  Can you imagine clothing, handbags, or shoes made from seaweed or spider silk? To become more sustainable, the textile industry is looking for ways to develop more eco-friendly fabrics. Biofabrics derived from living organisms such as seaweed or bacteria have been proposed as a potential alternative to conventional fibers. In this science project, you will make several biofabrics from alginate (seaweed) and conduct tests to find out which one is...

Textiles or fabrics are a diverse group of materials, and they are not only used to make clothing. They are also used to make furniture, medical equipment, bags, sports gear, the interior of cars, and much more. For this reason, the textile industry is a significant contributor to the global economy. One role of scientists and engineers in an industry like textiles is to evaluate the environmental impacts of the products they make and figure out...

Objective Build a device that lets you use voice commands to control one or more household appliances. Introduction Traditionally, most lights and household appliances have been controlled by manual switches and buttons. Today, though, many newer devices connect to the Internet, and they can be controlled from your phone or computer. These Internet-connected devices, sometimes called smart home devices, are part of the Internet of things (IoT), a network of devices other than traditional computers...

  Google Classroom Introduction Have you ever wondered why biological siblings look so much alike? Why do they often share physical traits, such as hair color or eye color? It all has to do with their genes. Genes are passed on from parents to their offspring. This means that you share some of the same genes with your biological parents and siblings! In this activity, you will use an alien model to demonstrate...

IntroductionMathematicians look at the world around them in terms of numbers and formulas, and now, you can discover the formula for Pi too! In this science activity you will examine circular objects and see what you can discover about their sizes. As you explore, you might be surprised at how useful the results can be—maybe it will inspire you to save up for a bike with bigger wheels! Materials At least...
