Page 31 Title: Atoms, Elements, Molecules and Compounds (you will need to make questions and a summary AT HOME and it will be checked)

Atom : 

Atom Smallest unit of matter Can not be divided Contain electrons, neutrons and protons

Element : 

Element A particular type of atom Determined by the number of PROTONS (atomic number) Can not be broken down into another substance B R

Molecule : 

Molecule Two or more ATOMS In a specific arrangement Can be broken down into individual atoms B R B R B R B R You can draw these in a straight line for your notes like R – R – B NOT the same molecule!!!

Compound : 

Compound Two or more ELEMENTS In a fixed ratio Can be broken down into molecules or elements B R B R B R B R Same compound R2B

Guided Practice : 

Guided Practice Draw one atom of “Blue” Draw one molecule of “Green” B G G

Guided Practice : 

Guided Practice What would a molecule of “Blue – Red – Blue” look like? only this What would a compound B2R look like? B R B B R B B R B B R B

Science in the News : 

Science in the News You will work in groups to read and process the article about mercury polluting the atmosphere

Framing questions : 

Framing questions What qualities of scientific investigations are revealed in the article? What questions come to mind about the investigation? What evidence supports the new scientific ideas presented? What evidence or supporting arguments seem to be missing? What kinds of data are discussed or presented (e.g.,  measurements, tables, graphs)?

Hints : 

Hints Remember, the point of investigating this is to focus on mercury If you’re group is not talking about mercury, then you’re not on the right topics
