CHEMISTRY: Isn’t this a beautiful crystal of copper sulfate pentahydrate? Since we’ve been talking about crystal lattice structures, I thought you might like to see something different than salt!
Here are the notes from Monday – review of some the old homework (yes, I know it wasn’t your homework last night, but I thought you could use the review!!!), a discussion of the properties of ionic vs. covalent compounds and then metallic bonds. Great topics for discussion!!
CHEMISTRY 4-14-14 Ionic vs Covalent & Metallic Bonds from Tammy Skinner on Vimeo.
When we circled around the room and held hands, it was cool to see that the UFO ball lit up and made noise
The lab yesterday should that a constant flow of electrons, or electricity, can flow through metal.

Is the worksheet we did in class going to be checked tomorrow?
The electric current lab was very interesting. I didnt know in detail about how the light bulb works. Like by the current of electrons.
I can’t believe the project is finally done with! So many stressful nights put into that project, I hope it’s good
After working the worksheet today, I realized that I really needed to memorize the molecular geometry structures.
That lab that we used the bulb and batteries was intresting invwhat we learned about electricity
I enjoyed the light bulb lab we did yesterday in class. I thought it was neat getting the light bulb to actually turn on.
It’s so weird that metallic bonds are so strong because the electrons can freely move around the atoms!
I thought it was interesting how solutions of Ionic Compounds conduct electricity. Like how you can use salt water and a wire to complete a circuit to turn on a light bulb.
I found it very interesting that like bonds dissolves like bonds. This really helped me to understand why certain polar bonds don’t mix well with nonpolar bonds.
I am surprised that I missed the ricin! I thought for sure it was promethium nitrate!
After completing the project my life seems a whole lot easier!
The fact that we could qll hold hands in a circle and have electricity run through us into that ufo ball was amazing
This week I learned that in molecular geometry, the shape of a molecule affects it’s property.
I enjoyed the lAb that showed the constant flow of electrons by the light turning on.
It was really cool to learn about the different types of bonds there are. I had no idea there were that many.
The mini lab we did in class with the light bulb and battery was really neat It was awesome to see how even though you didn’t have a direct connection the light bulb still worked.
Will we have to know how to write covalent bonding with orbital notation for the test?
Comparing ionic compounds and covalent side by side helped show me how different these two really are. Ionic has an odor, brittle, hard, etc.
I find it so interesting that only the same type of bonds can break down bonds. Also, I’m so glad we have the project behind us!
The mini Lab is one of the most interesting But I’m more relived of the project being off our shoulders but I’m still scared of the grade.
It amazing how we have electrons running through our bodies all the time
It was interesting learning about all the different items in the project and how you used them. Some of the things you put, I would have never thought of.
