Leather is a durable and flexible material created by tanning animal rawhides, mostly cattle hide. It is used in a variety of products, including clothing, footwear, bags, and accessories.
How Leather is Made
The process of making leather involves several steps:
Studying the topic of leather can involve learning about the different types of leather, the tanning process, and the diverse uses of leather in everyday products. Understanding the benefits and care of leather can also be important for those interested in working with or using leather goods.
Explore objects that can be manipulated in order to determine cause-and-effect relationships (e.g., distance between objects affecting strength of a force, orientation of magnets affecting direction of a magnetic force) of electric interactions between two objects not in contact with one another (e.g., force on hair from an electrically charged balloon, electrical forces between a charged rod and pieces of paper) or magnetic interactions between two objects not in contact with one another (e.g., force between two permanent magnets or between an electromagnet and steel paperclips, force exerted by one magnet versus the force exerted by two magnets).
Apply scientific ideas about magnets to solve a problem through an engineering design project (e.g., constructing a latch to keep a door shut, creating a device to keep two moving objects from touching each other such as a maglev system).
