Standing On the Shoulders of Giants (Time Warp Monograph Series) Vol. 1 No. 13
Big-leaf mahogany is a tree species known for its beautiful wood. Over time, humans have cut down many big-leaf mahogany trees for use in furniture and other products. Because of this regular human use, big-leaf mahogany is considered vulnerable. To ensure that big-leaf mahogany harvesting is sustainable, scientists and land managers must know the conditions in which mahogany grows.

Standards addressed in this Monograph:
-
ESS3.C-M1
Human activities have significantly altered the biosphere, sometimes damaging or destroying natural habitats and causing the extinction of other species. But changes to Earth’s environments can have different impacts (negative and positive) for different living things.
-
ESS3.C-M2
Typically as human populations and per capita consumption of natural resources increase, so do the negative impacts on Earth unless the activities and technologies involved are engineered otherwise.
-
LS1.B-M4
Genetic factors as well as local conditions affect the growth of the adult plant.
-
LS1.C-M1
Plants, algae (including phytoplankton), and many microorganisms use the energy from light to make sugars (food) from carbon dioxide from the atmosphere and water through the process of photosynthesis, which also releases oxygen. These sugars can be used immediately or stored for growth or later use.
-
LS1.C-M2
Within individual organisms, food moves through a series of chemical reactions in which it is broken down and rearranged to form new molecules, to support growth, or to release energy.
-
LS2.A-M1
Organisms, and populations of organisms, are dependent on their environmental interactions both with other living things and with nonliving factors.
-
LS2.A-M2
In any ecosystem, organisms and populations with similar requirements for food, water, oxygen, or other resources may compete with each other for limited resources, access to which consequently constrains their growth and reproduction.
-
LS2.A-M3
Growth of organisms and population increases are limited by access to resources.
-
LS2.C-M1
Ecosystems are dynamic in nature; their characteristics can vary over time. Disruptions to any physical or biological component of an ecosystem can lead to shifts in all its populations.
-
LS4.D-M1
Changes in biodiversity can influence humans’ resources, such as food, energy, and medicines, as well as ecosystem services that humans rely on—for example, water purification and recycling.
-
PS3.D-M1
The chemical reaction by which plants produce complex food molecules (sugars) requires an energy input (i.e., from sunlight) to occur. In this reaction, carbon dioxide and water combine to form carbon-based organic molecules and release oxygen.
-
Cite specific textual evidence to support analysis of science and technical texts.
-
By the end of grade 8, read and comprehend science/technical texts in the grades 6-8 text complexity band independently and proficiently.
-
Determine the central ideas or conclusions of a text; provide an accurate summary of the text distinct from prior knowledge or opinions.
-
Follow precisely a multistep procedure when carrying out experiments, taking measurements, or performing technical tasks.
-
Determine the meaning of symbols, key terms, and other domain-specific words and phrases as they are used in a specific scientific or technical context relevant to grades 6-8 texts and topics.
-
Analyze the structure an author uses to organize a text, including how the major sections contribute to the whole and to an understanding of the topic.
-
Analyze the author's purpose in providing an explanation, describing a procedure, or discussing an experiment in a text.
-
Integrate quantitative or technical information expressed in words in a text with a version of that information expressed visually (e.g., in a flowchart, diagram, model, graph, or table).
-
Distinguish among facts, reasoned judgment based on research findings, and speculation in a text.
-
Compare and contrast the information gained from experiments, simulations, video, or multimedia sources with that gained from reading a text on the same topic.

