Seasons of Change

Learning Objective:

• What is the relationship between seasonal changes and

responses of marine mammals?

Seasons of Change

“Marine Mammals’ Responses to Seasonal Changes”:

• Read pg. 158 and review Figure 8.27 (pg. 159).

With your partner discuss questions 9 & 10.

• Odd # partner will share while even # listens carefully.

• Even # will then make a comparison.

• 2-4 pairs will share their comparisons with the class.

Collaboratively with your group:

• Create a visual representation of the solar radiation changes

that occur between April & May as whales migrate from the

Dominican Republic (23.5° N) to Nova Scotia (45° N).

• Private reasoning time to think about possible ways to draw a

visual representation of solar radiation changes.

• Groups will go around & each member will share their ideas

for drawing a visual representation.

• Groups will choose one idea for their visual representation.

Seasons of Change





• Draw a line down the center of your group’s white board &

use only one side for your visual representation.

• Groups may refer back to the Sun’s Rays activity (pg. 149).

• Now create a visual representation of the solar radiation

changes that occur between November & December.

• Include the whale locations as they migrate back south from

Nova Scotia (45° N) to the Dominican Republic (23.5° N).

• Use the other side of the white board to create your groups

visual representation.

that practice.

In your notebook answer the following questions:

• 11. Based on your knowledge of seasons, why do you think

latitude has an impact on the time of the year when Harbor

Seals have their pups? (Collaborate with partner)

• 12. If it is true that Harbor Seals use longer days and warmer

temperatures as cues to begin pupping, which seal would

have its pups first? (Collaborate with partner)

• Each student will record their groups answer within their

notebook.

• (13) How might the following ecosystems be affected by

seasonal changes? Explain your answer in terms of changes

in insolation/solar radiation?

a. The Polar Seas (Groups A, D, & G)

b. Coral Reefs (Groups B, E, & H)

c. Kelp Forests (Groups C & F)

• Cell phones permitted to research the affects.

Seasons of Change

Example:

Estuaries - Less insolation in the winter months results in

less fresh water flow because river and stream sources are

frozen in snow and ice. Some animals, such as Salmon,

migrate out into deeper waters in the winter. During spring

and summer months melting ice and storms produce a

large amount of fresh water that stir up rich nutrients for

marine organisms and reduce salinity. In summer drought

conditions water temperature and salinity can increase

causing estuarine organisms to find more favorable

conditions.

Modeling Seasons

Explore

The amount of solar radiation received at different latitudes

differs with the time of year.

Twice a year the strongest solar radiation lines up directly over

the Equator.

What are the two times a year?

• Autumnal Equinox (Sep. 22/23)

• Vernal Equinox (Mar. 20/21)

Explore

Once a year, each hemisphere receives direct solar radiation.

What is that time called for each hemisphere?

• Northern Hemisphere = Summer Solstice (Jun. 20/21)

• Southern Hemisphere = Winter Solstice (Dec. 20/21)

Over which part of the hemisphere is the strongest solar

radiation lined up?

• Northern Hemisphere = Tropic of Cancer

• Southern Hemisphere = Tropic of Capricorn

Explore

Different parts of the Earth experience sunlight & darkness over

a 24-hour period.

This daily cycle is called the ______________ cycle.

• Diurnal Cycle
