My 7-year-old said she’d like some unicorn bunting to decorate her bedroom. We found some instructions online, bought some fabric and got out the sewing machine. But the cotton fabric we had bought was creased and folded. We had to make it all flat and smooth before we could draw on triangle shapes for the flags and cut them out.
So, why does fabric get creased? And why does pressing it with a hot iron make the creases go away? The answer is all to do with chemistry, so let’s find out more…
Bogeys or boogers are the bits of dried-up snot you find inside your nose. I get them, you get them, everybody gets them. You can get bogeys out by blowing your nose but my kids like to pick them out with their fingers and eat them – yuck!
But have you ever wondered what are bogeys for? Why do our bodies make them? What are they made of? And could eating bogeys actually be good for you?
Storms are a kind of bad weather, usually made up of strong winds and rain or hail. They can cause lots of damage by blowing bits off buildings and trees, causing water to overflow from rivers and streams, or making huge sea-waves that crash onto the land.
Storms happen every year and are a normal part of the weather here on Earth. But some storms are stronger than others; the stronger the storm, the more damage it could cause. So, scientists have come up with a way to keep track of them – let’s find out how they do it…
Blood is a red, oozy fluid that is found inside our bodies. It’s an important part of our bodies and we wouldn’t be able to stay alive without it. Every part of your body needs blood, from your brain all the way to your toes, and your body has to keep it ‘fresh’ so it makes new blood every single day.
My seven-year-old wants to know why blood is so important to our bodies – what is it for? So, let’s find out about what blood is made of and what jobs it does inside us:
What makes you you and what makes me me? What makes us different and what makes us the same? And why are we human beings, not cats or bees or plants or mushrooms or germs?
The answer to these questions is chemistry – a special kind of chemistry that allows life to exist on Earth…
