Resistance is a measurement of the difficulty level of electrons to flow through a particular object. Resistance is similar to the friction an object experiences when it moves or is moved over a surface. Resistance is measured in ohms; 1 ohm is equal to 1 volt of voltage divided by 1 ampere of current.

Static electricity is caused by electrical charges that build up on clothes due to friction and dry conditions. There are several ways to get rid of static electricity quickly, although you may have to change the way you wash and dry your clothes if static electricity is a big problem in your wardrobe.

Velocity is a measure of how fast an object is moving. The object's speed is the total distance traveled in a given time. The units for speed are miles per hour (miles/hour or mph), centimeters per second (cm/second or cm/s), meters per second (m/second or m/s), or kilometers per hour (km/hour or kph).

"Inductance" refers to mutual inductance, which is when an electric circuit creates a voltage due to changes in current in the other strand, and self inductance, which is the creation of a voltage in the strand due to its own current.

Dropping eggs is a classic science experiment, but it's still pretty scary if you've never done it before. In order to be able to drop an egg without breaking it, you must find a way to minimize the impact force of the impact and its effect on the fragile eggshell.

Distance, often given the variable “s”, is a measurement of space that is a straight line between two points. Distance can refer to the space between two immovable points (for example, a person's height is the distance from the bottom of the feet to the top of the head) or it can refer to the space between the current position of an object in motion and the initial location where the object began to move.

Having trouble solving physics problems? There is a simple and logical sequence of processes in solving all physics problems. Step Step 1. Calm down It's just a matter of physics, not the end of your world. Step 2. Read your entire problem once If the question is long, read and understand the parts until you understand a bit.

Horsepower is a unit of measurement of power. This unit was originally created by an engineer from Scotland to compare the power of a steam engine with horsepower. This article will show you how to calculate the engine horsepower of a car, electric motor, and your own body.

Just finished doing physics experiments and assigned to make a report? Although it sounds like a hassle, in fact the process of making a research report is not that difficult. Remember, the main purpose of a report is to explain the series of research processes you went through to people who are unfamiliar with – and want to learn from – the research.

Longitude and latitude are points on the globe that help you find a specific location. When writing longitude and latitude, you need to make sure the format and symbols are correct so they can be understood. You can identify and write various points of longitude and latitude on the map.

Making an artificial model of the earth is a fun activity for learning geography, geology, and astronomy. Grab your paint and start making an imitation of the earth. Step Method 1 of 3: Creating an Earth Model Step 1. Start by preparing a large styrofoam ball Usually, you can get this kind of ball at a craft store.

Have you ever wanted to create a map to fill out your fantasy novel, or create a personal memento of a place you've been? With just a little planning and designing, you'll be a mapmaker in no time! Step Part 1 of 3: Designing a Map Step 1.

Whenever you want to memorize a list, you have to say it aloud over and over or write it down as often as possible. The 50 states' names is a long list to read over and over, but it's easier to have a specific song or phrase to help you memorize them in order.

Memorizing country locations on a world map can be a tedious task, but there are ways that make the process easier. Make sure you use the most up-to-date maps and memorize the names of the countries by continent so the learning process isn't too intimidating.

Learning geography can be a very stressful task. Geography is a broad subject that involves many different areas. Remembering the names of places without much context can also be tedious and difficult. However, mastering geography can make you feel like you've accomplished something and help you know more about the world.

It can sometimes be difficult to study material for a geography exam, especially since it requires memory skills and the ability to draw maps and cities, which is definitely not easy. Not to mention the sheer number of special terms that can be confusing and jumbled up in your head, especially if geography isn't your type of subject.

In chemistry, dilution is the process of reducing the concentration of a substance in a solution. Chain dilution is the repeated dilution of a solution to increase the dilution factor rapidly. This procedure is usually performed in experiments that require very dilute solutions with high accuracy.

In chemistry, electronegativity is a measurement of the degree to which an atom attracts electrons in a bond. Atoms with high electronegativity attract electrons strongly, while atoms with low electronegativity attract electrons weakly. Electronegativity values are used to predict the behavior of different atoms when bonded to each other, making it an important skill in basic chemistry.

Spectrophotometry is an experimental technique used to measure the concentration of a solute in a particular solution by calculating the amount of light absorbed by that substance. This technique is very useful because certain compounds will also absorb different wavelengths of light at different intensities.

Bond energy is an important concept in chemistry that describes the amount of energy required to break bonds between covalent bond gases. Fill-type bond energies do not apply to ionic bonds. When 2 atoms bond together to form a new molecule, the degree of bond strength between the atoms can be determined by measuring the amount of energy required to break the bond.

If you want to test the alkalinity (base) or acidity of a liquid, just use the pH strip to help determine the level. If you've never used a pH strip, it looks like a plain strip of paper and the colorful chart looks like the stuff you'd see in art class.

