Question 1

The emergent properties+ex

Answer 1

Individually, an atom has only a few tricks it can perform. When atoms are combined, they acquire new abilities which themselves contribute to larger levels of complexity and even more abilities.

• cell and the human body

Question 2

Property (2)

Answer 2

A distinctive attribute of something: the essence of a thing

Question 3

Molecules (2)

Answer 3

A form of compound in which atoms are joined using fairly fixed bonds called covalent bonds

• group of atoms (two or more atom joined by chemical bonds)

Question 4

Molecular compound (3)

Answer 4

a compound composed of molecules joined by covalent, not ionic bonds
- made up of non-metals
- low melting/boiling points

Question 5

The scientific Method (4)

Answer 5

An investigative approach to acquiring knowledge

-scientists make observations about the natural word
-develop working explanations about what they observe
-test those explanations by collecting more information
- back them up with objective evidence
-publish and share work

Question 6

Hypothesis+2 fundamental elements

Answer 6

a tentative explanation for an observation, phenomenon or scientific problem that can be tested by further investigation

1. Must be testable (there mush be some set of observations or experiments that can be undertaken to support hypothesis
2. Must be falsifiable 9through observation or experiment you must be able to show that the original hypothesis may not be correct
