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.
Public Key Encryption: Kid Krypto
Source Institutions
In this activity, learners conduct a simulation exercise related to public key encryption and try to intercept a message sent between two learners.
Mercury in the Environment
Source Institutions
In this environmental science lesson, learners will examine the dangers of mercury and how humans contribute to growing mercury emissions on Earth.
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.
Hold a Hill
Source Institutions
In this outdoor activity, learners investigate the relationship between the slope of a trail and soil erosion.
Our Sense of Sight: Color Vision
Source Institutions
In this activity, learners investigate color vision as well as plan and conduct their own experiments.
Quadraphonic Wind
Source Institutions
In this activity, learners discover how the extent of various wind speeds changes in each of the four quadrants around a hurricane.
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.
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.
How Quick Are Your Responses?
Source Institutions
In this activity (on page 134 of the PDF), learners explore reaction time.
Whose Fault Is It?
Source Institutions
In this seismic simulation, learners play a "who-dunnit" game to explore earthquakes.
Graph Dance
Source Institutions
In this activity, learners "dance" (move back and forth at varying speeds) by reading a graph. This is a kinesthetic way to help learners interpret and understand how motion is graphed.
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.
Let's Count Humpback Whales: Environmental Effects on Population
Source Institutions
In this activity, learners use whale count data from the Hawaiian Islands Humpback Whale National Marine Sanctuary to compare whale counts in relation to environmental factors.
The Scoop on Scallops
Source Institutions
In this data analysis activity, learners quantify the abundance and distribution of sea scallops in and adjacent to the Mid-Atlantic closed areas.
The Poor Cartographer: Graph Coloring
Source Institutions
In this activity, learners help a poor cartographer color in the countries on a map, making sure each country is colored a different color than any of its neighbors.
Understanding Albedo
Source Institutions
In this activity related to climate change, learners examine albedo and the ice albedo feedback effect as it relates to snow, ice, and the likely results of reduced snow and ice cover on global temper
Mapping Sea Level Rise
Source Institutions
In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.
