Where does bread come from?
This resource is a primary (&/or) secondary educational video from ABC Splash.
Do you know where your bread comes from? Discover how many other foods can be made from wheat flour. This clip tells the story of wheat from the farm to the factory. See how the big machines in a flour mill make flour from grains of wheat.

How many different types of bread have you seen in the supermarket? What is your favourite bread to eat?|Have you ever made bread at home? What do you need to make bread?
What do wheat plants need to grow?|How do the wheat plants change as they grow from seeds to ripe wheat?|What do wheat farmers have to know about wheat to do their job well?|What do the wheat grains remind you of?
Take a close look at the grass that grows on your lawn or in a park. How is wheat the same or different from these grasses?|How would you explain the different types of flour that came from the milling machine? What do you think the machine looks like inside?
What other animals might like to eat wheat or other grains? Hint: you can buy wheat grains from a pet shop. Ask an adult to take you to visit a pet shop so you can ask someone there.|What would happen if you planted wheat grains in soil and watered them? Try it. Record what happens. Take some photos and make a slide show or poster about how wheat grows.
00:00:12:02NARRATOR:Do you eat sandwiches for lunch? You can put lots of yummy things inside a sandwich. And there are lots of different sorts of bread to go on the outside. You can use white bread, brown bread, multigrain bread… Have you ever tried Turkish bread? Or pita? Some people call it pocket bread because you can make a pocket in the middle and fill it with delicious things. Bread is good for us, too. It’s full of carbohydrates. Carbohydrates give us lots of energy for playing and having fun.00:01:08:13GAGA THE GALAH:I like playing and having fun too but I’d rather eat the plant they make bread out of. Do you know what it is? I’ll give you a clue! It starts with…W. Uh-huh! It’s wheat! Lots and lots of wheat! I’m going to go and eat some. See you later!00:01:37:09NARRATOR:See you later, Gaga. Wheat is a type of grass which has grains that we can eat. Each grain could grow into a new wheat plant. But if you crush the grains down into a powder instead, we call it flour. And flour is used to make bread. It’s also used to make pasta. Noodles. Cakes. Biscuits. Pies. Lots of things are made from wheat flour. So the farmer has to plant lots of wheat seeds. This machine drops the seeds into the soil with fertiliser to help them grow. The wheat plants also need lots of sunlight and just the right amount of water. Some places are too dry or too wet to grow wheat. It will only grow in places where the right amount of rain falls. As the wheat grows taller, it develops heads or ears where the wheat grains grow. And then the wheat changes colour from green to golden. Now it’s ripe and ready for harvesting.00:03:29:15GAGA:That means it’s ready for eating! Uh-oh! Here comes that big machine! I’m off! (SCREECHES)00:03:41:10NARRATOR:This machine is called a harvester. The farmer drives it around the paddock to collect the wheat grains. It’s a bit like mowing the lawn. The harvester cuts the wheat heads off the stalks and shakes them to separate the grains. The grains are stored in the harvester while all the leftover bits are dropped back onto the paddock as straw. The stalks of the wheat plant left standing in the paddock are called stubble. The straw and the stubble make a good cover that protects the soil so the rain won’t wash it away. Trucks take the wheat to a storage centre in the closest country town. The wheat is emptied into a pit. And then moved to a big storage bin called a silo. This train is taking the wheat from the silo to a special factory called a flour mill. And here, too, the wheat is unloaded into a pit. Oh, hello! Pigeons like wheat too just like Gaga the galah. Inside the mill, lots of special machines are at work. These milling machines break the wheat grains open and grind them down to flour. These machines look like they’re dancing! They shake the powdered wheat down into flour but they’re sorting the flour into different sizes or grains. The flour falls down through these socks. Look at the different grades of flour. And here’s the fine flour ready to be packed into bags. Down the slippery dip to get stacked. And wrapped in lots and lots of plastic to protect them while they travel. When the forklift has finished loading, the truck will take the flour to shops, bakeries and restaurants.
