What is the INTEGUMENTary system?
Project Proposal
1). Description of Model
Our model consists of a clear glass casserole dish filled with (from bottom to top) a layer of soil, then saran wrap, then more soil, then grass seeds with chicken wire laid over it. Water is then poured over the grass, and a fan evaporates the water.
2). Drawing

2). Drawing
3). Functions it will perform
-Cools skin through evaporation
-Regulates temp.
-Grows hair
-Protects
-Absorbs some moisture
-Waterproof
4). Materials needed
-Grass
-Soil
-Saran Wrap
-Dish
-Fan
-Chicken Wire
-Water
- Timer Switch

5). Construction plan
Layer materials in pan from the bottom up
6). Biology/Chemistry/Physics principles used
Growth
Evaporation
Absorption
7). Special needs
N/A
8). Unresolved issues
We are not sure how much water we need; we need enough to not be absorbed by the soil, but not so much that it floods the grass (no rice fields please).

Final project Presentation
reflection questions
Discuss your Organ System:
1). What organ system are you modeling?
1). What function(s) does your model demonstrate? How does it demonstrate each function?
1). How did you come up with ideas?
2). How did your group decide on the ideas/plan that resulted in your model?
1). Who did what in your group?
1). What organ system are you modeling?
- Integumentary System
- Protection - Impermeable
- Regulate Temperature
- Eliminate Waste Product
- Senses Changes in Environment
1). What function(s) does your model demonstrate? How does it demonstrate each function?
- Protection - plastic box/chicken wire
- Semipermeable - saran wrap
- Regulate Temperature - heat lamp/fan
- Pores - chicken wire gaps
- Hair Growth - homegrown grass
- Sense Change to Environment - growing grass
- protect UV radiation - put umbrella over
- protect against diseases - spray pesticides
- photosynthesis
- growth
- absorption
- evaporation
1). How did you come up with ideas?
- brainstorming, throwing out random ideas
2). How did your group decide on the ideas/plan that resulted in your model?
- we went with the one that could most display different functions of our system
- a shoe, a candle, and a sock
- we figured it wouldn’t be professional to turn in a shoe and using a candle to represent sweat would be the only function
- grass wasn’t growing
- we planted a new box with fresh seeds instead of old
- how to represent heating/cooling
- we used a heat lamp/fan
- twice
1). Who did what in your group?
- Mikayla - brought in needed materials, helped construct planting box, worked on powerpoint/google doc
- Toran - brought old grass seeds, helped construct box (cut chicken wire) and work on original powerpoint, brainstorm
- Kyle - watered soil, plant seeds/fertilizer, helped answer questions, brainstorm ideas
- Cole - brainstorm ideas, planted seeds, built model
- through open discussions and brainstorming
- We used our members’ talents in the design and building process, and people volunteered to bring in specific items
- How was the work managed in your group? Was there a leader? Did you choose a leader? How?
- Mikayla naturally came into the role of being our leader
- How did you resolve disagreements?
We talked about them and made a mutual decision
- How could what you learned during this project, your model, the concepts used in your model or the design and building process contribute to/ help a real life situation?
- .we learned how to work with eachother.
