Grade 9 Biology investigation

Dear grade 9 students,

Bob W. is working is investigating the effect of time of day on reflex time in grade 9 students. He has asked kindly that all grade 9 students take a super quick, super fun reflex time test during advisory today and at 3pm. (click here).

You can screenshot the result or send him the number at the end of the 5 trials. Please, no practice, as it changes the results of the test. His email is muyuanwu@nanjing-school.com.

Thanks much!

Mr Mello
