ان موضوع هذا الفيديو الخاص بالوحدة النمطية هو كيفية تصنيف الحيوانات على أساس مدى ارتباطهم. ان الهدف التعليمي الرئيسي هو أن الطلاب سيتعلمون كيفية انتاج أشجار متطورة السلالات على أساس الخواص الفيزيائية وعلى تسلسل الحمض النووي معا. سيتعلم الطلاب أيضا لماذا تكون الموضوعية والطبيعة الكمية لتسلسل الحمض النووي هي الأفضل حين يتعلق الأمربتصنيف الحيوانات على أساس مدى ارتباطهم. تشمل معرفة المتطلبات الأساسية لهذا الدرس أن يتوفر لدى الطلاب بعض الاستيعاب لطبيعة الحمض النووي وأن يكون لديهم الإلمام بقاعدة-قواعد الاقتران ومع كتابة تسلسل الحمض النووي.

The Flaws of Averages
Conditions of Use:
Remix and Share
Rating

This learning video presents an introduction to the Flaws of Averages using three exciting examples: the ''crossing of the river'' example, the ''cookie'' example, and the ''dance class'' example. Averages are often worthwhile representations of a set of data by a single descriptive number. The objective of this module, however, is to simply point out a few pitfalls that could arise if one is not attentive to details when calculating and interpreting averages. The essential prerequisite knowledge for this video lesson is the ability to calculate an average from a set of numbers. During this video lesson, students will learn about three flaws of averages: (1) The average is not always a good description of the actual situation, (2) The function of the average is not always the same as the average of the function, and (3) The average depends on your perspective. To convey these concepts, the students are presented with the three real world examples mentioned above.

Lunar Lander
Conditions of Use:
No Strings Attached

Can you avoid the boulder field and land safely, just before your fuel runs out, as Neil Armstrong did in 1969? Our version of this classic video game accurately simulates the real motion of the lunar lander with the correct mass, thrust, fuel consumption rate, and lunar gravity. The real lunar lander is very hard to control.
