Hale, in collaboration with the Strategic Literacy Initiative at WestEd. (*see appendix A for
complete details)
Literacy Plan Outline
1st Quarter:
Metacognitive Logs – a yearlong literacy routine.
Science in the News – a yearlong literacy routine.
2nd Quarter:
Read a nonfiction science book, then write a children’s science book.
3rd Quarter:
Read a biography of a scientist, then write and present a historical vignette based on
that historical figure.
4th Quarter:
Read a work of fiction – science related, then participate in a journaling and “book club”
sharing activity.

Curriculum – 7th and 8th Grade Science
Appendix A – “Literacy in Science: A Natural Fit”
Reading is an essential part of science literacy, but what, when, and how can we incorporate
reading in the science classroom? Like many of my colleagues, I avoided relying on the textbook
by engaging students in lectures, hands-on activities, demonstrations, and videos.
Unfortunately, as each year passed, my students read less while I worked harder.
I wanted students to become the scientifically literate citizens envisioned in the National
Science Education Standards: students who read science, enjoy reading science, and even
experience the passion I feel for the natural world. However, with 65% of incoming freshmen at
my school reading below the sixth-grade level, it was clear that our science curriculum,
especially the textbook, did not include motivating or accessible reading for most students. To
bring reading back into our science classrooms, my colleague, Ann Akey, and I designed four
quarterly reading projects with yearlong literacy routines that we use successfully with our
ninth-grade students, including English language learners.
An inquiry approach to literacy and science
We created these projects as part of a three-year professional inquiry into literacy in science
with our colleagues at the Strategic Literacy Initiative at WestEd. The two yearlong literacy
routines we developed are based on Reading Apprenticeship, an instructional framework
offered by the Strategic Literacy Initiative (Schoenbach et al. Promoting student literacy
through inquiry A Natural Fit in LITERACY Janet Creech and Gina Hale February 2006 1999) to
support middle and high school student literacy in content areas. Reading Apprenticeship
encourages reading in classrooms as an active problem-solving process. Students and teachers
engage in a shared inquiry into literacy by taking mental risks as they read together and discuss
their reading processes, confusions, and methods of resolution. Creating a classroom climate
Page | 53
Curriculum – 7th and 8th Grade Science
that supports inquiry is essential to both science and literacy learning. This connection to
inquiry made the Reading Apprenticeship approach a natural fit in our science classrooms
(Schoenbach et al. 2003).
Yearlong metacognitive conversation
To begin our classroom inquiries into science literacy, we talk about our thinking processes
every day as we delve into lab procedures, graphs, data tables, and all the different “texts” of
science. I model talking aloud about my own thinking processes and encourage students to
“think aloud” about how they make sense of what they are doing. Through this metacognitive
conversation, students learn that text includes labs, data, and their own work, and that reading
is an active problem-solving process.
As this way of working becomes comfortable and routine, I teach students to record their
thinking by writing down their confusions, questions, connections, clarifications, and
summaries in “Metacognitive Reading Logs.”[Editor’s note: The tools and projects described in
this article, including Metacognitive Logs, were created by the author and can be downloaded
from the Reading Apprenticeship website at http://wested.org/stratlit.]
As a yearlong literacy routine, these logs take on different forms depending on their purpose.
Some are as simple as a vertical line drawn down the center of a piece of binder paper with an
“I read” heading on the left and an “I thought” heading on the right. At other times logs may
contain a series of sentence stems to choose among and complete such as “I was confused by”
or “This reminded me of.”
Often students are asked to write questions, short summaries, or personal connections to what
they are reading. Some logs have a printed format, some are kept in spiral notebooks, and
others are simply written on the edges of the reading handout itself. This routine metacognitive
writing and conversation supports students throughout the year as they encounter more
difficult texts and complex reading tasks. Once we establish this foundation, we are ready to
expand our reading experiences.
Four non-textbook reading projects
We begin our reading projects in the first quarter with “Science in the News” (SIN), which we
also continue throughout the year—along with the Metacognitive Logs—as a yearlong literacy
routine. In the second quarter we introduce a nonfiction reading project and accompanying
children’s science book writing project. In the third quarter students read a biography of a
scientist and present Interactive Historical Vignettes (Roack and Wandersee 1993). In the fourth
quarter, students read fiction books and participate in book clubs (Steineke 2002). Although we
Page | 54
Curriculum – 7th and 8th Grade Science
sequenced these projects to take advantage of students’ growing skills, motivation, and
stamina, any of these projects can be used independently of the others (Figure 1).
Science in the News
To help students read, evaluate, and discuss scientific issues and findings that appear in popular
media, we developed SIN, a format to help students have an informed scientific perspective.
Figure 2 summarizes the student objectives of SIN.
We assigned the first SIN as homework, providing a structured report format and instructions
to find a science article in a newspaper or magazine (Figure 3). We thought our highly
structured report format would help students read deeply. Looking at student work samples,
however, we realized that even with relatively accessible text, such as the daily newspaper,
students were not able to read and respond to the science without more help. The report
format was not enough support; we had to teach our students how to read science in the news.
I started by finding an article to read and discuss in class. In small groups, students read the
article and completed a SIN reading together, discussing how they approached highlighting the
methods and results and how they constructed summaries. Teams shared their results with the
whole class while I recorded their reading strategies on an overhead. Later we read anonymous
student work samples, evaluating them using our new understandings of how to read SIN.
Our efforts paid off. With practice, students are able to do the SIN reading activities
independently. Teams discuss the science in the reading, instead of how to read the science.
Working together, students become expert readers of science in the news. More importantly,
we are learning that science literacy is not a fixed object; people are not good readers or
nonreaders, but evolving readers. Figure 4 (p. 26) shows the grading rubric for this project.