In chemistry, solubility is used to describe the properties of solid compounds that are mixed and completely dissolved with a liquid without leaving any insoluble particles. Only ionized (charged) compounds can dissolve. For convenience, you can simply memorize a few rules or refer to a list to see if most solid compounds will remain solid when placed in water or will dissolve in large quantities.

Many chemicals are available in liquid rather than solid form. Liquid chemicals are easier to use and measure than solids, especially since solids are generally available in powder form. However, the stoichiometry for chemical reactions becomes more complicated in liquid form.

Ionic compounds are a type of chemical compound composed of metal cations (positive ions) and non-metallic anions (negative ions). To name an ionic compound, all you need to do is look up the names of the cations and anions that make up the compound and make sure to change the ending of the metal name as needed.

For those of you who work as organizers of large events, most likely dry ice, or better known as dry ice, is a common object. Generally, dry ice is sold in the form of flakes, pellets, or chunks, and is often used to keep certain items cool when transported from one place to another, to produce a smoke effect on stage, or even as an object of scientific experimentation.

Citric acid is a weak type of acid that is naturally found in citrus fruits such as oranges and lemons. Due to its sour and pungent taste (as well as its neutralizing and preservative properties), it is very popular for use in a wide variety of products, such as beverages, food, pharmaceuticals, cosmetics, and cleaners.

Have you ever heard of hot ice? It seemed impossible because ice was usually cold. However, we are not talking about ordinary ice. You can make sodium acetate using the same ingredients that make baking soda volcanoes. When sodium acetate is cooled below freezing, a liquid is formed, ready to freeze at the slightest trigger.

CO 2 is the chemical symbol for carbon dioxide. Carbon dioxide produces the sizzling sound in soda and many alcoholic beverages, the impetus that makes bread rise, the fuel in some aerosols, and pressurized gas in fire extinguishers. CO 2 It can be produced intentionally or as a by-product of another chemical reaction.

The color of the smoke changes depending on the materials being burned. White smoke, in fact, is a water droplet suspension of hydrogen-rich fuel. You can make white smoke at home with a few simple experiments. Step Method 1 of 3: Using Paper To Make White Smoke Step 1.

The body certainly strives to achieve balance and equilibrium. When extra H ions or acids are released, the body experiences a condition called metabolic acidosis. This condition speeds up your breathing rate and lowers your plasma level. The anion difference is used to determine the exact cause of this condition.

Making elephant toothpaste is a fun experiment you can do with your kids at home or with your students in the lab. Elephant toothpaste is a chemical reaction that produces a huge bubble of foam. The movement resembles toothpaste coming out of a tube and is large enough to be used as elephant toothpaste.

Crystallization (or recrystallization) is the most important method for the purification of organic compounds. The process of removing impurities by crystallization includes dissolving the compound in a suitable hot solvent, cooling the solution and saturating it with the compound being purified, crystallizing the solution, isolating it by filtration, washing its surface with cold solvent to remove residual impurities, and drying.

If you want to add a rustic or vintage look to your copper jewelry or homeware, simply add a patina to the copper by oxidizing the copper without having to buy expensive equipment from the store. This method can make the copper brownish black, or green and blue.

There are several ways to separate alcohol from water. The most commonly used method is to heat the solution. Because it has a lower boiling point than water, alcohol will quickly turn into a vapor. This vapor is then condensed (condensed) into a separate container.

The mole is a standard unit of measurement in chemistry that takes into account the different elements in chemical compounds. Often times, the amount of a compound is given in grams and must be converted to moles. Although, the conversion is easy, there are some important steps to follow.

If you accidentally add salt to the sugar bowl or add sugar to the salt bowl, the best option is to discard the mixture and use new sugar or salt. However, if you are interested in separating salt and sugar as a scientific experiment, there are several ways to do it.

Calling this an experiment might be wrong (you're doing a demonstration) but whatever you call it, an explosion is a fun way to have SCIENCE fun! Whether you're looking for ideas for your science project or just want to have some brain fun, we've got some ideas and instructions for making different types of explosions below.

In chemistry, the terms oxidation and reduction refer to reactions in which an atom (or group of atoms), successively, loses or gains electrons. An oxidation number is a number assigned to an atom (or group of atoms) that helps chemists track how many electrons are available for transfer and if a given reactant is oxidized or reduced in a reaction.

Carbon dioxide (CO 2 ) is colorless and odorless so you cannot detect it by direct observation. You must collect an air sample (or a CO. sample 2 ), then performs one of several simple tests to identify the presence of the gas. You can blow the gas as bubbles through the lime water, or hold something lit to see if the fire is extinguished by the presence of CO 2 .

Pulse oximetry is a simple and inexpensive procedure that is used to measure the level of oxygen (or oxygen concentration) in the blood without the need to insert any instrument into the body. The oxygen concentration level should always be above 95 percent.
