Here is a quick quiz you can use to assess your students on their knowledge of weather. It includes fill in the blank (with a word bank), multiple choice, short answer and true/false. There are questions on the weather instruments, units we use (Canada), temperature, and climate and weather.
Aligned with the grade 5 Alberta program of studies - weather watch unit
