  1. Detective Tracking and Species Identifying By: Deborah Dietzel

  2. On a trip to GA my fellow science teachers and I came across a whole array of animal tracksin the mud. We need your help in identifyingthem by picking out certain characteristics are unique to the tracks. Are you ready to begin--->

  3. Each animal species (group) leaves a different track behind. • For example the dog species leaves a footprint that is different than our human species in the sand on the beaches Back

  4. As scientists it is important to be be able to pick out characteristics that are unique to the track. • We can use this same technique in identifying plants too. Back

  5. What are we looking for ? • Take a close look at the track. • What kind of observations can you conclude? • Can you rule out a particular species? • How is one track different than the other one ? Back

  6. Here is what we came across. Let’s begin out investigation

  7. Does the track show Only Hand/Feet tracks (challenge) Tail Marks (medium) Hooves (easy)

  8. 4 2 How many fingers/toes/sections can you distinguish? 3

  9. Feral Pig Finished Identifying Try another track

  10. Look Closer Back

  11. White Tail Deer Try another track Finished Identifying

  12. Does the tail occur Alongside footprint tracks? Alone without any other tracks alongside it

  13. Diamondback Terrapin Try another track Finished Identifying

  14. Diamondback Rattlesnake Try another track Finished Identifying

  15. YES NO Are there claws/nails present?Do you know what the scientific name for our thumbs are?

  16. Are the claw marks further apart on track than the other? No Yes

  17. Do the tracks display a thumb-like placement as our handprints do? YES No

  18. Opossum Finished Identifying Try another track

  19. Opposable Thumbs Human thumbs are called opposable thumbs because the thumb can be moved around to touch the other fingers, which gives us the ability to grasp things more easily, pick up small objects, and eating with one hand Most primates (ape, chimpanzees, gorillas, and orangutans, and monkeys) have opposable thumbs or toes.. Humans can move their thumb farther across their hand than any other primate. Back

  20. How many toes/fingers does the track show? 3 4 5

  21. Look Closer Back

  22. Striped Skunk Try another track Finished Identifying

  23. How many toes/fingers does the track show? 3 4 5

  24. Look Closer Back

  25. Nine-Banded Armadillo Try another track Finished Identifying

  26. Common Raccoon Finished Identifying Try another track

  27. How many toes/fingers does the track show? 3 4 2

  28. Look Closer Back

  29. Measurements ¾ inch diameter 6-8 inch length

  30. Wilson’s Plover Finished Identifying Try another track

  31. Tricolored Heron Finished Identifying Try another track

  32. Thanks For Your Help • You are great Science Detectives!

  33. Conclusion • What kinds of observations were easy to characterize? • Can you rule out a particular species? • What are some differences between tracks? • If you did not follow this plan how would you go across trying to figure out what animal the track came from? • By just looking at the track, is there anything that could help you figure out what the animal was?

  34. Let’s make some further observations about • Habitat • Food selections • Ecosystem Placement • Adaptations
