Part of kinetics is understanding reaction mechanisms. The teacher in this video introduces mechanims first by discussing the important terms: complex reaction, intermediate, catalyst, and the rate determining step (06:06).
Energy diagrams are an important concept to master when learning about kinetics. They will show up on tests like the AP exam for sure. The teacher in this video draws some energy diagrams and talks about the changes a catalyst can cause (03:49).
My Angle on Cooling
In this activity, learners discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced. Learners perform an experiment that measures how the heat experienced by a test subject changes as the distance or the viewing angle changes. Learners distinguish which effect is more important for determining the seasons on Earth. Learners examine how NASA's MESSENGER mission to Mercury takes advantage of these passive
Experiencing Parallax With Your Thumb
In this activity, learners investigate parallax, a method used to measure distances to stars and planets in the solar system. Learners can see the parallax effect in action by holding their thumb out at arm's length and following simple instructions. This activity will help learners understand how the brain uses information to detect distances. This resource also describes three other basic methods for determining distances in space: radar, standard candles, and the Hubble Law.

Climate Change - An Overview
Climate change is defined as the long term change in weather patterns over time. The greenhouse effect is the trapping of heat in the Earth by gasses like carbon dioxide and some scientists argue that increases in atmospheric greenhouse gases will trap more heat. When more heat is trapped, there is more energy to drive weather patterns. This increased heat can also have unpredictable effects such as the melting of ice caps, shifting rainfall patterns and more powerful storms. (03:12)
"All human beings are born free and equal in dignity and rights." This is what it says in the very first Article of the Universal Declaration of Human Rights.

September Song by Maxwell Anderson (spoken version)
Who really listens to the words of popular songs? They best express our deepest emotions - so said Aldous Huxley, no less. It was written for Walter Huston's voice in 1938 and it featured in the film September Affair in 1950 - a May/September romance between characters played by Joan Fontaine and Joseph Cotten - who was in fact only 12 years older. Here's Walter Huston's version - and although he isn't a great singer, he does manage to put across the essential wistfulness lacking in all o
