Every year in the spring, large numbers of frogs appear in the mud near the river Nile. They aren't there in dry weather, so in the past ancient Egyptians used to believe that in the mud produced the frogs. The problem is they didn't test their belief scientifically. 

The first step in the scientific method is to observe the world around you. For example, Newton noticed that an apple fell down, not up. The Egyptians did this a part alright; they observed the frogs. 

Step two is to ask yourself a question based on your observations. 'Why does the apple go down?' 'Where do the frogs come from?' And then think of a hypothesis: a possible answer. Objects are pulled to the ground by an invisible force. "Mud produces frogs'. The Egyptians did this too. 

But it isn't enough just to think of an answer to a question and believe it's true. You have to discover some evidence that confirms your hypothesis. So, the next step in the scientific method is to test your ideas with experiments and more observations. Galileo believed that two objects with different masses would fall at the same rate. So, the story goes, he carried out an experiment. He dropped a heavy ball and a light ball from the Leaning Tower of Pisa is and confirmed his belief. The Egyptians never did any experiments on their mud-frog hypothesis, so they never found out it was false. 

If you do an experiment only once you may make a mistake. So repeat your experiment to make sure you get the same results, and analyse your findings statistically to check they're significant. Then make any necessary changes to your hypothesis and conduct more experiments. Carefully record everything you do so other scientists can duplicate your work and check your conclusions. 

A hypothesis with lots of experimental evidence becomes a theory. A theory which has been confirmed many times is a scientific law. The great thing about hypotheses, theories and laws is that you can use them to make predictions. The law of gravity predicts that astronauts should float in space. And they do.

Chemists and physicists, geologists and biologists, researchers in every laboratory in every field of research use the scientific method. They don't accept untested observations. So they don't believe that mud produces frogs.]]> 2018-03-25 12:41:34 UTC https://padlet.com/teakay0401/95c075vxa15t/wish/245818977 teakay0401 https://padlet.com/teakay0401/95c075vxa15t/wish/245835099 Read the text to learn the new vocabulary:

Look at th picture at the bottom. It illustrates the work of a chemist. The chemist's duty is to observe (notice or perceive (something) and register it as being significant) how different substances react to each other. If the chemist is lucky enough he or she can discover (to find, to explore, to learn) a new chemical element. In order to find a new chemical element the chemist may carry out an experiment (The word experiment [ɪksˈpɛrɪmɛnt] sounds very much like one Russian word. Can you guess which one?).
However, the statement won't be enough, the chemist should provide some evidence (compare to "The police have found no evidence of the terrorist's link with the murder") to confirm (the antonym of the word "to deny") his or her discovery.

When we talk about science and technology we often mention some general truths and facts, for example, Water boils at 100 degrees Celcius. The verb tense used here is called Present Simple.

Present Simple may also be used when we talk about:
- current habits
He carries out experiments every weekend.

- how often things happen
They never talk about the significance of their discoveries.

- permanent situations
Do you research at the RAS?

- states
Are you satisfied with the progress in that field?
