This was a very quick video I created using sparkol (which is the online version of videoscribe). This app is really simple and easy to use. It can be adapted for any topic (as you can use the pictures already on the app or upload your own).
I would use this with both KS1 and KS2 as I think with help KS1 would be able to create a great piece of work. KS2 on the other hand, would be able to use this as a presentation tool to present their ideas, topics or findings.
It is a fun and engaging way of putting your work together:)
