Acorns for fun in science

By Peggy Ashbrook

Posted on 2018-11-03

Acorns scattered on the ground.

Chinquapin oak acorns, also spelled “Chinkapin.”

This fall there are an abundance of acorns falling from the oak trees in my area. Scientists study oak trees to understand possible reasons why some years larger amounts of acorns are produced than others. 

Acorns are free material for early childhood science explorations, with permission from the landowners. A nature walk among trees exposes children to new vocabulary in a meaningful context. “For example, as they learn the word acorn, they also learn that a variety of adjectives such as dark, ripe, rotten, and elliptical are suitable when providing detailed observations” (Arreguin-Anderson, Alanis, and Gonzalez).

The shapes of acorns vary from one oak species to another (see identification resources below) and make a wonderful addition to a sensory table (as long as your children are older than 3 years and are not putting objects in their mouths). After several weeks children may notice holes in the acorns and discover the tiny grub or caterpillar-like animals that emerged from the acorns. These are baby insects, acorn weevils, and provide an opportunity to wonder at this specific relationship of plant and animal.

As children use acorns at the sensory table, or as game pieces, in imaginative play, and in art explorations they will notice and sort acorns by attributes such as size, shininess, or the texture of the cup (“hat”). 

Acorns roll but not in the same way as marbles—something to discover when setting up ramps for rolling. Spinning an acorn is easier when a stem is added to make it into a spinning top. Make a hole by pushing a nail or awl into the top after the cup is removed, on the opposite side from the small point on the bottom. It is easier to poke a hole in the tops of some acorns than others. 

Do all acorns float? Or do they sink? The cupula or cup of an acorn makes a tiny boat. 

You might find that some of the acorns you gather are already growing a root. Plant them in soil to grow a tree or put them into a clear container or bag to watch the root and sprout growth.

Read about the way other educators engaged children in examining acorns in these two articles from Science and Children:

News Roundup banner

This week in education news, fewer foreign students are choosing to study at U.S. universities; Alaska school district grows fresh food for school lunch program and supports local employment; Missouri Governor signs STEM education and computer science bill; to become readers, kids need to learn how the words they know how to say connect to print on the page; new analysis unveils that several states don’t consider teacher effectiveness in layoffs; and school leaders must create schools that empower teachers to grow and have meaningful collaboration.

Why Foreign Students Diverting From America Is A Problem

All the media attention these days around global trade tensions is missing a potentially longer-lasting looming danger to U.S. competitiveness: Fewer of the world’s “best and brightest” are choosing to study at U.S. universities. Read the article featured in Forbes magazine.

Alaska School District Grows Fresh Food And Supports Local Employment

At a few remote Alaska schools, produce ranging from tomatoes and squash to bok choy and cilantro is grown in greenhouses heated by wood-fired boilers. This provides fresh greens and vegetables for the school lunch program in communities where some residents have to drive two hours, one way, to the nearest grocery store. Southeast Island School District’s initiative has also increased employment for the remote communities it serves on Prince of Wales Island. The district hires local citizens and high school students to stoke the boilers during the long winter months. Read the article featured in District Administration.

Parson Signs STEM Education And Computer Science Bill

On Tuesday, Missouri Governor Mike Parson signed into law House Bill 3 at Grand Center Arts Academy in St. Louis and at Poplar Bluff High School in Poplar Bluff. Passed during a special legislative session called by the Governor in September, HB 3 deals with computer science, expanding course opportunities for high school students, creating a certification process for teachers, establishing a fund for any future public and private financial support, and developing curriculum standards.

Tell Washington And The Universities That Innovation Takes More Than STEM

Presidents and professors, business leaders and tech billionaires have all stressed the need for innovation. They are right. Especially in a globalized world, this country needs to innovate continually in order to compete and maintain high living standards. These advocates almost always also claim that the innovation effort depends on getting more people into STEM subjects. In this, they are only partially right. STEM is necessary for innovation but seldom sufficient. Read the article featured in Forbes magazine.

Why Are We Still Teaching Reading The Wrong Way?

Our children aren’t being taught to read in ways that line up with what scientists have discovered about how people actually learn. It’s a problem that has been hiding in plain sight for decades. Read the article featured in The New York Times.

