Kia Ora Bloggers, How has your week been so far?
Today we did another mini science experiment but this week it was about our senses, in particular touch. We got into pairs and then half of the class ( my half ) got given a kit, inside was a 15cm ruler, 4 colored pencils, 1 normal pencil, 1 rubber, 1 pencil sharpener, and one caliper (to poke). Our task was: There was a person A and a person B, Person A started off blindfolded while person B poked, we had to do it with 2mm, 5mm, 10mm, 15mm, and then 20mm we had to record how many pokes we felt from the caliper. After this, we finished and moved to the other person. From our data we collected, we think that 15-20mm were the times you mostly felt the 2 pokes and not the 1, with the 2mm we didn't feel the 2 pokes at all.
Have you ever done something like this? Do you know what a Caliper is? or have you ever used one?
Please leave me some feedback and Maybe check out my other posts. Blog you later!
