STEM Clusters: Take Three



What do 5 years olds and CEOs have in common? In some cases, both have participated in the Marshmallow challenge!  This week in the STEM cluster How High, How Far, How Fast our 5 and 6 year old students were challenged to build the tallest structure possible using 10 pieces of spaghetti, one foot of masking tape, one foot of string and one marshmallow – the marshmallow, of course, had to remain sturdily on the top!

Students were focused, engaged, curious, frustrated, angry, and hopeful as they worked together to strategize and problem solve. Working together and collaborating was quite a challenge. As to be expected some students quietly gave their suggestions, “That is not possible; it will be too wobbly, let’s try this,” whereas, in another group, I heard a young fellow demand almost in tears, “Hold this; hold this here; do it now, and don’t let go!”

As I noted in an earlier post on STEM Clusters with the older students, what was  most difficult for them was collaborating together, and accepting or acting on the ideas of their classmates. Although frustrated, the older kids were more accepting of each other ideas and were clearly building upon each other’s knowledge in order to yield a unified result. With the little ones, those who were able to work together followed a more step-by-step approach. “I will do this; now you try your idea.” 

In one case, it was clear after the first 10 minutes that a particular youngster was simply unable to work within a group, so the facilitator gave him his materials and asked him to work through the challenge on his own. He was happy to do so; but when he realized help would be necessary, he very politely asked the little girl next to him to assist. Noticing this change I asked him “what was the problem the first time you tried to work together?” He said, “Well, I am the boy, and I told her what to do and she wouldn’t do it.” I responded, “What does being a boy have to do with it?” He said, “Boys are the ones who tell girls what to do, that is the way things always work.” Now, I know the family of this little boy, and I am more than certain that in his household, responsibilities are shared across genders.  So I thought, wow, our society still has a lot of work to do! First through modeling gender-neutral roles, and then by improving how the media, advertising and entertainment present those gender roles.

A lot happened during those 45 minutes, and most groups were satisfied with their hard work and accomplishments. Here are some of their reflections:

“I was thinking like an engineer; trying to imagine a blue print in my head.”
“I liked when we were working together and did not get mad at each other.”
“It was REALLY hard to get that marshmallow to stay on the top!”

Could it be that our students must learn to collaborate before they can fully experience and practice other challenging skills? In other words is collaboration a necessary step onto a ladder of 21st century skills? Or are the 4 C’s spokes on wheel of integrated skills?

STEM Clusters Take Two


For our second round of STEM Clusters, this time for our K-1 students, I have decided, instead of a “quick glimpse” approach, I would spend a full period in each of the 8 sessions. For our youngest students the choices are the following:

Bee Bot Robots
Not a Box
How High, How Far, How Fast
Take It Apart Party
Makey Makey
Legos

Last week I shared my time with our K/1 students participating in “Bee Bots.” Students programmed the little “Bee Bots” or mini Bees acting as a computerized robots, to spell a word through their movements, or move to a programmed destination like a waterfall or a volcano. Students needed to plan out each move, indicate how many spaces, as well as when to turn; they then inputted their plan into the Bee Bot, and watched to see if they were accurate. It was a trial and error process.  Students were also given time to experiment with the Bee Bot App. I wish I had been exposed to introductory programing as a 5 year old!

Not a Box was my destination this week. In this cluster session students were creating and designing anything they wanted from boxes. They were charged with using their imagination, sketching out a design, gathering materials and then coming up with a product. They had plastic saws and hinges to guide the construction; many worked in pairs to problem solve and collaborate. By the end of the session we had: a marble maze, a dressing table and closet, the San Francisco Bay Bridge, and a Shark with all of its parts!  Another afternoon of creativity, design thinking, and play! 


Inaugural Year of STEM Clusters in the Lower School


Clusters are a 60 minute, weekly period, when all of our Lower School students, in mixed-age groups, collaborate together on a project based on a shared interest. Recognizing the national and global STEM initiatives, this year we decided to plan our clusters to expose students to a variety of STEM skills.  Through a “petting zoo” STEM experimentation period, students were exposed to many STEM activities. Based on that experience they chose one of the following STEM activities:

Makey Makey
LittleBits 
Take It Apart Party 
Paper Instruments 
Scratch Programming
First LEGO League 
Cardboard Machines
Rube Goldberg 
How High, How Far, How Fast

During our weekly STEM Cluster time, I would wander from classroom to classroom observing and interacting with each group. At every stop I encountered engaged, curious and hard working students. There was such a desire to accomplish something; students were hyper focused. At times this led to communication difficulties and conflict among group members. I realized how different this type of collaboration was in comparison to your traditional cooperative groups for a subject based class session. It will take some time for teachers to feel comfortable facilitating these sessions and for students to learn together, share with one another, and ultimately arrive at solutions and outcomes in a unified manner. The journey is well worth it! Observing a “water in glasses” concert, understanding the 10 energy steps of Rube using everything from a domino, to foam, plastic and paper tubes, to chairs, tennis balls and different toys, to watching students take-a-part toasters and hard drives, my weekly “glimpse” of STEM Clusters spurred my own learning in new directions.

I want to take the time to thank our Instructional Coach Bree @BreeABerman for all of her planning for, researching, and experimenting with the STEM activities in order for this inaugural year of STEM Clusters in our Lower School to be successful. I also want to thank Sarah for her work in the planning, logistics, and implementation of this new venture.