In the fall our classes make a trek to the school library’s nonfiction science section. We give
students a chart that describes where science topics can be found and let students look for a
book that interests them. Once they find one, we negotiate. Because our goals for this project
are to build fluency, stamina, and motivation as well as general science knowledge, our focus is
helping students find books that genuinely interest them and that are not too difficult. As a
result, I start to see science-based library books appearing at Sustained Silent Reading—20
minutes of reading a day, a school wide policy—instead of magazines and newspapers.

Monthly Science in the News objectives.
◆Highlight the research methods or procedures.
◆Highlight in a different color the results or conclusions.
◆Use highlighting to summarize procedures and results.
◆Report the name and expertise of a researcher or scientist involved.
◆Draw a picture or diagram of an important aspect of the research.
◆Compose a brief summary of the big idea.
◆Ask a question of the researchers or the author.
During the next four to five weeks students complete most of their reading outside of class with
the support of teacher-generated Metacognitive Logs designed specifically for nonfiction text. I
collect and check these logs weekly to give students written encouragement on their progress.

Curriculum – 7th and 8th Grade Science
When they finish reading, students demonstrate their understanding of the topic by writing and
illustrating a children’s science book on the same subject.
Tapping into students’ interests produces some amazing results and encourages student
engagement. One English language learner filled her book with photos and descriptions of her
own beloved parrots. Another student, who produced little other work during the year, wrote a
book about lizards, which he proudly shared. Many students chose their children’s book
projects (from their science class!) to include in their schoolwide assessment portfolios as
evidence for meeting reading and writing expectations.
Read a scientist’s biography and present an interactive historical vignette
Empowering students with personal knowledge about real scientists and the work they do is
our primary goal for the biography project. For instance, during a class discussion of the
Tacoma Narrows Bridge failure, a student who had just finished Joseph Strauss’ biography for
his reading project eagerly explained that Strauss, who designed the Golden Gate Bridge,
planned for the bridge to flex up and down several feet to prevent a failure like the Tacoma
Narrows disaster.
When we initially introduced the biography project, we reencountered a familiar problem. We
lacked motivating and accessible text to read. Our library had a scant collection of dusty,
unused volumes of “classics.” Over the next three years, we added biographies of women
scientists, such as A Feeling for the Organism:

