Station #1 - Biodiversity and water environments
Gr. 8 Science - Water Systems on Earth
OBJECTIVES:
 Effectively use the e-notetaking sheet to record terms, sources and your new science insights
 What is the effect of biodiversity and pollution on plant and animals in water environments?
 Each partner has to hand in a copy of their definitions and e-notes.
ASSIGNMENT - PART A
/ 20 marks
a. Organize your notes / definitions in your e-note taking sheet
HOW? Go to http://killarney.vsb.bc.ca/library/research.htm >e-notetaking sheet
MAKE SURE TO SAVE onto your H: drive (or desktop) then e-mail finished chart to yourself
(or you will loose ALL your notes when the chart seizes up)
b. Look up the definitions of the 10 terms below
e.g. Google “hydrothermal vents” +definition
c. Give 1 example of how this term (e.g. pH) effects biodiversity - plant and animals in marine
environments (lakes, rivers and oceans)
