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 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? ______________________________________ ________________________________________________________________________________________

In preparing a karyotype, a blood sample is centrifuged to separate the blood cells from the plasma. The plasma is discarded and a hypotonic solution is added to make the cells swell. The solution is centrifuged again. A drop of this material is added to a slide, dried, and stained. The slide is viewed and photographed. Based on this procedure where is the best place to discard the plasma?
