Around the World in 1896
This is a lesson in which students take a trip around the world in 1896 using an online collection of 900 images. The collection includes photos of railroads, elephants, camels, horses, sleds and sleighs, sedan chairs, rickshaws, and other types of transportation, as well as city views, street and harbor scenes, landscapes, and people in North Africa, Asia, Australia, and Oceania.
An introduction to teacher research
Every day, teachers develop lesson plans, evaluate student work, and share outcomes with students, parents, and administrators. Teacher research is simply a more intentional and systematic version of what good teachers already do.
Blogging: an introduction
Weblogs, or "blogs" for short, have many uses in education, as tools for publication, research, administration, and more.
Not your mother's math teacher
North Carolina's 2001-2002 Teacher of the Year, Carmen Wilson, talks about real-world math and teachers' roles as professionals.
Oral history and student learning
Oral history enriches historical knowledge; enhances research, writing, thinking, and interpersonal skills; gives students a connection to the community; and helps all students feel included.
Greeting your Limited English Proficient (LEP) students in their own language
Even a simple "Hello" or "How are you today?" can help to integrate a student into a new environment. This article offers strategies and tools for teachers wishing to learn a few words of a new language.
The 2004 presidential election in historical context
Historian William E. Leuchtenburg talks about past presidential elections and how the 2004 election fits or defies precedents.
Mali Empire and Djenne Figures
Archeology offers the most tangible evidence of earlier civilizations. Although archeology has already provided invaluable information pertaining to the life styles and skills of the peoples from this region of West Africa, the archaeological record is still incomplete. The figurative sculptures featured in this resource furnish one part of the historical puzzle of this region. These handsome terracotta sculptures are from the Inland Niger Delta region near Djenne (pronounced JEH-nay; also spell
Kõrv loodusesse - loodushelid ja helid looduses
Loodushelid ja helid looduses. Veebilehed info ja illustratsioonidega vastavatest liikidest, võimalik kuulata helindeid. Kõrv loodusesse kasutab kahte erinevat kokkusurutud helifaili formaati: mp3 ja real audio. Üldjuhul võimaldab mp3-formaat paremat kvaliteeti, kuid faili maht on suur. Real audio on väiksema failimahuga, kuid sellega kaasneb kehvem kvaliteet. Aeglase ühenduse korral on seetõttu otstarbekam valida real audio helindid. Kiirema ühenduse korral tasub kuulata parema kvalitee
Starting with psychology
The most ‘important and greatest puzzle’ we face as humans is ourselves (Boring, 1950, p. 56). Humans are a puzzle – one that is complex, subtle and multi-layered, and it gets even more complicated as we evolve over time and change in different contexts. When answering the question ‘What makes us who we are?’, psychologists put forward a range of explanations about why people feel, think and behave the way they do. Just when psychologists seem to understand one bit of ‘who we are’

We all know that the heart is very important but what exactly does the heart do? Why is the blood so important? What functions do the lungs perform? In this unit, we will try to provide at least a basic understanding so we can answer these questions and begin to understand why knowing about the heart is important for all sports people. Before that we will take a look at the human body.
Biotic Indices of Stream Macroinvertebrates for Fun and (Educational) Profit
Water quality monitoring activities can support student inquiry into ecological concepts and pollution issues, as well as offer insight into integrating field and lab work. This exercise provides students with practice in identification (to order or family level) of stream macroinvertebrates that they've previously collected. Provided information indicates water pollution tolerance of the various taxa. Students use the data to calculate several different biotic indices for the macroinvertebrates
Regulation of Blood Glucose Levels in Normal and Diabetic Rats
This exercise demonstrates the crucial role insulin plays in blood glucose homeostasis in mammals. Three pairs of fasted rats are tested in each of three different regimes; one rat of each pair is normal and the other is diabetic. The first pair is administered an oral glucose load and a placebo injection of saline. The second pair is administered an oral glucose load and an insulin injection. The third pair is administered an oral placebo of water and a placebo injection of saline. The blood gl
Moral and ethical principles in end of life care
In many areas of health care, and especially in such areas as palliative care, increasing attention has been paid in recent years to patient autonomy, and the need to respect it. Autonomy has come to be seen as a very important aspect of the interaction between patients and those looking after them, and forms the basis for many ethical commitments, such as telling the truth to patients, and seeking their consent for health care interventions. In this unit we look at quite a wide range of ethical
One reason why ticks are considered to be arachnids is because they do not have antennae like insects do. Ticks suck blood from animals and are sometimes difficult to remove from the host's skin.
