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.
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.
What good is Beowulf?
High school students can follow the English language's evolution in Beowulf and The Canterbury Tales, and they can focus on words and their meaning as they compare translations.
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.
More search tools you haven't tried
KartOO and Profusion offer new alternatives for finding, organizing, and displaying the websites you're looking for.
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.
Spiders and monarchs and bees, oh my!
Exploring the world of insects and spiders can replace children's fear with fascination.
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.
Finding Common Ground
Finding common ground helps students make informed decisions to conserve temperate forests in the United States and central China, habitat of the endangered giant panda. Through classroom activities, on-line simulations, and field investigations students learn about the important role temperate forests play in local and global ecosystems. Action steps culminate in a Class Conservation Action Plan. In the course of this curriculum students locate the biome in which they live, explore a local habi
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
