Good Housekeeping Green Seal

Green Certifications: 
Good Housekeeping Green Seal


Though I compiled this information for a study on greenwashing and laundry detergent, the information pertaining to the label and certification may extend into other types of products. When in doubt, be an informed consumer and read, read, read! I try to link and reference all of my findings. - Janna


The Good Housekeeping Green label has a spot in my Green Washing laundry study because of the seven products listed on the GH site as having this certification, Tide Coldwater liquid laundry detergent is one of them. I was a little surprised, because of the many many Tide bottles I saw during this study, none of them had this seal. I tried images online, and none of the Coldwater bottles have it. Perhaps the certification expires; perhaps the seal is not something brands put on their labeling but something that serves as an in-house warranty for subscribers of Good Housekeeping. It's hard to tell how old the list of items is, as there is no date anywhere on the page... and the list is an 7 item slideshow. The seal was introduced in 2009, The seal seems largely based on how "green" the manufacturing process or material sourcing is.

Green Seal Label

Green Certifications:
Green Seal Label

Green Seal is a third-party certification for goods and services. The company Green Seal, Inc. is a non-profit organization that started in 1989, when there were no other environmental certification programs (GreenSeal, 2011). The mark may appear on a product label, a hotel or restaurant brochure, or a custodian's uniform.

Green Seal certifies household cleaners, specialty cleaners, laundry care products, cleaning services, bath soap and shampoo, personal care and cosmetic products, printing paper, kitchen papers (coffee filters and more), compact fluorescent bulbs, paints, recycled latex paint, windows, and stains and finishes. Each has it's own set of standards.

EPA DFE and Safer Choice labels

Green Certifications:
US EPA DFE / Safer Choice


Though I compiled this information for a study on greenwashing and laundry detergent, the information pertaining to the label and certification may extend into other types of products. When in doubt, be an informed consumer and read, read, read! I try to link and reference all of my findings. - Janna

The United State's Environmental Protection Agency started the Design for the Environment (DFE) label in 1992 and became the  Safer Choice label in 2015 February. The requirements did not change with the design, and some products still carry the older label. (At the time of my study Purex Natural Elements still had the DFE label (2015 November). However, the label is now a small family of labels, denoting various uses.

Teaching Moment: Maria Sibylla Merian's 366th Birthday

Teaching Moment!




Today's Google Doodle is a very pretty figure with leaves and animals. The hovertext proclaims April 2 as "Maria Sibylla Merian's 366th Birthday".

Amsterdam 1705
Wikipedia says Maria Sibylla Merian was a naturalist and scientific illustrator who studied plants and insects and made detailed paintings about them. She was born in 1647 in Frankfurt, Holy Roman Empire (now in Germany) and received her artistic training from her stepfather Jacob Marrel, who was a still life painter.


When she was 52 she traveled to the Surinam jungle in South America to understand metamorphosis in as many species as possible. There she discovered a new species, but was known to have huge trees cut down just to collect the insects. (Not a very eco-friendly tactic, from a modern point of view).

She published her major work "Metamorphosis insectorum Surinamensium", containing her careful observations and documentation of the metamorphosis of the butterfly, and is considered the most significant contributors to the field of entomology (the study of insects).

 Though it was difficult for women to work in science during Medieval times, during the 16th and 17th centuries of the Scientific Revolution women could work in science Germany. There, the tradition of female participation in craft production enabled some women to become involved in observational science, especially astronomy. Between 1650 and 1710, women made up 14% of all German astronomers.

Still, according to Michon Scott "Metamorphosis Insectorum Surinamensium was often judged harshly during the 19th century. Merian was occasionally criticized for depicting insects on plants they didn't inhabit, but she explained that she didn't want to show the same plant again and again. One picture that drew particular scorn showed the murder of a hummingbird by a wretched tarantula. Reverend Lansdown Guilding, who, in the words of one historian, "never set foot in Surinam," called the plate "entomological caricature." What upset him, besides the bird-killing spider, was the depiction of ants building bridges with their bodies — a process that surprises no one today" (Scott 2011).

For more information check out a biography on her, like Kim Todd's Chrysalis: Maria Sibylla Merian and the Secrets of Metamorphosis. I know I will!

Psychology and Motivation

Motivation is that which propels a person to put effort into a task. Motivation can come from internal interest and desire or from external rewards or requirements. Students who have high interest and a reasonable challenge may find themselves highly motivated towards learning and have high achievement. Students with low interest or too great a challenge will not be supported sufficient internal motivation to highly achieve in the academic task. Students can be motivated externally by rewards or requirements but there is a risk that the achievement will become solely tied to the reward and interest and intrinsic (internal) motivation will be low. This sort of motivation can result in low quality work or "just enough" achievement. It is important to try to reinforce intrinsic motivation and use extrinsic (external) motivation sparingly. A student with only extrinsic motivation will not achieve highly, and if they attempt to due to requirement, may be met with anxiety or burnout. A student intrinsically motivated will be more likely to keep themselves on task and complete higher quality work because they want to put more effort into the task in order to receive enjoyment and emotional reward!

