Making a One-Second Timer
Source Institutions
This lab activity has learners create a pendulum with a one-second period.
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.
The Electric Squeeze
Source Institutions
In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.
Illuminations on Rates of Reactions
Source Institutions
In this activity, learners investigate the speed of chemical reactions with light sticks. Learners discover that reactions can be sped up or slowed down due to temperature changes.
Introduction to the New Chain Gang
Source Institutions
In this activity, learners use pop-beads to understand the characteristics and properties of polymer chains.
Fireworks!
Source Institutions
In this chemistry lab activity, learners model the colors of fireworks by burning metallic solutions in a flame and observing the different colors produced.
Light Quest
Source Institutions
Learners test their "light-smarts" by playing a game called "Light Quest!" The game board represents an atom and each player represents an electron that has been bumped into the atom's outer unstable
Exploring the Nanoworld with LEGO Bricks: Probing the Structure of Materials at the Nanoscale
Source Institutions
In this activity (pages 17-31), learners are introduced to techniques that are used to determine the structures of solid materials.
Sea State: Forecast Conditions at Sea
Source Institutions
In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.
Black Magic (Color Chromatography)
Source Institutions
With a coffee filter, a black marker, and a cup of water, discover the secret colors hidden in black ink.
Spectroscope
Source Institutions
In this activity (posted on March 12, 2011), learners follow the steps to construct a spectroscope, a tool used to analyze light and color.
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
Glow Up
Source Institutions
In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.
Convection Current
Source Institutions
In this activity, learners make their own heat waves in an aquarium.
Why is the Sky Blue?
Source Institutions
In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.
Column Chromatography
Source Institutions
In this activity, learners separate the components of Gatorade using a home-made affinity column.
Hot Air
Source Institutions
In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.
Radiohead
Source Institutions
When you teeth clatter, they make quite the racket disproportionately to how much they actually sound to someone else.
Conversation Piece
Source Institutions
Focus sound through a balloon! In this Exploratorium activity, you'll use dry ice to create a balloon that's a sound lens.
Nuclear Fusion
Source Institutions
This simple and engaging astronomy activity explains nuclear fusion and how radiation is generated by stars, using marshmallows as a model.
