I meet with more than 100 students per day in my Earth science classes. As a relatively new teacher, I need suggestions on how to get to know them better including learning their names and interests in a timely manner. – L., Connecticut

Students like to know teachers care about and respect them. Knowing their names is important from the start. When I would dutifully call out names on the first day, I predictably mispronounced a few or used a full name rather than a preferred nickname. Although some students found this hilarious, it embarrassed me and other students. So I started asking the students to introduce themselves, allowing me to annotate my list with phonetic spellings and nicknames. Regardless of how you feel about seating charts, I found them helpful at the beginning of the year to connect names and faces.

Identifying their interests can help personalize the science class. During the first week of school, ask students to write down information about themselves on index cards: name, birthday, nickname, interests/hobbies, school-related activities, out-of-school activities, (e.g., community organizations, sports teams, jobs), and other favorites and conversation-starters. I used a different color for each class, and each day I pulled a card and made a point to talk to that student informally. Other ideas from our colleagues:

• Steve Olenchek created a “Sciencebook” page for students to share more information about themselves (the page is similar to a Facebook page). 

• Darci Sosa collects similar information in an online Google Docs survey. The results can be viewed in a spreadsheet. She sorts by any of the columns and uses information to group students with similar responses.

Your initial connections with students can promote participation and create a positive climate for learning.

Upon reflection on last year’s practice of taking children on “nature walks” outside, I see how much they enjoyed nature, made gains in vocabulary and became familiar with diversity in plants. In June, at the end of the school year, I had the occasion to write to the school families about their children’s nature learning from experiences in the tended garden around the building.

Dear families,

Children who had never heard of a Paw paw tree now know where one is located in the Garden and may even recognize the shape of its leaves. This is significant because it represents the many times we’ve run to it, stopped to feel the leaves and notice how they have gotten bigger since last time, and the times we’ve picked leaves up some from the ground and felt the bare twigs and flower buds. The children have become familiar with several other trees (at least with what they can touch at ground level) and other plants by touch and smell. They understand that birds, deer, squirrels, and smaller animals, such as insects, live in the garden. They have learned to touch plants gently so the parts of the plants that are still being used do not get damaged.

The sometimes-on and sometimes-off flow of water from the upper pool source to the “pond” (garden fountain) has challenged them to think about where the water might come from, why it stopped flowing, and what they can do about it. Some children speculated that the rocks in the upper pool are blocking the flow, or maybe too many leaves fell into the water and were excited to share their plans for reestablishing the flow. I wish I could let them try out their ideas for restoring the flow!

There are many ideas we can let them try out. These are questions children asked aloud or through their actions: “Are the peas ready to pick?” “Should I bury the beetle back in the sand where I found it?” What made the holes in the Paw paw leaf?” “How do birds get food from the bird feeder?” “Is that smell coming from the bush?” “What can I hear when I put the shell up to my ear?” “What does clay stick to besides my hands?” “How far will this leaf go when I throw it?” “Which is bigger, this leaf or my shoe?” “What lives under a log?” “How can I pour water into this tube?”

Through their investigations they are building a beginning understanding about plant life cycles, seasonal changes in plant life, the needs of small animals, diversity in plants, the properties of earth materials, and the physics of sound and water flow.

Sharing children’s work with their families strengthens their learning because they have additional opportunities to talk about their ideas and use new vocabulary words. Family members learn how deeply children think about science topics and may more often provide ways for children to try out ideas.

During a nature walk children may learn many new words: cloud cover, leaf, underside, stem, bark, insect, community. Repeating the walk each week gives them opportunities to use that vocabulary again and again, and to see changes in the area of the walk as weather and seasons change. Every early childhood program has some aspect of nature available to observe, talk about, and record. Can you see the sky from your front stoop? Whether you have a patch of grass or a huge field of prairie, your children can use their senses to experience it, describe it and notice weekly changes.

Turning the calendar to the month of August signifies the excitement of another school year. Early on in my teaching career, a colleague jokingly stated when the date stamped on the breakfast orange juice container read August 15 it was a reminder that a new class of students was on the horizon.

Over this summer, many of us have turned to NSTA to elevate our teaching practice. Some have participated in Next Generation Science Standards (NGSS) chats reflecting on the reasoning and thinking children need to exhibit in our classroom, whittled down our “books to read” list by finishing an insightful NSTA Press publication, or attended the STEM Forum & Expo seeking to develop a coherent STEM education strategy for our school or district.

As you embark on a new school year, continue to make the most of your NSTA membership experience by accessing the many quality resources our association offers.  Please also consider enhancing the membership experience for your colleagues by contributing to a favorite resource and sharing your ideas. Your ideas are valued and welcomed.   

