WebKey Concepts: Your nervous system allows your body to react to different stimuli (external events). Reactions can be voluntary (eg: swinging a bat at a ball flying at you) or involuntary (eg: blinking at a puff of air). A reflex is a rapid, automatic response to a stimulus WebAt each temperature students should plot a graph of volume of oxygen produced against time. The initial rate of reaction can be determined from these graphs by taking the gradient of the graph at the start of the reaction after time zero. A second graph of initial rate of reaction versus temperature can = temperature. WebJan 2, 2024 · Pour 80 ml of H 2 O 2 into a small beaker. 2. Cut a filter paper disk using a hole punch. 3.
