Fruit and vegetables are an important part of the human diet. In fact, we’re advised to eat at least five portions of fruit and veg every day because fruits and vegetables contain ‘nutrients’ that help to keep our bodies healthy and working properly.
You might remember from my blogpost about why you shouldn’t only eat bread that it’s important to eat a balanced diet. So let’s find out more about fruit and vegetables and why we should include them in the meals we prepare.
Cow poo, cow pats, cow pies or cow dung – whatever you want to call the sloppy stuff that comes out of a cow’s bottom – has been used for hundreds of years to help plants grow. The farmer who lives near us puts it on his crops each year and you know exactly when he’s done it because there’s a stink in the air for days!
But exactly what is it that’s so special about cow poo that makes it good for plants?
Bees visit flowers to collect nectar and pollen which they use to make honey as a food. As bees fly around from plant to plant they pick up and drop off pollen between the flowers. This is a really important job in nature because moving pollen between flowers helps plants to reproduce (make new plants) through a process called pollination. If bees didn’t do this, then certain types of plants wouldn’t be able to make seeds.
So let’s find out more about how the lifecycles of bees and flowers work together…
Nipples are a part of the human body, found on the upper chest. Most people have two nipples (although some people have three or more!). Boys’ and girls’ nipples look similar but men’s and women’s nipples look different. So, what happens as boys and girls grow up that makes their nipples and other parts of their bodies change shape?
Air is mostly made up of a gas called nitrogen. But about one-fifth of the air (21%) is oxygen – the gas our bodies use when we breathe.
All living things need oxygen in order to stay alive but plants, algae and a group of bacteria called cyanobacteria, can also make oxygen. These plants, algae and cyanobacteria make more oxygen than they use and the extra oxygen goes back into the air. So, the oxygen is sort-of recycled, rather than used up.
Plants like trees use their leaves to make oxygen. But what if there were no trees left on Earth – would there still be enough oxygen in the air for us to breathe?
Think for a minute…
Now, what did that feel like? What did you think about? How did you make yourself think? What did you do in order to think? Why am I asking you all these weird questions?!?
Think about it – have you ever thought, before, about how you think? My 6-year-old thinks there might be a computer inside her head. Do you think she’s right?
Bodies come in all shapes and sizes, and my 2-year-old is fascinated! She likes to explore her own body when she’s in the bath. Her favourite body part is nipples but she’s noticed that Mummy’s and Daddy’s bodies are different from hers and different from each other.
So, what are the main differences between male and female human bodies? And what changes happen to our bodies when we grow up? Let’s find out!
