Wayfinders are We! (Part II)
In this second part of the project, students do floatation tests on their model wa'a and use a water-filled trough to observe and measure the speed of the canoe in various conditions. Times are recorded for currents created with one pump, two pumps, three pumps ... all the way up to the strongest trough current created with 6 pumps.
As a result of this lab, students will know and understand these things: (1) Measurable attributes of objects and the units, systems, and processes of measurement; (2) The application of appropriate techniques and tools to determine measurements; (3) Collecting, organizing, and displaying data; (4) Selecting and using appropriate methods to analyze data; (5) How to solve simple problems involving scale factors, using ratio and proportion; (6) Unit rate calculations; (7) The use of conversion factors to convert measures; (8) The use of conversion factors in simple dimensional analysis to convert between different measurement systems; (9) Circumference of a circle; (10) Volume of a rectangular prism; and (11) Calculations of speed.
