1. Throughout this activity, one of the main scientific principles can be related to the nervous system and the concept of having a reaction time through different means of stimuli. Individuals interacting with the board are exposed to a light, sound or touch stimulus. When the stimulus is created, there is a signal that is first formed within the peripheral nervous system (PNS). The PNS is consisted of nerves that connect the brain and spinal cord to the muscles of the body, sense organs, glands and other tissues (Widmaier et al, 2014, p. 139). That signal, then progresses to the central nervous system (CNS), which is composed of the brain and spinal cord. Once the signal reaches the spinal cord, it then gets transmitted to the brain that…show more content…
One of them is Unit A: Nervous and Endocrine Systems within Biology 30. The general outcomes focus on how the nervous system controls physiological process and its contribution to homeostasis (Alberta Education, p. 51). Specific outcomes of knowledge include the concept of the reflex arc, transmission along a synapse, receptors and even the transmitters involved in the process. For a reaction time to occur, all of these processes happen within the human body. 30-A1.2sts states to analyze experimental evidence regarding the influence of anesthetics, drugs and chemicals, natural and synthetic, on the functioning of the nervous system and relate this to addiction theories (p. 52). The worksheet will heavily be focused on the influence of drugs and can be discussed further in class. Additionally, the major functions of the system were introduced in Biology 20, as 20-D3.1sts further states that the goal of science is to create knowledge about the natural world, as to provide the negative and positive attributes of drugs. To meet the requirement of Performing and Recording, students will conduct investigations into relationships between and among observable variables and use a broad range of tools and techniques to gather and record data and information [30–C3.2s] by having the choices of the internet, textbook resources,
