Some classic simple science experiments revolve around creating gooey substances. Playing with slime is fun — and surprisingly, you can learn a lot from it, too. As we all know, a slime has a various of description like a gunge , a viscous substance often used in TV game shows; a tire sealant that seals punctures in both tube and tubeless tires and an algae, moss, or mucus secreted by various animals such as snails and fish. Making a slime on your own is one of the simple science experiment that can be done anywhere. in order to make one, you must follow these simple instructions, first, pour a cup of cornstarch into a bowl then Slowly add 1/2 cup of water, just a little at a time, mixing with your fingers as you go. To give your mixture real slime appeal, add a few drops of food coloring. You have just made what is known as a “non-Newtonian” fluid. In the 1700s, Sir Isaac Newton described the properties of ideal fluids. Sir Isaac Newton, born 4th of January 1643 and died on the 31th day of March 1727.

He was an English physicist, mathematician, astronomer, natural philosopher, and alchemist, regarded by many as the greatest figure in the history of science. His treatise Philosophiae Naturalis Principia Mathematica, published in 1687, described universal gravitation and the three laws of motion, laying the groundwork for classical mechanics. By demonstrating consistency between Kepler’s laws of planetary motion and this system, he was the first to show that the motion of objects on Earth and of celestial bodies are governed by the same set of natural laws. The unifying and predictive power of his laws was central to the scientific revolution, the advancement of heliocentrism, and the broader acceptance of the notion that rational investigation can reveal the inner workings of nature. In mechanics, Newton also markedly enunciated the principles of conservation of momentum and angular momentum. In optics, he invented the reflecting telescope and developed a theory of colour based on the observation that a prism decomposes white light into a visible spectrum.

Newton notably argued that light is composed of particles. He also formulated an empirical law of cooling, studied the speed of sound, and proposed a theory of the origin of stars. In mathematics, Newton shares the credit with Gottfried Leibniz for the development of calculus. He also demonstrated the generalized binomial theorem, developed the so-called “Newton’s method” for approximating the zeroes of a function, and contributed to the study of power series. He said that an ideal fluid would have a constant viscosity, or resistance to flow, at a given temperature. Your experiment proved that your ooze is a non-Newtonian fluid because it has the properties of both a liquid and a solid and reacts to stress with increased viscosity. And for your additional information, quicksand is another non-Newtonian fluid. That means the more you struggle against it or try to cut through it — the more resistant it gets, which explains why you shouldn’t struggle violently if you happen to fall into it! What are some other non-Newtonian fluids you use in everyday life? I will you a clue! You might find some of them in a restaurant and others in an art class.

Another simple science experiment that can be performed by amateurs or even kids is making a smear of chick cells. You can check out cells from your own body! The cells on the inside of your cheek are called Squamous Epithelium cells and can be easily viewed with a compound microscope. In anatomy, squamous epithelium is an epithelium characterized by its most superficial layer consisting of flat, scalelike cells called squamous cells. Squamous epithelium may possess only one layer of these cells, in which case it is referred to as simple squamous epithelium, or it may possess multiple layers, referred to then as stratified squamous epithelium. Both types perform differing functions, ranging from nutrient exchange to protection. A simple squamous epithelium is characterized by the presence of squamous cells which are all contact with the basement membrane. The surface squamous cells are irregularly shaped and very flat; so flat that the cell nucleus sometimes creates a bump in the surface of the cell. Gases and other substances can easily diffuse across squamous cells to the underlying basement membrane, and because of their smooth surface, liquids can quickly flow over them. As such, simple squamous epithelia are seen lining body cavities and capillaries to reduce friction, as well as lining the alveoli to facilitate gas exchange. While, a stratified squamous epithelium consists of squamous epithelial cells arranged in layers upon a basement membrane. Only one layer is in contact with the basement membrane; the other layers adhere to one another to maintain structural integrity. Although this epithelium is referred to as squamous, many cells within the layers may not be flattened; this is due to the convention of naming epithelia according to the cell type at the surface. This type of epithelium is well suited to areas in the body subject to constant abrasion, as the layers can be sequentially sloughed off and replaced before the basement membrane is exposed. Stratified squamous epithelium is further classified by the presence or absence of keratin at the apical surface. Non-keratinized surfaces must be kept moist by bodily secretions to prevent them drying out and dying, whereas keratinized surfaces are kept hydrated and protected by keratin. Compound microscopes could be designed to have a magnifying power of 1,000,000 times. It’s resolving power would be no better than that of an ordinary microscope which has a magnification power of 1,500 times. The materials needed in this simple experiment are toothpick which the flat ones work best, plain glass microscope slide, slide cover slip and methylene blue. To make a cheek smear, take a clean toothpick and gently scrape the inside of your cheek. Then wipe that part of the toothpick in the center of your slide. Hold the coverslip with one end flush on the slide and gently wipe the edge of the coverslip along the middle of the slide’s surface. This will smear the cells along the slide, making a layer thin enough to view clearly. Let the smear air dry. Once your smear is dry, add a drop of methylene blue stain to the center of the smear so you will be able to see the cells more clearly. Gently set a coverslip over the smear and scan your slide under low power to locate the cells, then observe them more closely under high power.

Have you ever seen a dancing raisin? Here’s another quick and easy science experiment. All you need is a glass of clear soda, such as ginger ale or club soda, and several small raisins. First, fill a glass with soda. Leave about 1/2 inch or 12.5 mm of space at the top. Then drop the raisins in. See what will happen next. For about a minute or two, you will the raisins move to and fro, up and down and in all directions. Those tiny bubbles attaching themselves to the raisins are carbon dioxide bubbles. Carbon dioxide is an odourless, colourless gas, which is faintly acidic and non-flammable. It is a molecule with the molecular formula CO2. The linear molecule consists of a carbon atom that is doubly bonded to two oxygen atoms, O=C=O. Although carbon dioxide mainly consists in the gaseous form, it also has a solid and a liquid form. It can only be solid when temperatures are below -78 oC. Liquid carbon dioxide mainly exists when carbon dioxide is dissolved in water. Carbon dioxide is only water-soluble, when pressure is maintained. After pressure drops it will try to escape to air, leaving a mass of air-bubbles in the water. The irregular surface of the raisins enables a lot of CO2 to accumulate. When enough gas bubbles attach to the raisins, they act like tiny balloons, giving the fruit enough lift or buoyancy to rise. The raisins should rise to the top of the glass and float on the surface. As the carbon dioxide escapes into the atmosphere, though, the raisins will sink. Then the whole process will repeat itself time after time — so the raisins seem to dance. What other small objects might work in this experiment? Try out a variety of objects, and see if you can tell what properties the objects need to share for this experiment to work. Carbon dioxide gives soda its fizz. Alka-Seltzer medicine uses fizzing bubbles to make people feel better fast. How does this work? The bubbles tickle the exit valve of the stomach, making it open sooner than normal, which allows the medicine to get into your system more quickly.
