Why are adults addicted to phones and how do cells double? Try our kids’ quiz

1. Clementine, 8, asks: why are adults addicted to their mobile phones?

   1. They use them for work, staying connected and for entertainment – and because they’re addictive

   2. It’s a way to talk to aliens

   3. Everything around you would freeze

   4. You’d turn to pure energy

3. Jorgie, 6, asks: how many people have died?

   1. No one has ever died; people just disappear

   3. It’s impossible to estimate

   4. Experts believe more than 100 billion people have lived and died

4. Susie, 8, asks: why did stone age people’s skulls change shape over time?

   1. Their sleeping positions squashed their heads

   2. They purposely shaped their skulls to look unique

   3. Changes in diet, lifestyle and evolution slowly altered their skulls

   4. People kept hitting them

5. Leela, 8, asks: how do cells double (or divide)?

   1. When they fill with too much water, cells split

   2. Cells divide through processes called mitosis and meiosis

   3. Cells don’t divide

   4. Cells split randomly whenever they get too big

Solutions

1:A - Adults use their phones for work, chatting and watching videos. But they are designed to be addictive, and spending lots of time on them isn’t healthy. It’s good to put them down and enjoy real life!, 2:B - The laws of physics say nothing can travel faster than light. If something did, it would travel backwards in time. Scientists believe reaching or exceeding the speed of light is impossible for anything with mass., 3:D - Scientists believe more than 100 billion humans have died since the first modern humans appeared., 4:C - Stone age people’s skulls changed shape over time due to evolution, diet and lifestyle changes. For example, early humans had larger jaws because they ate raw or tough foods. As cooking and farming developed, their jaws became smaller., 5:B - Cells divide in two main ways: mitosis and meiosis. Mitosis helps our bodies grow and heal by creating identical copies of cells. Meiosis helps to make babies – a cell divides twice to produce four cells with half the amount of genetic material.
