Then and Now: Preparing for the summative.


We began preparing for our summative next week.  Throughout this unit, the children learned that many things were done by hand in the past including cleaning. Referring to the central idea that there are similarities and differences between the way people lived long ago and the way people live today the children will develop a cleaning machine so we won't have to clean by hand.

Wendy began the week by showing the children a Cat in the Hat video

She asked the children to pay attention to the end of video where they will see a special invention, one that she wished we had at the daycare. At the end of the movie, the children were excited to share their thoughts about the machine.  Wendy did a human graph - would you want to clean or have a machine do the work.  It was unanimous, the machine won. Next week we will build the machine. Esme said "I cant wait for next week!"

To build a machine we needed to see how machines work. We spent Wednesday experimenting with simple machines and making a connection to how our machine would operate.  Brainstorming, the children came up with some ideas for our machine:

arms for picking up garbage - Tyreese, Esme, Byron
hook to grab things - Esme
wheels to help it move - Byron
chopsticks on the arms to pick things up - Jayla
handle to pull it - Grace
a hinge to attach the parts - Oliver
bag for garbage - Esme

Now we have an idea of what our machine will do, we drew a picture of it. We examined all the items that have been donated to see what we could use. We found:
lids for wheel - Oliver, Grace
chain for a handle - Grace
string for handle to carry it - Sophie
hose for the arms - Oliver

Working together next we will make a cleaning machine.

Verdi: Catapults

Verdi, a young python, does not want to change.  The last thing he wants his to turn from his beautiful yellow to boring green. Verdi tries to change his colour back to yellow by scrubbing his skin and then covering it with mud. Nothing works.  He notices that the sky is bright yellow just like he used to be. Verdi launches himself from the treetops certain that his flight will change him back to yellow.



How did Verdi fly through the air? What a great opportunity to learn about catapults. Elastics and popsicle sticks were the only materials need to build a catapult.  First the children, used plastic snakes to sail through the area.  It was delightful to hear the excitement and the laughter as the children made  their "Verdi" fly.




I asked the children which would travel farther; a plastic snake or a pompom.  Most of the children though the heavier item, the snake, would travel a further distance.  The children were amazed at how far and how high a pompom could move.
