Where is the Sun?
Source Institutions
In this activity, learners verify that the Sun appears in a different location at a specific time every day of the year with one exception: on the Equinoxes.
Hot Stuff!: Investigation #4
Learners test two jars containing soil, one covered and one open, for changes in temperature. After placing the jars in the Sun, learners discover that the covered jar cools down more slowly.
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.
Rusty Penny
Source Institutions
In this easy chemistry activity, learners submerge pennies in different liquids (water, lemon juice, vinegar, liquid hand soap, salt water, and baking soda mixed with water) to observe which best clea
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.
Meteoroids and the Craters They Make
Source Institutions
In this activity, learners investigate the formation of craters. Learners will examine how the size, angle and speed of a meteorite's impact affects the properties of craters.
Hot Stuff!: Investigation #1
Learners test two jars, one containing plain air and one containing carbon dioxide gas, to see their reactions to temperature changes.
Right Foot/Left Foot
Source Institutions
In this activity (2nd on the page), learners conduct a series of tests to find out which foot is more dominant. In other words, are they right-footed or left-footed?
What Do Birds Do?
Source Institutions
This activity (located on page 3 of the PDF under GPS: Cave Swallows Activity) is a full inquiry investigation into bird behaviors.
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.
From the Internet to Outer Space
Source Institutions
In this activity, learners will use Google Sky to observe features of the night sky and share their observations.
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.
How Much Water is in that Cloud?
Source Institutions
In this activity, learners working in pairs saturate a cotton ball using water drops from an eyedropper to demonstrate the high water capacity of clouds.
Start a Rock Collection
Source Institutions
Learners follow a three-step process to start their own rock collection.
Glaciers
Source Institutions
In this online activity, learners adjust mountain snowfall and temperature to see how glaciers grow and shrink. They will use scientific tools to measure thickness, velocity and glacial budget.
Right Hand/Left Hand
Source Institutions
In this activity (1st on the page), learners conduct a series of tests to find out which of their hands is more dominant. In other words, are they right-handed or left-handed?
Mineral Scavenger Hunt
Source Institutions
In this activity, learners participate in a scavenger hunt, searching for and recognizing minerals and products that contain minerals.
Drying It Out
Source Institutions
In this activity, learners investigate and compare the rate of drying in different conditions.
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.
