biological conditions of a particular stream site. It is great for assessing land use practices and determining whether a stream is fit for a certain species to thrive. 6.) The major weakness with QHEI is that it is very open to interpretation. The measurements that make up the QHEI assessment are determined by the observer. There is no real scientific method to get an exact number on many of the characteristics such as how

add the acid into it we would be able to tell when the end point comes because the colour will change. Qualitative and quantitative comparison: I think that quantitative technique is more important than qualitative for titration because if the measurements for titration and standard solution are not accurate and precise then then it can affect all of our result and conclusion can be completely different than the one expected. Qualitative on the other hand also plays important role but not as much

Introduction My aim was to study the changes of the river Chess from source to confluence. The hypothesis: There is a correlation between river discharge and erosion. My key questions: Will the wetted perimeter increase further downstream ? Will the river channel get wider further downstream ? Will the river channel get deeper further downstream ? Will the velocity increase further downstream ? Will the pebble size change further downstream? The key terms I will use are: Discharge –

An outcomes-based approach to education clearly specifies what students are expected to learn and arranges the curriculum such that these intended outcomes are achieved (Harden, 2007). Learning outcomes provide the base for an effectively aligned and integrated curriculum, where instructional activities and assessment strategies are explicitly linked to course-specific and degree-level learning outcomes, which are tied to institutional and provincially-defined graduate degree level expectations (DLEs)

PH: PH is the level of acidity or basicity in a body of water. Anything less than 7 is considered acidic anything above 7 is basic. Around neutral or 7 is a healthy reading for PH but slightly higher or lower than that is fine too. To test for turbidity you put some water in a PH meter or in a solution to find out for the reading. In Milton we had a reading of 7.6 for the meter and a 7.1 for the solution. In mcnulty we had 6.7 with the meter and 7.1 with the solution these are all good readings for

stations on sea bottom or below surface and/or ice. The navigation system is based on a strap-down inertial measurement unit (SD-IMU) mounted on an underwater vehicle and assisted with auxiliary navigation sensors, such as Doppler velocity log (DVL), depth, and heading sensors. Range measurement transducers are additional auxiliary navigation sensors. Using the two range measurements, the proposed navigation system will be able to improve the performance of conventional IMU-DVL navigation

Adrian Garza 1/17/15 2nd Period Bubble Lab Experiment 1. What do I want to find out? What I want to find out is if the type of soap will affect the size of the bubble. For this we will test 3 different types of soap brands. 2. What do you think will happen? What I think that what will happen is that the orange soap will produce bigger bubbles than the other 2 soaps. 3. Materials: Straw, Pipette, ruler, beaker 4. Procedure: Mix water and soap together in a beaker Draw solution

Automatic zero calibration – for added accuracy This is a function that gives an indicative reading within 14 Seconds for poor thermal conductivity items. The use of this Function will reduce the accuracy to +/-2°C. For correct Speed-read measurements the probe must be in good Thermal contact with medium under test prior to activating the Function. A steep temperature gradient or wide temperature Difference between the initial probe temperature and item Under test is required. Speed-read

Measurement and Measurement Error PHYS 1313 S06 Prof. T.E. Coan Version: 16 Jan ’06 Introduction Physics makes both general and detailed statements about the physical universe and these statements are organized in such a way that they provide a model or a kind of coherent picture about how and why the universe works the way it does. These sets of statements are called “theories” and are much more than a simple list of “facts and figures” like you might find in an almanac
