# Investigating - Changes over Time

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 data to investigate changes over time.

In science at school you have looked at simple data to investigate how things change over time. Plants and animals grow. The seasons bring different weather. The nights get longer in the winter and shorter in the summer. This quiz is all about using simple data to investigate how things change. Can you say how much they have changed over time? Can you say why they have changed? Have a go, and see just how many you can get right.
