Watching children and teenagers use computers, tablets, and smartphones, it’s easy to assume that these digital natives are very familiar with all of the new technologies. I’ve found that while they know what relates to their interests, many students are unaware of the full range of capabilities of their technology as learning tools. As the editor notes, many technological innovations have the potential to transform education. The featured articles in this issue describe some innovative ways teachers and students are using technology in science classrooms.
Gathering information used to take a lot of time and effort, but today that information is at our fingertips. So helping students evaluate sources and interpret information becomes more important. And students are no longer limited to sharing information through traditional “reports.” The authors of two articles share their experiences in helping students develop information and media literacy by researching information and creating graphic representations and summaries. They also share resources for creating them.

• Science News Infographics describes how to do a visual read-aloud/think-aloud in which the teacher models how to interpret and question an infographic (the authors include several sources for these, in addition to other news services). The article also describes how to guide students in designing their own infographics, with examples of student projects.
• Using Infographics in the Science Classroom* includes several activities in which students analyze infographics that they find and create their own infographics on class topics. The author notes that students were intrigued by the blending of science, data visiualization, and art into a product that could be easily revised and adapted.
• If you’re looking for topics that could be discusses in infographics, see The Gray Wolf: A Good Case Study or Teens and STDs* in this issue. [SciLinks: Wolf, Wolf Population] [SciLinks: Sexually Transmitted Diseases]

Pinpointing Watershed Pollution on a Virtual Globe* has a 5E lesson that involves students in a study of their local environment. Using Google Earth and other sources, students make predictions, evaluate data, and develop inferences. [SciLinks: Watersheds]
There’s an App for That isn’t just a catchy phrase in advertising. This article is NOT a list of apps to download. The authors describe a project in which students actually designed and produced their own apps based on class topics. It’s not as complicated as it sounds—the article has a list of app design software, a rubric, and a discussion of the value of doing such a project in terms of engineering design and media literacy. What better way to understand apps than to create them yourself!
What if you could transform the traditional written lab report into a product that is engaging for both students and teachers? A New Take on Student Lab Reports describes a study in which the authors investigated the use of screencasts in which students do voice-overs of computer-based data collected during labs. They concluded that “regardless of demonstrated writing ability, students can produce clear, articulate, and careful oral explanations.” There are links to a sample student screencast and screencasting software.
The giant tomes that students carry around (and whose costs keep rising) may be a thing of the past. Textbooks 2.0 discusses digital textbooks such as the new e-Books from NSTA. Digital “textbooks” go beyond static text to include video clips, animations, simulations, online quizzes with feedback, notetaking and highlighting tools, and links to discussion forums.
*Don’t forget to look at the Connections for this issue (March 2014). Even if the article does not quite fit with your lesson agenda, this resource has ideas for handouts, background information sheets, data sheets, rubrics, etc.

“Should schools charge more money for ‘unhealthy’ foods?” “Should animals perform in circuses?” Should rare Earth elements be mined in the United States?” “Should prescription drugs be advertised directly to consumers?”
In It’s Debatable! Using Socioscientific Issues to Develop Scientific Literacy, authors Dana L. Zeidler and Sami Kahn present a persuasive case for connecting science lessons to real-world questions and issues like these. Seven classroom units give students practice in the research, analysis, and argumentation necessary to grapple with difficult questions and build scientific literacy.
Today’s students need to be “science literate” in order to contend with these issues, but what exactly does that mean? More than simply knowing the content included in our science standards, our students need to be able to synthesize, analyze, and deliberate over complex socioscientific issues (SSI) which will demand their attention, their input, and perhaps, their vote.
As the authors explain, “As science educators, we do not have a choice but to move our curricula into a new era of contextualized science; our students want to have a say in local and global issues and with their unbridled access to information, they need to be able to identify the positions and motivations of various stakeholders. They also need to be well versed in analyzing the quality of information they receive, including the difference between science and pseudoscience.”
Constructing an SSI unit may seem daunting at first, but the authors suggest that teachers start by adding SSI lessons to already-existing units. For example, if you are doing a unit on the human body, consider incorporating research on a related controversial issue such as, “Should fluoride be added to drinking water?” or “Should fried foods be banned?”
To help facilitate the process, the authors have identified some steps that are useful in guiding teachers through the development and implementation of SSI in their classrooms:

1. Identify Topics. Review newspapers, books, internet sources, professional science education-related journals, and television/movies for current issues related to your subject matter and course objectives.
2. Collect Resources. Look for a range of sources reflecting a diversity of viewpoints.
3. Introduce Topic. Engage students with magazine headlines, articles, advertisements, YouTube videos, photos, models, or other media.
4. Prepare Students for Discussions. Set ground rules for class discussions, emphasizing the value of all ideas, mutual respect for participants, and intolerance for mockery or personal attacks.
5. Pose Controversial Questions. Introduce contentious questions (e.g., “Should schools charge a ‘fat tax’ for unhealthy foods?”) and challenge “common knowledge” of subject matter (e.g., Are calories from fat different than calories from sugar?”).
6. Provide Formal Instruction. Present subject matter in a variety of ways (e.g., direct teaching, laboratory investigations, internet/textbook research, class discussions, guest speakers, field trips, films) to ensure content coverage and student engagement.
7. Incorporate Group Activities. Allow students to investigate issues in small groups, emphasizing the analysis of evidence, reinforcement of content matter, monitoring of understanding, consideration of divergent viewpoints, and full participation of all students.
8. Provide Guidance in Evaluating Primary and Secondary Sources. Discuss the importance of identifying bias and provide tools for assessing trustworthiness of research sources.
9. Assess Knowledge and Reasoning. A variety of “products” that allow students to demonstrate learning can be developed. Assessment should include content understanding as well as its reasoned applications to the issue at hand.
10. Have fun! SSI provides opportunities for creativity, engagement, and exploration by students and teachers.

Science, technology, engineering, and math (STEM) hold tremendous interest for students at all grade levels. The breadth of the topic areas teachers can cover in STEM lessons reinforces for students that these fields are interconnected and linked to exciting scientific and technical developments that are key to our future. The March 2014 issue of NSTA’s Book Beat highlights strong STEM lessons that connect with the Next Generation Science Standards and Common Core State Standards.
Doing Good Science in Middle School, Expanded 2nd Edition: A Practical STEM Guide
Olaf Jorgenson and his coauthors took middle-school science teaching by storm when NSTA Press published the first edition of Doing Good Science in Middle School. Teachers loved the down-to-earth advice and lively lessons in the book and propelled the book to the top of the Science Store bestsellers list. Now the author team has updated and expanded that resource into the just-released Doing Good Science in Middle School, Expanded 2nd Edition: A Practical STEM Guide. This new book offers chapters to help teachers assimilate STEM principles, understand and apply the NGSS and A Framework for K–12 Science Education, and integrate the Common Core literacy and writing standards into science instruction. At the heart of the book are 10 teacher-friendly, ready-to-use STEM activities that connect with NGSS and follow the BSCS 5E model. Lessons highlight key topics in the middle-level curriculum, such as energy transfer (“Keeping Your Cool”), engineering and structural design (“Bridge Buster”), and ecosystems and biological diversity (“Saving the World, One Ecosystem at a Time”).

Interactions are our focus this month—in ecosystems and classrooms, among science teachers teaching a variety of disciplines, and using the latest technology. This month’s K-College journals from the National Science Teachers Association have a wealth of articles on how to make the most of the great ideas and possibilities that bubble up via smart collaboration.

In an NSTA discussion forum, a question was raised about studying ecosystems and food chains at the elementary level. I pointed the readers to articles in this month’s edition of Science & Children, which has a variety of classroom resources and background information for teachers.
Many science lessons for young students focus on warm, fuzzy animals. Our World Without Decomposers: How Scary!* describes a series of class activities in which students examine and learn about “bugs, slugs, bacteria, and fungi.” (My middle schoolers would love this, too!) Descriptions of creating a classroom decomposing tank, exploring decomposers a local park, and reflecting on the role these organisms play in an ecosystem are the highlights of this article. [SciLinks: Decomposer, Characteristics of Fungi, Bacteria, Composting, How Does Nature Recycle Materials]
Videos, readings, and classroom activities are good, but nothing beats real outdoor experiences. Ecosystems, Up Close and Personal (The Early Years)* shows how just about any schoolyard can be an ecosystem. When students plant seeds in a school garden or even in a pot, they can begin to understand the relationship between a living thing and the abiotic factors in an ecosystem. A lesson is provided. [SciLinks: How do ecosystems change naturally?, Plant Growth]
Regardless of whether you call them pillbugs or roly-polies, The Amazing Ecology of Terrestrial Isopods* show how these arthropods can be the basis for an engaging study of interactions between organisms and their environment. The authors include a fact sheet on these critters and a description of an outdoor activity in which students observed the organisms and the characteristics of their environment. The students then created an indoor habitat (directions provided) in which they could investigate the behaviors of these low-maintenance classroom animals in more detail. [SciLinks: Arthropods]
Do your students understand that a food chain is more than a diagram of who eats what? If Energy is Neither Created Nor Destroyed, What Happens to It? (Science 101) discusses the energy transfer in an ecosystem. [SciLinks: Food Chains, Food Webs]
Not all evidence and data are numeric. With the prevalence of digital cameras and cell phone cameras, students have an evidence-collecting tool at their fingertips. Exploring Nature Through a New Lens* has suggestions for a student study of the schoolyard habitat. And if you’re thinking about turning part of the school campus into an outdoor learning center, you’ll want to read Ensuring a Safer Outdoor Experience (Safety First)*.[SciLinks: Habitats]
The authors of How Healthy Is Our Pond?* provided students with a real-life scenario for studying the characteristics of a local pond. Students observed the physical and biological surroundings and performed water quality tests for temperature, pH, nitrates, dissolved oxygen, and clarity. The authors describe these tests in detail and include photographs and samples of student data. [SciLinks: Water Quality]
Growing Gardens, Growing Minds* shows how K-4 students went beyond growing seeds in paper cups to designing a community garden at their school. They also learned about nutrition and how plants are part of a healthy diet. The article includes photographs and a grade-by-grade description of class activities related to the project. Seeding Science in Elementary Schools (Methods and Strategies) describes a school-university partnership to establish classroom gardens. [SciLinks: Plants as Food, Plants with Seeds, Seed Germination]
“Adaptation” is a word that can have several meanings, from its everyday one to a more scientific one. Habitat Change: Formative Assessment of a Cautionary Word (Formative Assessment Probes) includes a probe to study students’ perceptions of the process. [SciLinks: Adaptations of Plants, Adaptations of Animals]
Is This Alive? (Science Shorts)* is a question that intrigues students. How do we know? The 5E lesson here focuses on kindergarten students’ explorations of living things and some of their misconceptions. [SciLinks: Living Things]
Let’s Talk Trash (Teaching Through Trade Books)* suggests two trade books on the topic and includes two lessons that help students look at their own choices and how these choices can affect their communities. The 5E lesson Garbage Gurus (K-2) guides students through an analysis of “trash” to determine what might be recyclable. For students in grades 3-5, the 5E lesson Where Does Our Trash Go? examines the trash stream in their community. [SciLinks: Recycling K-4, Recycling 5-8]

