Presentation Transcript

  1. Pre-Trip Visit – Warm Weather Eco-Trekkers

  2. Classroom Pre-work • Activities in your school begin four or five days prior to the Eco-Trekker’s field study and will include: • Producers, consumers, & decomposers. • Food chains. • Competition. • Predators & prey. • Living & non-living factor.

  3. Eco-Chamber • Think about how you will make your eco-chamber. Terrestrial Eco-chambers Aquatic Eco-chamber

  4. Your 5th grade will be divided into four separate groups. Silversides Green Darner Dragonflies Great Blue Herons White-tailed Deer

  5. Bus Ride to Field Study • At your first site, the teacher/naturalist will board the bus and let you know what to bring for the morning.

  6. aquatic ecosystems Shoreline Wetlands

  7. Introduction to the Day • Pass out science logs. • Discuss the details of the day.

  8. Science Logs • Scientists collect data. You will record your data in science logs.

  9. Shoreline Ecosystem • What are the parts of a food chain and how do they interact with each other and their environment?

  10. Non-living Factors • Use four of your senses to identify non-living factors found at the shoreline ecosystem.

  11. Non-living Factors • Thermometers - determine the air temperature and water temperature at the shoreline ecosystem

  12. Non-living Factors • Using a chart of the Chesapeake Bay, predict the salinity of the water of Miami Beach’s shoreline ecosystem.

  13. Non-living Factors • Digital salinity meters - determine the salinity of the water at the shoreline ecosystem

  14. Living Factors • Seine net - collect producers, consumers, and evidence of decomposers

  15. Living Factors: Producers

  16. Living Factors: Consumers

  17. Living Factors: Food Chains • After seining use some of the producers, consumers, and decomposers you collected to create a food chain.

  18. Data collection • Record all the data you collected about the living factors into your science log.

  19. Wetland Ecosystem • Why are sunlight and decomposers important to a successful ecosystem?

  20. Non-living Factors • Use four of your senses to identify non-living factors found at the wetland ecosystem.

  21. Living Factors If students quietly approach the bridge on the boardwalk, it can be an ideal place to observe wetland consumers.

  22. Non-living Factors • Thermometers - determine the air temperature and water temperature at the wetland ecosystem

  23. Non-living Factors • Digital salinity meters - determine the salinity of the water at the wetland ecosystem

  24. Living Factors • Dip net - collect producers, consumers, and decomposers

  25. Living Factors • Look carefully through the detritus for tiny organisms hiding from predators!

  26. Living Factors • Aquatic organisms called macroinvertebrates can often be found in the detritus.

  27. Living Factors: Producers • Identify common producers found in a wetland ecosystem.

  28. Living Factors: Consumers

  29. Living Factors: Decomposers

  30. data collection • Record all the data you collected about the living factors into your science log.

  31. Lunchtime!

  32. Time to take the bus from Miami Beach to Marshy Point Nature Center

  33. Bus Ride to Site Two • At your second site, the teacher/naturalist will board the bus and let you know what to bring for the afternoon.

  34. terrestrial ecosystems Forest Meadow

  35. Forest Ecosystem • How does competition among trees affect the growth of a forest over time?

  36. Non-living Factors • Use four of your senses to identify non-living factors found at the forest ecosystem.

  37. Non-living Factors • Thermometers - determine the air temperature and water temperature at the forest ecosystem

  38. Non-living Factors • Digital salinity meters - determine the salinity at the forest ecosystem

  39. Transects • Used by scientists to count and/or measure something within a defined area

  40. Living Factors • Count and measure trees in a sapling and a mature forest.

  41. Drawing Conclusions • Record the data onto the Tree Tally in order to draw conclusions about competition in a forest ecosystem.

  42. Living Factors: Producers

  43. Living Factors: Consumers

  44. Living Factors: Decomposers

  45. data collection • Record all the data you collected about the living factors into your science log.

  46. Meadow Ecosystem • What are the roles within a predator/prey relationship and how do these relationships affect the number of organisms within an ecosystem?

  47. Non-living Factors • Use four of your senses to identify non-living factors found at the meadow ecosystem.

  48. Non-living Factors • Thermometers - determine the air temperature and water temperature at the meadow ecosystem

  49. Non-living Factors • Digital salinity meters - determine the salinity at the meadow ecosystem

  50. Living Factors • Sweep net – collect producers, consumers, and decomposers
