Stories in the Sand: Observations of how animals use the Kansas River sandbars in their daily lives
Lesson
This lesson was developed by Dr. Raymond Pierotti, Division of Biological Sciences, University of Kansas
Overview: Students will look over sandbars or sandy
banks along the river. From what they find they will try and
reconstruct who has been there and what might have happened.
Suggested Grades: 5-7 and 8-12
Kansas State Standards can be downloaded from the School Standards page
Objective: Get students to look at marks in the sand
(tracks, scrapes, wet spots, shed feathers and fur, faeces, etc.) as
ways of obtaining information about events and the community ecology of
a location. Appropriate questions to ask the students include; what
tracks can you find? Are these from mammals (including humans), birds,
reptiles, amphibians, even vehicles? How many types of entity (being)
are represented in one area? Which tracks seem oldest? Which are most
fresh? How can you tell?
Materials: Eyes (binoculars if available), book (or
page) of tracks, notebook and pencil (writing instrument should be
something that will not run if the page gets damp). Plastic sandwich
bags and rubber/surgical gloves, Plaster of Paris, Cookie Cutters or
metal rings.
Methods: Walk along a sandbar or sandy shore looking
for any sign (tracks, other marks, scat) of the presence of others
(both human and nonhuman). Try to figure out what the individual who
left the tracks or sign was doing. Have students collect feathers, etc.
and place them in a plastic bag to show others. You can also have them
make plaster casts of prints (a good set of instructions can be found
at www.bear-tracker.com/plastertracks.html)
Make sure that students can observe a fresh area not disturbed by other
classmates (it may help to assign them to different areas in small
groups). Please make sure that students understand safety precautions
and can identify hazards they may encounter such as poison ivy.
Instructors can find information about reptiles, amphibians, mussels,
birds and mammals by going to the Species List and Critter Sightings sections.
Instructor will: Give the students a couple of example
scenarios. Show students examples of different types of tracks or other
sign. Explain how to tell different types of tracks apart.
Students will: Find sign and write down their account
of what they think happened. Make casts of tracks so they can show
others what they found, or collect scat in plastic bags.
Evaluation: A “show and tell” format will be used to evaluate student knowledge.
Students will demonstrate: Knowledge of nature and basic animal behavior and ecology.
Resources: Lists of common species of mammals, amphibians and reptiles that can be encountered on sandbars are provided on our School Standards page.
