It has been over a week since we set up our bouncy egg experiment.
We were excited to discover if our egg would now bounce!
We took the egg out of the vinegar and discovered it had NO shell left. It felt very spongy and bounced in our fingers. We could see the yolk too.
We took it outside and tried to bounce it. We did a little bounce first and it worked so we tried a bigger bounce ..... but it burst!!

Is it SCience or Magic?
Today we did a really cool science experiment.
Mrs Pelham put some water in a bucket. She told us she was going to spin it around.
We had to predict is we thought she would get wet.
Some of us thought yes and others thought no.
Then we did the experiment.
WOW, Mrs Pelham didn't spill a drop!
We had a turn too......all of us managed to do the same! No water was spilt, only Finn got a tiny bit wet as he stopped spinning the bucket!
Mrs Pelhan posed this BIG QUESTION to us
Why didn't we get wet?
Was it Science or Magic?
You did it too fast and the water needs some time to drop out of the bucket - Bryn
The wind was pushing against the water to make it go back into the bucket because we were spinning it fast - Tiaan
When we spun it the air got into the water to stop it from getting out - Bina
it didn't spill because you were spinning the bucket too fast. When you stopped it didn't come because you were swinging it too fast - Ahsley
Gravity stopped it coming out - Charlotte
when the bucket was spining the water was spinning too - Poppy
there was gravity, without gravity it would float in the air and come out of the bucket - Emma
the water stayed in because we swung it too fast and also it meant all the air made it stay in almost like a feather except it's like water in a bucket and you twirl it around - harper

May the Force be With You
Today we learned about forcces.
We discovered that if you drop things they fall at the same speed even if one is heavy and the other is very light. This is because gravity pulls them to ground at the same speed.
We also discovered that things like feathers take longer to land on the ground becuase they catch some air and that slows them down.
We dropped lots of things to test this theory. We discovered it is true! Even when dropped a tiny crayon and a huge, heavy drink bottle they landed at the same time!
We had a competition to see who could make their piece of paper stay in the air for the longest time. We discovered that the greater the surface area the slower the paper fell.
Have a look at the great clips here.

Dancing Raisins
Today we did a experiment where we made raisins dance!
It was a lot of fun.
We put lemonade in a glass and then added some raisins.
We enjoyed watching the raisins bob up and down in the glass.
We discovered this happened because the carbon dioxide in the drink made bubbles on the raisins. Then the raisins floated to the top. When the bubbles popped the raisins sank again.

Acid or Alkaline?
Today we used Red Cabbage Dye as an indicator.
We discovered that this means the dye changes colour depending on whether something is an acid or an alkaline.
We had so much fun adding all sorts of things to our indicator dye.
We mixed different things and saw different reactions.
I LOVED listening to the excitement as the children did this experiment and seeing their faces as they made all sorts of discoveries. I also loved that they could explain things.
I have captured some of this session on video- while the quality of the movie isn't great, it is SO worth listening to hear the fantastic conversations that were going on in our room during this lesson.
The children discovered that acids turned the indicator dye bright red and alkaline turned it blue. They also discovered that they could make chemical reactions in their cups!

Mentos Geyser
We got together with the whole Year 2 team and did a very cool and rather explosive experiment!
We all lined up around the grass edge of the 'u'
Mrs Pelham put a whole packet of Mentos Lollies into a bottle of coke!
Look what happened!!

Making sherbet
We each got a bag and we added
baking soda
citric acid
tartaric acid
raro
icing sugar
We shook our bag to mix the ingredients.
We tasted the citric acid and tartaric acid.
super sour - Briannah
sour - Charlotte
yum, yum, yum., yum, yum - Lily
spicy - Emma
double hot - Bina
stupendously sour- Riley B
super duper lemon luper sour -0 Harper
really, really, really sour - Netahsa
Super sour - Cilliam
When we taste them all together we think
it will fizz on your tongue - Poppy