Since it is now March and in my area we just had our 10^th snow day, I am dreaming of planting seeds rather than actually planting them. What should the children plant in the raised bed school garden, a tiny sliver of ground that could not be incorporated into the play area because there is a telephone pole in the way? The children offer very general ideas: “flowers,” “carrots,” and “peas” (from the older children who remember them from last spring). These are great ideas and we can do them all—first peas, and later carrots and flowers, all in small amounts. There are wonderful children’s fiction and non-fiction books and songs about gardening with children. Post your favorites in the comments below.
Like many schools, we don’t have a windowsill with full sun where we can grow healthy seedlings inside. We do sprout seeds in plastic bags, clear containers and on sponges, to see the delicate roots and sprouts grow. But growing a plant to maturity must wait until we can plant in the ground, currently under a blanket of snow.

I’m also interested in having plants that will attract butterflies because they are so pretty and the children are attracted by their colors and motion. Children do like to find ants, roly-polies, slugs and earthworm, and spot bees, too. These observations add up over time to a beginning understanding of the ecosystem, and how the small animals fit into it. The ants are often found in groups, worms are always found in or on the ground, the roly-polies and slugs are most abundant in damp places, and the bees are focused on flowers. This concept, of each animal meeting its needs within an ecosystem, is more apparent in butterflies because their needs change with change in life stage after they come from the egg as larva, change to pupa, and then to adult.

In the March 2014 Early Years column in Science and Children, I wrote about observing the growth of a fennel plant (Foeniculum vulgare) and the animals that use it, over time. In the school yard, we have a fennel plant whose leaves are food for the larvae (caterpillars) of Black Swallowtail butterflies. The adult butterfly does drink nectar from the flowers but seems to prefer the nectar of annual flowering plants. By planting another favorite Black Swallowtail larval food, parsley, nearby, we can almost guarantee that we will be able to find these caterpillars. These caterpillars are safe to touch—gently, for the caterpillar’s sake. Research the species of butterflies that live in your area to learn which are safe for children to touch and which have stinging hairs. Some species should not be disturbed because they are an endangered species. The common and not-endangered butterfly species in your region may not be the same species as the ones I have my children observe as the spring season progresses.
Resources that might be of use include online catalogues maintained by volunteers, online and in print information sheets from government agricultural services, and identification books such as the Peterson First Guide to Caterpillars of North America by Amy Wright. I like this book because it describes 120 common species and shows the caterpillars, their adult forms and many of their host plants.
Did you know that digital versions of NSTA journals are available for members to read on your computer as well as your Kindle Fire, Android tablet/phone, or iPad/iPhone?
 

As Director of Distance Learning for University of Minnesota’s Bell Museum of Natural history, each year Chris Tower created and provided professional development for more than 300 teachers throughout Minnesota and Wisconsin via two distance–learning, cross-curricular science programs: the JASON Project and BellLive.

In his current position, he has established a service-learning water quality study for fourth grade; designed and collaborated with students, teachers, parents, the administration, the city, and businesses to create a rain garden and a community produce garden; presented garden programs to other districts’ teachers, parents, and community members; worked on district-level science review teams and wrote science curriculum for upper-elementary levels; and wrote STEM curriculum for Minnesota’s Department of Education. A school technology leader, he produces a live school wide newscast with students.

“His creativity and willingness to experiment and explore new opportunities energizes our community,” says his principal. His district’s elementary curriculum coordinator describes him as “a real champion of both science and service learning” who “enhances the traditional science curriculum by making meaningful connections for students, while asking them for ways to give back to the community.”

Tower’s winning lesson, The Community Garden Environment Lesson Plan, is aimed at 4th and 5th grade students. The interdisciplinary lesson includes connections to science, literacy, and math, and includes essential elements of Service-Learning. This lesson addresses the Minnesota Science Standards related to environments, living systems, and inquiry.
