A food additive is any substance that is added to food. Many people are put off by the idea of “chemicals in food”. The truth is that all food is made up of chemicals. Natural substances like milk, as well as man-made ones like drinks on sale in the market, can be described by chemical formulas. Some chemical substances are indeed harmful, but a person who refuses to consume any chemicals would find nothing to eat.
The things we eat can be divided into natural and man-made substances. Some people feel that only natural foods are healthy and that all man-made ingredients are to be eliminated. But many natural chemicals, found in plants and animals, are harmful when eaten, and some laboratory-made substances increase the nutritional value of food. Other chemicals have natural and man-made forms that are exactly alike: vitamin C is vitamin C, whether it comes from a test tube or from an orange.

Using Computers and the Internet in Schools
Nowadays, computers and the Internet are very important in schools. They help students learn in new and exciting ways. Here is a closer look at how schools are using technology to help students.
In many classrooms, every student has a computer or a tablet. They use these devices to look up information quickly and to learn about new topics. For example, if they are studying about the rainforest, they can watch videos, read articles, and even take virtual tours of rainforests around the world. This makes learning more fun and interesting.
Teachers are now using special programs on their computers to make learning more fun. They can create quizzes that students take on their tablets. These quizzes give instant feedback, so students know right away what they got right and what they need to study more. Teachers can also find games and activities online that match what they are teaching in class. This way, students can practice math, spelling, and other subjects in a way that feels like playing.
Homework and projects are also changing because of technology. Students can now work on group projects without having to be in the same room. They use online tools to share documents, create presentations, and talk about their ideas. This helps them learn how to work with others, even when they are not together. Teachers can check on their progress easily and give advice or help when needed.
