Dr. Thomas Chasteen's site offers links to multimedia files related to chemiluminescence, gel electrophoresis, how a grating works, gas chromatography and mass spectrometry, titrations, atomic emission detector, and much more. The site is a good collection of helpful visual learning tools that chemi
Combination locks : I forgot the combination! How many combinations will I have to try?
This activity asks the student to find the number of possible combinations for a lock showing the numbers 0 to 39. It is part of the Figure This! collection of 80 online mathematical challenges emphasizing real world uses of mathematics. The solution to the combination question applies the technique of using a smaller number of possible arrangements to study a problem. Students learn to use a tree diagram to model possible outcomes and explore the mathematical meaning of the term combination. Th
This document examine wind power as an energy resource. The reading will define wind and discuss topics such as (1) The history of wind machines, (2) Today's windmills, and (3) Types of wind machines. This resource is structured as an informational handout to supplement your energy activities or to generate discussion questions. Copyright 2005 International Technology Education Association
Biomass : energy from wood, garbage, and agricultural waste
This resource explores the non-renewable resource of Biomass. As a organic material, biomass stores sunlight in the form of chemical energy. Biomass fuels include wood, wood waste, straw, manure, sugar cane, and many other byproducts from a variety of agricultural processes. Other focal topics will include types of biomass and the carbon cycle. Copyright 2005 International Technology Education Association
Cancer Biology 3 - Prof. Yi Li (Part 1)
The third cancer lecture for the Computer-Aided Discovery Methods course taught at Baylor College of Medicine. This lecture covers cancer stem cells, differentiation, metastasis, and cancer types by organ of origin.
Create a Coral Reef
In this hands-on OLogy activity, kids learn about coral reefs by building a diorama that has models of different types of coral and other sea creatures. The activity opens with Amy O'Donnell, an educator at the AMNH, introducing kids to coral polyps and reefs. The illustrated, step-by-step directions show kids how to construct a diorama that contains models of a brain coral, a sea fan, a sponge, and sea anemones. It also includes Cool Coral Facts, a look at museum dioramas, and tips for "Taking
This PowerPoint presentation is part of the Whitman College petrology course. The presentation covers the origin of basaltic magmas. Two types of basalt in ocean basins are compared (tholeiitic and alkaline). Composition of mantle-derived magmas and sources of mantle material are listed. Discussion of how the mantle melts, touching on the contribution of volatiles, pressure and composition, is included. The slide show includes figures comparing enriched vs. depleted mantle. This resource is part
Igneous Rocks of the Ocean Basins
These lecture notes introduce magmatism and petrology as they relate to the oceanic lithosphere. The notes cover ophiolite sequences and types of volcanic settings found in ocean basins. A section about basalt includes discussion of location, composition and origin of mid-ocean ridge basalts. Ocean island basalts are further discussed with regards to occurrence, composition and origin. These notes include graphs, maps and phase diagrams. This resource is part of the Teaching Petrology collection
Geochemistry of Igneous Rocks
This website contains an abundance of data on the geochemistry of igneous rocks. The site provides very brief descriptions of many types of terrestrial and lunar igneous rocks, their regional distribution and classification, and examples of their geochemical trends and fingerprints. Graphs that plot the geochemical composition of both terrestrial and extraterrestrial igneous rocks are also featured. This site could be useful for upper level geology students doing independent research, as well as
This site, which accompanies an introductory structural geology class at the University of Leeds, UK, contains information on faults. Topics include normal faults, thrust faults, strike-slip faults, faults and stress, and soft-linked fault systems. The site features explanations of the three basic types of faults with informative diagrams and a photo gallery.
This NASA site explains the three major types of atmospheric aerosols - volcanic emissions, desert dust, and anthropogenic aerosols - and how they affect global climate. The site discusses the generation and atmospheric distribution of these aerosols, as well as the chemical and physical processes by which they create global cooling.
This 11-slide PowerPoint presentation presents a short succession of schematic diagrams illustrating the structural evolution of anorthosites. The slides discuss the relative abundance of rare earth elements, describe six types of anorthosite occurrence, and contain pictures showing anorthositic texture. This resource is part of the Teaching Petrology collection. http://serc.carleton.edu/NAGTWorkshops/petrology03/index.html
A Classification of Metamorphic Rocks
This 24-slide PowerPoint presentation describes the classification of metamorphic rocks using texture and composition. Foliation, lineation, cleavage, schistosity, gneissose structure, hornfels, and granofels are discussed. Specific metamorphic rock types and modifying terms (porphyroblastic, spotted, augen, para-, ortho-) are defined and photographs of some are provided. This resource is part of the Teaching Petrology collection. http://serc.carleton.edu/NAGTWorkshops/petrology03/index.html
Environmental Catalyst Module
In the Environmental Catalysis Module, a joint project with the Institute for Environmental Catalysis at Northwestern University, students learn what a catalyst is and become aware of the use of catalysis to promote environmental protection. Besides introducing the concept of catalysis, the module also focuses other issues such as catalytic selectivity, specificity, poisoning, condition optimization, and waste minimization. The first activity of the module introduces the concept of catalysis in
Language arts: elementary grammar
This module contains three different kinds of exercise which test elementary level grammar skills in English. The exercises concentrate on identifying parts of speech, different types of sentences and sentence completion.
Japanese: Kanji - Lesson 1
The purpose of this tutor is to assist people who are studying the meaning and writing of the kanji (Japanese characters) following James W. Heisig's method called 'Remembering the Kanji'. 15 Kanji characters are taught, beginning with the numbers 1 to 10. The module makes use of a kanji-matching game as well as multiple-choice and text entry question types. Hints and timers are sometimes used.
Elementary Mathematics: Times Tables I
Learn and practice times tables. This is the first of two modules and practices the 2, 3, 4, 5 and 10 times tables. It includes multiplication testing, corresponding division exercises and missing-operand exercises as part of a range of different task types designed to develop an all-round understanding of the times tables.
British History from the Romans to the Normans
A learning module about early British history, orientated towards primary school. The module is intended for use in conjunction with a suitable children's book on the subject. When using this module, it is recommended to make books available to the child for reference while working with the module. It may be helpful to work with your child and help them find the answers in the book(s) at first. The module includes questions from the departure of the Romans and the first arrival of the Angles and
Refine your English vocabulary, starting with easy words for children, and ending with the most complex of lexical rarities. About 500 words are contained in the module's internal database, which is used to generate unlimited combinations of randomised tasks. Question types include many games, such as hangman, anagrams and memory. More conventional tasks such as pair matching and multiple choice are also included. The vocabulary is divided into different levels, beginning with easier levels suit
