CHEMISTRY – Happy Homecoming! How’d you like playing with precipitates? Here’s the lecture on chemical and physical changes, and also on the laws of conservation of mass and energy. Good job on tracing the energy transformations from one form to another. Make sure you can apply all this on the test (and in life!). 🙂
That precipitate lab was fun!
The candle “lab” today was really fun!
Do we need to write the lab up for homework or are we doing that in class?
Garrett – You’ll do that in class tomorrow. Just read it for tonight.
I cant wait for future labs in this class!
Mrs. Skinner,
Where can I find the difference between quanitative and qualitative?, I could not find it in my notes.
I have always had trouble with deciding whether something is a chemical or physical change but the thing you did with the brurning paper really helped me! thank you!
