Investigating - Simple Tests
How could you find out which colour is most people's favourite?

Investigating - Simple Tests

This quiz addresses the requirements of the National Curriculum KS1 Science for children aged 5 and 6 in years 1 and 2. Specifically this quiz is aimed at the section dealing with using simple tests to investigate.

How can you answer questions in science? Some questions are too hard for you to answer but some are more simple. Where will you look for answers? How will you investigate your ideas? How can you test different materials? What can you use? There is often more than one way of answering a question in science. Using books and the internet to investigate is a good thing, but it is even better to do simple tests to find out for yourself, if you can.
