We had lots of fun with our pumpkin project.  On Wednesday we measured our pumpkins with unifix cubes (which was a little tricky because a pumpkin is round and the cubes are flat) and guessed and checked it’s weight and whether it would sink or float.  We were amazed that all of our pumpkins floated, even the 22 pound pumpkin!  On Friday we cut open our pumpkins to find out how many seeds were inside.  We also designed a jack o lantern face, and with the help of our wonderful moms, carved our designs.

What’s the Matter?

We learned all about matter this week.  First we observed the three types of matter in balloons.  Then we popped the balloons to see what would happen.  The solid kept its shape, the liquid spilled everywhere, and the gas disappeared (with a LOUD pop!).  Today we talked about molecules.  We pretended the balloons were molecules to see what would happen when we shake them up.  The tightly packed molecules hardly moved, but the molecules that had more space bounced around like crazy.  We found out that the molecules in a solid are tightly packed, but the molecules in a liquid and gas have more space to move around (which is why they don’t keep their own shape).

OREO Project

Our class participated in the annual OREO project.  We had lots of fun trying to stack the tallest Oreo tower. 

IMG_1784 IMG_1782 IMG_1775 IMG_1777 IMG_1780 IMG_1781 IMG_1776 IMG_1779Our tallest tower was 31 Oreos tall!  Our class average was 23 Oreos tall.  You can check out results around the world here and there’s even a map that shows you who participated. Check it out!

Throughout the day we did other fun activities too.  We graphed our Oreo stacking results and found the range, mean, median, and mode.  We also analyzed the nutritional information.  Our class talked about all the different ways to eat an Oreo, graphed our poll, and we each wrote an informational book on how to eat an Oreo.  It was a super fun day!