What Is a Natural Inquirer Monograph?
A Natural Inquirer monograph is a short publication that focuses on a single research study. Monographs are written for a middle school audience, but they can also be adapted for both high school students and advanced upper elementary students.
Monographs include:
- One article based on a published, peer-reviewed research paper; the article keeps the research paper format (see more below) but is written in language students can understand.
- A FACTivity, which is an activity to complete after reading the article. The FACTivity helps reinforce major science concepts from the article. These activities are designed to be easy to implement, with few material requirements and options for adapting them for your audience or available resources. Some monograph may have two FACTivities.
- A short “Welcome to the monograph” article about key background information and science concepts.
- A glossary of new terms from the article or the introductory materials.
- A list of related Natural Inquirer publications as well as outside references.
- Standards correlations, including Next Generation Science Standards, addressed in both the article and the FACTivity.
Monographs may also include additional essays (called spotlights), other activities (like crossword puzzles or vocabulary challenges), and more.
Reading Modes
Monographs are available in three different formats:
- Hard copies can be ordered from the website and shipped, all free of charge.
- PDF versions of the printed monograph can be downloaded free on the website. The PDF version directly replicates the content and layout of the printed version.
- The “Read Distraction Free” option allows the monograph article to open in its own window, without the rest of the website being visible. “Read Distraction Free” is available on the article version of the monograph, which can be opened under the “Articles” tab. This version allows readers to scroll to particular sections of the article using the sidebar menu on the left side of the screen. This version also has interactive Reflection Sections and Number Crunches. Students can enter their answers, submit them, and then receive the correct answers to double-check their work. Submitted answers are not saved on the website and will disappear once the window is closed.

Introduction
This section begins the scientific article format. Much like the published, peer-reviewed study this article is based on, the introduction provides background information for the study – what is currently known and what remains unknown. The introduction culminates in the question(s) the study hopes to answer.
The introduction is also the first section with a Reflection Section. This section includes two or three questions to help kids reflect on what they’ve just learned in the Introduction. If they are using the online distraction-free reading mode, they can answer these questions directly on the website.
Use this section to:
- Review important background information that kids need to understand the study
- Connect the study to the concepts addressed in the Thinking About Science and Thinking About the Environment sections
- Understand research questions and hypotheses, including generating their own hypotheses given what they already know
Next Generation Science Standards applications:

Methods
This section is the nuts and bolts of the study design – the who, what, when, where, why, and how of the research. Contained within the Methods section are usually maps of the study location or the set-up of study plots, as well as details about what data was collected and how.
The Methods section also ends with a Reflection Section – two or three questions to help students think through what they just read. These questions are interactive on the distraction-free reading mode.
Use this section to:
- Show students how experiments and studies are designed and carried out
- Explore sampling methods and randomization
- Introduce various data collection tools (e.g. camera traps, surveys, insect collection tools, weather stations, etc.)
- Explain bias and how studies are designed to remove bias
- Help students gain experience with map reading

Additional Resources on the Website
On the website, we pair each monograph with a variety of other resources, as well. Use the tabs on the product page to browse through the following:- Related activities, including the FACTivity for each article
- An “About” essay that gives some larger context for the research the scientists conducted or more information about the science topic from the article
- A glossary of all boldfaced terms from the article
- A “Scientists and Collaborators” page that lists the people involved in the study; click on a researcher to reach their bio page and see what other articles they might be featured in
- A “Related Content” page that lists both Natural Inquirer resources about similar topics and also outside reference materials
Article Selection and Review
Natural Inquirer partners with the USDA Forest Service, so we source research studies by Forest Service scientists that have been peer-reviewed and published in reputable journals. Some of our articles have also been created in collaboration with scientists from other Federal agencies, such as U.S. Geological Survey and the United Nations Food and Agriculture Organization, universities, and other non-profits.
All monograph articles are reviewed by scientists who conducted the original research study to verify scientific accuracy. Monographs are also reviewed by student editorial review boards of middle or high school students before publication. Additionally, all monographs are reviewed by the Forest Service and the U.S. Department of Agriculture before publication.
Every monograph article includes a citation of its source study. Many educators pair the original research paper with our article to help more advanced students learn how to read formal research papers. The monograph article then serves as adapted primary literature, bridging the two articles.Lessons
