Grade 6 Terminology
Gravity
the force that attracts sources of mass together (ex. humans and the Earth)
List the 2 natural forces that act on a plane
Gravity / Drag
Mixture
something that is made up of two or more different substances
What is the universal solvent?
Water
What is the largest animal in the world?
Blue whale
Lift
an upward force (counteracts gravity)
List the 2 man-made forces that act on a plane
Thrust / Lift
Solution
a mixture that has the same appearance throughout but is made up of two or more substances
In what state are particles the farthest apart from each other?
Gaseous state
What instruments does Ms. Bowman play well?
Clarinet, flute, saxophone
Thrust
the forward force of a plane/jet (counteracts drag)
What must occur for a plane to fly?
High air pressure beneath the plane's wings to generate lift and the plane's engines to generate thrust
Solute
the substance that is being dissolved
How can you change a substance that has reached saturation?
Heat the substance to add more solute
How many ribs are in the human body?
24 (2 pairs of 12)
Drag
the natural force that acts against thrust
What must occur for a plane to land?
Gradual release of high pressure beneath a plane's wings to reduce lift
Solvent
the substance that does the dissolving
State 2 points of the particle theory
1. All matter is made up of particles
2. All particles of one substance are identical
3. The particles of matter are in constant motion
4. Temperature affects the speed at which particles move
5. Particles have forces of attraction between them
6. There are spaces between particles
What is the name of the primary gas in Earth's atmosphere?
Nitrogen
Aerodynamics
the study of the properties of moving air
List one or more additional mechanisms on a plane
elevator, air brakes, rutter, etc.
Saturation
the maximum amount of solute that can be dissolved into a given amount of solvent
Use the particle theory of matter to explain why icing sugar dissolves faster than granulated sugar
The particles of icing sugar are smaller than granulated so according to the particle theory, they will dissolve faster
How many elements are on the periodic table?
118 elements
