Creatures that "glow" in the night
This Wisconsin Center for Environmental Education activity (PDF) encourages students to practice experimental design and scientific writing through the study of bioluminescence. Students observe and experiment with bioluminescent dinoflagellates (Pyrocystis fusiformis), learning how and why they produce light. The activity includes information for teacher preparation, an introduction to bioluminescence, defined vocabulary terms, a list of necessary materials, procedure, assessment questions, and

Historian William E. Leuchtenburg talks about past presidential elections and how the 2004 election fits or defies precedents.
In pretending, we learn to navigate with ease between real and imaginary worlds while learning the differences between them. Using our imaginations encourages original thinking, flexibility, adaptability, empathy, and the ability to generate multiple solutions to a problem. Pretend play helps us learn to think visually and spatially and to both capture and express ideas.
All Creatures Microscopically Small
In this lesson, students investigate the physical and behavioral characteristics of different microbes and create research- based 'Microbe Biographies.' Students then visually compare microbe sizes and examine how the size of a microbe relates to its physical and behavioral characteristics. This lesson is part of the New York Times Learning Network, a service in which lesson plans are created to accompany newspaper articles.
Asia and Pacific Islands: Peace Corps

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
Elektroonilised töölehed II klassile integreeritud arvutitundide läbiviimiseks
Töölehed on valminud reaalsest vajadusest muuta lastele arvitunnid huvitavamaks ning efektiivsemaks teiste ainetundide suhtes. Arvutialased teadmised on integreeritud teiste õppeainetega. Töölehed on valminud praktilise töö käigus, mida 2. klassi lapsed lahendasid koolis ainetunni raames arvutiklassis ja ka väljaspool seda. Töölehed on jaotatud õppenädalate kaupa, iga nädala jaoks on koostatud kolme õppeaine töölehed. Igasse õppenädalasse kuulub matemaatika tööleht, mis on p

Calisphere Themed Collection - 1780-1880: California in Transition: Californio Society, 1830s-1880s
This is a primary source photo collection on Californios, elite families that received large land grants from Spain and Mexico, flourished during the 1830s to 1880s. The hand-drawn diseño maps underscore their vital connection to land ownership. The more formal surveyed maps that followed US acquisition of California show changing values regarding land ownership. As Californios lost land and power in the late 19th century, they tried to adapt to these changes by using social networks to maintai

These images of the California missions show the transformation of the mission structures over the past two centuries. Some show the types of people who would have lived in or visited the missions. The missions mark California’s Spanish colonial past, and remain today as sites for community gatherings and heritage.

This scientific investigation uses hatching and development in brine shrimp as the biological system in which to demonstrate the laboratory model of teaching experimental design.
Animal Defenses: Zebra
Zebras generally stay in herds together. Zebras standing together may tend to look like one very large animal to predators. Also, predatory attacks send the zebras running in every direction. The stripes could confuse the attacker as to which animal it is chasing after, leaving it without any food in the end.
