I found a simple interactive that is useful when introducing in Year 5 the idea that many different resources are used to make a good or provide a service. It is on a US website and hence has some wording that differs slightly to the wording used in Australia but it can be easily understood.

It could be used as the ‘hook’ for a series of lessons about the three types of resources.

The other two interactives in this collection are not as useful for this purpose.
