The Lifestyle Project
This innovative project offers a way for students to learn about environmental alternatives by modifying their own lifestyles. It is a three-week exercise for students to reduce their impact on the environment by changing the way in which they live from day to day. This website contains an article about the Lifestyle Project and all the materials needed to teach the project. Materials include a baseline quiz, worksheets, energy facts and figures, and an Excel spreadsheet for students to calculat
Weather Front Animations
This site features GIF and Flash animations that illustrate wave cyclone formation and the formation and characteristics of warm, cold, stationary, and occluded fronts. The animations can be paused and rewound to stress important points. These resources are suitable for use in lectures, labs, or other teaching activities.
Resources on Alaska History and Politics
This National Park Service website offers links to a variety of articles about the history and politics of Alaska. Users can download PDF articles about World War II in Alaska, the Alaska Goldrush, and national historic places. The site also features links to educational resources such as teachers' guides to teaching about historic places and culture.
Voicing Your Views: Letter to the Editor
Students will explore the editorial section of the newspaper and understand what it is.
Women of Protest: Photographs from the Records of the National Woman's Party
This site presents 448 photos documenting the National Woman's Party's push for ratification of the 19th Amendment and passage of the Equal Rights Amendment. Taken from 1875-1922, these photos include portraits of leaders and tactics used by the organization -- picketing, pageants, parades, demonstrations, and hunger strikes.
California Gold: Northern California Folk Arts from the Thirties
This is a multi-format ethnographic field collection project, undertaken during the New Deal, that includes sound recordings, still photographs, drawings, and written documents from a variety of European ethnic and English- and Spanish-speaking communities in Northern California.
Climate reconstruction using Foraminifera in Deep Sea Sediments
This Wright Center for Science Education lesson plan (PDF) uses pasta as an analog to teach students how deep sea sediments are collected and analyzed to identify different foraminifera species in order to interpret global paleo temperature change. It includes National Science Education Standards as well as background information and images, a list of materials needed, a step-by-step photo-guided walk-through of the activity, evaluation questions, and reference list.
Winogradsky Column Unit: Chemical and Physical Change
This two-part activity leads Physical Science students, grades 8-12, to explore chemical change using Winogradsky Columns. Part 1 constructs student concepts concerning chemical and physical changes. Part 2 asks students to compare physical versus chemical changes and observe chemical changes in a Winogradsky Column, and teaches them to build their own column. It includes the following student pages: introductory lesson, Winogradsky Column lesson, challenge your thinking activity sheet, how to m
Alternative discussion formats: museum exhibit design
Designing museum exhibits encourages students to think creatively and to use a wide range of thinking skills.
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.
This exercise introduces students to analysis of evolutionary relationships both by analysis of molecular similarity and by cladistic techniques. The molecular analysis uses both paper-and-pencil and bioinformatics comparison of the amino acid sequence of the hemoglobin beta chain of eight vertebrates. The cladistic exercises introduce students to cladistic principles, and then allow students to solve hypothetical problems both with and without homoplasy. Students then test their cladistic abili
California juniper tree
The juniper tree is a gymnosperm from the phylum of conifers. The cone is the reproductive structure of conifers. The berry-like structures are actually cones where reproduction occurs.
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.
Gravitropism is the turning or growing in a different direction of a plant in response to gravity. This plant's shoots grow upward and exhibit negative gravitropism because they are growing away from gravity's pull.
Fly on a leaf
Flies are insects that eat dead plant and animal material. Their ingestion and digestion of detritus leads to respiration and excretion of important nutrients back into the soil and water.
Skunk (Mephitis mephitis)
Skunks are omnivores and eat chipmunks, mice, green plants, and insects. Owls and coyotes prefer to eat these smelly animals.
MODIS Snow Cover over Europe
The Moderate Resolution Imaging Spectroradiometer (MODIS) provides data in 36 spectral bands, some of which are used in an algorithm to map global snow cover. The animation shows the dynamic behavior of the advance and retreat of continental snow cover over Europe for the winter of 2001-02 from MODIS-derived 8-day composite snow maps with a spatial resolution of about 5 km.
