This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Baseball pitchers aren’t born knowing how to throw a ball – it takes years of training and practice to hone this ability. Although prior studies have examined how throwing mechanics differ between youth and adult pitchers, no reports have followed the same group of individuals year after year to watch their skills develop. Now, a US-based research team has sequentially tracked young pitchers to identify the biomechanical changes that occur as a pitcher sharpens their skills. The researchers recruited kids from youth baseball leagues who were in their first season playing as pitcher. Each participant was asked to throw 10 full-effort fastballs from the pitching mound to home plate. Before throwing, the pitcher was outfitted with 23 retroreflective markers. The three-dimensional motions of these markers were tracked through 12 synchronized high-speed cameras..."

Most students point to Walter White as a chemistry anti-hero—using crystalized fulminated mercury, disguised as crystal meth, as a grenade to blow up a drug lord that wronged him. Explosions are engaging, exciting parts of chemistry, yet dangerous to society when unplanned, such as unexpected water heater explosions. This unit will look at the components that make reactions spontaneous and explosive, including energy, enthalpy, entropy, and how they apply to physical and chemical changes. Focus will be on quantifying reactions and phase changes and working on the match concepts connected to kinetics and thermodynamics. To keep students engaged with the complex mathematical components, students will be using each lesson as a way to research and explore exciting explosions, such as that in Breaking Bad, and water heater explosions, building a model of their understanding. After finalizing their model of explosions, students will then apply their model to a community issue, such as air-bag safety. Students will design a safe and effective airbag that incorporates multiple concepts from the unit, and includes quantifications to ensure their safety.

Students learn how common pop culture references (Harry Potter books) can relate to chemistry. While making and demonstrating their own low-intensity sparklers (muggle-versions of magic wands), students learn and come to appreciate the chemistry involved (reaction rates, Gibb's free energy, process chemistry and metallurgy). The fun part is that all wands are personalized and depend on how well students conduct the lab. Students end the activity with a class duel a face-off between wands of two different chemical compositions. This lab serves as a fun, engaging review for stoichiometry, thermodynamics, redox and kinetics, as well as advanced placement course review.
