Boo as you know was placed into our sink or float container and we are watching it decompose. Here is Boo several days after being placed in the container. We all think it is gross but not a day goes by where Boo isn't examined...
We placed blue tape at the water level without pumpkins. We then made predictions about each pumpkin . Would it sink or float ? And Would the water rise above the blue tape ? The children observed carefully and we marked each pumpkin's rise in water level. They realized the heaviest pumpkin had the highest water level.
Part of the integrated focus of room 24 included some science this week! During Pirate club we are studying the Unthkinkable Brain Eater. One way to understand this Unthinkable and defeat him is to learn more about the brain , how to grow neurons and how our attention works. For our first lesson we watched Ned Neuron, read the book, Your Fantastic Elastic Brain and made Neurons!
We learned to grow these important brain structures we needed to learn or try new things, not give up even if we make mistakes, keep practicing and stay curious!
The next day each child wrote how they planned to grow more neurons.
Our experiment to observe what will begin to break down faster begins. This three section visual mini compost bin includes thermometers to monitor changes in soil temperature. We added our three categories of waste , our worms , a bit of water and waited...
In June as we packed up the room we took one final look.
The apple and banana were no longer visible and indeed had broken down a great deal. The paper napkin was gone but bits of the straw remained. No change with the plastic which was expected.
We began our unit of the 3 Rs- Reduce, Reuse and Recycle with the movie Wall.e . Wall.e faced a problem on Earth, the humans had left Earth leaving robots behind to clean up all their garbage and waste hoping to return later.
After watching the movie we studied categories of garbage, what happens to our waste & and the problem of plastic in our oceans. We learned about the 3 Rs and observed the waste during lunch in our cafeteria.
Next , we moved onto the F.B.I and ways these decomposers help break things down. The F.B.I. ( fungus, bacteria, invertebrates) helps break things down and create healthy dirt.
This week we investigated the I- Invertebrates . Specifically , worms and Banana Slugs. We were also learning two songs , Banana Slug and The F.B.I.. So much learning and fun... The banana slug race was full of cheering, learning and giggles.
No Invertebrates were harmed and all were returned to their habitats with stories of gentle children.

As the children work on their science fair projects, it was time to model the steps in a fun and engaging way. A generous colleague provided me with a few suplies and inspiration.
Day 1 - We practiced flipping , noticing and generally had some fun. The children noticed that the amount of water, where they expected it to land, force, type of flip etc. made a difference on the success of their bottle landing upright. But they were having to much fun to experiment in a systematic manner. SO, Day 2 - I posed the question-
How much water does it take to make it easier to flip a water bottle and have it land upright?
The experiment was to flip their bottles using two different amounts of water ( 125 ML or 1/4 full) or ( 250 ML or 1/2 full.) They were to tally the number of flips until their bottle stood upright on their desk. This data was then recorded onto a large GO chart for analysis.
I had the children record their hypothesis (smart guess ) on which amount of water would make it easier to flip & have their bottle land upright.
I then modeled the experiment step by step stopping at the class data collection & conclusion section. I recorded my data. The children were generally impressed that I could flip a bottle and have it land upright several times.
Now the fun began!
The children began filling bottles and putting their caps on TIGHTLY. ( I just couldn't stress that enough . ;-) They giggled as I exaggerated water everywhere and my stern drippy look.
I have included a few videos to show engagement, focus and shouts of excitement.
