Unit 1 – EcologyStandards
•S7CS3. Students will use tools and instruments for observing, measuring,
•S7CS5. Students will question scientific claims and arguments effectively.
•S7CS6. Students will investigate the features of the process of scientific inquiry.
Ways of science
•Scientific method
•Ways that scientists follow steps to answer questions and solve problems
Ways of science•Steps in the scientific method▫Note: steps are the same; order can change
▫Question/Problem What do you want to know?
▫Research/Background info Find out more about it.
▫Hypothesis (can be redone) Develop the possible answer If _____________, then __________.
▫Experiment/Procedures Test the possible answer.
▫Analysis/Data Examine the results.
▫Conclusion Is the answer what you thought
it would be? Explain.
Homework (8/18/11)
•Write out directions on how to make a peanut butter and jelly sandwich!
Unit 1 - Ecology(Interdependence of Life
Fall 2011Mrs. Cole7th grade science
Unit 1 – Ecology: StandardsS7L1 Students will investigate the diversity of living
organisms and how they can be compared scientifically.
• b. Classify organisms based on a six-kingdom system and a dichotomous key.
• S7L4 Students will examine the dependence of organisms on one another and their environments.
• c. Recognize that changes in environmental conditions can affect the survival of both individuals and entire species.
• e. Describe the characteristics of Earth’s major terrestrial biomes (i.e., tropical rain forest, savanna, temperate, desert, taiga, tundra, and mountain) and aquatic communities (i.e., freshwater, estuaries, and marine).
•Climate•Water•Sunlight•Wind•Rocks•Think…non-living things
•Plants•Animals•Protists•Bacteria•Think…all living things
Ecology
EcosystemBiome
•a community of organisms (living things - biotic) and their abiotic (non-living) environment
•a very large area characterized by its climate and the plants and animals that live in that area.
Unit 1 – Ecology: Standards•S7L4 Students will examine the
dependence of organisms on one another and their environments.

Terrestrial Biomes•Tundra
▫Climate Average yearly rainfall:
12 to 20 in (30 to 50 cm) Average temps
Daytime: 54ºF (12ºC) Nighttime: -26ºF (-15ºC)
▫Animals Caribou, oxen, reindeer
▫Plants Small shrubs and grasses Layer of soil beneath the surface that stays frozen (permafrost)
Terrestrial Biomes•Taiga
▫Climate Average yearly rainfall:
15 to 30 in.(38 to 76 cm) – mostly snow Average temps
Daytime: 70ºF (21ºC) Nighttime: 20ºF (-7ºC)
▫Animals Beavers, grizzly bears, wolves
▫Plants Dense forests of evergreen trees
Terrestrial Biomes•Coniferous forests
▫Climate Average yearly rainfall: 14 to 29.5 in (35 to 75 cm)
Average temps Summer: 57ºF (14ºC) Winter: 14ºF (-10ºC)
▫Animals Deer, moose, squirrels, insects
▫Plants Trees that produces seeds in cones (evergreen)
Terrestrial Biomes•Temperate deciduous forests
▫Climate Average yearly rainfall: 29.5 to 49 in (75 to 125 cm)
Average temps Summer: 82ºF (28º C) Winter: 43ºF (6ºC)
▫Animals Bears, snakes, birds, insects
▫Plants Trees with leaves that change color and shed
Terrestrial Biomes•Tropical rain forests
▫Climate Average yearly rainfall:
up to 157.5 in (400 cm) Average temps
Daytime: 93ºF (34ºC) Nighttime: 68ºF (20ºC)
▫Animals Most diverse Birds, reptiles, mammals
▫Plants Tall trees that form green roofs (canopy) Vines Low plants
Terrestrial Biomes•Savanna
