| 1 |
Percolation |
Observe the different rates of percolation in several particle sizes. |
| 2 | Pond Slime | Make observations on the pond and its relationships with the abiotic and biotic factors in that ecosystem. Think about the pond and its role in a food chain. |
| 3 | Soil Hike |
Take a hike and think about the different relationships that soil has with the living things that interact with it: plants, animals, etc. |
| 4 | Particle Size |
Identify the different particle sizes in soil and discuss the processes that are involved creating the soil that is found at the delta. |
| 5 | Weather | Use various measuring instruments to collect data on the weather present at the delta. |
| 6 | Protect the water |
Reflect on things you can do to conserve water and envision what a perfect environment would look like. |
Due to the size of most middle/high school trips, we usually do the grade levels over a series of days. During the field trip, a number of stations will be run by the teachers and staff. Students will visit these stations in a round robin fashion. The activities provided are sample trips for each grade level, but as always, you may customize your field trip by meeting with the educator.
For more information in planning your field trip or to customize a trip, please use our teacher workbook.
