Helpful websites

You may want to direct your students to some or all of these websites to help with their investigations.

Atlantic salmon:

Grizzly bears:

At this website, there is a camera that can show you what the bears are doing at Brooks Falls.

The bears are there during summer. The rest of the year the website shows video of what the bears were doing last summer.

How to search the internet

1 Keep your request short

Fewer words will give a more accurate search.

2 Choose exactly what you want

For example: Arctic Circle Climate

3 Use quotes

Double quotes around a set of words tell the search engine to consider those exact words in that exact order without any change. For example: “Arctic Circle Climate”

4 Use the plus sign (+)

If you add a plus sign (+) between words, the internet will search for all the words. For example: migrate+birds+whales+mammal

5 Use the minus sign (–) to say what you don’t want

Use a minus sign (–) to show words you do not want to appear in your results. For example: if you search for burrowing animals and do not want mammals in your search,  –mammals will exclude mammals. Note that you need to put a space before the minus sign for the word to be excluded.

6 Be very clear about what you don’t want

Part 1
Ask questions and make predictions

After reading The Salmon Stream, you may have many questions about the relationship between different species of animals.

List your questions.

  • Compare your list with questions that others have.
  • Choose a question you would like to investigate.
  • You can work alone, with a partner, or in a small group.

You may want to choose one or more of these questions to investigate

Q1. Investigate other species of animals that have very different life cycles that come together at specific times during a year.

Q2. Salmon lay a huge number of eggs in an extremely difficult place to spawn. Why do they do that? What other species have a life cycle that is similar to this?

Q3. Investigate the ways in which climate change may affect the grizzly bear.

Part 4
Evaluate the information

1.  Look over the information you have gathered and the patterns you have found.

What brings the life cycles of your animals together?

Why does this happen and are both animals better off for this?

2. Search for other patterns.

What do these patterns tell you about life cycles? Why? What might happen in the future? Do you think that climate change will affect these animals? Why?

3. Make notes about what you find.
