Front 20

What are you attempting to do when testing a hypothesis?

Back 20

Falsify it/Invalidate it

Front 21

What is Occam's Razor?

Back 21

A logical principle that states that one should not make more assumptions than the minimum needed. Leads to Principle of Parsimony.

Front 22

What is the Principle of Parsimony?

Back 22

it underlies all scientific modeling and theory building. Says to choose the simplest explanation.

Front 23

Why is it important to be scientifically literate?

Back 23

We are a science-based civilization

Front 24

What is an element?

Back 24

Smallest unit of matter broken down by ordinary chemical means

Front 25

What is an atom?

Back 25

The primary emergent property.

Smallest unit of matter that retains characteristics of an element

Front 26

What are emergent properties?

Back 26

The characteristics a material has. But when combined by chemical means, it has different characteristics

Front 27

Place the following levels from smallest to largest: atom, biosphere, cell, ecosystem, molecule, organ, organism, population, tissue. Which is smallest level capable of demonstrating all the characteristics of life?

Back 27

atom, molecule, cell, tissue, organ, organism, population, ecosystem, biosphere;

cell

Front 28

What is the core idea that unifies all areas of biology?

Back 28

Evolution

Front 29

Front 30

How can an atom be changed into an ion?

Back 30

Adding or removing electrons

Front 31

How can an atom be changed into a different isotope?

Back 31

neutrons

Front 32

By changing the number of what, the atom becomes a different element?

Back 32

protons

Front 33

What is a polar molecule?

Back 33

It is slightly negative at one end and slightly positive at the other end

Front 34

How do the unique properties of water result from the fact that water is a polar molecule?

Back 34

The positive and negative poles cause adjacent water molecules to become attracted to each other, forming hydrogen bonds. Cohesion, temperature regulation, and water's ability to act as a solvent all arise from the atomic stickiness.
