Toxic and Harmful Algal Blooms
These activities, in conjunction with Bigelow Laboratory's “Toxic and Harmful Algal Bloom" web site, will help your students gain a better understanding of toxic and harmful algal blooms. Each module below consists of background content material and related standards-based activities. Each module is independent of the others; however, some background knowledge is required to complete the lessons.
NCBI More Information: Similarity
This page summarizes the basic concept and vocabulary of sequence similarity searching. It is included for those new to the field who may not appreciate the importance of this technique in biology, who lack the vocabulary to understand the BLAST guide and tutorial or who require a basic rather than a sophisticated understanding of the methods involved. Sections include introduction, premise, terms, general approach, the BLAST algorithm, quantification, gaps, significance, and databases. Users ca
Using a Colorimetric Test to Measure pH
This laboratory exercise, appropriate for grades 5-12, engages students to use a Colorimetric test to measure pH and gain an understanding of pH and its importance to life in an aquatic ecosystem. In addition to the lab lesson plan, the site includes New Jersey Science Standards, objectives, background, vocabulary, extension ideas, and references.
Two paths to knowledge
For students who always finish their class work early or want more information than you have time to give, try curriculum compacting.
Alternative discussion formats: museum exhibit design
Designing museum exhibits encourages students to think creatively and to use a wide range of thinking skills.
When teachers don't understand
Teaching should be informed not only by the content of the discipline but also by the lives of the students.
Tools of the trade for information seekers
A guide to understanding and using search engines, directories, and the invisible web.
Observing other teachers
Learning from other teachers is an important means of professional development. Here are some suggestions for observing successful teachers in your school, in other schools, and on the web.
Setting the tone
Building a student-centered classroom culture starts on the first day of the school year.
How mentors can serve as role models, helpers, and colleagues.
America on the Move
This activity guide accompanies the exhibition America on the Move. It delivers a variety of historical primary-source materials from the exhibition directly to your classroom. Through these documents and activities, students can build a deeper understanding of how transportation shaped American commerce, communities, landscapes, and population migrations.
Decoding the Past: The Work of Archaeologists
This site introduces students to archeology -- the study of material remains to learn about past human experiences. This lesson (Grades 3-8) discusses various challenges of an archaeologist: locating a site that will yield clues about the people who once lived there, conducting excavations, and more. Students identify artifacts from a contemporary setting, describe the function of each artifact, identify methods for dating soil layers, and interpret soil profiles.
Under the Spell of ... Spiders!
Spiders are endlessly fascinating and a great school subject because they offer plenty of teachable topics that span the curriculum. We've tried to provide some of those topics here in these lessons, as for all their amazing physical features and unusual habits, spiders, with just a few notable exceptions, pose little threat to humans and are creatures deserving of understanding and respect. It's our hope that, as you work through the activities, your students will gain a new appreciation for sp
Streams in the City
These exercises are designed to guide a student to an understanding of how rainfall and storm events result in runoff over the surface of the earth. Runoff is influenced by the nature of the surface of the earth. Streamflow is particularly influenced by urbanization-the paving over of permeable surfaces with impermeable ones. In light of this, students are encouraged to think about design elements that incorporate more permeable surfaces into their own environments, including their school parkin
In this set of exercises, students will study rivers and waterways around them by using the Internet, maps, and their knowledge of local landscapes. The students will use an EPA Web site to investigate what is upstream and downstream of them. They will also look at graphs of flow in familiar river locations on a live U.S. Geological Survey Web site. Using small rocks and a washbasin, students will build a model that leads to extending their understanding of streams in different geographic locati
Aquifer on the Go
This demonstration should follow a class discussion on potential sources of pollution to drinking water supplies. To illustrate how water is stored in an aquifer, how ground water can become contaminated, and how this contamination ends up in a drinking water well. Ultimately, students should get a clear understanding of how careless use and disposal of harmful contaminants above the ground can potentially end up in the drinking water below the ground. This particular experiment can be done by e
TÜ Loodusteadusliku hariduse lektoraadi vastavatel kursustel (Loodusteaduste visualiseerimine) osalenud õpetajate koostatud interaktiivsed mudelid bioloogiliste protsesside tundmaõppimiseks. Kuigi mudeleid ei saa lugeda lõplikult viimistletuks, on nad õppeprotsessi visualiseerimiseks asjakohased: kasvõi ideede saamiseks. Kasutajal on soovitav fail enne oma arvutisse salvestada ning vajadusel täiendada.
Doctors in a Divided Society: The Profession and Education of Medical Practitioners in South Africa
Many of the goals of South Africa's new democracy depend on the production of professionals who have not only the knowledge and skills to make our country globally competitive but also a commitment to working and living here. Despite numerous reforms, the South African health system, ten years into democracy, remains divided with first world private care that ranks with middle income countries internationally at the one end and at the other extreme in the rural public sector in particular condit
Clinical Skills Examination Procedures: Afrikaans & Xhosa
Shown here are a single set of techniques which are both simple to employ and reliable for four examinations. General Examination: preparing the patient for examination; describing the patient's appearance; examination for features of specific illnesses; taking the pulse; assessing warmth, perfusion, hydration and temperature; inspecting the hands, eyes, mouth and pharynx; looking for lymphadenopathy; and inspecting the legs. Abdominal Examination: preparing the patient for the examination; look
An Introduction to Information Systems
This resource provides a useful backdrop on political communication, journalism and national development issues as priority areas for collaborative action in Africa and the Middle East. This course provides a business perspective of information systems and stresses how information systems can be used to improve their planning and operation. The nature and value of information, as well as the impact of Internet technology on organisations and society are also considered.
