To celebrate Science Week we have been super lucky to have our very our Professor Science Pants (impromptu name) visit us every day! Each day, Professor S for short comes bursting through the door after morning break looking mad as a hatter and ladened down with all sorts of science equipment... strangly Ms Murray is nowhere to been seen for the next hour and a half??? probably enjoying a well earned extended coffee break we think...
So once the children and calmed after overexerting themselves with excitement here what Professor S has been doing with us in our class over the last two days...
Professor Puffendorf's Secret Potions
Growing salt crystals...
Our first experiment was a group one. The children watched as Professor S add a magic ingredient (table salt) into the steaming solution (very hot water add some green food colouring to make it more potion like)... we have to be extremely careful because one drop too much and we would be blown to smithereens... but too little and the crystals wouldn't form right. So the children watched in suspense as bit by bit we made the correct solution without resulting in explosions. Pouring just enough to cover our paper squares we have left it to dry over the next view days. Fingers crossed we will end up with something like these!
The next experiment was more hands on for the children... colour dissolving using skittles. I used blotting paper in this one but any paper would work. The fun part here was using lots science equipment like tweezers and magnifying glasses. Everyone felt like a mad scientist!
These will be nice and colourful to bring home or stick into the scrap books...
To start us off I played this... you don't get more inspiring than Wintergatan Marble Music Machine!
This was a really interesting lesson for the children, especially now that we have started out letter sounds. We explored what sound is reading this book, learning about vibrations and sound waves.
Exploring different fillings in our shell maracas, we talked about loud and quiet sounds. Adding paper balls only made a very weak sound because the sound vibrations weren't strong enough. But by adding dried beans we made a loud sound, because of the really strong vibrations. Each child will get to make one and bring it home on Friday.
Most of these experiments were suitable to add to their Aistear play... although at the end of aistear all the skittles had disappeared and there were no colours on the paper sheets???... perhaps it was an invisible potion?
Inspiring through story...Wendell's Workshop
Working together to plan our own robots!
You can never have enough junk according to Wendell!
Fizzing Test Tubes!
Today's experiment involved some steady hand and a little messy work... ingredients included corrosive acid and exploding powder with a little drop magic potion...
At one point the professor shook the potion to see what would happen and we had a real live explosion, there was magic potion splattered across the walls of the room... opps. We'll leave that to Ms Murray to clean up!
You'll find these and lots more of experiments Professor S favourite science experiments here!

P.s it's not too late to raid the attic for that old science coat!!
