Our 5th and 6th grade students from Tierra Amarilla Elementary have spent the last few months exploring and collecting data from the Rio Chama in Los Ojos. Last week we decided that it was time to head to a tributary of the Rio Chama, so we spent a gorgeous, sunny afternoon exploring the Brazos River.
The first part of the day was spent hiking along the river and comparing the Brazos to the Rio Chama.
We found quite a few differences in the Brazos and the Chama, including the size of the stream, the surrounding vegetation, and the physical characteristics of the stream.
After students had a chance to explore the area, we pulled out our GPS units. Students learned about latitude and longitude the last time we were at Tierra Amarilla Elementary, and this time we moved on to finding our latitude and longitude.
After students reviewed how to find the coordinate for their latitude and longitude, we split up into teams. Each team was tasked with finding something really cool (such as a beehive or an unusual rock). Teams found the coordinate of this item and recorded it on an index card, along with a clue as to what the item was.
Next students learned how to input a waypoint and use the GPS to navigate to that specific waypoint. This took a little trial and error!
Most of the students were able to find their set of coordinates and identify the object for which they were searching!
Understanding how to find a specific location using the GPS is an important skill so that our students can tag our scientific data with the location at which it was collected. Our students are now prepared to do this!
