Answers
1
What can the consensus model be used to explain
How an odor and air are the same stuff
How molecules are made up of atoms
How air and odor exist in 3 dimensional space
How an odor travels from the source
2
What four things should the key to our consensus model for how we smell have?
Air atoms, Odor atoms, Source, and Movement
Air particles, Odor particles, Source, and Movement
Expansion, Compression, Movement, and Air
Expansion, Compression, Evaporation, and Elements
3
Which of the following is a molecule
Zinc
Copper
Iron
H20
4
Substances have different odors because they have different
Types of atoms
Arrangement or structure of atoms
Type, number, or arrangement of atoms
Numbers of atoms
5
What phase can particles travel and spread in all directions
Phase 9
Liquid
Gas
Solid
6
Is air a pure substance or a mixture?
Mixture
Pure substance
7
What is an advantage of the simulation over the consensus model?
All models have advantages and disadvantages, this being all
It is better
It demonstrates actual movement
It demonstrates the odor coming from the source
8
Different materials
Can have similar properties but must have some different
Have all the same properties
Can't have any of the same properties
Are all made of the same particles
9
Which of the following is an element
Iron
Salt
Ammonia
Water
10
Who invented the periodic table of elements?
Edward Nigma
Albert Einstein
Dmitri Mendeleev
Isaac Newton
11
A molecule
Makes up an atom
Is used to make science confusing
Is a particle that is distinguished and unrelated to atoms
Is made up of two or more atoms
12
What phase change is responsible for how a smell is able to travel in the air to the nose
Freezing
Condensing
Evaporation
Melting
13
What is an example of why properties matter? eh get it, matter :)
E-nose and medicine
Food and beverages
Developing materials to make space travel possible
Building materials
14
What is a property in chemistry?
A characteristic used to describe different materials
An element used to describe different types of atoms
My massive mansion
An element made of one type of atom
15
The indicator paper turned blue when placed in the ammonia flask because
Some liquid ammonia atoms released into the air
Mr. Wynne colored it
Some liquid ammonia molecules evaporated and spread
The ammonia was boiled and released particles into the air
16
What is an advantage of the consensus model over the physical model
It is able to show what a molecule is made up of
All models have advantages and disadvantages but this one
It is able to show that the smell starts from the source
It is easier to understand
17
An element is
Earth, Water, Wind, or Fire
Composed of many different types of atoms
Another word for a molecule
Made of one type of atom
18
Which of the following IS a property
Odor
Size
Mass
Volume
19
The physical models we created can be used to explain that air is
One giant molecule that sweeps through the galaxy
Made of different atoms which are made of molecules bonded
Made of atoms that stay in place
Made of different molecules which are made of atoms bonded
20
Which of the following is NOT a property
Volume
Odor
Color
Hardness