NCTQ: Many States Don’t Consider Teacher Effectiveness In Layoffs, Dismissals

Fewer than half of states require school districts to use teacher effectiveness data in decisions to dismiss teachers or issue layoffs, according to a new analysis by the National Council on Teacher Quality. Read the brief featured in Education DIVE.

Can We Design Schools Where Teachers And Students Thrive?

In order to fully support teachers as they mold students into tomorrow’s innovators, school leaders must create schools that empower teachers to grow and have meaningful collaboration, according to a new report from 100Kin10. Read the article featured in eSchool News.

In America’s Science Classroom, The Creep Of Climate Skepticism

Steve Vernon lives with his wife in a meticulously manicured country club community secured by watchmen in guard booths. He is also a leader of the Florida Citizens’ Alliance, a conservative, 20,000-member organization based in Naples that spearheaded a successful grassroots effort last year to pass the nation’s first state bill allowing residents to demand a public hearing on local school textbooks. With its passage, parents of students — as well as anyone living in a given district — can challenge the books a school is using to teach their community’s children. It was a seemingly parochial piece of civic legislation, but it was one with potentially great implications for science education in the United States. Read the article featured in Undark magazine.

New Report Says ‘Citizen Science’ Can Support Both Science Learning and Research Goals; Inequities In Education, Opportunities, And Resources Must Be Addressed To Meet Participants’ Learning Demands

Scientific research that involves nonscientists contributing to research processes – also known as ‘citizen science’ – supports participants’ learning, engages the public in science, contributes to community scientific literacy, and can serve as a valuable tool to facilitate larger scale research, says a new report from the National Academies of Sciences, Engineering, and Medicine. Read the press release by the National Academies.

The Importance Of Choice In PD

Despite coming to the profession with possible natural instinct and high-quality learning from their teacher programs, our most talented and dedicated teachers starve without continued education. Learning is their fuel. Read the article featured in Edutopia.

Helping Students Develop Perseverance

By Debra Shapiro

Posted on 2018-11-02

Tom Meagher, district STEM education coordinator for Owatonna Public Schools in Owatonna, Minnesota, shows students how to hold a Monarch butterfly before releasing it. “Finding, collecting, feeding, cleaning, and releasing live Monarch butterflies teaches students about scientific observation, collecting samples, recording changes over time, life cycles, and stewardship. Each step requires practice in perseverance,” he says. Photo courtesy of Dani Rypka

While some people use the terms “perseverance” and “grit” interchangeably, David Upegui, science teacher at Central Falls High School in Central Falls, Rhode Island, has a different view: “I am extremely fortunate to work in Central Falls (the most economically disadvantaged city in Rhode Island), where I teach some of the best students in our country. I have several strategies that I have [used] in the past, and also some potential warnings about the use of the ‘grit’ concept (perseverance is much better).”

With “100% of students [at my school] receiving free or reduced-price lunch,” 80% Latino, and many the children of immigrants, Upegui maintains, “all the students are already ‘gritty.’ They’re survivors. That these students show up [at school] at all is amazing.”

Perseverance, however, “is having the faculty to look at academic challenges as a way to grow personally and gain power over the world,” says Upegui. In his classes, “students feel science is our language and knowledge…and a tool for empowerment. They understand that science can teach you how to question the world, and you can apply it to all aspects of your life. My students realize it’s not about one assignment or one test: It’s about tools to help them change the world.” Science, he emphasizes to students, “has built into it the ability of changing. Science isn’t static.”

Helping students persevere is “not training [them] to be managed by others, but to manage others, to be leaders,” Upegui asserts. Because many of his students “don’t see themselves in college, [they] need to be trained to be problem solvers and better citizens,” he says.

Upegui shares stories about the successes of former students, many of whom accomplished goals they once thought unimaginable including attending “Harvard, MIT, the Naval Academy.” He talks about scientists who overcame obstacles, such as Lynn Margulis, who was honored for her seminal work in endosymbiosis. “She was rejected 18 times until her research was published,” Upegui relates. “[I emphasize that] perseverance is something we all can develop: Work hard and work smart.”

