REPORT: MAKING YOGHURT

Milk goes bad quicky, but we can preserve it by making yoghurt. We use a process called fermentation to make it. In this process bacteria change the carbohydrates in the milk into acid. The acid stops other micro-organisms growing in the food.

1. We needed a vacuum flask, some fresh milk, a pot of natural yoghurt, a gas hob, a pan, a wooden spoon and a bowl for the finished yoghurt.

2. We poured the milk into the pan and we let it heat to 30ºC. We stirred the milk and we didn't let it get too hot!

3. We let the milk cool a little. Then we added the natural yoghurt.

We stirred the mixture for about two minutes.

 

4. We put the mixture into a vacuum flask and we closed the lid.

 

 

5. We waited for twelve hours.





6. We opened the flask and we poured the yoghurt into a bowl.

 

7. We kept the yoghurt in the fridge.

ENDANGERED ANIMALS

Do you know what it means if an animal is "endangered"?

 

It means that there are not many of that type of animal left in the world, and one day, they might all be gone, which is called becoming "extinct".

 

How do animals become extinct?

• They lose their habitat, which means that there's nowhere for them to live. For example, many animals make their homes in the rain forests that are being cut down. Once all the trees are gone, there will be nowhere for these animals to live, so they will die.
• Some animals, like chimpanzees, are becoming extinct because people kill them to eat them.
• Animals are taken from the wild and sent to circuses and zoos, leaving fewer animals in nature to carry on the species.
• Some people shoot animals for fun. This is called "big game hunting", and if enough animals are killed this way, some animals could become extinct.
• Elephants are taken from the wild and forced to drag heavy machines to help people cut down forests. This is called "logging".

BE ACTIVE!

Here are some ways to keep your bones, muscles and nerves healthy:

• Always warm up before you exercise.

Cold muscles are easier to damage than warm muscles.

• Do some physical exercise every day.

It keeps muscles and bones strong and healthy.

• Wear a helmet and safety pads when you cycle, rollerblade or skateboard.

They protectyour brain and your joints.

• Eat a healthy diet with lots of different food groups.

Bones, muscles and nerves need minerals, vitamins, carbohydrates, protein and fat to grow and work well.

• Drink a lot of water when you are thirsty.

Your body and brain need water to work well.

• Exercise your brain every day.

If we don't use our brains, they don't work so well.
