Process: - Put water in an ice cube tray - Put the ice cube tray in the freezer - Wait 5 to 6 hours - Take the ice cube tray out of the freezer - Bend the tray slightly to get the ice cubes out and into a drink. Perturbation hypothesis: suppose freezer is working effectively happens, how will it affect MORE ice cubes being made. Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: yes

Process: - You breathe in - Air goes through all the little branches in your lungs to fill up the air sacs, or alveoli - Oxygen goes through the walls of the alveoli and into the capillaries - The oxygen goes into the bloodstream - Oxygen is left and carbon dioxide is picked up - You breathe it out through your lungs - Perturbation hypothesis: suppose the person is breathing oxygen through a mask happens, how will it affect more oxygen reaches the capillaries. Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: yes

Process: - An owl leaves his nest - The owl flys out into the night - The owl looks down at the ground - The owls keen eyesight allows him to see in the dark - The owls sensitive hearing allows him to locate hidden prey - The owl swoops down - The owl catches a mouse in his talons. Perturbation hypothesis: suppose there is more food for them to eat happens, how will it affect the owls will have less to eat. Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: yes

Process: - A bird picks a spot high spot, often in a tree - The bird collects bits of sticks and grass - The sticks and grasses are placed between support branches - Leaves, mud and spider webs are added to the sticks - The mud, leaves and webs glue the sticks together - The solid nest supports the eggs - Perturbation hypothesis: suppose the cracks are smaller so they hold less water happens, how will it affect less leaves will stick together. Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: no
