Volcanoes provide clues about what is going on inside Earth. Animations illustrate volcanic processes and how plate boundaries are related to volcanism. The program also surveys the various types of eruptions, craters, cones and vents, lava domes, magma, and volcanic rock. The 1980 eruption of Mount St. Helens serves as one example.
Intrusive Igneous Rocks
Most magma does not extrude onto Earth’s surface but cools slowly deep inside Earth. This magma seeps into crevices in existing rock to form intrusive igneous rocks. Experts provide a graphic illustration of this process and explain the types and textures of rocks such as granite, obsidian, and quartz. Once again, plate tectonics is shown to be involved in the process.
Anyone undertaking a building project must understand mass wasting — the downslope movement of earth under the influence of gravity. Various factors in mass wasting, including the rock’s effective strength and pore spaces, are discussed, as are different types of mass wasting such as creep, slump, and landslides. Images of an actual landslide illustrate the phenomeno
The weight of a mountain creates enough pressure to recrystallize rock, thus creating metamorphic rocks. This program outlines the recrystallization process and the types of rock it can create — from claystone and slate to schist and garnet-bearing gneiss. The relationship of metamorphic rock to plate tectonics is also covered.
Running Water I: Rivers, Erosion and Deposition
Rivers are the most common land feature on Earth and play a vital role in the sculpting of land. This program shows landscapes formed by rivers, the various types of rivers, the basic parts of a river, and how characteristics of rivers — their slope, channel, and discharge — erode and build the surrounding terrain. Aspects of flooding are also discussed.
Evolution and the Tree of Life What makes a snake a snake, and a lizard a lizard? What distinguishes one type of lizard from another? And how did so many types of reptiles come to be? Session 6 focuses on questions like these as we continue our study of the fundamentals of evolution. Building upon key ideas introduced

Connecting With the Arts: What is Arts Integration?
This program presents three instructional models for integrating the arts: independent instruction, team-teaching, and collaborations with community resources. Participants will also explore informal, complementary, and interdependent curricular connections, and see examples of what these different types of arts-integrated instruction look like in the classroom.
How to Keep Score in Tennis
How to Keep Score in Tennis. Part of the series: How to Play Tennis. Scoring in tennis is kept by no-ad scoring and regular scoring. Both types of scoring are based on a four point system. Keep score in a tennis match with tips from a certified tennis pro in this free video on tennis.
This is an excellent slideshow (with voice narration) that explores the art of storytelling. The narrator highlights three different types of fiction templates.
Flute Vibrato with Jennifer Grim
There are 2 types of vibrato-one that comes from your throat and one that comes from your diaphragm. This video shows you how to produce both types. (1:40)
Choosing Supplies for Homeschooling
This video shows how to pick out simple homeschooling supplies for each student, which can be used for a variety of subjects. A homeschool explains how to choosing supplies for homeschooling depends on the child's areas of interest, but basic supplies include writing utensils, different types of paper, textbooks and other crafts.
Liverworts, Mosses, and Ferns
This video gives a quick overview of some different types of spore-bearing plants. Dr. Matt von Konrat explains the reproduction of liverworts, mosses, and ferns to a high school group of students. Audio is poor but information is good. Run time 07:50
Plant Reproduction: The Pine Tree
Pine trees actually produce two types of pinecones. This video addresses both the male cone and the female cone as well as their parts. Using computer generated pictures, the narrator explains the reproductive process for a pine tree. The narrator also addresses the special adaptations of the pine needle. Run time 02:41.
Data Quality: Missing Data
This module describes how missing data can be managed while maintaining data quality. It explains how to plan for missing data; defines different types of "missingness;" outlines the benefits of documenting missing data and illustrates how to document missing data; and describes procedures to minimize missing data. Upon completion of this module, students will be able to explain why data managers should strive to minimize missing data and develop a plan to record or code why data are missing.

Jon Lewis discusses his new book on The Godfather.
13 - Banking: Successes and Failures
Banks, which were first created in primitive form by goldsmiths hundreds of years ago, have evolved into central economic institutions that manage the allocation of resources, channel information about productive activities, and offer the public convenient investment vehicles. Although there are several types of banking institutions, including credit unions and Saving and Loan Associations, commercial banks are the largest and most important in the banking system. Banks are designed to address t
Virtual laboratories in Molecular and Cell Biology - Intracellular signalling
A virtual laboratory which allows users to analyse intracellular signalling pathways. The programme allows the student to stimulate cells for different periods of time and analyse phosphorylation/activation of kinases in the signalling pathways, using SDS-PAGE and immunoblotting. Use of different cell types (dominant-negative mutants) and pull-down assays allows them to derive the hierarchy in the signalling pathways. The programme first introduces the theory behind the techniques. It then takes
Use networked services effectively to provide access to information
By developing their awareness of, and effectively using a range of, networked services practitioners enhance their responses to client requests for information. It contains activities and resources to facilitate self-paced learning. Topics include: types of databases, responding to client requests for help, the internet, bibliographic databases, kinetica, new developments and putting it all together.
Tool for Stereographic Projection
This tools allows you to draw stereographic projections for different crystal types using different poles for the projection axis. It also allows you to draw circles of a specified angle around either individual poles or all poles with a spacing larger than a selected value.
Introduction to Freshwater Invertebrate & Plant Sampling
Short video providing a summary of why freshwater invertebrates and plant abundances are studied and the broad types of methods used. Aimed at students without previous field experience and linked to other more detailed methods videos up loaded to Jorum Open, which can be found using keywords Freshwater Ecology or Ecology Field Techniques.
