About This Book
This is a practical book for pupils, designed to teach the basic skills of scientific investigation and problem solving. With an emphasis on skills not facts, it is practical in approach, describing over 100 activities. No specialised apparatus is required and the investigations it covers are flexible enought to relate to any science course.

UNIT 1
Asking questions
People have always wanted to fly. Before the first aeroplane, people tried many ways of getting up into the air. They were all trying to answer the question: âHow can men fly?â
The Wright brothers answered the question when they built the first aeroplane. They could not build it from a book because it had never been done before. They had to try things out and make discoveries.
When the Wright brothers were trying things out to answer their question, they were doing science. You are doing science when you are trying things out and making discoveries to answer a question. Your question will not be as big as the Wright brothersâ but that does not matter.
Here is something for you to do.
A: Activity
Take a nylon comb and comb your hair about ten times. Turn a tap so the water runs out slowly. Hold the comb close to the stream of water.
What happens? Did you ask any of these questions
when you saw what happened?
Can I make the water bend the other way?
How far does it bend?
Does it always bend by the same amount?
Do all combs have the same effect?
Does it depend on the kind of hair?
What happens if the comb touches the water?
Answer the questions by trying things out. Try and make the water bend other way. See how far you can make the water bend , and so on.
When you are trying things out in science you are doing experiments.
Sometimes you can answer a question just by observing or measuring. Sometimes a question will be very difficult and you will need more knowledge before you can answer it.
B: Activity
Make a paper dart like the one in the picture and fly it.
Does the dart flywell? You may have asked the questions: âHow I can make it fly better?â This questions may have led to other questions: Will it fly better if I fold the paper more carefully?
Should the wings tilt forward or backwards?
Should the wings upwards or downwards?
Are some kind of paper better than others?
Does the size matter?
Answer the questions by doing some experiments. The question tellyou what you need todo. Look at the first questions above. To find the answer, make another dartby folding the paper very carefully. Fly it. Does itfly better than the first dart? You may have to fly the first dart again.
The starting point of most science is a question.
You were given some questions in the two activities on this page. Now you must learn to ask questions for yourself.
Try Yourself
C
Make a set of thumb and finger prints. To do this, put some ink on blotting paper. Press your finger on the ink and then on to clean paper.
Compare your prints with your friendsâ and classmatesâ.
Are any of the prints the same as yours?
What other questions come into your mind as you look at the prints?
D
Some people can roll their tongues and some cannot.
Can you roll your tongue? Ask your classmates to try.
What questions can you ask to find out more about this? Here are two to start you off:
How many people in your class can do this?
Can you do it if you practise?
E
Fold your hands quickly without thinking about it. Which thumb is on top of the other? Is it the right-hand thumb or the left-hand?
How many right-hand thumbers are there in the class?
What other questions come into your mind?
F
Find a partner and count the number of times ...