Because some of his students are skeptical about their potential for success, Upegui says he carefully scaffolds challenging tasks “to help students have small successes first. I make them challenging enough so it’s interesting, but simple enough to be doable…

“When students work with [one another], they learn to rely on [one another] in a learning community. The students feel, ‘The responsibility to succeed is on all of us.’ Purposeful grouping and peer-editing assignments” can bolster that feeling, Upegui explains.

Dave Carlgren, physical science teacher at Renert School in Calgary, Canada, and his colleagues are taking perseverance through collaboration a step further. “Our science department is looking at a new evaluation strategy that involves students’ individual assessments also counting toward a ‘pod’ mark involving the individual marks of others. In this way, subcommunities of individuals may form that ‘look out’ for…one another. They can help other students in their pod study and prepare to do well,” he explains.

This idea came about because “we see a disconnect between what’s done in school and the way the world is,” says Carlgren. Often in the workforce, people “collaborate in support and aren’t competitive. We wanted to reflect this in classroom assessment and evaluation.”

Beginning this year in fourth- and fifth-grade physical science classes, students have been grouped into pods of four to five students for collaboration. This pod size is “large enough that there’s a significant impact of [grade] averaging, but not too large so that students can easily help one another,” Carlgren points out.

Grouping is based on teachers’ knowledge of students’ strengths and weaknesses. “We teach students over multiple years,” he notes, so teachers have had sufficient time to familiarize themselves with their students’ habits. Other factors in grouping are student communication modes, parental support, past success in science, students’ friends, homerooms, and “how often students will see one another during the school day, the more, the better,” Carlgren relates. Pods can change during the year, if needed, he adds.

“The pod effect” occurs “before the test or quiz,” says Carlgren. High achievers benefit from teaching the material to their peers, while struggling students “will have several students in their pod who can help them and provide different perspectives,” he reports.

Carlgren and his colleagues hope the pod arrangement also will discourage bullying. “We’re pushing the idea that all students have strengths. The pods allow students to focus on the academic side; we encourage them to help the bully and the bullied,” he explains.

So far, students have been “extremely supportive” of the pod concept and of their pod members, says Carlgren. By the end of the school year, the science department hopes to have this strategy incorporated in science classes in grades 4–9. “We hope students will become accustomed to helping others,” he observes.

The Power of ‘Yet’

Tom Meagher, district STEM (science, technology, engineering, and math) education coordinator for Owatonna Public Schools in Owatonna, Minnesota, works closely with more than 120 teachers to design and implement STEM lessons “grounded in [a] growth mindset [and] perseverance…When you approach learning through problem solving, teamwork, and challenges, there’s a whole different mindset: ‘We’re going to solve this together.’”

When describing strategies for encouraging perseverance, Meagher points to Stanford University psychologist Carol Dweck’s work on growth mindset and her TED Talk, The Power of Yet. “When a student says, ‘I don’t get it,’ the teacher responds, ‘You don’t get it yet. What’s our next step?’,” he explains. “This provides a path to grow and expand their knowledge. I find it helps with our teachers, too,…to help them grow out of their own comfort zones.”
To help students develop perseverance, Meagher discourages teachers from “labeling students according to how they perform on tests. Life’s not a race.” Developing student perseverance begins with teachers recognizing, for example, that for a kindergartener to successfully do leaf rubbings and find and sort leaves, “fine motor skills are needed. Some students aren’t experienced in this, so we need to teach them the fine motor skills, plus [things like] sorting and identification,” he maintains.

Often students who are used to getting things right the first time need help developing perseverance, Meagher observes. “They had to learn to change the way they think. [The less-gifted] students were more diligent, more strategic problem solvers.” He found pairing the two types helped the advanced students learn perseverance and allowed the less-gifted students to get help with reading.

Meagher also advises, “Don’t give students specific roles in groups, like notetaker. Just give them the assignment and say, ‘It’s up to you to figure it out.’ They will determine their roles [naturally].” Educators need only step in “when strong personalities are involved,” he suggests.

Rather than presenting challenges to students as things to work on, Meagher suggests teachers present challenges as opportunities for practice. “Students see this as building skill,” he explains.
