Writing for Night Vision
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Forensics), learners will use a home video camera with a “night vision” mode to test how various inks appear outside the spectrum of visibl
Concentrate: Concentrations and Reaction Rates
Source Institutions
Visitors incrementally increase the amount of iodate in three different test tubes containing the same amount of a starch solution.
Glitter Slime
Source Institutions
Our bodies defend themselves in many different ways to prevent us from getting sick.
Doppler Effect
Source Institutions
Sound changes pitch relative to how you or the source of the sound is moving. Use this simple activity developed by the Exploratorium to experience the Doppler Effect yourself!
Sound Off!
Source Institutions
This activity includes several games about animal sounds. Using their sense of hearing and communicating with various kinds of noisemakers, learners role-play predator and prey.
The Rain Man
Source Institutions
In this activity, learners observe the hydrologic cycle in action as water evaporates and condenses to form rain right before their eyes.
3D-tection: Trying to Fit In
