“If you said it would float, you were absolutely WRONG," their teacher calls out from the front of the room. "So give yourself a round of applause. Fantastic.”

Students start clapping as they look around to see who else made a fantastic wrong guess.

What is going on here? Is this elementary teacher teasing the kids who guessed incorrectly?

Mr. Glen explains. “We celebrate failure,” he says, and he means it. “My students really struggle with failure, and they get upset.” He wanted to help them understand that getting something wrong doesn’t mean we should give up. Failure is an opportunity to learn something they didn't know before.

"So we’re actually going through that, and we live to see another day.”

As a water resources engineer, Julia Kelly spends her days thinking about where water is going. “The whole system of water, people's relationship with water and how they affect each other is fascinating,” she says. But long before she was called upon to predict the flow of stormwater or help plan infrastructure and protect coastlines, Julia was thinking about a water filter design for a plastic frog in her fourth-grade classroom in Fall River, Massachusetts.

In fact, we still have the footage.

Do you remember being a kid on the first day of a new school year? Wearing new clothes, carrying fresh spiral notebooks, finding your seat with a mix of excitement and worries. What are the rules? Will other kids talk to me? What if the work in this class is too hard? What is this year going to be like?

As teachers, we try to ease those worries. We introduce the rules and routines on the first day, but a classroom culture takes more time. Before we can really teach content, we first need to create a classroom where students feel safe asking questions, working together, and learning from mistakes. 

Many educators like to start the year with hands-on STEM. A YES engineering challenge is a shared experience that helps set the tone and establish how this class will work together.  As students learn the Engineering Design Process, they also learn expectations and classroom norms, begin to see themselves as capable problem solvers, and give teachers valuable insight into how their new students think and behave.

“Introducing... the slipper of the century!” a seventh grader gestures towards his teammate, who starts walking down the middle of the classroom wearing one bright red slipper with a neon-yellow strap made from scrap fabric.

The student announcer continues, “We made the Stupendous Street Slipper using recycled cellulose as a base for our outsole…”

Three middle school students are huddled at their table, deep in thought.

“We’re at $7.75,” one student says. “So that’s under $9.00.” They all look at each other.

The medicine cooler they are designing has a maximum budget of $9.00, so there's room if they want to spend a little more to improve the design. After some discussion, they decide to add aluminum foil to the outside of the box for an extra layer of insulation.
