"Google Forms is great for collecting data. Students can report their activity, how many laps they ran, etc.. Attaching Forms in Google Classroom gives you a count of who has filled out the form."

Keeler, Alice. "15 Ways to Use Google Classroom in Physical Education." Teacher Tech. 30 Oct. 2015. Web. 21 Feb. 2017.

Forms are also great for tests and quizzes. Forms will grade those questions that are not open-ended and can provide students with instant feedback.
