Purpose
//What is the fundamental purpose of the device? A blender is an electric appliance, generally used in the kitchen to chop, liquify or mix foods and drinks. They are also used in microbiology, because they can be used to extract bacteria from samples. You can also find blenders in manufacturing plants, where they blend powders and dry materials.//

Energy
//What energy transformations are seen in its operation?// Energy from an outlet or battery is then used to turn the motor which turns the blades. The blades turning creates a vortex which mixes and blends the food or other ingredients.

Controls
//What sensors/controls are designed into the device?//

Materials
//What material(s) are essential to the device?// Batteries or an outlet and a cord for energy. The different pieces of the blender are essential, as well as whatever ingredients you need to make whatever it is you are trying to make, ie. smoothies, milkshakes.

Science
//What is scientific principle is central to its operation?// The blades turn quickly, creating a vortex (a spiral movement in fluid) in the blender. The vortex causes a vacuum at the center, which makes the material in the blender constantly move and mix together.

Design
//What does a typical device look like?// A blender typically includes a base, which includes the motor and the blades, and the controls, a food container, and a lid.The metal that is used for the blender blades is called stainless steel. stainless steel is made up of iron with a percent or so of carbon. they also add a bit over 10% or even 20% of chromium which makes the steel stainless. they sometimes include some nickel or even manganese to make the steel strong. stainless steel is very special because it is reliable and it does not rust,corrode, and does not stain easily like ordinary steel. That is why this type of steel is important. == == == Evolution== //What changes have there been (or could there be) in this device?// Blenders today have programmable controls, multiple speeds,and touchpads.

There are also different types of food containers, including stainless steel, glass, and plastic. Some containers have measurements.

Competitors
//What other devices serve a similar purpose? Handheld blenders- serve the basic purpose of a blender, but is easily portable and can be used to stir things already cooking, such as soups. They don't have as much power, and don't blend as efficiently as standing blenders. Mixers-// used most usually in baking, handheld or free standing blenders have two wisk-like prongs that turn simultaneously to mix ingredients together.

Partners
//What other devices work in conjunction with this device? Other Kitchen Appliances Electric Oven Ice Dispenser Refrigerator Dishwasher//

Siblings
//What other devices use the same scientific principle?// Food Proccessors- Blenders and food processors are sometime mistaken for being the same device. They used the same basic principle, and have areas of use which overlap, but blenders are better suited for liquids, and food processors are better suited for solids.
