Thorne, Sarah – Science Teacher, 2017
The lichen is an ideal subject for student study because it is omnipresent in school yards, easily collected and observed year-round, a pioneer of evolution on land, and a bioindicator of air pollution. After doing fieldwork on this unusual composite organism as an apprentice with a team of lichenologists, Sarah Thorne developed Learning Lichens.…

Oldershaw, Cally; Hilton, Barbara; Rocca, Alis – Primary Science, 2010
The late Tom Chester, in his role as the British Lichen Society churchyard coordinator, did a great deal to encourage the use of the churchyard as an educational tool. In his honour, the Society has created an award as part of its "Lichen Project". When the Society approached the Association for Science Education (ASE) for help in…

Samsudin, Mohd Wahid; Daik, Rusli; Abas, Azlan; Meerah, T. Subahan Mohd; Halim, Lilia – International Education Studies, 2013
In this study, the learning of science outside the classroom is believe to be an added value to science learning as well as it offers students to interact with the environment. This study presents data obtained from two days' workshop on Lichen as Biological Indicator for Air Quality. The aim of the workshop is for the students to gain an…

Young, Simon – School Science Review, 2013
The prevalence of nine indicator lichens found on trees in Northern Europe and Western Russia was used for monitoring air quality. The 4200 mile route of the survey went through eight countries. Surveys were carried out in cities, towns, countryside and forests, and along motorways. The author has conducted tree lichen surveys with pupils from…

Smith, Gregory L.; Baker, Thomas R. – Science Scope, 2003
Lichens, small and unobtrusive organisms, are seldom noticed as they cling to rocks, trees, and soil in fragile veils or crusts of splendid color and ornate textures. Their beauty is captivating and fascinating, and their purpose and origins are thought-provoking. Lichens make particularly good "bioindicators". They are bioindicators of sulfur…

Raham, R. Gary – American Biology Teacher, 1978
For teachers in search of an easily obtainable, readily dissectable, and unique living specimen to arouse the interest of their students and illustrate important biological principles, lichens are the perfect selection. Background information and experiments on lichen anatomy, physiology, and chemistry are given. An appendix gives culture media.…

Ashbrook, Peggy – Science and Children, 2016
For young children, a found acorn, stone, or lichen-covered branch can be a touchstone of an experience in nature. Children, however, should also be taught to "leave no trace." As the National Park Service advocates, visitors to natural areas should "Preserve the sense of discovery for others by leaving all natural and cultural…

McBride, Brooke B.; Brewer, Carol A. – Science and Children, 2010
Flower petals, acorn hats, exoskeletons of beetles, and lichens are just a few of the objects students may find in a surprising array of vivid colors. These tiny examples from nature's palette can be discovered in a school yard, a park, or even along the edges of a paved sidewalk...it simply takes careful observation! This article describes a…

Rudolph, Emanuel D. – BioScience, 1988
This article reviews the treatment of lichens in 93 different introductory North American botany textbooks. Topics considered are questions of relationship, independent survival, reproduction, definition, and scientific name. The author reports that treatment is uneven and often includes incomplete or erroneous information which may persist…

Shofner, Marcia; Vodopich, Darrell – American Biology Teacher, 1993
Describes an interesting field experiment examining the distribution and diversity of a single community using lichens and the animals living in them. Combining field experience and laboratory work reveals not only the biology of some unusual organisms, but also community ecology and diversity. (PR)
