-zinced sheet steel (100cm x 10cm)
-tape
-yard stick
-two cups
-hot (60°C) and ice-water
-some fleacrabs
With these materials we build a tempratureorgan.
We build a bowl and divide it into 6 sections, each 10cm.
Then we fill the bowl up with 1cm water. On each site of the bowl we impute a cup, one with ice water and one with hot water. At last we put the fleacrabs in the bowl, watching what happens.
