An acid is a compound that is defined by its physical and chemical properties. Acids taste sour and react with metals and polyatomic ions called carbonates. A carbonate is a charged cluster of Carbon and Oxygen atoms. In addition, when tested with blue litmus paper, acids turn the paper red. A base or hydroxide, like an acid, is also defined by its properties. Bases taste bitter, are slippery to the touch and turn red litmus paper blue. An example of a base is NaOH or sodium hydroxide.

Erosion includes the chemical and physical breakdown of rocks and their transport from their point of origin to another location. Blowing wind, running water, flowing ice and and gravity are the forces that erode rock and sculpt the landscape. Read more...iWorksheets: 3Study Guides: 1Vocabulary Sets: 4Bacteria are prokaryotes, meaning that their DNA is in the cytoplasm because they do not have a nucleus. In addition to not having a nucleus, bacteria also do not have many of the other structures that are found in a eukaryotic cell. However, they still meet the criteria for being a living organism. There are three different shapes of bacteria: spiral, rod, and spherical shaped.

They are made from carbon, hydrogen, oxygen, nitrogen, and phosphorus. There are two types of nucleic acids. DNA (Deoxyribonucleic acid), the genetic material of an organism, and RNA (ribonucleic acid), the important material in producing proteins within the cell. Read more...iWorksheets: 4Study Guides: 1Vocabulary Sets: 3FreeThe process where one cell forms two identical daughter cells is called cell division. There are three stages of the cell cycle: interphase, mitosis, and cytokinesis. DNA stands for DeoxyriboNucleic Acid.

Because the Earth is a globe, the sun’s rays hit the equator more directly than they do near the poles. A second factor is that the Earth is tilted at 23.5 degrees on its axis as it rotates around the sun. As it does, the Northern and Southern hemispheres are either pointing toward or away from the sun’s rays. Consequently, lands near the equator have smaller temperature fluctuations throughout the year. The climate is predictably warm and humid. Read more...iWorksheets: 3Study Guides: 1Vocabulary Sets: 5The theory of plate tectonics describes the movement of the plates of the lithosphere relative to each other. This movement creates forces that push and pull on the crust. Crustal rock can absorb and store energy, but only so much. There is a point at which the stress is more than the rock can hold and the rock breaks. When the rock breaks, the stored energy is released and this energy travels through the Earth. This sudden release of energy created when rocks break is called an earthquake Read more...iWorksheets: 5Study Guides: 1Vocabulary Sets: 6Elements are the purest form of matter and can not be broken down into any other substance by either a physical or chemical change. There are about 114 elements and they are organized on a modern Periodic Table of the Elements. The Elements are organized by their atomic numbers from top to bottom and left to right. Read more...iWorksheets: 4Study Guides: 1Vocabulary Sets: 2Mechanical energy is the energy of a moving object such as an airplane in flight. Thermal energy or heat energy: When a sidewalk warms up from the sun it now has thermal energy. Electrical energy speaks for itself. Whenever electricity is used, its energy is being used. Chemical energy is the energy that gets released when chemical bonds are broken. Electromagnetic energy is energy that travels in waves.

As one moves deeper, the amount of light decreases, water temperature decreases and water pressure increases. There changing factors determine the zones and habitats and which organisms can live in each. Read more...iWorksheets: 3Study Guides: 1Vocabulary Sets: 5Force is a pull or a push and its strength is measured in units called newtons and represented by the symbol F. Forces can act in combination and produce what is referred to as net force. Gravity is a type of force that pulls objects towards each other and toward the earth. Newton’s first law is that an object that is at rest will remain at rest and that an object in motion will continue in motion.

Plants require sunlight to make food. : Plants have
adapted to living on land by having the ability to obtain water and other nutrients from the soil. Read more...iWorksheets: 4Study Guides: 1Vocabulary Sets: 3Mixtures, unlike compounds, are the physical combination of different substances. Solutions are a type of mixture with at least one solute and solvent. In a solution, finely dissolved particles of a solute are dissolved by the solvent. Read more...iWorksheets: 3Study Guides: 1Vocabulary Sets: 1When motion occurs, there is speed and velocity. Speed is calculated by dividing the distance traveled by the time it took to travel. Velocity has an additional component. Velocity tells you how fast an object is going and where it is going. Therefore, if two objects have the same speed, but are going in different directions, they will have different velocities.

The gas is hydrogen and helium. These dusty clouds are called nebulae. Here these particles start to come together to form planets.

Protists are combined into the same Kingdom because they are all eukaryotes and they live in a liquid environment. There are protists that are unicellular and multicellular.

As viewed from space, the Earth rotates counter-clockwise. This is called prograde rotation. Planets that spin clockwise are said to have retrograde rotation.

A conclusion is summing up the information from an investigation by either supporting the hypothesis or not. Read more...iWorksheets: 4Study Guides: 1Vocabulary Sets: 2The intense heat and pressures in the mantle turn solid rock into liquid magma. Magma comes out through the surface of the crust to form volcanoes. Three volcanoes categories are cinder cones, shield volcanoes and stratovolcanoes. The ash and rock that is extruded by explosive volcanoes is called pyroclastic material. This volcanic mudflow is called a lahar. Read more...iWorksheets: 4Study Guides: 1Vocabulary Sets: 3Weathering is a collection of natural processes that, over time, break large rock into smaller and smaller pieces. Rocks can be broken down by physical processes (called mechanical weathering) and chemical processes (called chemical weathering). Soil is a combination of decomposed rock and organic materials. Read more...iWorksheets: 4Study Guides: 1Vocabulary Sets: 4Work is the exertion of force through a distance. The formula for its calculation is: work =force x distance. For an example, if 5 newtons of force were applied for 5 meters, the amount of work done would be 25Nm. Mechanical advantage = output force/input force. For example, if a machine takes the force coming in and multiplies it three times, the mechanical advantage would be 3. Read more...iWorksheets: 4Study Guides: 1

There are six different types of nutrients that the body needs. They are carbohydrates, fats, proteins, minerals, vitamins, and water. There are three main functions of the digestive system. They are to break down foods into molecules that the body can use, absorb the molecules into the blood and send them all throughout the body, and eliminate wastes from the body.