The Life and Work of Barbara McClintock (Keller 1983); scientists of color, such as Charles Drew:
Life-Saving Scientist (Shapiro 1997); contemporary researchers, such as The Beak of the Finch
(Weiner 1994) about the work of Peter and Rosemary Grant; and the accessible biography
series Great Minds of Science and Scientists Who Changed the World. For a full list of the books
we have added, visit http://wested.org/stratlit and click on “Resources,” then “Resources for
Teachers,” and finally “Extensive Reading in Science.”
Once we had enough texts involving scientist biographies that students could and would read
independently, students could do most of the reading outside of class. We developed new
Metacognitive Log prompts to help students make connections to the influence of culture and
society on scientific thought. Once students finish their reading, they write 250-word vignettes
about a major event in the scientist’s life. They dress like their scientists, bring props
representing the scientists’ work, and read their vignettes in small groups. The “scientists” ask
their peers in these small groups to discuss opinions about their work and discoveries.

Question is related to article and thoughtful.by using a checklist to assure that all required
aspects of the scientist’s life are covered. Students are asked to use this checklist to prompt the
speaker if omissions occur, thus creating a collaborative approach to discovering the scientist’s
achievements with the reporting student serving as resident expert.
This is my favorite literacy activity of the year. I give extra credit if students make and wear a
life-size mask of the scientist’s face for their presentation. Later, I hang the masks around the
room to create a gallery of scientific greats “participating” in class for the remainder of the
school year. Allowing students to assume identities of scientists is a powerful tool to help them
connect to the process of scientific discovery and the impact of political and religious beliefs on

science class? When considering what students should read, we uncovered a closely guarded
secret: Science people love to read good fiction about science. When reading fiction, we engage
with the ideas of science in imaginative and enjoyable ways that we might not when reading for
information. [Editor’s note: For more on science fiction in science class, see “Science Fiction and
Scientific Literacy,” p. 38, in this issue of The Science Teacher.] We wanted students to have
access to this experience while providing opportunities for them to evaluate and discuss the
scientific ideas they encountered. Our critical reading and discussion goals make the book clubs
our most demanding project, which is why we save it for last.
Book clubs are discussion groups of four to five students who have chosen to read the same
book. To facilitate book choice, I bring copies of the books to class for students to look through
and talk about. They rank first, second, and third choices on an individual, reading-level
appropriate list. I use their choices to arrange book club groups. The book clubs meet twice a
week during 100-minute blocks, plan their own reading schedules, and discuss their books. Each
student assembles and decorates a reading journal specifically designed for fiction narrative.
Page | 61
Curriculum – 7th and 8th Grade Science
New Metacognitive Log prompts help students make connections to situations or characters in
the novel and analyze the science presented in the story.
Students bring these journals with them to their book club and use them as the basis for group
discussions that often lead to new insights about the far-reaching impact of science in their
lives. As they contribute to scientific and literary conversations with their peers, students see
themselves as successful readers of science. (For examples of books, see Figure 5.)
Making progress
Three years into our inquiry, one thing is clear: Our students have become more capable and
more willing science readers. Although many students read well below grade level, they could
still become science readers. Similarly, while we are not reading teachers, we can teach
students to read science. Our goals in beginning this inquiry were to improve student’s
attitudes toward science reading and give students the tools to become lifelong science
readers.
We made significant progress toward establishing the kind of scientific literacy that “expands
and deepens over a lifetime, not just during the years in school” (NRC 1996, p. 22). By the end
of the school year, reading becomes an established routine in my classroom, and students’
attitudes about reading change dramatically. When I announce the first book project in the fall,
the general response is “What, we have to read the whole book?” By the time the last project
rolls around in late spring, students say, “Read another book? Okay, I can do that.” ■
