Measuring the Motion of a Coronal Mass Ejection

Extinction events have happen throughout geologic history, but only five mass extinctions occurred over the last 4.5 billion years. Scholars view fossils from a layer of sediment during an extinction event and observe patterns to draw...

This in-depth organic chemistry lab walks learners through an investigation of the effect of initiator concentration on the resulting molecular weight of polystyrene. It is important that you use this lesson with experienced chemistry...

Enhance your current chemistry curriculum with a short video that demonstrates how to calculate the molar mass of a compound. There is also instruction for conversion between moles and mass, outlined in simple steps and demonstrated in a...

Relative molecular masses sure have a lot of decimal places! Watch the video to learn how the number of particles in one mole of carbon-12 determines relative atomic and molecular masses. Viewers also learn how to calculate the atomic...

Have a blast learning how rockets defy gravity! Show your physics scholars the calculations scientists use to relate the mass of the rocket and its fuel to the force required to fight Earth's gravitational pull. No rocket? No problem!...

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.

General chemistry class members engage in a mini-unit on mole conversions. Through nine lab activites with varying degrees of difficulty, they practice measuring mass and volume, molar calculations, and stoichiometry. Terrific teacher...

New things are created all the time while others disappear, does the Law of Conservation of Mass mean your drone might be made out of dinosaurs? The 16th video in a series of 29 begins with a timeline of scientific discoveries related to...

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...

Scholars apply concepts learned in both Algebra II and Chemistry to answer the questions on the provided worksheet. The activity allows for extra practice in both classes and helps connect concepts usually taught in isolation. The...
