Slide Image
DISCUSS:
What are some ways these living things might interact with salmon?
Slide Image
DISCUSS:
What ideas do you have about how matter from a salmon could get to a tree?
Step
01/20
You’ll work with a partner.
Step
02/20
Get your supplies.
Step
03/20
Make your Matter Journal.
First, fold along the thick black line.
Then, fold along the thin black line.
Step
04/20
Lay out your Forest Ecosystem pages. Make sure they look like this,
with the tree on the left and the bear on the right. Then, use a sticker
at the top and a sticker at the bottom to connect the pages.
Step
05/20
You’ll use beans as a model for matter. Work with your partner to
add matter pieces to represent the soil, the water in the soil, and
the gasses in the air.
Step
06/20
Here’s what our model looks like.
Step
07/20
Read the Trees part of the Matter Journal aloud with your partner.
Look for clues about where matter travels. Use your pencil to
underline any clues you find.
Step
08/20
With your partner, move the matter pieces to show where the
matter travels on its journey through the ecosystem.
Step
09/20
Use your marker to show the path that you just moved the matter
pieces.
Step
10/20
Here’s what our model looks like.
Step
11/20
Discuss.
Then, record your answer for question 1 on your Matter Journal.
Step
12/20
Open your Journal and read the Bears paragraph aloud with your
partner to find clues about where matter travels. Look for clues
about where matter travels. Use your pencil to underline those clues.
Step
13/20
With your partner, first DRAW any parts that are missing from your
forest ecosystem model. Then, move the matter pieces to show
where matter travels. Draw arrows to show the path.
Step
14a/20
Discuss.
Then, record your answer for question 2 on your Matter Journal.
Step
14b/20
Here’s what our model looked like.
Step
15/20
Read the Mushrooms paragraph aloud with your partner
to find clues about where matter travels. Look for clues about
where matter travels next. Use your pencil to underline those clues.
Step
16/20
With your partner, first DRAW any parts that are missing from your
forest ecosystem model. Then, move the matter pieces to show
where matter travels. Draw arrows to show the path.
Step
17a/20
Discuss.
Then, record your answer for question 3 in your Matter Journal.
Step
17b/20
Here’s what our model looked like.
Step
18/20
Discuss.
Step
19/20
Work with your partner to move the matter pieces back to the
trees. Add arrows to show the path of the matter.
Step
20/20
Put all your matter pieces back into the cup.
Discuss with your partner. Then, record your answer to
question 4 on the back of your Matter Journal.

anything that takes up space and has weight; can be in different forms such as solid, liquid, or gas
Slide Image

gas


9 of 14

a state of matter, such as carbon dioxide in the air

the process of matter moving back and forth between non-living and living parts of the environment, like between air and plants

carbon cycle


13 of 14

the process of carbon moving back and forth between non-living and living parts of the environment, like carbon dioxide moving into plants
Slide Image
