This in an Animal Unit designed for third grade science curriculum. It includes information on animal life cycles, inherited traits, and habitats.


Organisms (plants and animals, including humans) have unique and diverse life cycles, but they all follow a pattern of birth, growth, reproduction, and death. Different organisms vary in how they look and function because they have different inherited traits. An organism’s traits are inherited from its parents and can be influenced by the environment. Variations in traits between individuals in a population may provide advantages in surviving and reproducing in particular environments. When the environment changes, some organisms have traits that allow them to survive, some move to new locations, and some do not survive. Humans can design solutions to reduce the impact of environmental changes on organisms.

Life Cycle

Organism Life Cycles: Organisms have unique and diverse life cycles but follow a pattern of birth, growth, reproduction, and death. Examples of changes in life cycles could include how some plants and animals look different at different stages of life or how other plants and animals only appear to change size in their life.


Go to page two on the google site and watch the brainpop video, go through the lesson on bats, read and answer question using Kami on Bats, then watch the youtube video on bats.

Your assignment is to research about an animals life cycle and create a life cycle Jamboard. As a class, do one on bats then have them do their own research using world book online to create a jamboard on their own animal.

Inherited Traits

Identify patterns of traits that plants and animals have inherited from parents. There are similarities and differences in traits between parent organisms and offspring and variation of traits in groups of similar organisms.

View page three of the site and learn about owls using nearpod, pdf reading, and the youtube video.

Then go through the hyperdoc about the zoo. This was created because my class went to the zoo. You may want to include a virtual field trip to the zoo for this to make sense.



In a particular habitat (system) some organisms can survive well, some survive less well, and some cannot survive at all. Organisms and habitats form systems in which the parts depend upon each other. Examples of evidence could include needs and characteristics of the organisms and habitats involved such as cacti growing in dry, sandy soil but not surviving in wet, saturated soil.


Learn about Spiders habitats using brainpop, google slides, and the comprehension pdf (I recommend assigning it through Kami for your students).

Then click on the google earth link to see where some of these animals live and learn a bit about them.
