Change in the Uinta Mountains

Four separate, standards-aligned investigations designed to engage your students in the phenomena of change and stability in ecosystems. Using a combination of museum specimens, simulations, and authentic data, your students will explore rapid changes being observed in the Uinta Mountains of Utah. Each of the four investigations targets a key question about the ecosystem and can be used alone or in combination.

Target Audience: 6th-8th Grades

Standards Alignment:
Utah SEED standard 6.4 and NGSS MS-LS2, as well as, DOK levels 1-4 and ELA Common Core Standards.

Uinta Mountain Investigations:

What's killing these trees?

Total Estimated Time: 2.5-3 hours

Students will define the problem by identifying dead pine trees in aerial images of the Uinta Mountains. They'll determine whether the amount of dead trees currently found is significantly different than the historic average and identify the resources a tree needs to survive along with clues that can tell them which resources the trees may not be getting. Students will analyze tree samples and images to gather evidence that can help explain what's happening to these trees. Finally, they will use historical temperature and precipitation data to develop an explanation for why this montane environment is changing.

SECTION 1: GATHER
How many lodgepole pines are dying?
(50 minutes)
SECTION 2: ANALYZE
What is killing the lodgepole pines?
(70 minutes)
SECTION 3: INTERPRET
Why now?
(50 minutes)
SECTION 4: COMMUNICATE
And why is it worse now than in the past?
(30-60 minutes)

 

Who wins and who loses in a rapidly changing forest?

Total Estimated Time: 1.75-2 hours

Students will query collections for organisms from montane forests in the Uinta Mountains. They’ll classify organisms (predator, competitor, mutualist) based on their relationship to the lodgepole pine using field notes and previous knowledge, then create a model to communicate and reason about the impacts of change on these interactions.

SECTION 1: GATHER
How do museums gather their biological collections?
(30 minutes)
SECTION 2: ANALYZE
What relationships do lodgepole pines have?
(20 minutes)
SECTION 3: INTERPRET
How might decreasing lodgepole pine tree populations impact other organisms in the Uintas?
(25 minutes)
SECTION 4: COMMUNICATE
Who wins and who loses in a rapidly changing forest?
(40 minutes)

 

How is energy transfer and matter cycling affected in a changing ecosystem?

Total Estimated Time: 2.5-3 hours

Students will use a food web model to gather data and classify which roles (producer, consumer, and decomposer) each organism plays in this mountain ecosystem. In doing so, students will reason how energy and matter are impacted by the change taking place in this environment. Students will develop and use models to explain their thinking.

SECTION 1: GATHER
What does normal look like in this forest?
(20 minutes)
SECTION 2: ANALYZE
How does energy flow in this ecosystem?
(60 minutes)
SECTION 3: INTERPRET
How does energy flow change as lodgepole pines continue to die off?
(25 minutes)
SECTION 4: COMMUNICATE
How will the loss of lodgepole pines affect the energy producers in this ecosystem?
(45 minutes)

 

What is the future of a forest under attack?

Total Estimated Time: 3-4 hours

Students will build an energy pyramid model to visualize populations of producers, consumers, and decomposers in this mountain ecosystem and how biotic and abiotic changes may impact those populations.

SECTION 1: GATHER
How do biotic and abiotic changes impact an ecosystem?
(45-60 minutes)
SECTION 2: ANALYZE
What happens when change occurs in an ecosystem?
(40-50 minutes)
SECTION 3: INTERPRET
What is the future of organism populations in this forest?
(45-60 minutes)
SECTION 4: COMMUNICATE
What does the future look like for a forest under attack?
(45-70 minutes)
