Kareena’s chemistry – episode 3: building blocks


FunKids radio, in collaboration with the RSC, has produced a set of short chemistry snippets introducing children to chemistry- the what, why and how.

Type of Activity

Age Group


Kareena learns what chemicals are, how many there are, and how their connections and separations leads to different substances, colours, and tastes.

Skill development

Children will develop their working scientifically skills by:

  • Asking their own questions about scientific phenomena.
  • Using appropriate scientific language and ideas to explain, evaluate and communicate their findings.
  • Grouping and classifying things.

Learning outcomes

Children will:

  • Understand that all material in the Universe is made of very small particles.

Concepts supported

Children will learn:

  • How the elements are the building blocks for compounds.

Suggested activity use

The recording provided can be used at the start or end of a lesson to stimulate discussion. If used at the beginning, it could be used as a leaping-off point for a simple grouping and classifying exercise.

Practical considerations

Some of the ideas involved are not part of the primary curriculum and may be too difficult for some children to understand.

More advanced vocabulary, such as ‘elements’, ‘molecules’, ‘protons’ and ‘atomic number’, may require additional explanation.
