FUSE Spring 2016 - Page 17

N EW W o n E d S e r U W F e all h T ! Welcome to our new feature, where you'll find questions that don't really have a 'right' answer – but DEFINITELY need to be thought about. And talked about. And argued over. Which came first...the chicken...or the egg..? (Who knows who first asked this classic question? Of course we had to include it this time!) If you could redesign the egg, what shape would you make it and why? Ian, FUSE Friend What are the problems with getting an astronaut to the nearest star? Edmund, FUSE Friend Exactly how long is a split second? And how long does 'the present' last? Poppy, Fuser, age 9. Discuss these with your family, friends or imaginary friends! Send in your thoughts or anything new that's been teasing your brain to fuse@potentialplusuk.org QUIZ Half a dozen egg-related questions! (Answers are on the back cover, p20.) Q1 Do peacocks lay eggs? Q2 How do you tell an alligator from a crocodile just by their teeth? Q3 Can you label this butterfly's life cycle? Q4 It's Winter in Antarctica; what happens to the emperor penguin eggs? Q5 What are monotremes? ANSW ER – iSC IENCE: You're a rotten egg! (p5 .) Why does an older egg float ? Eggs have a tiny air pocket inside. As we mention on p 4, eggshe ll is not water tight and over time mo isture escapes and air filters in. This makes the air pocket larger, lowering the egg's ma ss and making it better at floating (more buo yant). FUSE 17
