Yesterday in science Keah and I did a timing thing with a ruler the rules of the first one was the ruler can not touch you hand and the results are here
Gemeve: 26.2cm,22cm,16cm,30cm and 18cm
Keah : 15cm,16.2cm,15cm,18cm and 8.3cm
Results for the ruler the just touching your hand
Gemeve: 14.5cm,7cm,13cm,12.2cm,18cm
Keah : 7.7cm,16cm,4.5cm,7.6cm,10cm
what goggle says about it
Much of the time it takes you to react to the ruler dropping is the time it takes electrical signals to travel along your nerves. Moving at about 100 meters per second, a signal telling a finger to move has to travel from your brain down your spinal cord and into your arm.
Hi Gemeve
ReplyDeleteDid you notice anything in your results? Were you better at catching the ruler when you were touching it?
Yes google is correct the signals travel along your nerves very quickly.
Well done.
