Hon Chemistry 4-24-17 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 9-29-16 Angular Projectile Motion

    PHYSICS – So we are finally putting it all together – angular projectile motion! Here’s the lesson – some homework discussion and then angular projectile motion.

    The number one thing to remember – Never use the resultant velocity to do more than find the vertical and horizontal components! And vertical is vertical, horizontal is horizontal and don’t ever mix the two!

    Chemistry 9-5-14 Homework Update & thLAB: Density of Oil

    CHEMISTRY: I’m so excited about the work you’ve done over the last couple of days – applying what you’ve learned in class!!

    Homework for the weekend is to complete the thLAB: Density of Oil AND study SI memorization for any potential upcoming surprise quizzes. (Hint, hint!!)

    Are you clear on the thLAB: Density of Oil and what it’s all about? Here’s some discussion of the Density of Oil thLab that you might find helpful! Have a great weekend!!

    Physics 3-26-14 Waves

    PHYSICS: Hey guys! Here’s the lecture on the properties of waves. Problems are pretty simple for you, I think. Do you remember the main formula from chemistry? Speed = wavelength x frequency (c = λf).

    Easy peasy – and don’t forget the applications!

    ACT Science Reasoning Hints, 5-18-12, Day 2 ….. the rest, for now

    Are you ready to start making your own luck? Good luck as you begin practicing for the ACT this summer. Here’s the second part of the hints for taking the ACT that we did on Thursday. Practice, practice, practice!!!

    And if you are interested in a summer ACT Science Reasoning prep session, check out the form below.

    Physics – Congratulations to the Rube Goldberg Competition Winners!!

    PHYSICS: Well, I’ll make it pretty later, but for now I thought you’d want to know:

    The winners of the 2012 Rube Goldberg Competition are…………………… the sound group: Corey, Zach, and Matt. Congratulations, guys!!

    And what you really wanted to know – so far, the following students are exempt from the 2nd semester physics exam: Corey, Zach, Matt, Jakin, and Sebastian. Wow! Five! I think that’s a record. Good job, guys!

    Chemistry 5-1-12 Single Replacement, Double Replacement & Combustion Rxns

    CHEMISTRY: Wow! We did a lot today in just a very short amount of time! Here’s the lecture on the review and new notes on single replacement (with a little intro to the activity series), double replacement, and combustion reactions. Now that you’ve got everything on paper, let’s play with them tomorrow. First, the quiz. Then you’ve got to remind me to show you this really cool demo on combustion rxns. I call it “flaming bubbles”! And don’t forgot – we’ll start with the quiz! Good luck studying, I’ll be praying for you!!

    Hon Chemistry 3-27-12 Synthesis & Decomposition Reactions

    HON CHEMISTRY: Wow! So that’s where the pretty light comes from! Great job on synthesis and decomposition reactions. We’ll finish decomposition tomorrow. Now go forth and practice what you learned! (The balancing equations part, not the playing with magnesium part!) 🙂

    Chemistry 3-27-12 Multiple Covalent Bonds

    CHEMISTRY: Great job with double and triple bonds today! Here’s the lecture from Tuesday. Be careful about getting too happy with double bonding – count electrons and don’t forget CONS. And what else? Oh yes, PRACTICE, PRACTICE, PRACTICE! We’ll put one more twist on Lewis structures tomorrow.