Weiner's attribution theory states that individuals are motivated to discover the attributions (perceived causes of outcomes) of their own performance and behavior (Santrock 2011). In other words, when something happens to them as a result of something they did, they ask why. If a student gets a bad grade on a test they are not content with knowing their grade, they want feedback. They want to know what they did poorly on, they want to know "what they did or did not do" to get a bad grade (hopefully in order to correct it). The student will come to a causal conclusion based on their perceptions of a situation and their combination of causal attributions. According to Weiner there are three dimensions to attributions: locus (they are the cause, or something else of the cause), stability (the extent to which the cause remains the same or changes), and controllability (the extent to which the individual can control the cause). A student with a set of causal attributions described as "internal-stable-uncontrollable" may conclude that they are simply not smart enough to take the exam properly. A student with "internal-stable-controllable" causal attributions may blame themselves for "never studying". Students with "external-stable-controllable" attributions may blame the teacher for being biased, and "external-unstable-controllable" attributions may cause the student to blame their friends for not helping them enough!

A student that thinks the reason they do poorly is because the teacher does not like them has an external locus of control. This attribution is stable: they blame something that can consistently be the cause (as opposed to an unstable cause like bad luck). They student does have control of the situation and the cause, either in their method of test preparation (or lack thereof). A teacher can attempt to change these attributions by identifying them and then working with the student to move their locus of control into their own hands. Giving a student the tools and scaffolding to succeed gives them control; whether or not they use that material comes down to motivation.

According to Maslow's Hierarchy of needs a human being's needs must be satisfied in a particular sequence. A human being must first have adequate food, sleep, and water. Without these the human does not function. Next the human being requires safety. This can come in the form of a home or shelter, or protection from physical harm within those structures. Without these the human cannot have love and belongingness, which is the next set of needs. A human being needs affection and community. Once these are achieved the human can progress to have self-esteem. From this point in the hierarchy it is easy to see how failings in any of the previous tiers preclude people from having self esteem. A hungry child cannot feel safe. An abused child cannot readily feel love. A lonely child cannot achieve positive self-esteem. Without all this a human cannot realize one's potential and reach the top tier, "self actualization".

A teacher can work to give students the motivation to self-actualize and realize their potential in the classroom via extrinsic motivation, but must first understand what kind of motivation orientation the student has. According to Developmental psychologists children can display "helpless orientation" and seem trapped by their perceived lack of ability. They may frequently say things like "I'm not very good at this" even though they may have demonstrated success in the task previously (Santrock 2011). Students may have "performance orientation" and be focused on the outcome of their actions or abilities. These students believe that success results from winning. "Mastery oriented" students may be self-motivation students that attack tasks analytically and are happily challenged by difficult tasks instead of feeling overwhelmed by them. Students may exhibit combinations of these orientations. For example, I recognize that I have both mastery and helpless orientation. I organize difficult challenges for myself, analyzing how and when I could complete them, and am excited as much by the planning process and execution as the result. However, less than significant setbacks result in my shying away. This chapter particularly struck me as it almost seems my key phrase is "I'm just not very good at this". It became a crutch when I was younger and I still work on it today. Examples of this orientation mix litter my house in minor ways, in the form of unfinished sewing projects, half filled puzzle books, abandoned roller blades, etc. I started the project, excited by something new and difficult (freehand embroidery, let's say) and when I made a mistake that would require me to undo almost an hour of stitching, I put it away and declared myself a poor embroiderer. I have not gotten completely away from the helpless orientation but I am actively working on it.

Blueprint for Reform

In reading the “Blueprint for Reform – Reauthorization of the Elementary and Secondary Education Act” by the United States Department of Education and forwarded by President Barack Obama, I am struck by the President's comment “[other] countries are being smarter about how to educate their students”. Based on this, and my interest in teaching science, I chose to dissect the section “A Complete Education”. The section addresses strengthening instruction in literacy and in science, technology, engineering, and mathematics, while reforming standards. It addresses support for teachers in implementing and dealing with “more rigorous standards”. It particularly focuses on “high-need” schools and the awarding of state funded, competitive, “Focus Grants” to the ones who have adopted common, state-developed, college- and career-ready standards, or use technology to address student learning challenges in literacy. The reform mentions plans to expand access to college coursework and other accelerated learning opportunities, and improving access to a well-rounded education in general. In the Science, Technology, Engineering, and Mathematics section the reform states:

States will award competitive subgrants to high-need districts to support comprehensive STEM instruction in the grades and schools with the greatest local need. Programs must provide effective professional development for teachers and school leaders; high-quality state- or locally-determined curricula, instructional materials, and assessments; and interventions that ensure that all students are served appropriately. Subgrantees may use program funds to integrate evidence-based, effective mathematics or science programs into the teaching of other core academic subjects and for technology-based strategies to improve STEM education.

