Controlling Body Mass

Teach the basics of mass spectrometry with a hands-on instructional activity. The fourth in a series of six lessons explores how mass spectrometry measures the ionic composition of an element. Learners then compare and contrast relative...

The human body is an amazing thing! Explore the body with your high school class as they investigate each system in detail. They learn components of each organ system and disease processes that can negatively affect general health and...

Facilitate learning by using small objects to teach the principles of atomic mass in your science class. Pupils determine the average mass of varying beans as they perform a series of competitive experiments. They gather data and...

Demonstrate the complex process of calculating a weighted atomic mass. Given the atomic mass of isotopes of a sample, the lesson instructor models the calculation. Multiple examples give learners the opportunity to review the process.

99 percent of the species that have ever lived on this planet are extinct. The best way to understand when another extinction could happen is to study the previous five mass extinctions. The video discusses each one, the cause, the...

Extinctions constantly occur, but what sets off a mass extinction event? Young scientists study the data from the previous five mass extinctions to better understand their causes. Then, they learn the impact each extinction had on our...

Know your number! Diabetes and heart disease both increase with higher body mass index numbers. Understanding the body mass index (BMI) helps scholars take control of their own health. They view a comparison of what various BMI...

The sun's corona, rarely seen from Earth, takes up massive amounts of space many times the size of our planet. Viewers discuss and view how scientists study the corona of the sun. They observe the impact of coronal mass ejections on...

How do you teach a student with visual impairments about the conservation of mass? You use tactile models that represent the theoretical concept. Baking soda and vinegar are used to add gas to a deflated balloon. Learners will feel the...

Have you ever been so tired you missed a major announcement? Eric Wieschaus woke to a call explaining he won the Nobel Prize, but he thought it was just a dream until Christiane Nusslein-Volhard, a co-winner, explained it to him later...
