CHEMISTRY – Hey guys, here’s the lecture from Monday on the scientific method. Thanks for being patient with the finicky computer! I know you’ve heard it for umpteen years, but make sure you can APPLY what you’ve learned about the scientific method. Honors Chem – did you finish investigating Oobleck today? Kind of odd homework, hum? Regular Chemistry – you’ll have your chance with Ooblek tomorrow! (And I’ll give you the lab sheet tomorrow in class.)

Hi Ms. Skinner! I know we already turned in the work sheet for the oobleck experiment, but I was wondering, what state of matter is oobleck?
Katherine – Great question! Did you check out the post from today? And check out the new video down in the Vodpod!
Oh I see! Is it the video about the non newtonian fluid? So the oobleck is non newtonian? Thank you I think I understand now!
is oobleck two states(liquid and solid) or one state?
Cornelia – Great question! Based on your experiment today, what do you think? 🙂
That oobleck experiment was really fun/cool!! I had a blast!!!
When will the chapter 2 test be??
Mrs. Skinner I really like the oobleck video. It’s very funny. I did want to know what are we going to use the calculators for and what type should it be for chemistry?
Brandon – You need a scientific calculator; one that does scientific notation, but not a graphing calculator. Don’t spend a lot of money on it though. And I’m glad you enjoyed the lab!
Your podcast works. It’s really helpful. hope you keep this going some things i had forgot. And your podcast has help me remember things i forgot or didn’t know. Thank you!
Brandon – Glad it helps!
Sorry, forgot to change my name. Thank you for posting the podcast, Ms. Skinner! It’ll be really useful! I enjoyed Oobleck lab! 😀
Hey Ms. Skinner! Well since you showed part of the Oobleck video in class today, I really wanted to see the rest so as soon as I got home I re-watched it. Thanks for letting us do the lab. I really enjoyed it, and thanks for posting. :3
And why does adding numbers or food coloring to things make people listen/want to pay attention/be careful?
Adding food coloring makes people pay attention because it looks more threatening than a clear fluid. It’s all about your perception.
I think adding color to things makes them more fun. Not threatening.
Josi – Me too! 🙂
Judy – It’s cool, isn’t it! And about the last…….go figure trying to understand human nature!
Is Oobleck the only non-newtonian fluid?
Nicolas – What about quicksand??
Hey how often will you offer help sessions this year? I will do my best to attend them every time they are available.
Hi Mrs. Skinner,
I enjoyed the oobleck lab. It really made you think about if it was a solid or a liquid.
The oobleck lab was incredibly amusing. If only we could have walked on it like in the video.
🙂
I liked the oobleck video. It’s amazing how they can walk on water.
Do you know when the next test will be?
Mrs. Skinner is oobleck a material in silly puddy?
Corey – Oobleck is really just corn starch and water! Go figure!!
