Speed Unit Vocabulary
Due Date: 10/27/2017
Subject: Science

 

Distance

A measurement of length between two points, units of measurement, millimeters, centimeters, millimeters, inches, feet, yards, miles.

TimeTett   Time

A unit of measurement that explains the passage of a existance, unit of measurement, seconds, minutes, hours, days, years

Speed

Speed is a unit measurement that identifies a rate of motion.

Units of measurement (kilometers per hour (km/hr) or mph, or m/s

Average Speed

The average speed something is moving at, the total distance divided by the total time it took to get from one point to the second point.

Speed = distance / time (s = d/t)

Instantaneous Speed

A snapshot, or exact moment something is traveling.

Velocity

The speed measurement and the noted direction the object is traveling. Speed and direction

Initial Velocity

The beginning/start of where velocity is measure, used in formula for acceleration, before the object accelerates.

Final Velocity

The final point where velocity is measure, used as the end point for the formula of acceleration, final point in time.

Acceleration

The rate at which velocity changes, uses the formula:

acceleration = Final Velocity - Initial Velocity

                                 Change in Time

       Acceleration = FV  -  IV

                                   Time


Unit of Measurement    Kilometers per second squared  (km/s²) or any distance with the second squared



Vocabulary: Rocks 8 28 2017 - 18
Due Date: 8/29/2017
Subject: Science

7th Grade Science Rock Vocabulary

Vocabulary: To earn 10 Point on Unit Summative assessment

Students are to write definitions in their own words if possible, draw a picture of the definition showing understanding of the concept, and color.

1.         Metamorphic Rock: A type of rock that is created from other rocks, (sedimentary, igneous, and metamorphic) because heat and pressure have been applied.  It changes not only the appearance but also the chemical composition. Common metamorphic rocks are called marble, gneiss, schist.and gems and precious stones are other examples.

2.         Heat and Pressure:   Heat is the changein temperature, it raises, and pressure can be caused from being underground or pushed together from Convergent or Transform boundaries.    Metamorphic rocks are most often found in mountainous regions where the rock is under extreme pressure that causes the temperature to raise. Gems and precious stones are examples of Metamorphic rock.

3.         Foliated: The texture of metamorphic rock in which the mineral grains are arranged in bands or patterns. Foliated metamorphic rocks such as gneiss, phyllite ,schist, and slate have a layered or banded appearance that is produced by exposure to heat and directed pressure

4.         Non-foliated: the texture of metamorphic rock in which the minerals grains are not arranged in any pattern. Non-foliated metamorphic rocks such as hornfels, marble, quartzite, and novaculite do not have a layered or banded appearance.

5.         Igneous Rock: A type of rock that is created from the melted rocks and minerals in the mantle (Magma) that has cool and formed rocks.

6.         Intrusive Igneous Rock: It is the Igneous rock that forms deep in the Earth below the surface. (IN-intrusive-in the Earth).  They form when magma cools slowly below the Earth's surface. Most intrusive rocks have large, well-formed crystals because the slow cooling allows the crystals to form. Examples include granite, gabbro, diorite and dunite.

7.         Extrusive Igneous Rock: It is the Igneous rock that forms as a result of volcanic activity throwing outside the Earth at the surface or slow seeping of lava from vents. (EX-exit-extrusive-exits the Earth).  Most extrusive (volcanic) rocks have small crystals because the rock cools very fast limiting time for crystals to form. Examples include basalt, rhyolite, andesite, and obsidian.

8.         Magma: It is a very hot, thick liquid of melted materials from Earth such as rocks, minerals, and gases. Magma is in the mantle just below the Earth’s crust. If it is under Earth’s surface it is called Magma, and if it is on the Earth’s surface it is called Lava.

9.         Sedimentary Rock:  It is a type of rock that is created from layers of sediment building up over time and extreme pressure smashing it together. Sedimentary rocks are formed by the deposition and subsequent cementation of that material at the Earth's surface and within bodies of water and over time becomes buried under the surface. Sedimentation is the collective name for processes that cause mineral or organic particles(detritus) to settle in place

10.  Sediment: Small pieces of rock, dirt, or minerals that collect from weathering or erosion that build into piles.

 Vocabulary:

  1. Mineral: a naturally formed inorganic solid that has a definite crystalline structure
  2. Element: a substance that cannot be separated or broken down into simpler substances by chemical means
  3. Compound: a substance made up of atoms of two or more different elements joined by a chemical bonds
  4. Crystal/Crystalline: a solid whose atoms, ions, or molecules are arranged in a geometric, repeating patter throughout the solid
