UNIT OBJECTIVES6-DESCRIBE how humans impact (+/-) biodiversity
Add on to each OBJECTIVE every night as REVIEW!
7-IDENTIFY how biodiversity is increased / decreased

-count trichomes on plants – RECORD – 1 per group
-RECORD OBSERVATIONS quantitative – data table qualitative - descriptions
-determine if your bottle isHAIRY or NON-HAIRY
1.3 LAB: SCIENTIFIC METHOD & BLOODTRICHOMES: -Trichomes are HAIRS found on fast plants.-They are found above the cotyledons and on the stalk of the true leaves.-We are going to COUNT the # of trichomes on the LOWEST true leaf.

YEAST POPULATION
COLLECT a sample of yeast population:-put 1 drop of yeast mixture on a slide-add 1 drop methylene blue to drop of
yeast
LOCATE yeast cells under microscope:-find under low power—focus-turn to medium power—focus
DRAW what your cells look like in your journal-show the groupings/clusters of cells-estimate #s in a single view
RECORD a picture if you can get a good shot
