Join Simon, Anita, Emily and the rest of Ms. Patel's class as they gain an understanding of how the Earth works as a system while preparing their end of the school year play.
Look inside a resistor to see how it works. Increase the battery voltage to make more electrons flow though the resistor. Increase the resistance to block the flow of electrons. Watch the current and resistor temperature change.
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.
اتبع سيمون، أنيتا ودينيس عند انضمامهم لهانا، وهوعالم محلي، في تحقيق اكتشافات جديدة في خور الصفصاف.
Play with a bar magnet and coils to learn about Faraday's law. Move a bar magnet near one or two coils to make a light bulb glow. View the magnetic field lines. A meter shows the direction and magnitude of the current. View the magnetic field lines or use a meter to show the direction and magnitude of the current. You can also play with electromagnets, generators and transformers!
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.
Pump gas molecules to a box and see what happens as you change the volume, add or remove heat, change gravity, and more. Measure the temperature and pressure, and discover how the properties of the gas vary in relation to each other.
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.
Build your own system of heavenly bodies and watch the gravitational ballet. With this orbit simulator, you can set initial positions, velocities, and masses of 2, 3, or 4 bodies, and then see them orbit each other.
