Content objective:

What are we learning? Why are we learning this?

content, procedures, skills

Vocabulary objective

Tier II: High frequency words used across content areas. Key to understanding directions, understanding relationships, and for making inferences.

Tier III: Low frequency, domain specific terms

Building on what we already know

What vocabulary & concepts were learned in earlier grades?
Make connections to prior lessons from this year.
This is where we start building from.

A biome is a large area on Earth defined by

(a) average temperature, over the course of a year
(b) average rainfall, over the course of a year
(c) the types of animals and plants living there.

Temperate Rainforest (southern coast of Alaska)

So have you been to the temperate rainforest in Alaska?
A rainforest in Alaska? Surely you must be joking.
I’m not joking, and stop calling me Shirley
– with apologies to Zucker, Abrahams and Zucker

The Tongass National Forest in southeastern Alaska is the largest national forest in the United States. 17 million acres (69,000 km2). Most of its area is part of the temperate rain forest … it is home to many species of endangered and rare flora and fauna. The Tongass, which is managed by the United States Forest Service, encompasses islands of the Alexander Archipelago, fjords and glaciers, and peaks of the Coast Mountains.

Learning Standards

Students should know that: The world contains a wide diversity of physical conditions, which creates a wide variety of environments: freshwater, marine, forest, desert, grassland, mountain, and others. In any particular environment, the growth and survival of organisms depend on the physical conditions. 5D/M1b*

Next Generation Science Standards: LS4.D: Biodiversity and Humans

By the end of grade 8. Biodiversity is the wide range of existing life forms that have adapted to the variety of conditions on Earth, from terrestrial to marine ecosystems. Biodiversity includes genetic variation within a species, in addition to species variation in different habitats and ecosystem types (e.g., forests, grasslands, wetlands). Changes in biodiversity can influence humans’ resources, such as food, energy, and medicines, as well as ecosystem services that humans rely on—for example, water purification and recycling.

By the end of grade 12. Biodiversity is increased by the formation of new species (speciation) and decreased by the loss of species (extinction). Biological extinction, being irreversible, is a critical factor in reducing the planet’s natural capital.

LS4.D: Biodiversity and Humans
 There are many different kinds of living things in any area, and they exist in different places on land and in water. (2-LS4-1)
