The Fall semester flew by, and all four of our River Classroom groups have done wonderfully! Check out these photos of what we’ve been up to.
Our students have had many opportunities to learn how to use a microscope and to examine benthic macroinvertebrates in detail.
We’ve spent a lot more time on benthic macroinvertebrates this year than in the past, and our students have become experts! In December we also began learning about the water quality parameters that we will be measuring in the spring. Students made a wheel of water quality parameters to help them learn complicated terms like turbidity, conductivity, and pH.
Our Chama students got a very special treat- we visited the water treatment plant and the brand new wastewater treatment plant! The professionals who work at these places measure water quality every single day to make sure that the Village of Chama has safe water to drink.
Our middle and high school group from Espanola has done a great deal of data collection while exploring new places this fall.
The school year is off to a great start, and we can’t wait to see what the spring holds for our brilliant, adventurous students!
Fall is here at last, and that means that River Classroom has begun again! This is our 6th year of River Classroom, and so far we are working with some fantastic groups. These include the Española Public School District’s GATE students in 4th-6th grade and 7th-10th grade, the 4th-5th grades from Chama Elementary, and the 5th-6th grades from Tierra Amarilla Elementary.
We began honing our skills as scientists by doing some very close observation of limes. Groups of students selected a lime, recorded observations about the lime, and then had to select their lime from a pile.
We also like to begin the year by doing some initial exploration of the ecosystem that we will be studying, so we handed out waders to test the waters of the Rio Chama.
Two of the groups got up close and personal with some of the local inhabitants.
The year is off to a great start, and we couldn’t be more thrilled with these amazing groups of kids. We’re going to have a great time exploring the beautiful habitats of New Mexico, and we’ll be collecting data and learning science along the way! Don’t forget to “follow” our blog to stay up-to-date on the latest.
Earlier this week our 7th-10th graders from the Española Public School District took advantage of the gorgeous spring weather and ventured out to Pilar, New Mexico to explore a bosque ecosystem along the Rio Grande.
The bosque of the Rio Grande is a lovely and unique environment that encompasses the riparian forest and floodplain around the river. Willows and cottonwood trees are common native vegetation, although invasive tamarisk has taken over in many areas.
We began the day with some time to explore and take notes about this ecosystem and its characteristics.
Students practiced making objective observations of several trees in the bosque.
Because of the recent warm temperatures and melting snowpack, the Rio Grande is running pretty high. The nearest stream gauge reported a discharge of around 1200 cfs, and the water level had been steadily rising.
After a quick lunch break, students hiked up to a bench in the Rio Grande Gorge. From this perspective we had a fantastic view of the bosque ecosystem, as well as the rocks that surrounded us. We discussed the geology of the area and the Rio Grande Rift.
After all of this exploring, we needed a break in the shade. We took advantage of one of the gorgeous group shelters in the new Rio Grande del Norte National Monument to rest in the shade and fill out our ecosystem worksheet. We spent some time comparing this ecosystem to the others we’ve visited.
We had a fantastic trip, and our students now understand a great deal about the bosque ecosystem. Next month we’ll be on to a different location!
River Classroom is a year-long project. We cover so much material, and every once in a while it’s nice to take a look back at the progress we’ve made. We’ve been doing just that in several of our classes for the last few weeks. What better way to see how much our students have learned than a trivia game?
Our 5th and 6th grade students at Tierra Amarilla Elementary really love competition. Our little trivia game brought out the brains of all of our students to prove just how much they remember of what we’ve covered this year.
Students were divided into teams. Each team got a white board, an eraser, and a marker. We kept score on the class board as teams had between 1 and 2 minutes to answer each question and write their answer on their team board.
Our students really enjoyed this game!
As usual we were incredibly impressed at how much our students remembered. From benthic macroinvertebrates to the water cycle to parts of an atom, our students can explain a great deal of science!
With the rapidly approaching spring melt, we are getting our classrooms out into the river as much as possible. Last Wednesday our 4th-6th graders from Española braved chilly temperatures to collect some data on the Rio Chama below Abiquiu Dam.
In our last session our students learned a new equation:
(distance = rate × time)
Our goal for this session was to find the rate/velocity of the Rio Chama. We began by reviewing this equation and talking about different units. This discussion helped us determine which units of measure would be appropriate for measuring the speed of the river. We settled on meters per second, but our tape measures didn’t have metric units, so we had to measure in feet and convert to meters.
Our clever students were able to puzzle out how we could measure the speed of the river with this equation- we could lay out a distance and measure the speed of a floating object! We decided to use an orange. They float well, and they’re so bright that they’re easily visible for catching.
Fortunately, we had a data sheet ready to collect this very data.
Students used rocks to delineate the beginning and end of their river segments.
We had two data collection teams. Each team had 5 jobs. One person released the orange into the river, one person timed it with a stopwatch and recorded the data, one person was responsible for catching the orange with a net, and two people were responsible for making sure the orange was released and caught at precisely the right spot.
We also talked about possible sources of error. Students were concerned about the exact way in which the orange was released. We tried to standardize the way we did this.
Catching the orange was not always an easy task, but our students did a great job!
At the end of class, one of our favorite game wardens dropped by! The students were excited to show off their data and explain what they were measuring and why.
We’re so proud of our students for braving cold water temperatures to collect this data. Everybody seemed to have a great time. The next time we meet, we’ll plot this data and compare it with the measurements we took a few years ago.
The holidays are quickly approaching, and this week we wrapped up our final River Classroom session before the winter break. Our 4th-6th grade students from the Española Public School District met at NMWC to present some fantastic projects and review everything we’ve learned this fall.
Students have been working on individual projects about elements on the Periodic Table. Many students opted to study fireworks and how different elements produce different colors. The chemistry of fireworks is a really interesting topic that fits right in with our lesson on elements in the Periodic Table, and students gave some really entertaining and informative presentations!
After each student had a chance to present his or her project, we moved on to our main attraction: a Jeopardy-style game in which teams of students answer questions related to the material we’ve covered this year!
One of our most important rules: each team must come to a consensus before one group member can raise a hand to answer the question.
We tested the speed of students’ reflexes as they raced to raise their hands after the Jeopardy theme song stopped!
Our students did a fantastic job and successfully answered almost every single question.
For Final Jeopardy the rules changed slightly, and each team had to make a bet for the number of points they could win or lose on each question. Teams had one minute to write their answer to earn their points!
In the end everybody in the room proved to be a brilliant scientist and remembered a great deal of what we covered during the year, so everybody won a mini Snickers bar.
We also took a minute to recognize our fearless leader, Katherine. She founded the River Classroom program, and in the last five years she has made a tremendous impact on many students in northern New Mexico. At the end of this year, Katherine will begin a well-deserved retirement, but we are very grateful for her leadership and influence!
Have a safe, happy holiday, and we look forward to resuming classes in 2017!
