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.
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.
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.
Battleships: Searching Algorithms
Source Institutions
This activity explores the main algorithms that are used as the basis for searching on computers, using different variations on the game of battleships.
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.
Walking Polygons
Source Institutions
In this activity, learners walk the sides and interior angles of various polygons drawn on the playground. As they do so, learners practice rotating clockwise 180° and 360°.
Plot the Dot: A Graphical Approach to Density
Source Institutions
In this activity, learners work in groups to determine the mass and volume of four samples: glass marbles, steel washers or nuts, pieces of pine wood, and pieces of PVC pipe.
Plugged in to CO2
Source Institutions
In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.
Linear Functions: Mystery Liquids
Source Institutions
In this math lesson, learners analyze the density of liquids in order to explore linear functions.
Polynomial and Rational Functions: Building Boxes
Source Institutions
In this math lesson, learners explore polynomial and rational function patterns.
Secret Codon
Source Institutions
In this activity, "write" a secret message in genetic code as beads on a string.
Whose Fault Is It?
Source Institutions
In this seismic simulation, learners play a "who-dunnit" game to explore earthquakes.
Arctic Sea Ice
Source Institutions
In this activity, learners explore how the area of Arctic sea ice has changed over recent years. First, learners graph the area of Arctic sea ice over time from 1979 to 2007.
How Big is Small
Source Institutions
In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.
Parabola Basketball
Source Institutions
In this activity, learners build mini-basketball courts and explore the laws of physics. Learners discover that everything you throw or shoot on earth travels in a parabola.
Measuring Your Blind Spot
Source Institutions
In this activity, learners calculate the width (horizontal diameter) of the blind spot on their retina. Learners make a blind spot tester using a piece of notebook paper.
Having a Gas with Cola
Source Institutions
In this activity, learners measure the amount of carbon dioxide in a carbonated drink.
Ship the Chip
Source Institutions
In this activity, learners explore engineering package designs that meet the needs of safely shipping a product.
Pi Graph
Source Institutions
In this activity, learners use a straight line to learn about circles. Learners measure and record the diameter and circumference of different sized cylindrical objects on a chart.
