Foldable/ magnetism
| Term | Definition |
|---|---|
| Magnetite | Some magnets are found in nature. They are rocks that contain the mineral magnetite. |
| Magnet poles | The parts of a magnetic object where the magnetic force is the strongest. |
| Magnetic force | The attraction or repulsion between magnetic poles (exerts a force!) |
| Magnetite field | The area of magnetic force around a magnet. *can interact w/o even touching |
| Magnet | Any material that attracts iron or material that contains iron. |
| Magnetic domains | All or most of the magnetic domains are facing the same way. |
| Ferromagnetic material | A material that shows strong magnetic properties. |
| Temporary magnets | A magnet made from material that easily loses it's magnetism. |
| Permanent magnet | A magnet made of material that keeps its magnetism. |
| Breaking magnets | If you break a magnet in half ... You just make a smaller magnet w/ a north and a South Pole. |
| Compass | Device that has a magnetized needle that spins freely. |
| Magnetic declination | The angle between geographic north and the north. |
| Van Allan Belts | Two doughnut-shaped regions regions 1,000-25,000 kilometers above earth that contain electrons and protons traveling at high speed. |
| Solar wind | Streams of electrically charged particles flowing at high speeds from the sun. |
| Magnetosphere and Aurora | Magnetosphere- The region of earth's magnetic field shaped by the solar wind. Aurora- A glowing region produced by the interaction of charged particles from the sun and atoms in the atmosphere. |
| Like poles | Repels |
| Opposite poles | Attract |
| Magnetic field lines | Spread out from one pole, curve around the magnet, and return to the other pole. |
| Properties of magnets | 1. Attract iron or materials that contain iron. 2. Attract or repel other magnets. 3. One part will always point north. |
| Magnetic field lines | Never cross |
| Rotation | The spinning motion of a body on its axis. |
| Revolution | The motion of a planet around the sun. |
| What causes the seasons on the Earth? | The Earth is tilted 23.5 degrees. |
| Equinoxes | Days in which day and night are of equal duration. |
| Vernal Equinox | First day of spring. |
| Autumnal Equinox | First day of FALL in September. |
| How do you make magnets? | 1. Placing an unmagnetized ferromagnetic material in a strong magnetic field. 2. Rubbing the same material with one pole of a magnet. |
| How to destroy a magnet. | 1. Dropping it or hitting it hard can cause the domains to be knocked out of alignment. 2. Heating a magnet causes the particles les of that material to vibrate faster and more random, making it difficult for the domains to stay aligned. |
| What does a spinning electron produce? | A magnetic field that makes the electron behave like a tiny magnet Ina atom. |
| The earth is like a | Giant bar magnet |
| Elements | A substance that cannot be broken down into any other substances by chemical or physical means |
| Atom | The smallest particle of an atom |
| Compound | A pure substance made of two or more elements that are combination with other elements |
| Chemical formulas | Compounds are represented by |
| Mixture | Is two or more substance- elements, compounds, or both- that are in the same place but are not chemically combined |
| Heterogeneous mixtures | Consists of visibly different substance or phrases |
| Homogenous mixture | Has same uniform appearance and composition throughout |
| Solution | A mixture in which the molecules of one substance, known as the solute, are dissolved in another substance, known as the solvent |
| Suspension | A mixture in which particles can be seen and easily separated by settling or filtration |
| Colloid | A mixture in which particles do not dissolve, but are too small to see and do not settle out |
| Filtration | The act or process of filtering, especially the process of passing a liquid or gas, such as air, through a filter in order to remove solid particles |
| Magnetic attraction | Passing a magnet over a mixture to remove the magnetic particles from within the mixture |
| Evaporation | The conservation of a liquid into vapor in order to remove it wholly or partly from a liquid of a higher boiling point or from solids dissolved in or mixed with it. Boiling salt water will evaporate the water and leave the salt behind |
| Settling | Allowing a suspension to sit still will cause the larger, heavier particles to settle, or sink to the bottom |
| Chromatography | the separation of mixtures into their constituents by preferential absorption by a solid, as a column of silica or a strip of filter paper or by gel |
| Solvent | The part of a solution present in the largest amount |
| Solute | The substance that is present in the smallest amount |
| Concentration | Refers to the amount of one substance in another |
| Dilute solution | A mixture that has only a little solute dissolved in a certain amount of solvent |
| Concentrated solution | A mixture that has a lot of solute dissolved in a certain amount of solvent |
| Solubility | is a measure of how much solute can dissolve in a solvent at a given temperature |
| Saturated solution | when you've added so much solute that no more dissolves, you have a |
| Unsaturated solution | if you continue to dissolve more solute, you have an |
| Pressure | increase it and you can dissolve more solute, like carbon dioxide in soda. Decrease it and the solute will come out, like when you open soda |
| Type of solvent | certain things dissolve certain things better than others |
| Temperature | for example a hot cup of tea will dissolve more sugar than a cold cup of tea..... but cold soda will dissolve more carbon dioxide gas than warm soda. |
| Energy | the ability to do work. |
| Kinetic energy | energy of motion |
| Potential energy | energy of position, stored energy |
| Nonrenewable energy source | when an energy source can not be replaced in your lifetime it is considered nonrenewable ` |
| Nuclear fission | splitting an atom's nucleus into two small nuclei |
| Nuclear fusion | Combining two atomic nuclei to produce one larger nucleus |
| Renewable energy source | Will never run out, it is sustainable |
| Solar energy | generates heat and energy electricity from the sun directly or using photovoltaic cells |
| Wind energy | converts kinetic energy into electricity using windmills with large blades that require 11-13 mile per hour winds on average to operate and generate electricity. |
| Hydroelectric power | creating dams in running water capture the kinetic energy as it moves |
| Biomass | is using waste products to produce energy |
| Geothermal energy | the intense heat from the earth's interior that warms the magma beneath Earth's surface |
| Law of conservation of energy | energy can not be created or destroyed it can only be converted from one form to another |
| How do you read a solubility chart? | look at the lines |
| Towards the sun | we experience summer |
| Away from the sun | we experience winter |
| Solstices | the winter solstice is the shortest day of sunlight of the year. |
| Result's of the Earth's magnetic field | It is what enables a compass to work. Many animals seem to navigate using it. |
| Domain | causing the material to be magnetized |
