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!
