Crime Scene Investigators hoặc Time Machines?

I have LSA's in my school. (Lawrence Special Activities, Lawrence is my school)
I'm debating to take Đội điều tra hiện trường hoặc TM(see question)

CSI:We analyze fingerprints, handwriting, air, and lots thêm to see who should stand trial!

TM:Build your ery own alarm clock, that can tickle you, play music, spray water, beat a drum, tell a joke, and tons more! We learn from SCRATCH as we program each giờ of our clock.
