Back at the Rio Chama with River Classroom

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.

 

 

April ICU Update

Since the last update, we have released two Desert Cottontails that came in with no injuries, both of the Red-tailed Hawks we’ve had in care, one more Northern Saw-whet Owl, four Rock Pigeons and the Collared Dove. We also released a Cooper’s Hawk who came in with mild head trauma.

Inside, we have eight juvenile Desert Cottontails, one Collared Dove, a fledgling Rock Pigeon, two fledgling House Finches and one nestling House Sparrow. Summer is definitely upon us.

 

Outside we have one last Saw-whet owl, the Black-headed Grosbeak and a Collared Dove. The Saw-whet owl has just passed mouse school with flying colors and will be ready for release in the next few weeks. The Grosbeak is showing some great feather growth and will be ready to go once the Grosbeaks get back from migration.

Thanks to everyone’s support, we are able to take excellent care of all of these critters. We couldn’t do it without YOU!

Blog Under Construction

We apologize for the mess, but we have some exciting news!

Our NMWC blog has become so popular that we are expanding! In the near future, we’ll include more articles about wildlife rehabilitation, animals that we have here at NMWC, and what it’s like to care for education animals.

Please excuse us if things look a little unorganized for a while.

Geology rocks!

For the second week in a row, we had snow on Tuesday! We’re so glad for the water, but our Chama Elementary and Tierra Amarilla Elementary students were again disappointed that we couldn’t go outside for our geology hike.

Since we couldn’t take our students to the rocks, we brought the rocks to our students!

We began by reviewing the three main types of rocks. Students guessed as to what each type could look like. We made a chart with columns for each factor that students felt could help in identification. The last column was their guess as to the type of rock. We also reviewed subjective and objective observations. Students had to include at least one subjective observation and at least one objective observation.

Most students worked in groups, although a few chose to work independently. Each group got through about 15 rocks, and by the end of the exercise, everybody was doing a great job at identifying whether a rock sample was igneous, sedimentary, or metamorphic.

After becoming pros at identifying rocks, we moved on to learn about the Law of Superposition. Next time we talk about this, somebody remind me to bring a layer cake.

Utah Education Network has a fantastic activity for helping kids understand how geologists use rocks to piece together the story of Earth’s history. Our students began by trying to put the “nonsense cards,” which just have seemingly random letters on them, in some kind of order.

We didn’t give our students much information about this, aside from asking them to put the cards in some kind of order. Initially almost everybody tried alphabetical order.

Finally, with a few hints, everybody got it. If the letters represent rock layers, two layers that have the same kind of rock must belong next to each other. Students were also able to use the Law of Superposition to explain which rock layer must be the oldest.

After everybody had discovered the pattern, we played the game again with different cards. This time the cards had different fossils on them. Students again put the cards in order based on the fossils found in each “layer”.

This version of the activity is much more like what geologists do. Their job is to solve the puzzle of what’s happened on Earth in the past.

By the end of this class, all of our students had the same opinion…. geology rocks!

Introducing… Geology!

New Mexico (in general) is a pretty dry place. It seems like most people don’t own rain gear. We seldom have to adjust class for weather. This week was a rare exception- with all of the rain/snow, we had to move our outdoor River Classrooms for our Española 4th-6th graders, our Tierra Amarilla 5th-6th graders, and our Chama 4th-5th graders in to the classroom! Obviously being outside is much more fun than being inside, but we worked hard to come up with a fun activity to make up for it.

We decided to start one of our very favorite topics…. GEOLOGY!

To gauge how much our students understand about geology, we began by talking about the three primary types of rocks- igneous, sedimentary, and metamorphic. As we discussed the different types of rocks, our students created a cool foldable to stick in their science notebooks.

After cutting, gluing, and drawing, our students had a neat way to remember the three types of rocks and the rock cycle.

Next, in order to make this concept stick, we used crayons to model the rock cycle! Students began with crayons with no wrappers. These represented igneous rocks. Students used plastic knives to carefully weather the rocks into sediment.

This sediment was converted into a sedimentary rock by lightly pressing on the sediment to replicate the weight of water on it. Students used even more pressure, as well as body heat to transform their sedimentary rock into a metamorphic rock.

Finally, the most exciting step: melting our “rocks” into “magma” and letting them cool to form “igneous rocks”!

While I’m sure our students would have preferred to be outside, we made lemonade out of lemons and had a lot of fun learning about the rock cycle in all three classes! The best part: now our students have the background knowledge for our next outdoor trip to be a geology hike!

Playing Review Games in Chama

After our really fun review game in Tierra Amarilla, we decided to put our students at Chama Elementary School to the test with a little school district competition!

We asked our Chama students the same questions. They responded in the same way- with each group writing their answer on a white board during the 1-2 minute time allotted.

Our students carefully considered each answer.

Once we mentioned how well our TA students did in answering these questions, our Chama students got a little competitive!

As it turns out, both classes did an excellent job answering all the questions. If we had to pick a winner, I’m not sure we could. It was a tie!
