UNIT OBJECTIVES 6-DESCRIBE how humans impact (+/-) biodiversity Add on to each OBJECTIVE every night as REVIEW! 7-IDENTIFY how biodiversity is increased / decreased
FAST PLANTS -# plants use toothpicks to # plants hashmarks for plant # -count trichomes on plants – RECORD – 1 per group -RECORD OBSERVATIONS quantitative – data table qualitative - descriptions -determine if your bottle is HAIRY or NON-HAIRY
1.3 LAB: SCIENTIFIC METHOD & BLOOD TRICHOMES: -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. Fast Plant Ecology: Counting Trichomes Cotyledons TRUE LEAF
FAST PLANTS RECORD OBSERVATIONS -quantitative – data table # plants [total] # each color stem # each color leaf # true leaves/cotyledons on a “typical” plant that represents ALL measure height of plants -qualitative – descriptions PICTURE - drawn or photo all & detailed of a “typical” plant DESCRIBE - what plants look like
1.3 LAB: SCIENTIFIC METHOD & BLOOD TRICHOMES Fast Plant Ecology: Counting Trichomes TRICHOMES

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
