OOBLECK and a little Halloween Party flashback!

Oobleck, oobleck, oobleck!  That is the substance that was all over my lils' clothing and hair on Friday (we were able to at least wash it off of our hands/arms)! OOPS!  However, it should have washed off of their clothes pretty easily.  Oobleck is simply 1 part water to 2 parts cornstarch and a little food coloring for a fun twist.  Oobleck is a non-newtonian fluid which means it acts like a liquid when poured, but like a solid when a force acts upon it (like when you punch your fingers in it).  Pretty neat stuff!  It complimented the end of our matter chapter in science since it takes on the properties of both a solid and liquid.

First, we watched a youtube video of two Spanish talk show hosts walking (more like running!) across a pool of oobleck!  Go here to watch the video... or watch it on here (hopefully this works!).

Their little minds were blown!  They kept asking, "What?!  How are they doing that?  What is that stuff?"

Then, I explained what was in the pool and that we were going to make it.  Of course, their next question was, "Are we going to run across it too?!"  I had to break it to them that I did not buy enough cornstarch to make a pool of oobleck... "awwwww....."

I made a batch underneath the document camera so that it projected on the SmartBoard for all to see.  Next, I made two more batches of the stuff in big plastic containers (the kind that you put shoes in and slide under the bed).  I split up the class into two groups of 11 and let them stick their hands in the ooey, gooey mixture.  Needless to say, things got a bit messy...  I forgot did not take pictures of the kids experiencing the oobleck, but here are some pictures of the ingredients I used and me playing with the original oobleck batch in case you have never seen it before.

I bought the cheapest brand of cornstarch. :)

If you look closely, you can see that the cornstarch package exploded all over the document camera and the cart... oops! 

 Hard/solid-like when I try to grab it.  I'm using all of my finger muscles(?) here.

Finally, I was able to pick up a chunk, but alas, it instantly turned into liquid...

Back into the bowl it went!

So, if you would like to make this in your classroom, it is super easy, but can get messy.  I would lay down a beach towel or old plastic shower curtain, something that you can easily clean up after all of the fun is over.  That is the lesson I learned from this little activity, so I am passing on my new knowledge to you! :)  

Now, onto our little Halloween Party flashback!  First of all, thank you so much to my homeroom mom and all of the moms and grandmother who came to help out!  I do not know what I would do without you all.  Here is a picture tour of the Halloween station games/activities that we enjoyed that day....

Halloween Bingo and Halloween erasers as bingo markers (all from the Target Dollar Spot!)

Skeleton ball toss


Halloween corn hole toss!  I believe my homeroom mom made it.

Paper towel roll ghost bowling with a plastic pumpkin!


Every game had a little treat/prize as well!  The kids had a blast!!

And not to disappoint, the two kindergarten teachers and I (in the middle) collaborated again this year... The 3 Blind Mice! Thank you pinterest! :)

Well, that should do it for now!  It is off to bed for me.  After a day of making a rare appearance at the gym, laundry, figuring out how to renew my passport so I can go on our honeymoon in June, and working on my research study paper for my grad class, my brain has had enough.  I hope you all have a great week!  One more week and a few days until a lil Thanksgiving break! :)
