write about how 2 students used materials to mimic and learn about the real population and ecosystems portfolio
Materials List:
- Plastic cups
- Soil
- Gravel
- Seeds (grass, flowers, vegetables)
- Water
- Small plastic animals (to represent different species)
- Magnifying glasses
- Small rocks
- Paper towels
- Markers
Procedure:
1. Fill the plastic cups with a layer of soil and a layer of gravel.
2. Plant seeds in the soil to represent plant life in the ecosystem.
3. Add water to simulate rain and hydration for the plants.
4. Place small plastic animals in the cups to represent different species in the ecosystem.
5. Use magnifying glasses to observe the interactions between the plants and animals.
6. Use small rocks to create obstacles or barriers in the cups to mimic challenges that the ecosystem may face.
7. Record daily observations of the ecosystem, including growth of plants, interactions between species, and any changes noted.
8. Analyze the data after a set period of time to determine the health and stability of the simulated ecosystem.
Data Table:
| Day | Plant Growth | Animal Interactions | Challenges |
|-----|--------------|---------------------|------------|
| 1 | Small sprouts | Limited interactions | No challenges |
| 2 | Increased growth | Increased interactions | Added rocks for challenges |
| 3 | Flower blossoms | Competition for resources | Increased barriers for challenges |
| 4 | Harvested vegetables | Predation observed | Drought conditions |

Analysis of Results:
Through the simulation, both students were able to observe and learn about the complexities of population dynamics and ecosystem interactions. They were able to see how changes in one aspect of the system (such as introducing new animals or obstacles) could impact the overall health and stability of the ecosystem. By actively participating in the simulation and recording data, the students gained a better understanding of the interconnectedness of living organisms and how environmental factors can influence their survival. This hands-on approach to learning about ecosystems allowed for a more engaging and immersive experience, leading to a deeper understanding of the subject matter.
