Science is the study of how things work in the world around us. It is the study of things that are very small, very large and things so large that they can’t be measured. It is the study of things constantly changing and things that stay the same. It is the study of how things work together and affect each other. 

Scientists observe and carry out experiments to try and prove their theories. Science is not just for scientists though - it is for everyone as every day we make decisions based on what we know and see. We all interact with Science thousands of time a day, from things as complex as WiFi on our smart phones to the most simple  thing as the air we breathe and food we eat. 

Science also teaches us about life. We learn about problem solving, perseverance and that not everything works the first time.

New Zealand has produced some world renowned scientists. Our best known is Lord Ernest Rutherford who was the first person to split the atom. In 1975 Joan Wiffen was the first person to find dinosaur bones in New Zealand and Allan Wilson looked at the evolution of New Zealanders.

Science is broken up into different areas of study. Biology is the study of living things. Chemistry is about what things are made of and how they change. Physics is the study of energy and motion. Earth and Space Science is the study of the Earth, air and oceans, planets, moons, stars, comets and galaxies.
