Dripping Wet or Dry as a Bone?
Learners investigate the concept of humidity by using a dry and wet sponge as a model. They determine a model for 100% humidity, a sponge saturated with water.
Batter Up!
Source Institutions
This activity (on page 3 of the PDF under GPS: Baseball Activity) is a full inquiry investigation into how "bounciness" relates to the distance a ball will fly when hit off a batting tee.
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.
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.
Rate It: Working With Zero and Negative Numbers
Source Institutions
In this activity, learners will rate the day, a book, or something else on a scale from -2 to 2. This activity works well for groups of all ages.
Measuring Rules
Source Institutions
In this math activity, learners create their own units of measurement by making noodle rulers. Learners practice estimating and measuring objects using the noodle rulers .
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.
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.
Twenty Guesses: Information Theory
Source Institutions
This activity introduces the idea that computer scientists measure information by how "surprising" a message is.
Stacking Dice
Source Institutions
In this math game, learners try to earn the most points by winning stacks of four dice. Learners practice number recognition and addition skills.
Surface Area and Soda Geysers
Source Institutions
This is an activity (located on page 4 of the PDF under Surface Area Activity) about surface area and reactivity.
Now or Later: The "Recency/Primary" Effect
Source Institutions
In this activity (18th on the page), learners conduct an experiment to examine memory.
Polynomial and Rational Functions: Building Boxes
Source Institutions
In this math lesson, learners explore polynomial and rational function patterns.
Pace-Off!
Source Institutions
In this math activity, learners use non-standard measurement (paces) to find the distance from one point to another. Learners practice estimating and measuring distances .
Space Weather Action Center
Source Institutions
In this interdisciplinary activity, learners create a Space Weather Action Center (SWAC) to monitor solar storms and develop real SWAC news reports.
A Cubic Foot Per Second
Source Institutions
In this activity, learners measure and calculate the amount of cubic feet various containers contain. Next, learners investigate cubic feet per second (cps), by carrying jugs in one second.
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.
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.
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.