I recall many August’s ago sitting in a backyard chair reading NSTA Reports for the first time.  I especially remember the pull-out section and the plethora of opportunities provided in the Freebies for Science Teachers, and In Your Pocket areas.  The grants, awards, fellowships, and competition page also provided me with timely resources to consider.  I encourage you to access and take advantage of these same resources.

Since that particular summer, NSTA has been a trusted source and the first place I turn for opportunities to improve my teaching practice.  My membership experience has enabled me to contribute to our association and brought many new friends for which I am most grateful.  My learning through NSTA via conferences, webinars, books, journals, blogs, and personal conversations with colleagues has been most rewarding.  During the writing of the NGSS, these NSTA learning experiences were invaluable. 

Earlier this summer, I overheard a lively conversation between two beginning teachers having lunch together during the STEM Forum & Expo. Despite them sitting the next table over, their excitement was evident as they shared resources and new learnings with great animation. Each teacher spoke about ideas they planned to implement in their classroom and described new strategies of how they would be engaging students in three dimensional science learning.  Their passion was contagious.

As your professional association, NSTA is uniquely poised to support innovations of the new vision for science education brought forth by the Framework and the NGSS. Continue to engage in the science reform movement as you use and contribute to the resources available through our association. Please consider your commitment to NSTA, and best wishes for professionally rewarding new school year.

Based on Interviews With Professionals Using Science in the Workplace

Paleoseismologists study geologic records to learn about earthquakes that happened thousands of years ago and then use that data to create models to forecast the probability of future earthquakes. 

Paleoseismologist Chris Goldfinger.

“It is a wide-open field,” says Chris Goldfinger, a paleoseismologist at Oregon State

University in Corvallis, “because a lot of cities around the world are sitting on time bombs [active fault lines].”

Work overview.

My job is to assess hazards in fault areas in cities. Cascadia [the Pacific Northwest] is a prime example—no one had any idea there was a gigantic fault below Portland and Seattle, and now no one is sure what to do, because the cost of doing anything is in the billions or trillions of dollars. I look at geologic evidence such as offsets in the ground, landslides, or submarine landslide deposits. I take core samples from such active fault areas as Cascadia or San Andreas in the United States or others in Japan or Sumatra. This “ring of fire” around the Pacific Ocean has the easiest-to-find earthquake signals, which help us understand other fault areas.

I spend a month in the field at a time and collect about 100 core samples. For those deposits triggered by earthquakes, I try to figure out the timing, magnitude, and origin of the quakes. I use that data to build a time-and-space framework showing how a big fault behaved over long periods. The resulting map looks like a flipbook of a region with each frame showing a different earthquake.

To understand the nature of an earthquake threat, we provide a long history so people can know the probabilities and we can better determine our course of action. I use modeling software to estimate dates and to create earthquake-type movement in a representation of the seafloor. Other software simulates the effects of a tsunami moving to land. I model turbidity currents to see where sand will get deposited.

Goldfinger pulls a seafloor core sample from a storage rack in his lab. Photos by Oregon State University.

Training and helping graduate students is a big part of my job. My favorite part of the work is discovering something new and cool. It still amazes me how much you can learn about the big-picture things that happened to the Earth by poking around in dirt. The part I like least is politics. If I discover that a hazard affects people, it instantly becomes political, because developers are now saddled with an earthquake problem.

Career path.

In high school, I saw geology students packing shovels in a station wagon, heading to Death Valley. It looked like fun, and it was stunning to me that you could gain an understanding of what you’re standing on and where mountains came from, just by looking around and observing things. In college, I got a dual degree in geology and oceanography in the mid-1970s. Plate tectonics had just been discovered 10 years earlier, and all the big-picture concepts about the Earth had just come into focus.

After I graduated, I started building a sailboat with the aim of sailing around the world. Then I talked to a neighbor who was doing interesting work in geology, and I decided to go back to geology and combine that with my interests in boats and the sea. When I graduated with my PhD in geology from Oregon State University, the university hired me to work in the school of oceanography, which recently merged with the geology department.

I got interested in studying the past. But I realized that it’s also important to understand what is going on today. That’s why I began studying subduction zone earthquakes and tsunamis.

Knowledge, skills, and training needed.

Paleoseismology is multi-disciplinary and requires a good background in geology and marine geology. The latter is not a subset of regular geology; the principles are very different. For the marine work, it’s good to know about remote sensing, weather, and seamanship, and it’s handy to know how to build instruments and repair things. Because you go out on a big expensive ship with 50 to 70 people at a time, it requires a lot of teamwork and logistics.

Advice for students.

Get a broad grounding in all the necessary subjects. Gain some computer skills also.

Exploring Science and History With the Library of Congress.

