Invasive Species – Spanish
In this edition of Natural Inquirer, you will learn about several different invasive species. Invasive species are plants, animals, or organisms that are not native to the ecosystem they are in, and are likely to cause harm to the environment, the economy, or human health. You will learn about how these invasive species spread and the studies that scientists conduct to better understand and stop the spread of invasive species. After this Natural Inquirer edition, you will be able to help spread the word about what invasive species are and how to control them!

Standards addressed in this Journal:
-
ESS2.C-M1
Water continually cycles among land, ocean, and atmosphere via transpiration, evaporation, condensation and crystallization, and precipitation, as well as downhill flows on land.
-
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.
-
ETS1.A-M1
The more precisely a design task’s criteria and constraints can be defined, the more likely it is that the designed solution will be successful. Specification of constraints includes consideration of scientific principles and other relevant knowledge that is likely to limit possible solutions.
-
ETS1.B-M1
A solution needs to be tested, and then modified on the basis of the test results, in order to improve it.
-
ETS1.B-M2
There are systematic processes for evaluating solutions with respect to how well they meet criteria and constraints of a problem.
-
ETS1.B-M3
Sometimes parts of different solutions can be combined to create a solution that is better than any of its predecessors.
-
ETS1.B-M4
Models of all kinds are important for testing solutions.
-
ETS1.C-M2
The iterative process of testing the most promising solutions and modifying what is proposed on the basis of the test results leads to greater refinement and ultimately to an optimal solution.
-
LS1.A-M3
In multicellular organisms, the body is a system of multiple interacting subsystems. These subsystems are groups of cells that work together to form tissues and organs that are specialized for particular body functions.
-
LS1.B-M2
Animals engage in characteristic behaviors that increase the odds of reproduction.
-
LS1.B-M3
Plants reproduce in a variety of ways, sometimes depending on animal behavior and specialized features for reproduction.
-
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.D-M1
Each sense receptor responds to different inputs (electromagnetic, mechanical, chemical), transmitting them as signals that travel along nerve cells to the brain. The signals are then processed in the brain, resulting in immediate behaviors or memories.
-
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.A-M4
Similarly, predatory interactions may reduce the number of organisms or eliminate whole populations of organisms. Mutually beneficial interactions, in contrast, may become so interdependent that each organism requires the other for survival. Although the species involved in these competitive, predatory, and mutually beneficial interactions vary across ecosystems, the patterns of interactions of organisms with their environments, both living and nonliving, are shared.
-
LS2.B-M1
Food webs are models that demonstrate how matter and energy are transferred between producers, consumers, and decomposers as the three groups interact within an ecosystem. Transfers of matter into and out of the physical environment occur at every level. Decomposers recycle nutrients from dead plant or animal matter back to the soil in terrestrial environments or to the water in aquatic environments. The atoms that make up the organisms in an ecosystem are cycled repeatedly between the living and nonliving parts of the ecosystem.
-
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.
-
LS2.C-M2
Biodiversity describes the variety of species found in Earth’s terrestrial and oceanic ecosystems. The completeness or integrity of an ecosystem’s biodiversity is often used as a measure of its health.
-
LS4.A-M2
Anatomical similarities and differences between various organisms living today and between them and organisms in the fossil record enable the reconstruction of evolutionary history and the inference of lines of evolutionary descent.
-
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.

What Is a Natural Inquirer Journal?
A Natural Inquirer journal is a collection of 4-8 articles on a related science topic. Journals are written for a middle school audience, but they can also be adapted for both high school students and advanced upper elementary students. Some journals are particularly suited to high school students; you can find our grade level recommendations in the tags on the product page or by filtering journals by grade level.
Journals include:
- Four to eight articles based on published, peer-reviewed research papers; the articles keep the research paper format (see more below) but are written in language students can understand.
- A FACTivity for each article, 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 articles in a journal may have two FACTivities.
- A short “Welcome to the journal” article about key background information and science concepts that unify the articles included in the journal
- A glossary of new terms for each article and the introductory materials.
- A list of related Natural Inquirer publications for each article as well as outside references.
- Standards correlations, including Next Generation Science Standards, addressed in the articles and the FACTivities.
Journals may also include additional essays (called spotlights), other activities (like crossword puzzles or vocabulary challenges), and more.
Reading Modes
Journals 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 journal can be downloaded free on the website. The PDF version directly replicates the content and layout of the printed version. You can also download individual articles as pdfs.
- The “Read Distraction Free” option allows the individual articles to open in their own window, without the rest of the website being visible. These articles can be found 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.

Additional Resources on the Website
On the website, we pair each journal 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 journal
- A glossary of all boldfaced terms from the journal
- A “Scientists and Collaborators” page that lists the people involved in the studies in the journal; 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 journal articles are reviewed by scientists who conducted the original research study to verify scientific accuracy. Journals are also reviewed by student editorial review boards of middle or high school students before publication. Additionally, all journals are reviewed by the Forest Service and the U.S. Department of Agriculture before publication.
Every journal 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 journal article then serves as adapted primary literature, bridging the two articles.Lessons
