A mind map visually organizes information.❖ Each branch of

information begins with a key word or phrase that identifies that section

❖ Smaller branches organize the content of the section.

❖ Each part of a branch has a topic

❖ There are different ways to link information

❖ Labelled arrows show connections between branches

At-risk Categories and Definitions of Saskatchewan's Wild Species-at-Risk

Category Definition

ExtirpatedNo longer exists in the wild in Saskatchewan, but exists in the wild outside of Saskatchewan

Endangered Threatened with imminent extirpation or extinction

ThreatenedLikely to become endangered if the factors leading to its endangerment are not reversed

VulnerableOf special concern because of low or declining numbers due to human activities or natural events but that is not endangered or threatened

From:The Wildlife Act 1998 Government of Saskatchewan Environment

The Big Idea:

First Nations and native prairie have both suffered great losses. First Nations are strengthening as they reaffirm their cultural heritages and chart their own futures. Native prairie continues its decline. Can it be strengthened or will more native prairie species disappear without most people even knowing that they existed in the first place?

1. Label each organism as a producer or a consumer.

• Producers get nutrients from the abiotic parts of the ecosystem.

• Consumers get nutrients from the biotic parts of the ecosystem by eating producers or other consumers.

2. Classify each consumer according to what it eats.

• An herbivore munches mostly producers!

• An omnivore feasts on producers and consumers!

• A carnivore devours mostly consumers!

• A scavenger snacks on dead organisms!

Particle Model of Matter

Pure substances contain only one type of atom.

Compounds contain more than one type of atom.

Attractive forces between atoms bind them together, forming molecules.

Carbohydrates (sugars), fats, proteins and DNA are biotic compounds that make up all biotic components on Earth—from bacteria cells to leaves to brains!

Plants build their biotic compounds from simple abiotic compounds like:

Animals get biotic compounds from eating other biotic compounds.
