I know that our Oobleck projects have been done for awhile but I wanted to have a chance to showcase our Oobleck machines. If you remember, we had designed our Oobleck machines to deal with the properties we had discovered in Oobleck. We had discovered that Oobleck gets hard when it is squeezed, soft when it is loose in your hand, and is somewhat sticky. Using those rules of Oobleck, students needed to design a vehicle that could handle those conditions as if it was going to be having to drive on a lake of Oobleck.  Now, you can just come and see the finished projects in the hallway outside Mr. Shinness’ office, but that wouldn’t be using cool technology would it? So, here are all the finished projects in an awesome Animoto video.

If you would like to create your own bowl of wonderfully, thick and messy Oobleck, here is a recipe you can use.

Oobleck was the name given to a type of slime in a Dr. Seuss book that was capable of gumming up a whole kingdom. The oobleck the you can make for a science project isn’t gummy, but it does have interesting properties of both solids and liquids. It normally behaves like a liquid or jelly, but if you squeeze it in your hand, it will seem like a solid.

Difficulty: Easy
Time Required: 10-15 minutes

Here’s How:

1. Mix 1 part water with 1.5 to 2 parts cornstarch. You may wish to start with one cup of water and one and a half cups of cornstarch, then work in more cornstarch if you want a more ‘solid’ oobleck. It will take about 10 minutes of mixing to get nice homogeneous oobleck.
2. Mix in a few drops of food coloring if you want colored oobleck.

Finally, as we have two weeks of short weeks, I have decided to still do the spelling lists this week. However, we will do the spelling test on Tuesday of next week. I will put the spelling words on the blog tomorrow along with the link to the Spelling City site. As we ran out of time for our memory verse on Friday due to skating, we will be doing the same memory verse this Friday.

Grade 3’s have a quiz on the 0, 1, 2, 5, and 10 times tables this Thursday.
