INTERDEPENDENCE:
Seasonal Changes in Florida’s Plants
and Animals
Big Ideas 16 & 17
Grade 4
Big Ideas 16 and 17
• SC.4.L.16.2 Explain that although characteristics of plants and animals are
inherited, some characteristics can be affected by the environment.
(Assessed as SC.5.L.17.1)
• SC.4.L.16.3 Recognize that animal behaviors may be shaped by heredity and
learning. (Assessed as SC.5.L.17.1)
• SC.4.L.17.2 Explain that animals, including humans, cannot make their own
food and that when animals eat plants or other animals, the energy stored in
the food source is passed on to them. (Assessed as SC.4.L.17.3)
• SC.4.L.17.4 Recognize ways plants and animals (invasive species), including
humans, can impact the environment. (Assessed as SC.5.L.17.1)
ENGAGE
• Hold your thumbs against your palms
and then untie and tie their shoes.
• If you don’t have laces, write your
name on a sheet of paper.
WERE THESE TASKS
DIFFICULT?
Thumbs are an adaptation that helps us do many
things.
All plants and animals have adaptations that
help them to survive.
What are some plant adaptations?
Plants adaptations allow them to live in
specific environments.
Some adaptations are only helpful because of
the environment in which a plant lives.

and learn about plant adaptations in
different environments.
What are some animal adaptations?
Like plants, animal adaptations allow them to
live in specific environments.
Some adaptations are only helpful because of the
environment in which a plant or animal lives.

a web site and learn about
animal adaptations in
different environments.
How do adaptations help organisms survive?
What are some examples of
Adaptations to seasonal changes?
Changing of color and
dropping of tree leaves
Animal migration
Camouflaging
Animal hibernation
What are some limiting factors
that affect organisms?
1. Predation – the
preying of one
animal on others
3. Disease
2. Climate
What are some limiting factors that
affect organisms?
4. Light
5. Temperature
6. Availability of food
What are some animal instincts?
1. Inherited behaviors
2. Migration
3. Hibernation
What are some animal learned
behaviors?
1. Training & experience
2. Parents teach offspring
3. Offspring teach parents
Structural and Behavioral
Adaptations
Now, let’s take a closer look
at the definition of structural
and behavioral adaptations.
• All organisms have
adaptations that help them
to survive. Some
adaptations are structural
and some are behavioral.
• Structural adaptations are
physical features of an
organism like the bill on a
bird or the fur on a bear.
• Behavioral adaptations are
the things organisms do to
survive. For example, bird
calls and migrations are
behavioral adaptations.
Harmful Effects from animals
1.
2.
3.
4.
Overpopulation
Migration
Predation
Invasive species
How do humans harm
the environment?
1. Polluted water
2. Air pollution
3. Land pollution
4. Ocean pollution
How can we help the environment?
1. reclamation
2. preservation
3. recycling
Let’s Review!
Why do animals need to adapt?
For animals, adaptation is a matter of life or death.
If animals don’t adapt in certain ways to their
surroundings, they will not survive.
 What do animals and plants need in order to
survive?
 In order for plants and animals to survive, they must have
structures, behaviors and physiology that meet the
requirements of their environment.
 What is an example of a plant adaptation?
 For example, in order for plants to survive in desserts, they
must have ways to get their water and other nutrients
from their surroundings. Cactus have spines and/or thick
waxy leaves.
What are other examples?
Group Discussion
Round Table:
Beginning with the tallest
person in your collaborative
group, take turns going
around the table in a
clockwise direction telling
one adaptation made by a
plant which allows it to
survive in its environment.

EXTENSION
Discovery Education: Teacher Boards
Extension
• Take the class on a schoolyard habitat
observation walk.
• Have students keep a list of plants and animals
they encounter. Students can draw illustrations
and/or take pictures.
• Students compare plants and animals found in
the schoolyard to those found in the Everglades
habitats studied.
