Ideas for using it

An example lesson

"The water cycle for grade 4" could become about a minute of video like this, though every lesson is written fresh. The sun warms a lake and the water rises as vapour, drawn as it is said. The vapour cools into clouds, the clouds grow heavy and it rains, and the steps appear one after another as a loop. Then the quiz: "What do we call water turning into vapour?", three options, three seconds, and Evaporation lights up. Edit the wording to match your syllabus, then play it at the start of class.

Questions

Is it accurate enough for school?

Lessons are written from researched facts and every number on screen is checked against the narration. Still, read the script before you use it in class; you can edit any line.

Can I write the quiz question myself?

Yes. The quiz is a line in the script: change the question, the options or the answer and the video follows.

Can I make the lesson in Spanish or Arabic?

Yes, in any of ten languages, with captions in the right script. Arabic and Urdu read right to left.

Does it work for maths and science?

Yes. Numbers, percentages and comparisons get animated infographics, processes get steps, and places get a map.
