Ferns attached to a forest rock
Ferns have small, branched leaves, not to reduce gas exchange and water loss, but to increase the surface area for spore producing structures. This demonstrates that plants develop certain characteristics for very different reasons.

Rocket Car on an Inclined Plane Model
The EJS Rocket Car on an Inclined Plane model displays a car on an inclined plane. When the car reaches the bottom of the incline, it can be set to bounce (elastic collision) with the stop attached to the bottom of the incline. The car consists of the car body, two rotating front wheels, and two rotating rear wheels. The incline angle (in radians) can be changed via a textbox and the rocket’s thrust can be changed via a slider. In addition the car can be dragged to its initial position. A
Introduction to Philosophy II
This course is designed as a "topics-based" introduction to philosophy. What this means is that instead of working through the history of philosophy focusing on great historical figures and their views on different topics, we will focus on great philosophical topics and look at what historical and contemporary writers have said about them. Topics to be addressed will include the existence of God, the relation between the mind and the body, human freedom, and the foundations of morality.
The Language of Algebra
This site provides a brief review of many aspects of algebraic language and use, from symbol sets and fractions to exponents and factoring. Intended as a reference for students already familiar with algebra, it is the first section of the online text Introductory Statistics: Concepts, Models, and Applications. This resource is part of the Teaching Quantitative Skills in the Geosciences collection. http://serc.carleton.edu/quantskills/

Die Behörden erließen vorübergehend eine Tsunami-Warnung. Nach jüngsten Angaben kamen mindestens vier Menschen ums Leben, 140 wurden verletzt. T
Tommaso Treu and Mike Shara Discuss Super Massive Black Holes
Mike Shara, curator in the Department of Astrophysics at the American Museum of Natural History, sat down with Tommaso Treu, physics professor at the University of California, Santa Barbara, to discuss the importance of understanding super massive black holes and dark matter at the 217th American Astronomical Society meeting in Seattle, Washington. Treu also explained how he came to work in this specialized field.

Small Regulatory RNAs May Sharpen Spatial Expression Patterns
The precise establishment of gene expression patterns is a crucial step in development. Formation of a sharp boundary between high and low spatial expression domains requires a genetic mechanism that exhibits sensitivity, yet is robust to fluctuations, a demand that may not be easily achieved by morphogens alone. Recently, it has been demonstrated that small RNAs (and, in particular, microRNAs) play many roles in embryonic development. Whereas some RNAs are essential for embryogenesis, others ar
Solving Energy Problems
The culminating energy project is introduced and the technical problem solving process is applied to get the students started on the project. By the end of the class, the students should have a good perspective on what they have already learned and what they still need to learn to complete the project.

Earth Geography
This 1:31 long video explains how the land masses of the earth were put together before. the big fusion continent is called pangea. since there are tectonic plates that are constantly moving, pangea split apart over time. the tectonic plates are also responsible for landforms and earthquakes. The video moves rapidly so the teacher may wish to stop it to show the movements more clearly.
Science in Focus: Force and Motion: Workshop 8. Bend and Stretch
We all expect a spring to stretch or compress when a force is applied, but forces can even deform solid objects like the floor or the top of a table. In this workshop, students in a high school classroom explore ideas about tension and normal force. By applying a force to a spring and measuring the distance the spring is stretched, the students calculate the force constant or stretchiness of the spring. Lecture demonstrations using student volunteers help to illustrate that even rigid objects be
