7 Look at the first paragraph of the text. What theory do you think the text is going to explore?
Students’ own answer.
8 Read the text and check your answers.
Do you want to improve your study skills or write a book? Do you want to become a distinguished student? Surrounding yourself with the right colour might help!
The question of the effect colour has on the brain has always amazed scientists. Many have witnessed that red makes people feel stronger and more powerful, specifically the deep red colour.
In a study, researchers at a top university carried out tests on 600 people to see how well they used their skills. They were trying to test their hypothesis that the colour red or blue affects us in different ways.
The findings showed that people could remember details better when they looked at images against a red background, for example, a computer screen. On the other hand, they were able to be more creative when the background colour was blue.
The hypothesis is that red, which is connected with emergency and warning (fire engines, traffic lights, etc.), makes people feel more alert, and so they are able to pay attention to detail. Blue is a relaxing colour, which helps to bring out people’s creativity.
The text explores-the theory that having the right colours around you when you study might help.
9 Answer the following questions.
- How did scientists carry out their research?
Scientists carried out tests on 600 people.

Red; it makes you pay attention to detail.
- According to the report's findings, which would be a better background for someone writing a poem? Why?
Blue; it helps you to be more creative.
- Why do people respond to red with more focus and attention to detail?
Red is associated with emergencies and warnings.
- What type of red is likely to make people feel stronger and more powerful?

11 Work in pairs. Carry out the following experiments with paper. Use the pictures and the words to describe the experiments.
1 PAPER DROP
We carried out an experiment dropping a slip of paper between our thumb and forefinger. The aim was to find out whether our brains were able to react quickly enough to catch the paper before it dropped. To carry out this experiment, two people were needed one to drop the paper, and the other to try to catch it. The experiment was set up other to try to catch it. The experiment was set up by carefully placing the lower end of the paper strip between one person's open thumb and fingers, and then letting it go.
it was difficult to catch the paper as it fell too quickly.
2 COIN DROP INTO CUP
The next experiment used a cup, a coin and a playing card. The aim of the experiment was to find out what happened to the coin when we pushed the card. The coin was placed in the centre of the card, and these two items were placed on the cup, which was standing the correct way up. When the apparatus had been set up, the card was pushed across the cup, length-ways, until it fell off the other side of the cup.
The coin fell into the cup it did not stay on the card.
12 Now write the finding (explanation) of both experiments. What happened, and why?
- Our brains are too slow to send a messages to our fingers, to catch the paper when it drops
- The coin proves that objects in one place want to remain in that place. This is called inertia.
