You are going to create your own model that shows the movement of matter among plants, animals,
decomposers, and the environment.
Part One
You will create a 3-D model (diorama) or a 2-D model (poster) showing the movement of matter. Your
model must include the following:
• labels of plants, animals, decomposers, and the environment
• descriptions of plants, animals, decomposers, and the environment
Brainstorm ideas about what you want to create. Think about the materials you would like to use and
what you need to gather or buy. Write your list in the space provided.





You can now choose to take a picture and write a description of your model, or record a video of
yourself explaining the movement of matter. If you are writing your answers, follow the next set of
instructions.
Write a detailed description of your model and how it describes that matter is moved from plants,
animals, decomposers, and the environment.

There are 3 types of polar bears: ones with thick coats, ones with thin
coats and ones with medium coats. It is fall, soon to be winter. The temperatures are dropping rapidly and the bears must be kept warm, or they will freeze to death. Many of the bears have had ~2 cubs each
but due to the extreme temperatures, many mothers only have one cub left.
Identify a type of variation in the polar bears ______________________________________________________ Which variation is most favorable? _______________________________________________________ In 50 years, what will natural selection have most likely done to the polar bears? _________________________________________________________________________________

There are 2 types of worms: worms that eat at night (nocturnal) and
worms that eat during the day (diurnal). The birds eat during the day and seem to be eating ONLY the diurnal worms. The nocturnal worms are in their burrows during this time. Each spring when the worms
reproduce, they have about 500 babies but only 100 of these 500 ever become old enough to reproduce.
Identify a type of variation in the worms.

Which variation is most favorable? _______________________________________________________ In 50 years, what will natural selection have most likely done for the worms? _________________________________________________________________________________ What adaptations might occur in the birds in 100 years? ______________________________________ ________________________________________________________________________________________
