What is Climate Change
You’ve probably heard people talking about climate change – at school, on the news, at home. But what is it and why is it so important?
Awesome Women Who Disguised Themselves as Men to Follow their Dreams
Throughout history girls and women have been told, ‘You can’t do that! You are a girl!’ Luckily, this attitude is becoming less common in many countries and cultures, but what did women do in the past? If they wanted to be a doctor, a musician, a sportsperson or even a soldier?
Most women put aside their dreams or practised other activities that were deemed appropriate for women. Some women protested, like the suffragettes who demanded to be allowed to vote. And a small number of women went much further. Today we are taking a look at the women who disguised themselves as men in order to follow their dreams.
The first woman to circumnavigate the world – to go all the way around the globe. Born in France, and with an interest in botany (the study of plants), Jeanne became first the housekeeper, and later the partner of a famous botanist Philibert de Commerson.
What is The Point in Learning Maths?
Have you ever sat in a Maths class wondering when you will ever need to do long division without a calculator? Or silently cursed your Geography teacher while learning about the formation of oxbow lakes? And History? That’s all in the past and irrelevant, isn’t it?
In this series of articles, we will look at some of the subjects we learn at school, and try and answer the question: What’s the point in learning maths?
Let’s start with Maths. It is a fact of life that while some people are good at Maths, for others it is a daily trial. It is, however, along with English and the sciences the subject considered to be the most important. Why? Of course, we all know that it is important to be able to count, and do simple sums, but when, in real life, do we actually use it?
Do You Have the Denim Blues?
Since Levi Strauss and Jacob Davies developed jeans all the way back in 1873, denim jeans have become the garment we reach for at the weekend. They are attractive, hard-wearing and versatile, so it’s no wonder that we spend so much time in them, and so much money on them. In the US alone about 450 million pairs of jeans are bought each year.
But what do you wear when you get bored of jeans? Is there really a comfortable, suitably casual alternative? Lissie, who blogs at GrungetoGoddess has some ideas for those who have the denim blues.
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.
