How Much Sleep Do Kids Need?

Julianne Robertson investigates the world of snoozes, forty winks, cat naps and snoring. What is SLEEP, why do we need it, and how much sleep do kids need?

A couple of nights ago I was feeling really, really tired, so I went to bed early. I slept soundly, without even dreaming, until about 5am, when I woke up. It felt like I’d only been sleeping for about 5 minutes! After that, I fell back to sleep but had lots of vivid dreams and when I woke up a couple of hours later, it felt like I’d been asleep for a long time. After all that I still felt well-rested and was ready for the day.

All this made me wonder – what IS sleep? Why is it that some nights we feel like we’ve had a really good nights’ sleep, while other nights we still feel tired when we wake up in the morning? Here’s what I’ve discovered about sleep…

A Day In the Life Of…a Biologist

Ever wondered what being a biologist might be like? No two scientists work days are the same but I’m going to take you through my typical day to give you an idea

7 AM: I get up and eat breakfast (toast and a cup of tea) before travelling to work.

8 AM: I arrive at work (this is early for scientists, most of my workmates arrive at about 9 AM but I like to get up early!) After checking my email the first job of the day is to turn on the microscope above.

The plant root surface is covered in root hairs. This is what they look like under a microscope.To get an idea of the cells, les than 1mm of plant root can be seen in this image

It is similar to microscopes you may have used at school but with a few added features including a special camera. I am fascinated by plants and in my research I am trying to find out more about how some plants (including peas and beans) can form a friendly relationship (known as symbiosis) with soil bacteria, which provide nutrients that the plants need to grow. I use the microscope and camera to study living cells in plant seedling roots (where the symbiosis is set up).

10:30 AM: Tea break and seminar. I have a tea break with some of my workmates and then go to a seminar where other scientists talk about their research and we discuss it afterwards. Seminars are a great way to find out what experiments other scientists are doing, and to get ideas for new experiments to try.

12:30 PM: I have lunch with my friends.

1:15 PM: More experiments. For some of my experiments I have to grow plants in greenhouses. Today I visit to check on my plants and collect some to take measurements. This involves digging up the plants and cleaning them to look at their roots. This is fun, but messy!

3:30 PM: Afternoon tea break.

3:45 PM: Data analysis. I spend the last part of the afternoon drawing graphs of the data I have collected today and thinking about what it shows (does it answer the research question? Do I need to do further experiments?). I also spend some time reading research articles to find out about experiments other scientists have been doing.

5:30 PM: Hometime! Once I am home I have dinner and then relax.

One of the things I love about being a scientist is the feeling of discovering the “unknown”. The experiments I carry out reveal little details that when combined with other scientist’s data can help us build up a picture of how the plant-bacteria symbiosis is set up so that pea and bean plants can get the nutrients they need to grow. We hope that this knowledge might be able to help improve farming in the future.

About the Author

Sarah Shailes is a plant scientist working at the John Innes Centre, Norwich, UK. She studies how some plants can form a friendly relationship (symbiosis) with soil bacteria, which help the plants gain nutrients they need to grow. When she isn’t in the laboratory she enjoys knitting and hiking, and helps run a local Brownie Guide unit.

The Indian Princess Suffragette – Sophia Duleep Singh

You’ve probably heard of the Suffragettes, who fought for women’s rights, but did you know that an Indian princess was one of the leading campaigners in England?

I, Coriander by Sally Gardner – Book Review by You

This book is set in 1649, just after King Charles 1st had been executed. At the back of the book there are some historical background notes.

It is really hard to describe, because although it is set in a real time from history, it moves between two different worlds, it is unlike any book I have read before.

It is the best book I have ever read, I couldn’t put it down and read the 300 paged book in two days. It is packed full of mystery, magic and adventure, and history, with the slightest bit of romance.

The story unfolds through the eyes of six year old Coriander, who is almost 20 by the end of the book. One of things which is fun seeing change, is Coriander’s fear of the stuffed baby alligator in her father’s study, it holds the key to the cabinet in its mouth, and at the end, it comes alive (just like she had feared all along) it saves her-I can’t tell you how because it will spoil it!
The imagery throughout the novel is beautiful, and everything is described in great detail. Here is an example:

” Everything in the room was covered in a layer of thick dust. The curtains that the sun had been badgering were now no more than a mass of spiders webs. The bedroom covers were all torn and tattered, feathers split from the mattresses, and the wash basin was cracked and broken as if long abandoned. It was a room of rags and feathers, nothing more.”

The book has a fairy tale quality to it, because of the language Sally Gardner uses and the events of the story.
The characters are larger than life and dramatic, and at times frightening.
This novel’s ending was satisfying and felt complete. After reading this book I felt inspired to write a story set in a time from history also. One of my favourite things about the book, is how Coriander stands up for herself.
I highly recommend this book, I will definitely read it again!
I rate it 10/10, and would recommend to age 9-14
