Fabric is a technology that every one of us encounters on a daily basis. Whether it's part of the clothes we wear, or the furniture we sit on, fabric has unique properties depending on the purpose for which it is used. Kindergartners will be exploring many types of fabric, learning key vocabulary that can describe the properties of not just fabric, but many other materials engineers use to develop the technologies we all use.
Now that Kindergartners have mastered many new properties to describe fabric, they're moving on to learn properties that describe other types of materials, too. Our next focus will be on how each material allows light to pass through it. Materials that let light completely through them are considered transparent. This allows us to see on the other side of the material. Materials that partially allow light to pass through them are translucent. The objects on the other side of them appear cloudy. And materials that do not allow any light to pass through them are considered opaque. We can't see what's on the other side at all! Kindergartners did the "Can you see the letters?" test to begin classifying materials that are transparent, translucent and opaque!
