Hello! Welcome to my Science Screencasts! I am attempting to incorporate some blended learning as an instructional strategy and flip my classroom whereby students watch some video presentations at home and then perform tasks and assignments based upon them in class.I'm still new to the process so I expect them to get better over time.
Use the sidebar on the left or up top to navigate more quickly to the topic you want. I will separate them by course once I produce enough of them. For now they will be listed alphabetically and for your viewing pleasure, me getting smashed on a bed of nails....
Introduction to Units | powerpoint | assignment |
This first video introduces units, defines them, explains their importance, goes over some famous unit conversion errors and mentions the danger associated with not using units.
Manipulating Units and Conversion Factors | powerpoint | assignment |
This second video goes through the rules for manipulating uits, and then explains what conversion factors are.
How to Convert Units using the Factor-Label method | powerpoint | assignment |
This third video goes straight into conversion problems.
Advanced Conversions | powerpoint | assignment |
This fourth video goes through several more advanced multi-step and multi-part conversion problems. For example, converting miles per hour into feet per second is explained step by step.
Ionic, Covalent, Metallic and Intermolecular Bonds
Intro to Bonding: Ionic Bonds | powerpoint | assignment |
This first video briefly introduces Chemical bonding and then goes over ionic bonds, what they are, and how they form in detail. The formation of ions and common ionic charge are aslo covered.
Disassociation | powerpoint | assignment
THis video goes over disassociation in CHemistry, talks about water's polarity and how it seperates ionic compounds back into the cations and anions that joined together. A visual example of salt being placed in water is shown.
Periodic Trends | powerpoint | assignment
This video builds on the foundation set by Coulomb's law, nuclear charge and electron shielding. Trends in ionization energy, atomic size, electronegativity and chemical reactivity are discussed.
Density of an Object cut in half? | powerpoint | assignment |
What happens to the density of an object when it is cut in half?
Two Advanced Density Problems | powerpoint | assignment |
Mr. Sapone's highly loved solid sphere density problem where you are given only the mass and circumference of a sphere and have to calculate its density. After that we caclulate the mass of air in a room in kilograms and convert it into pounds.
Stopping Distance| powerpoint | assignment |
A brief look at the physics behind stopping a car and the dangers of not paying attention. Reaction time, breaking distance and dimensional analysis are covered.
