On Tuesday the Science Boffin Vicki visited Broadbent Fold as part of British Science Week.

During the assembly we watched paper disappear when she lit it on fire - this is special paper called 'flash paper' 

Miss Harvey was kindly volunteered to have water tipped on her head... luckily the water had disappeared from the cup. This was because slush powder was in the bottom of the cup- this is a special powder which absorbs water. This is what is used in disposable nappies. 

She also made elephant toothpaste (for their smelly breath) by mixing together ingredients to create an exothermic reaction- when hydrogen peroxide breaks down into water and oxygen it gives off heat. 

We used Bernoulli's air flow principles to show where a stream of air goes using a leaf blower and toilet paper.

We finished the day with a very exciting rocket launch. Unfortunately the rocket got stuck in a tree on the way down!!

We have had a very fun-filled day with lots of learning!
