Which sample keeps water out? — Apply and reason
Read with an adult. You can say, draw or write your answer. Use safe large objects when asked. Take one question at a time.
Read before answering
An adult's practice test uses equal-sized paper and plastic samples on a tray. Paper gets 4 drops; plastic gets 2 drops. Both are checked after 15 seconds. Supplied result: water appeared beneath this paper but not this plastic. This is not your own experiment. Any real test needs an adult, tiny water amounts and no electrical devices nearby.
