Science Quiz - Investigating - Grouping and Classifying (Questions)

In this KS1 Science quiz, you’ll group and classify objects, spotting patterns and sorting things by properties like material, shape, or whether they are magnetic.

Fascinating Fact:

You can group magnets and non-magnets, putting paperclips and some coins in “magnetic” and plastic in “not magnetic”. Sorting like this helps scientists understand how materials behave.

In KS1 Science, you investigate by sorting objects into groups. You might use properties such as colour, size, material, or magnetism to classify things and explain why they belong together.

Key Terms

Grouping: Putting objects together because they share something similar.
Classifying: Sorting objects into sets using clear rules, such as “magnetic” or “not magnetic”.
Property: A feature of something, like its colour, material, or whether a magnet attracts it.

Frequently Asked Questions (Click to see answers)

What does grouping and classifying mean in KS1 science?

In KS1 science, grouping and classifying means sorting objects using simple rules, such as hard and soft, living and non-living, or magnetic and not magnetic.

Why do children group and classify objects in science?

Children group and classify to spot patterns and understand the world. It helps them see how objects are similar or different and to explain their scientific ideas clearly.

What examples of grouping can KS1 pupils try in class?

KS1 pupils can sort classroom objects by material, group animals by where they live, or test and separate objects into magnetic and non-magnetic sets.
