20-D2.2s

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:     •measure blood pressure and observe blood flow in capillaries in an organism or through demonstration in a virtual laboratory (PR-NS2)(PR-NS3)     •determine the morphology and abundance of cellular components in a prepared human blood slide (PR-NS2)(PR-NS3)     •select and integrate information from various sources to observe the principal features of a mammalian circulatory system and the direction of blood flow, and identify structures from drawings; e.g., valves, chambers (PR-NS1)     •research and design a simulation or model of the functioning of the main components of the human immune system (PR-NS1)(PR-ST2)[ICT C6-4.4]     •compile and display information on blood pressure, heart rate and blood composition (PR-NS1)(PR-NS4)     •carry out a heart dissection to identify the major parts and to determine the directional flow of blood through the organ (PR-NS3))
