Benchmarks and Standards

AAAS

• THE LIVING ENVIRONMENT: FLOW OF MATTER AND ENERGY - The chemical elements that make up the molecules of living things pass through food webs and are combined and recombined in different ways (Full Text of Standard)
  
  
• THE PHYSICAL SETTING: THE STRUCTURE OF MATTER - Atoms are made of a positive nucleus surrounded by negative electrons (Full Text of Standard)
  
  
• THE PHYSICAL SETTING: THE STRUCTURE OF MATTER - Atoms often join with one another in various combinations in distinct molecules or in repeating three-dimensional crystal patterns (Full Text of Standard)
  
  
• THE PHYSICAL SETTING: THE STRUCTURE OF MATTER - The configuration of atoms in a molecule determines the molecule's properties (Full Text of Standard)
  
  
• THE PHYSICAL SETTING: THE STRUCTURE OF MATTER - The nucleus, a tiny fraction of the volume of an atom, is composed of protons and neutrons, each almost two thousand times heavier than an electron (Full Text of Standard)
  
  
• THE PHYSICAL SETTING: THE STRUCTURE OF MATTER - The number of positive protons in the nucleus determines what an atom's electron configuration can be and so defines the element (Full Text of Standard)
  
  
• THE PHYSICAL SETTING: THE STRUCTURE OF MATTER - The rate of reactions among atoms and molecules depends on how often they encounter one another, which is affected by the concentration, pressure, and temperature of the reacting materials (Full Text of Standard)
  
  
• THE PHYSICAL SETTING: THE STRUCTURE OF MATTER - When elements are listed in order by the masses of their atoms, the same sequence of properties appears over and over again in the list (Full Text of Standard)
  
  

NSES

• Physical-Science: Energy/Matter Interactions - 3 Each kind of atom or molecule can gain or lose energy only in particular discrete amounts (Full Text of Standard)
  
  
• Physical-Science: Matter Structure/Properties - 2 An element is composed of a single type of atom (Full Text of Standard)
  
  
• Science as Inquiry: 3 Use technology and mathematics to improve investigations and communications (Full Text of Standard)
