Chemistry 10-18-17 Conservation of Energy

CHEMISTRY – Happy Day!! We finished the chapter! Now it’s time to go apply what you’ve learned. Have you begun to think about ways you could separate that mixture? And what about a Plan B? πŸ˜‰

So can energy be destroyed? Good job on tracing the energy transformations from one form to another. Applications, applications! Make sure you can apply what you learned today – on the test (and in life!). Did I mention that already?

Hey, have you had a chance to check out the chapter 1 study suggestion sheet? Let me know if there is anything you need help with before the test! (And you’re still learning the symbols of the elements, right?!?) πŸ™‚

Physics 10-18-17 Newton’s Law of Inertia

PHYSICS: Remind me again why didn’t that pen go flying across the room instead of dropping into the bottle? Hmmm…..

So what do you reckon is the inertia of this car? Great start today relating mass to inertia! Now go forth and apply what you know to find the mass of that spool of copper wire! Wait, did a say copper wire, I meant the mass of that unknown substance! photo by Rodolfo Mari
