Vocabulary
This is the amount of matter in an object. It is measured using a balance.
What is mass?
The breaking down or dissolving of rocks and minerals on the surface of earth.
What is weathering?
Do these items have a density greater or less than water?
Items that sink in water
These items have a GREATER density than water
This is formed when salt is mixed with water.
A mixture, a solution or both?
Both
Salt dissolves in water and a new substance is produced which cannot be separated easily.
Identify the tool used to separate each of the following
Sand and iron filings
Lemonade mix and water
Sand and water
Small rocks and sand
Sand and iron filings - magnet
Lemonade mix and water - evaporation
Sand and water - coffee filter
Small rocks and sand - sieve
This state of matter has a definite shape and a definite volume. The molecules are ordered and tightly connected.
What is a solid?
The low-lying areas between mountains or hills. Many people in ancient times were found in valleys because water runs down from the mountains making them have rich soil to grow crops.
What is a valley?
This is the measure of the amount of space an object takes up.
What is volume?
The moving of pieces of the Earth's surface from one place to another by wind, water, or other natural agents.
What is erosion?
Do these items have a density greater or less than water?
Items that float in water
These items are LESS dense than water.
This is formed when sand is mixed with water.
A mixture, a solution, or both
A mixture because the sand does not dissolve in the water. It settles at the bottom of the beaker.
All metal objects are magnetic. True or False
Explain your answer
False - only metal objects containing iron are magnetic
This state of matter has neither a definite shape or a definite volume. It fills the space that it is in. The molecules are very loosely connected.
What is gas?
A steep cliffs with a narrow valley running between them. It often has a river that runs through the two. They are created through erosion.
What is a canyon?
The force exerted by magnets when they attract or repel each other.
What is magnetism?
The laying down of sediments carried by wind, flowing water, the sea, or ice.
What is deposition?
Which will float in water and why?
A golf ball or a beach ball
The beach ball will float in water because it has less density than water
When one part of a mixtures dissolves into another a solution is made.
Will the parts of a solution maintain all of their physical properties?
No, some of the physical properties will change.
For example when sugar is dissolved in tea- the crystals can no longer be seen but the taste of the sugar can be observed.
Explain why a ping pong ball floats on water but a golf ball which has the same volume as a ping pong ball, will sink in water?
A ping pong ball has less density than water so it floats in the water and a golf ball has greater density than water so it sinks in the water.
This state of matter has a definite volume, the amount is fixed, however it will take the shape of the container it is in. The molecules float and glide across each other.
What is a liquid?
Wetlands that form as rivers empty their water and sediment into another body of water such as an ocean. As silt builds up, new land is formed.
What is a delta?
The ability to be dissolved, especially in water
What is solubility?
weathering breaks it
erosion moves it
deposition drops it
what is block h.
A. This process is used to separate solutions such as a mixture of salt and water.
What is evaporation?
Which of the following sentences is true:
A - All mixtures are solutions or
B - All solutions are mixtures
B - All solutions are mixtures
A mixture is made when two or more substances are mixed together - A solution is a mixture when one part dissolves and spreads evenly in the water
Which of the following is not a physical property of matter?
Size, shape, smell, time, state, density, magnetism
Time
huge hills of sand formed by wind in the desert or even the beach.
What is a sand dune?
The ratio of the density (mass of a unit volume) of a substance to the density of a given reference material.
What is relative density?
Volcanic eruption
earthquakes
landslides
What is greater to least dense - oil, cork, and water?
Water, then oil will float on water, the the cork will float on oil.
In the mixture, this is used to separate the ping pong balls from the marbles and sand.
What is adding water and stir the mixture?
a) gravel and iron fillings
b) sugar, salt, and pepper
c) honey and lemon juice
c) honey and lemon juice
This property of matter determines whether it will sink or float.
What is density? - how tightly packed the molecules are in relation to the size of the object.
A medium size flat-topped mountain or hill with steep sides. They are usually found in dry places.
What is a mesa?
