Dye Eggs Using Silk Ties for Egg-cellent Colors

Science Fair Project Idea

Scientific Method

Have you ever dyed eggs? Turning eggshells from white into different, dazzling colors can be a lot of fun! To do this, most people buy dye tablets to make different colors in a liquid bath. They then dip the egg into the liquid and wait till it turns the desired color. You can dye eggs in many other ways, and one neat method uses silk ties. Sounds strange to use clothing to dye eggs, right? But it actually works really well! In this science project, you will dye eggs with old or used… Read more

Engineering Silver Nanoparticles

Lesson Plan Grade: 9th-12th

Engineering silver nanoparticles for use in water filters has shown promising results in keeping water free of disinfection byproducts that arise after chlorination. In this activity, the students do individual research to learn about nanotechnology and silver nanoparticles, and how silver nanoparticles can be used in water treatment. Students choose a plant of their choice (from home, school, or from the teacher) to use as an agent to reduce silver nitrate into silver… Read more

Fabulous Fabrics: The Chemistry of "Green" Textiles

Lesson Plan Grade: 6th-8th

Look around and you will see fabrics everywhere, from clothes to upholstery, in a wide range of colors. In this chemistry lab students will dye strips of fabrics to explore how variables like pH and fiber type influence fabric colors. Students will also look at the life cycles of natural and synthetic fibers and apply green chemistry principles to understand how science can help make advances towards a "greener" textile industry. Learning Objectives Students will: Understand that synthetic… Read more

Have you ever wondered how sweating helps keep you cool on a hot summer day? Sweat, which is mostly water, cools us down when it evaporates. When water evaporates, it changes from a liquid to a gas. The gas carries away heat with it, helping to remove heat from your skin. Not only can evaporation cool down your body, it can also cool down other things, such as chocolate. Heat on a hot summer day can turn your solid candy bar into a gooey, melted mess, but how well can evaporation keep your… Read more
