Transcript TAKS Objective 2 - UNT's College of Education

TAKS Objective 5
The student will demonstrate an
understanding of Earth and
Space systems
TEKS Science Concept 8.14 B
Identify that change in environmental
conditions can affect the survival of
individuals and of species
Lesson Objective
The student will be able to describe
environmental conditions that can have
significant impact on the survival of
individuals and species.
Question
True or False: With intervention
any species can be saved from
extinction.
Once a species is threatened or
endangered it is not always
possible to remove the threat or
endangerment. Once a species
drops past a critical number of
individuals, the species will most
likely go extinct regardless of
what we do to intervene
Question
True or False: Environmental
dangers are usually visible.
There are many environmental
problems that are not always
obvious. For example, UV
radiation, CFCs, microscopic
organisms/viruses, and many
forms of pollution cannot be seen
or detected without special
equipment. For this reason, an
individual may not be aware of
the nature of the problem.
Prior Knowledge
1. What is biodiversity?
2. What is the role of sexual reproduction
in survival of organisms?
3. How do changes in the phenotype of an
individual occur?
The Golden Coqui Extinction Dice Game
ENGAGE
99.9% of all species that have ever
lived are extinct. Many of them
perished in five mass extinctions.
According to the America Museum of
natural History and the Louis Harris
Survey research firm, seven out of ten
biologists believe we are in the mist of
a sixth mass extinction
EXPLORE
Get ready to play the Golden
Coqui Extinction Dice Game. Let’s
read the directions together.
EXPLAIN
1. Why are all the graphs not identical?
2. How do the three lines on the graph compare?
3. Under what circumstance might an increased
birthrate have a negative outcome?
4. What are ways that citizens can become active in the
protection of biodiversity?
EXPLAIN
5. What causes a population to grow?
6. What causes a population to decline?
7. What makes a population stay the same in size?
8. Does the size of the population matter? Why or why not?
9. Associate the probability of rolling the dice with the outcome of
the simulation (i.e., what is the probability of rolling a
2,3,4,5,6,7,8,9,10,11,12?
ELABORATE
Explore species no longer found in
Texas using information from the
following website:
http://www.texasep.org/html/wld/wld_3p
na_ext.html
EVALUATE
After completing the learning
experience, The Golden Coqui
Extinction Dice Game” the learner will
participate in a class discussion by
providing at least two meaningful
interactions during the class debriefing
sessions.
EVALUATE
Given information about species which
are longer living in Texas, the student
will conduct web research to determine
the cause of loss for at least three
animals. The information will be
recorded in the science journal.
