It took a life-threatening condition to jolt chemistry teacher Ramsey Musallam out of ten years of "pseudo-teaching" to understand the true role of the educator: to cultivate curiosity. In a fun and personal talk, Musallam gives 3 rules to spark imagination and learning, and get students excited about how the world works.

The answer is satellites, stars, planets, asteroids and maybe even aliens.
This classroom activity will show students that there is a lot we don't know about science, for example life throughout the universe. It will hopefully encourage students to question what we know and don't know, and exploration and study of the unknown.

جسم الانسان عبارة عن مجموعة من الاعضاء التى تعمل مجتمعة لتكون الجسم البشرى ولتعطيه الطاقة لاكن جسم الانسان يستطيع ان يعيش حتى بعد استئصال بعض تلك الاعضاء سواء استئصال جزئى او كلى وإن كانت بعض الاعضاء الاخرى لا يمكنه العيش دونها

There’s something special about our busy, blue marble of a planet. These talks explore why we should make strides to preserve our shared, galactic home.
These videos review the practice problems at the end of each chapter in the ACS Organic Chemistry Final Exam Study Guide. (I may have an older version.) These videos are intended to provide testing strategies that can be used for this exam as well as to help with the GRE, MCAT, PCAT, DAT, etc. since the exams use similar style questions for the organic chemistry sections

“It is crucial to remember that kids are not little adults. therefore juvenile diabetes is different from adult-onset diabetes in many aspects such as pathophysiology, developmental considerations, and response to therapy. Clinicians should be aware of a child's current and evolving developmental stages and must adapt care plans, particularly during the adolescent years.
This is, therefore, the first updated ADA pediatric T1D position statement since 2005.
As the carbon dioxide concentration of our atmosphere increases and our climate warms, the hay fever season seems to be getting longer and more severe. In this case study, students assume the a role of a public relations specialist contracted to communicate the link between climate change and pollen allergies. The activity focuses on the importance of scientific skills to careers outside science, and is most suitable for a lower-level introductory biology, human health, or environmental science course.

A video from the Extreme Ice Survey in which Dr. Tad Pfeffer and photographer Jim Balog discuss the dynamics of the Columbia glacier's retreat in recent years through this time-lapse movie. Key point: glacier size is being reduced not just by glacial melting but due to a shift in glacial dynamics brought on by climate change.

At this point in the unit, students have learned about Pascal's law, Archimedes' principle, Bernoulli's principle, and why above-ground storage tanks are of major concern in the Houston Ship Channel and other coastal areas. In this culminating activity, student groups act as engineering design teams to derive equations to determine the stability of specific above-ground storage tank scenarios with given tank specifications and liquid contents. With their floatation analyses completed and the stability determined, students analyze the tank stability in specific storm conditions. Then, teams are challenged to come up with improved storage tank designs to make them less vulnerable to uplift, displacement and buckling in storm conditions. Teams present their analyses and design ideas in short class presentations.

In this activity, students are split into groups to examine a specific band of the electromagnetic spectrum and the absorption spectra of seven atmospheric gases in that wavelength range. Using a jigsaw approach, the students regroup to have an expert on each band to examine the full spectrum, identify and rank greenhouse gases, and estimate Earth's temperature from satellite data.
