselations
Source Institutions
In this activity (on pages 41-47 of PDF), learners explore tesselating geometric patterns (repeated shapes, similar to the art of M.C. Escher).

Linear Functions: Mystery Liquids
Source Institutions
In this math lesson, learners analyze the density of liquids in order to explore linear functions.
What's the Difference?
Source Institutions
In this sorting activity, learners play a game in which they try to identify the largest number of differences between two objects.

Polynomial and Rational Functions: Building Boxes
Source Institutions
In this math lesson, learners explore polynomial and rational function patterns.

Patterns and Relationships: Peddling Petals
Source Institutions
In this math lesson, learners use the setting of a flower-making fundraiser to explore a variety of patterns. Learners examine the patterns in a flower design made of triangles surrounding a square.

How Quick Are Your Responses?
Source Institutions
In this activity (on page 134 of the PDF), learners explore reaction time.
