Physics 1-31-22 Circular Motion
PHYSICS: Wonderful visual today of the difference in angular speed and linear speed! Thanks for playing along!!
So is being unbalanced a bad thing? Here’s our discussion of circular motion.
Hon Chemistry 1-31-22 Percent Yield
HON CHEMISTRY: So are you a cookie dough lover? Not me – I like my cookies crispy!
Here’s the last of the applications of stoichiometry problems – percent yield. Lots easier that limiting reactants I think. You realize what we’ve done… we’ve finished the chapter!! Now let’s see if you can apply what you know – good times!
Physics 1-26-22 Stability & Torque Problems Review
PHYSICS: Ohhhhhhhhh….so that’s how they can walk across that line! Wait – why do they keep moving their bodies?? Great opportunities for discussion and application!?!
Here’s the discussion from today on how stability relates to center of mass. At the beginning, a quick look at a couple of torque problems from the homework, Torque Worksheet 2.
Hon Chemistry 1-25-22 Limiting Reactants
HON CHEMISTRY: So if you have 11 roller wheels, how many roller blade skates can you make? You know, really, limiting reactant is almost that simple. Well, the concept is anyway! You deal with limiting reactants in your life all the time. Now we’re just applying that same concept with chemical reactions! 🙂
Physics 1-25-22 Rotational Equilibrium Problems
PHYSICS: Great job with rotational equilibrium problems today! Here’s out look at putting rotational equilibrium together with translational equilibrium. The beginning of good times!
Chemistry 1-25-22 Balancing Chemical Equations Practice
CHEMISTRY: Okay, maybe balancing equations isn’t exactly like this, but…..
Great practice today! Do you feel better about balancing equations? Here’s our short review of balancing equations from today.
Hon Chemistry 1-24-22 Stoichiometry
HON CHEMISTRY: Great job with reaction stoichiometry today! Were you able to apply what you remembered about moles from earlier this year? Don’t forget the keys! Now all you need is some practice and you’ll have it down pat!!
Physics 1-24-22 Torque & A Look at Rotational Equilibrium
PHYSICS: Awesome job with asymmetrical Christmas trees and torque!! So how’s the balance in your life right now? 😉
Homework UPDATE: For Tuesday night would you like to switch the Torque 1 and 2 worksheets? Torque 1 is longer. Let’s talk about it in class tomorrow.
Chemistry 1-24-22 Describing Chemical Reactions
CHEMISTRY: So you learned last semester how to determine if a chemical reaction has taken place. How would you go about describing a chemical reaction to someone? Here’s our discussion from today on writing balanced chemical equations!
First step in writing equations? Make sure you can write chemical formulas! First step to that? Memorization!!
So tell me again – how do you know if a chemical reaction has occurred? Here’s another hint – not necessarily a good idea to try to make your own blue flame thrower! Click here to watch the Periodic Videos Blue Flame Thrower Video
