Reinforcing quantitative skills with applied research on tombstone-weathering rates.
This Journal of Geoscience Education article describes a tombstone weathering exercise that reinforces quantitative skills with applied research. The article describes an exercise designed and carried out by students in a surficial processes course. Students measured the rates of tombstone weathering, compiled and analyzed data. The complexity of the data involved in this exercise helps students demonstrate for themselves that mathematical analysis can give meaning to data.
European Starlings and Woodpeckers
In this Starting Point investigative case, students will explore niche competition and population ecology by developing plans for species density studies. They will also develop a plan to re-establish a species (the woodpecker) in an area where there are almost none left. Users can access information regarding learning goals, context for use, teaching notes and tips, teaching materials, assessment hints, references and topics covered.
This page is a portal to an in-depth exploration of integrating student peer review into introductory-level geoscience classes. It includes an introduction to the concept of peer review, reasons and methods for its use, examples of electronic peer review in a geoscience context, and extensive references. This page is part of the larger Starting Point collection.
Call to Halt the Nuclear Arms Race
Dr. Randall Forsberg is executive director of the Institute for Defense and Disarmament Studies, a think tank she founded in 1980 with the aim of reducing the risk of war and minimizing the burden of U.S. military spending. In this video segment, she describes the reach of grassroots activism at the height of 1982's national Nuclear Weapons Freeze Campaign, which called for a bilateral, verifiable halt to new production of nuclear weapons. In the interview she conducted for War and Peace in the
Is there water on Mars?
Is there liquid water on Mars? By experimenting with water as it changes state and investigating some effects of air pressure, students not only learn core ideas in physical science but can deduce the water situation on Mars by applying those concepts.
Investigating the Climate System: Weather
This activity helps students learn how to find, interpret, and describe weather data. Students learn also about drought, flooding, wind and dust storms, hurricanes, and lightning, as well as the Tropical Rainfall Measuring Mission (TRMM) satellite -- the information it provides and why that information is important.
Ask an Astronomer for Kids
This site provides answers and photos for 200 common questions about astronomy and objects in space. Topics include planets, stars, the solar system, comets, asteroids, galaxies, and the night sky.
Students will observe the behavior of termites and draw conclusions about their behavior.
Carex communis habit
Carex communis habit. For context, see: Carex communis species page and Carex Interactive Identification Key.
Longshore Drift and Depositional Landforms
This site provides animations and images showing a variety of depositional landforms resulting from longshore drift. Animations demonstrate both naturally occurring landforms and what happens when humans interrupt sediment transport processes through river and coastal engineering projects. The site also features a collection of coastal photographs. These resources can be integrated into lectures, labs or other activities.
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.
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.
Gümnasist biotehnoloogia pealispinnal
Artiklis käsitletakse geenitehnoloogiaga seonduvat gümnaasiumi õppekavast põhjalikumalt, ent õpilastele lisamaterjaliks sobivalt. Selgitatakse geenidega manipuleerimise meetodeid, DNA sekveneerimist, DNA-testi molekulaarbioloogilisi aluseid, DNA paljundamist (PCR).
Roberge 6.302 Lecture 12
Description not set
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.