The reform goes on as such, mentioning higher standards and teacher support, answering all the hows with “throw money at the one's most in need”. What about the ones not “most in need”? The President said that the renovation of the plan would “renovate a flawed law” but “raise the expectations for our students [and] for our schools”. In this document I simply could not see how this motivating talk of higher standards and smarter graduates through higher standards and grants could be implemented in my own neighborhood school without qualifying for the self-identified rigorous grants for those only in the highest need. So I asked the Internet.

The Department of Education's website contains a more thorough explanation of the plan for the Complete Education. Chillingly, it first informs me that “From among U.S. postsecondary institutions, 16 percent of undergraduate degrees are awarded in STEM-related fields. By comparison, ... South Korea awards 41 percent (Phillips, 2007)”. In fact, most of the section is statistical data of the failing of teachers and students, with occasional sprinkles of victories like “The proportion of students achieving at the Basic level or above on the NAEP mathematics exam is increasing”. Then, an obvious and yet profound statement is made: “Teacher content knowledge in mathematics and science is important … Content experience varies among high school science faculty, who may not have a degree in the subject they are assigned to teach”.

This very important statement is addressed in the Supporting Science, Technology, Engineering, and Mathematics Education document. It claims the reforms plan to ensure that more prospective teachers, including STEM teachers, have access to high-quality preparation programs by doubling the funding for these programs. According to STEMfinity and the Department of Education's website this funding largely comes in the form of grant programs like “Investing in Innovation Fund” and competitive programs like “Race to the Top”. The document also asks states to hold teacher
preparation programs accountable for preparing teacher graduates. Quality teachers who are successful in their preparation can be recognized and rewarded with advancement opportunities (the document does not specify what kind, perhaps the proposed “Science, Technology, Engineering and Math (STEM) Master Teacher Corps”) and additional compensation.

The reform appears to address the inability of current United States graduates to compete in the global job market in the STEM fields, and it's solution is to “raise standards” either metaphorically or through “improved assessment” and offer grants for the most needy schools who are willing to align their standards to the Federal standards and show they are making headway. Since I have never won the lottery I will presume my school will neither be the schools who do not need such grants (who does not need more resources, after all), nor be among the “most needy” schools that will receive them. The quality of my teaching falls to me. I must accept the teacher-preparation education I can get and build on it through periodic self-assessment and continual cultivation of my skills and resources. Money would certainly afford a teacher physical resources for their students in the form of newer textbooks, overhead projectors or computer projectors, and laboratory materials. Barring governmental windfall my greatest resource will be my dedication to instilling the passion and curiousity of science in my students, and my creativity. As a future science teacher I appreciate the possibility of more resources for my neighborhood school but do not believe these standards and methods effectively address the issue for the majority of schools.

Santa's Reindeer - Alaska Department Fish & Game

*From:





Santa's Reindeer

Santa’s Magical Reindeer (R.t. saintnicolas magicalus) look very similar to common reindeer or caribou, but have many characteristics that distinguish them from the seven common subspecies: barrenground (Rangifer tarandus granti), Svalbard (R.t platyrhynchus), European (R.t. tarandus), Finnish forest reindeer (R.t. fennicus), Greenland (R.t. groenlandicus), woodland (R.t. caribou), and Peary (R.t. pearyi).

Home Range and Population: Santa’s reindeer live at the North Pole. They are cared for by Mr. and Mrs. Claus and a few specially trained elves. Even though there are only nine R.t. saintnicolas magicalus, they are not listed as a threatened or endangered species. The life expectancy of Santa’s reindeer is infinite. There have been no deaths or fatalities, though some very close calls have been reported due to slippery rooftops and heavy jet traffic around the Los Angeles airport. The nine reindeer are named: Dasher, Dancer, Prancer, Vixen, Comet, Cupid, Donner, Blitzen, and Rudolph. All are extremely agile, quick, and friendly.

General Description and Differences Between Subspecies: Among the common subspecies of reindeer, the largest bulls shed their antlers in late October and the small bulls and non-pregnant cows shed their antlers in April. It is not known when or if Santa’s reindeer shed their antlers. We do know, from a few furtive sightings, that their antlers appear to be extremely velvety and robust in late December. Santa’s reindeer also have the unique and remarkable ability to fly. The Claus’ have helped to further develop and condition this ability enabling them to fly great distances in a very short time period, provided they receive frequent carrot snacks.

Rudolph: One of Santa’s reindeer, Rudolph, was born with a genetic abnormality. His nose is bright red. As a calf, the other reindeer excluded Rudolph and often made disparaging remarks about his nose. However, this genetic abnormality became his greatest asset. One fateful, snowy and foggy Christmas Eve, Santa summoned Rudolph for his bright red beacon of a nose. Rudolph guided Santa and his sleigh through the treacherous night by the light of his nose. Had it not been for Rudolph, Santa’s sleigh would have been grounded. Christmas stockings would have remained devoid and limp, and Christmas day would have been marked with cries of sad disappointment. From that fateful eve forward, Rudolph has been revered and honored by his fellows and through stories, legends and songs.

Little more is known of Santa’s reindeer. They remain well loved and rarely seen, though several reports of harness bells and hoof sounds on rooftops are reported each Christmas Eve.
