98 My First Dictionary of Science ACTIVITIES Now you too can play at being a lexicographer, the people who make dictionaries, and start making your first dictionary.

Collects words that you like and see if you like them because they sound good, because they remind you of nice things or fun situations, because they are heard very often or because they are very strange, or because you like what they mean, etc.

Rosa Estopà (Coord.) 99 Second game To communicate, we usually use words, but we also have other possibilities, such as gestures, facial expression, drawings, photographs, whistles, etc. Look for examples of things you can say without using words.

Try to draw the following words: television, aeroplane, mouse, ocean, chip, atmosphere, gas, justice, health; and you’ll see that some are easier to draw than others.
