It’s the journey, not the destination

It’s the journey, not the destination

Last week I was able to get outside, even with the new snow that came. Kindergarten students had been exploring the concept of rolling and the properties of the objects that are ‘good’ rollers. After discovering that the crayon and vial (both cylinders) didn’t roll well, we decided to see if they would roll well on the hills around our school. We tried the sidewalk that is sloped, an asphalt path, and hills of different sizes that were covered in snow and ice. Finally, we made it to the playground and tried these objects on the slides as well. We had discussed before heading out to watch for rolling versus sliding. We discovered some hills made things roll better, but in an unexpected direction – the slope was a different direction than anticipated. We also discovered that bumpy hills don’t make good hills for rolling. Finally, the slides taught us that it’s possible to have too big of a hill and that’s when things start to slide instead of roll but sometimes it does both on the same slide.

This was the first time trying this lesson and I was a bit nervous about how things would go. This age group is a bit of a wild card to begin with, add to that the fact that we are on the playground to do our testing and observing created a potential for a free for all. I was pleased to observe kids actually doing what they were supposed to. Sure, there were a few who ditched their partner and spent time going down the slides themselves, but in the end most students had observations to share. One of the other things I noticed was the enthusiasm of their observations. Again, this might have to do with the grade level but many students had high energy, vocal and theatrical descriptions of the motion of the crayon and vial. This served as another good reminder for me to trust myself and trust outside learning. Even if nothing had worked, kids were still outside, playing close attention, sharing observations and working together.

Rolling

Last week, I also took  two fifth grade classes on the extended walk to the local park we had visited this fall. Part of the intent of this visit was for the class to see an example of a nature playground to help inspire ideas for the design project they have been working on. Along the way, our goal was to also observe seasonal changes to the forest – what has stayed the same and changed since our last visit in September. Finally, the next science unit is Earth Processes and we were searching for evidence of erosion. The temperature was hovering right around zero before we left  (the magic number for canceling outdoor activities according to school policy) but since it was 3 and the forecast to only get warmer we got the green light. It was simply a glorious morning. The sun was out for our first half. The sidewalk was actually our most treacherous walk with ice left over from shoveling and melting. But once we got into the woods it felt a bit like a Robert Frost Poem, only during the day, and for a brief few moments, everyone stopped to listen

“The only other sound’s the sweep

Of easy wind and downy flake. “

On we walked, checking for tracks, listening to the wind, watching for birds, surprised by the whiteness, noticing things we didn’t notice when the world was green.  Yes, we made the observations I had planned, but I was reminded again that sometimes its not about the destination but the journey.

Two weeks ago, a second grade class I work with was curious about the bumps they had noticed on the stems of some plants around our gardens. The bumps the kids notice are called galls and are a growth on the stem of goldenrod plants. A fly lays an egg that makes it way into the stem and causes to plant to produce a growth hormone forming a lump around the larva that forms. This lump also provides a safe place for the the larva to spend the winter. When spring comes, the larva will transform into a pupa, then emerge as an adult Gall Fly to start the life cycle again.

The teacher had asked me advice about opening the galls and what kind of investigations we could do. This is one of the favorite parts of my job. I strongly believe in the power of student generated questions and am always thrilled when a classroom teacher not only takes time to have students generate their own questions, but finds ways to have students answer their questions. This question also happen to come up when I friend I work with on the Minnesota Science Teachers Association board had been posting about his ecology class collecting galls for their investigation: What is the relationship between gall size and the type of insect that lives inside it? So now, not only did we have second graders ready to find out the answer to their own question, but we had an audience to share our answers with.

After measuring the diameter and mass of each gall, we got the most exciting part, cutting it open! It felt a bit like a birthday party, lots of excitement and impatience; ‘Open mine, open mine!” We discovered three different outcomes from our opening, most students had a tear-dropped shaped white larva (a gall fly larva); a few students had more of a worm like white larva (beetle) and two students were crestfallen to discover their gall was empty.  While an empty gall was certainly disappointing, it led to a good conversation about data and how even zeros are numbers that count and still tell us information.

Data was entered on a shared spreadsheet to compare our findings. A mutual time between our two schools was scheduled and the next thing I knew we had a Google Hangout going. Second graders were ‘face to face’, so to speak, with high school seniors who had done the same investigation. My students wanted to know how big their prairie was, what colors their galls were, how many doubles they had and if we could go visit them. While we won’t be planning a field trip anytime soon, I feel confident I’ll be looking for future connections I can make to collaborate, communicate and connect.

Unexpected Results

Last week, unseasonably warm temperatures (or is this the new norm?) inspired me to think twice about an upcoming scheduled lesson. I was feeling inspired to try something new and recent conversations had reminded me to consider how to bring outdoor learning into this lesson. I discovered an app called Audioworks https://itunes.apple.com/us/app/audioworks/id943541587?mt=8 that let students ‘see’ the sound created from different sources. This was a perfect opportunity for students to experience the abstract nature of sound waves with a live streaming image. Based on previous success of having students create listening maps, I thought I could bring students out and we could both listen AND see what these sounds were like. Luckily, I work with some pretty flexible colleagues who were willing to divide up our tasks. Half of the class stayed inside, exploring how pitch was created with a variety of instruments on loan from the music teacher. The inside group also got to experiment with chrome music lab https://musiclab.chromeexperiments.com/Experiments

I took the other half of the students out to the hall. I showed the app, demonstrated what it could do and  explained my idea for recording sounds. I also let them know I had no idea if it would work or not and asked if they would be willing to experiment with me and test it out – they all were perfectly willing. It became pretty clear right away it was too quiet at this time of year to hear much. But, I showed them their boundaries for exploring and asked them to figure it out.

While the few crows that were about were too far away to catch on the microphone students made all sorts of other discoveries. When you rattle the leaves of the grasses it makes a swishy sound that shows up as long, fat waves. When the flag pole pulley hits the pole, it’s tall, spiky and very thin. Students found sticks to bang on different materials, rocks to clank, stomped their feet, broke branches, rubbed the ipad up and down their coats.

So we didn’t catch the sounds I expected, but we all learned something. Kids still got to ‘see’ sounds from different sources, make observations and comparisons. In addition, students had the freedom to make their own discoveries and were active in their learning. I was reminded that it’s ok to not have everything figured out and that kids are ok trying out new ideas with you. I was reminded also to trust nature, even when things don’t work out, they work out.
