Becoming Engineers

Learning to measure with one of his many big sisters :)

This morning we tried the balloon, straw and string experiment to demonstrate Newton's Third Law: to every action there is always an equal and opposite reaction.

 Fun with magnets.

And then we tried our hand at problem solving.  The kiddie each wrapped an egg in various protective materials to see if they could keep it from cracking when dropped from a height.

The Boy wrapped his in foil, cling film, cotton wool and more foil...



...it cracked...

...but playing with the broken egg was super fun.

Ballet Girl wrapped hers in all sorts...

...and so did Monkey Girl...

And they both worked!


I loved Panda Girl's one as she used trapped air to help cushion her egg.  She was gutted that it cracked.  Never mind!

We also did some problem solving with ice cubes.  Our control ice cube sat on a plate in the classroom

Our experimental ice cube was wrapped in foil and and put inside a picnic bag with a cooler lining and placed next to a freeze block,  After the control ice cube melted we checked on our other ice cube and it was almost still completely frozen.

Our third problem solving of the day was to find the slowest way possible for a marble to run down a slight incline.  The photo below shows Ballet Girl's and The Boy's teamwork and it worked extremely well, with the play-do for friction and the shallow slopes to slow the speed.  This was exactly how I would have gone about this task also...

...but Monkey Girl and Panda Girl came up with an ingenious idea...

...they put their marble inside a slightly inflated balloon and used cut straws stuck in play-do to slow the marbles descent.  It worked hilariously well!

 After lunch the children spent over an hour playing football in the garden.

 The Boy learnt the sound ch.


And Panda Girl worked on her Multiplication and Division workbook.

Today the children also attempted pictures in the style of Fernand Leger, visited the library and went to Sea Cadets.