In 1869, 25-year-old Swiss physician Friedrich Miescher first identified and isolated deoxyribonucleic acid (DNA), calling it nuclein. Decades later, scientists identified the DNA molecule’s role in determining genetic inheritance. But not until 1953 was DNA’s distinctive double-helix structure discovered by James Watson and Francis Crick. Working at the Cavendish Laboratory at Cambridge University, they used tools as simple as pencil sketches and handmade physical models to form their ideas.

In his 1988 book, What Mad Pursuit, Crick explained: “Our first attempt at a model was a fiasco.” But later models and sketches,

The double-helix sketch.

including the one shown here, helped them visualize possibilities and test solutions, which led to demonstrations, illustrations, and diagrams through which they shared their findings with others.

One such diagram appeared in a 1953 article in Nature in which the two young scientists (Watson, 23, and Crick, 35) announced: “We wish to suggest a structure for the salt of [DNA]. This structure has novel features which are of considerable biological interest.”

Stating that their model was “radically different” from those proposed by other scientists, Watson and Crick described DNA’s structure as a double helix with the bases pointing in and forming pairs of adenine (A) with thymine (T), and cytosine (C) with guanine (G). The small, “purely diagrammatic” figure that they included (drawn by Crick’s wife, Odile, and similar to the pencil sketch), showed how the components of DNA fit together.

They acknowledged the need for more experimental data and asserted, “It has not escaped our notice that the specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material.”

They were right. Knowing the structure of DNA is, in fact, the key to understanding how genetic information is copied and passed along to future generations.

I just took a fifth-grade position, and the principal showed me the classroom I’ll have. It’s a brand-new building, and there’s nothing in the classroom—just the student tables, bare bulletin boards, a few empty bookshelves, and a teacher desk. When I was student teaching, the classrooms had lots of interesting bulletin boards and centers, but this is really barren. What can I do in a short time and with a small budget? —A., California

New teachers should realize the classroom displays and bulletin boards in the classrooms of veteran teachers are the result of many years of experience and collecting. But starting with a blank space can be good—you won’t have to go through someone else’s “stuff.”

Imagine how you want the room to look and feel. Remember that less is more and avoid covering every available space and filling every nook and cranny. Students should be able to focus on their work, and some classrooms are so cluttered it’s distracting.

I can’t speak for the other subjects you’ll teach, but for science there are a few quick things you can do to make the classroom attractive and conducive to learning:

• Use some shelf space for a classroom library with books on a variety of nonfiction topics and reading levels. Start with books from the school library and supplement with books from yard sales or children’s book sales during the year.
• Reserve and label a place in the room as a “science center” with materials for activities related to what students are currently learning. This science interest center could also have objects or materials for students to explore (e.g., shell collections, animal bones, rock samples, weather maps, simple machines). Students may enjoy adding to your collection throughout the year. Change the materials with each unit of study. Any science-specific safety equipment (such as goggles or aprons) could also be stored here.
• Add a few plants (live or artificial) to the room.
• Find out what technology will be available in the classroom—laptops, tablets, etc. You’ll need a place to store these, close to outlets where they can be recharged.
• Set up a private study center for students doing make-up work and independent study or who need fewer distractions. You’ll probably want to have other areas for small group instruction and project work.
• Invest in some plastic tubs to organize materials and keep them out of the way.
• Although it’s not part of the décor, find out what safety equipment and science materials will eventually be in the classroom.

In terms of bulletin boards…

You can spend lots of time and money on elaborate bulletin ones, but that is not really necessary! I found that the most effective bulletin boards were those created with student materials (or by the students themselves) and whose content served an instructional purpose:

• Include a “word wall” with the key vocabulary for each subject. Start with a blank space and as you introduce a new term, ask a student to create a card with the word and post it on the wall. Refer to it often during class discussions or writing assignments. The cards can be taken down and used during review games, too.
• Safety rules should be posted in a prominent (and permanent) place. During the first few weeks of school, students could make the posters for display here.
• Reserve some space to display student work.
• Maps from a travel club cover a lot of bulletin board territory. A state map can fit into science, social studies, and math activities.
• Print magazines and the Internet are great sources for pictures related to your current units. In addition to their decorative value, these pictures can be used to stimulate discussions or as part of writing prompts.
• Set up a space for a photo gallery. Display some of your own photographs related to a topic and encourage students to share their photos or bring in related pictures or news articles. Post photos of students engaged in your class activities.

I know experienced teachers who deliberately start each year with blank walls or bulletin boards. As the year progresses, students add their own artifacts to the classroom.

As a beginning teacher, you’ll have to prioritize your time. The bottom line is that the learning activities you and the students do are more important than elaborate teacher-created bulletin boards and other decorations.
