Dye Detective
Oregon Museum of Science and IndustryAdd to list DetailsLearners analyze mixtures of dyes using filter paper chromatography. They place spots of the different dyes at the bottom of a piece of filter paper, and hang the paper to touch the surface of...
Dyeing Wool with Fungi
Biotechnology and Biological Sciences Research CouncilAdd to list DetailsIn this activity (p.23 of PDF), learners dye wool with fungi. Learners discover that natural chemicals in fungi can dye wool different colors. Note: Natural dyeing normally requires a color...
Kool Colors
Oregon Museum of Science and IndustryAdd to list DetailsLearners investigate how temperature affects the rate of chemical reactions by observing how steel wool reacts with various types of Kool-Aid solutions at different temperatures. The reaction is...
To Dye For
Oregon Museum of Science and IndustryAdd to list DetailsLearners add two dyes to mineral oil and water, and then compare their miscibility (how well they mix) in each. Learners discover that the molecular structure of a dye determines whether it will...
Luminescence
Mount Holyoke CollegeAdd to list DetailsIn this two-part activity about luminescence, learners explore the chemistry that happens inside glow sticks and other light producing reactions. First, learners build a ground state model and a...
Dye Like A Natural
The ExploratoriumAdd to list DetailsIn this activity, learners stain fabrics--on purpose! Learners explore the art of natural dyeing by using dyes and substrates that are both derived from plant or animal sources as well as mordant...
African Arts
University of Nebraska State MuseumAdd to list DetailsIn this two-day activity (on pages 16-22), learners use a process like that of the Yoruba people of Nigeria to create an African symbol on cloth. Learners first make cassava gel, then paint...
Water Breathers
Lawrence Hall of ScienceAdd to list DetailsIn this activity and/or field trip, learners investigate the water currents that aquatic animals create when they breathe, feed, and propel themselves through water. Learners trace the currents in...
Gel Electrophoresis of Dyes
APSnetAdd to list DetailsIn this experiment related to plant biotechnology, learners discover how to prepare and load an electrophoresis gel. They will then run the gels in an electrophoresis system to separate several...
Writing for Night Vision
Twin Cities Public TelevisionAdd to list DetailsIn 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...
