Year 4: National Science and Engineering Week


 
 
Today, we celebrated National Science and Engineering Week with three enjoyable investigations:
1.      Floating floors – we saw how air (a gas) fills shapes when we created a platform out of balloons and cardboard. We predicted the balloons would burst, but even one balloon supported the weight of one person, until the rubber split under the pressure!
2.      Flying cornflakes – by the end, we understood all about levers and fulcrums by firing cornflakes up to an incredible 4m, 16cm!
3.      Spaghetti Towers – in groups, we attempted to construct the tallest tower we could using only dried spaghetti and marshmallows. We thought the towers could have been bigger if the sun hadn’t have melted the marshmallows!
