What are Fluids? Required*

A Fluid is a substance that has no fixed shape and continually deforms/flows when external force is applied on it. Fluids are a phase of matter that include liquids, gases and plasmas. Liquids form a free surface (that is, a surface not created by the container) while gases do not.

Examples of a fluid can be oxygen, water, and even air! Not only do we use fluids, such as air and water, to stay alive, the human body is mostly made of fluids. Each of us is about 60–70 % water. Table 2 shows other fluids our bodies make and use.

How does dialysis work?

Sometimes technology is needed to maintain the health of our bodies’ fluid systems. Our body cells produce waste continuously. This waste is carried in the bloodstream and could harm or kill us if it were not removed. For people whose kidneys do not work properly, a dialysis machine performs this function (Photo on the left). Blood flows through a tube into the machine, is cleaned, and then returns to the body. Each dialysis treatment takes four to five hours.

Technology comprises an entire system of people and organizations, knowledge, processes, and devices that go into creating and operating technological artifacts, as well as the artifacts themselves. Modern technology is a product of science and engineering, and technological tools are used in both fields
Science is the study of the natural world, including the laws of nature associated with physics, chemistry, and biology and the treatment or application of facts, principles, concepts, and conventions. Science is a body of knowledge that has been accumulated over time.
Engineering is both a body of knowledge—about the design and creation of human-made products—and a process for solving problems. Engineering utilizes concepts from science and mathematics as well as technological tools.

Magic Milk Experiment

When dish soap is dropped into milk, there is a swirl of activity of soap molecules finding and bonding with fat molecules in the milk. With millions of molecules swirling around looking for mates, the colors in the milk get all mixed up!

Dry Ice Experiment

Dry Ice is a fun and cold experiment. There’s many things you can create, so what can you make with dry ice?
Dry ice is a cool and a fun outdoor experiment. Have you ever worked with it? The big caution is that you don’t want to touch it less it burns your skin. Got that? So it has to be handled with tongs and/or insulated gloves.

DIY Lava Lamp Experiment
