Short videos recorded from the real CognitaSTEM app: the virtual labs, the Practice Buddy and more. Each one comes wide for YouTube, X and Facebook, and vertical for TikTok and Reels.
The Virtual Chemistry Lab
Two KCSE practicals in the real lab: lithium, sodium and potassium in water (clear to pink, and potassium's lilac flame), then a titration to the first permanent pink, with the lab explaining what went wrong when a learner goes past it. Practise every practical, again and again.
