Falling Sand
Pour sand and watch it pile, slide and settle. The physics are simple and completely predictable, which is exactly the point — there is no score, no timer, and nothing to get wrong. Add water to see it find its level, or stone to build something for the sand to land on.
Ideas for use
A short, contained sensory break — two or three minutes with a visible timer — can give a student a predictable off-ramp before escalation and a predictable way back. Because nothing here is scored or timed, there is no failure state to get stuck on, which matters for students who tend to perseverate on losing.
Pair it with an explicit re-entry cue rather than leaving it open-ended, and decide in advance where the break happens. If a sensory or movement break is already written into a student's IEP or 504 plan, follow what the plan specifies — this is a supplement to a documented accommodation, not a replacement for one, and it is not an intervention with its own evidence base.
