Senior Physics - Extended Experimental Investigations. Roof colours - white vs. Nobel laureate Steven Chu, former. University of California and now.
U. S. Energy. Secretary in President Obama's administration says "white. However, Steven Chu said, even if. Making roads and roofs a paler color could have the equivalent. That sounds. like an ideal EEI. One Australian company sells just the thing: White. Roof Shield is a white coating which reflects 8. They say it "helps reduce interior cooling loads of air conditioned structures. Even buildings without air. Put some roofs of different amounts of whiteness in the sun for some. Maybe a heating curve is best. May need more than three trials, and what's the. What about flat paint vs satin vs glossy? Home. Insulation - is thicker better? Ceiling insulation is one way of. Insulation materials such as. In 2. 01. 0 the Australian Government. Many were installed improperly and in some case fires and death. ![]() The research question that could be useful for a Senior Physics EEI is. There is a. great temptation to compare the various materials to see which performs best. Such a comparison may. Junior Science project or EEI but it is very problematical for a. Senior Physics EEI. Presumably you would have different building materials to. If it is just "type. Download the free trial version below to get started.Double-click the downloaded file to install the software. Samsung Galaxy Grand Neo Software Free Download . You could have variable. R- values but you would need to keep all other variables constant (thickness. My suggestion is to investigate varying thickness of a single insulating. That way there would be some physical quantity to analyse other than. R- value (which is merely the result of an experimental determination anyway). The last thing you want is the temperature inside the house for a bunch. That is, what is their relationship to each. This is a physics EEI and physics principles, theories and concepts must. Otherwise, I think you would find difficulty in being able to. Queensland Syllabus IP3): "identify relationships between patterns, trends, errors and anomalies" when. This. also applies to criterion EC1: "analysis and evaluation of complex scientific. Proshow Producer 4 Keygen Download For Vegas . Varying the thickness avoids this.Here's a suggestion: use a light- box kit to provide the. I put the insulating material (yellow cardboard) on top. Worked like a charm - and. As a bonus, you could even look at a second variable - that of. V, 1. 0V, 8. V..). My graph showed that the single layer of card (top line). Hmmm - how to. explain that? This is a rich source of data. What would three pieces of. I also tried six layers of paper towel but the. Why was. that? I think hot air made its way through the paper. But 6mm expanded. What a great source. Do it well and I'd have to get an A+. Some teachers have used this idea in the context of "sustainability". Students investigated the effect of thickness of more natural construction. Art. Department). In this cases you would be looking at wall insulation, not. Tennis. Racquet - Sweet and other spots. On the face of the tennis racquet, there are. A couple of the spots are shown on the diagram below. The. centre of percussion is one of the two "sweet spots" of the racquet. This is. because at the point of impact between the centre of percussion and the ball. This is due to the fact that the centre of. You can. easily find out what all this means and about the other sweet spot. A good EEI. would be to test the 'coefficient of restitution' (ratio of bounce height to. Perhaps clamp the racquet in a vice. Does drop height affect the coefficient of. Is the type of ball important? Does a temperature change shift the. Are new racquets better than old? Is aluminium better than. Does string tension play any part? The possibilities are endless. The. photos of professional players show that the serving spot is high and the return. Note: Brad Barker from Carmel College has listed "Physics of Sport. EEIs" that have worked at his school. Click hereto download. Perfect serving spot.The various 'centres' on a tennis racquet.Experimental setup at Moreton Bay College for Year 1.Physics EEI - 2. 01.Danger inside a hot car.After rescuing 2. I Spy Treasure Hunt Cheats . Royal Automobile Club of Queensland has. The RACQ says that on. Australian summer day, the temperature inside a parked car can be 3. C hotter than outside the car. That means that on a 3. C day, the. temperature inside the car could be as high as 7. C and 7. 5% of the temperature. They also say that. I would have though much higher temperatures); and. The key variables are. EEI and having a data logger would be great. But some others. worth considering are the colour of interior trim; having the windows down a. You could even model a car by using painted. Blu- tac. Maybe you. Oh, the possibilities are endless but and it looks easy but controlling the variables will be. Descent of golf balls down an incline If. You could measure time vs. Is acceleration uniform? Why do similar looking balls give different results. Maybe it is to do with their dimples or hardness (Novice = long. Intermediate = very long & soft; Power = straight & very soft; Titleist = extremely long, and so on). Try removal of dimples! Use a light gate at bottom to. That's. Melody's hands in the photo below. She's from Moreton Bay College. Cars on a ramp - angle and. If you ride a. skateboard down a hill you know that your speed increases as you go down. This. happens for all sorts of things: riding a toboggan down a sandhill, skiing. Even cars get faster if they accidentally roll. You can reach dangerous speeds if you have no way of braking or. With cars and trucks it may be impossible to stop them and the. An EEI could look at factors that. Knowledge of. these factors may help in the design of sports grounds skateboard bowls, ski. It could even help road engineers ensure that. What could make a good EEI. This does make an excellent Year 1. EEI but it also is very suitable. Year 1. 1, particularly if you choose to look at a second variable (mass). We all know that GPE is converted into KE but is it. By timing the car over the metre you can work out the. Varying the angle will give. Don't forget to include 0. You would think you'd get a y ∝. Plenty to talk about. For 6 cm, 9 cm. and 1. I got final speeds of 7. Efficiency of energy transfer was 4. Hmmm! Cars on a ramp - stopping distance of toy cars along the floor due to friction. For sliding friction on an incline, the coefficient of friction μ =. You could let. a car roll down a ramp on to the horizontal floor and see how long a distance it. How does this vary with the height (which determines the starting. It maybe tempting to use a solid ramp but the. To get a. smooth run a curved surface could work. I just used some carpet tiles with the. The question is: where is the friction in a toy car travelling. You could also look at the effect of the mass of the car and so on. What are the. practical implication for this? Does twice the mass (eg a truck compared to a. It is tempting to compare the rough. Maybe you could. measure the coefficient of friction of the material first and use that as the. This is certainly not as simple as it looks and may, at first glance. Year 1. 0 EEI but there is a lot in it and could be good at a. Year 1. 1 level. The distance d (or displacement s) is easy to measure but. GPE = mgh formula? I've shown it here as the vertical distance between. But could that. be improved? Can you assume the conversion to KE is 1. Would you need to measure. Is all of the GPE converted to work done in bringing the car to a. GPE = mgh = W = Fs = mas)? Whew, so much to think about. On this rough side of the carpet tile and a starting. Blu- tacked to its hood. Still with a starting height of 1. Is. distance proportional to mass? Using a Smartphone Accelerometer on an inclined plane. The Queensland Studies Authority has an "A" standard sample EEI on their webpage that describes the use of a smartphone in measuring acceleration down an incline. It may provide some good ideas about what you can do - and gives you an indication of what an "A" response could look like. Click here to download. D accelerometer apps are available free for all phones (Moreton Bay College)Rolling friction of a ball. When a ball rolls along a surface it will eventually come to rest. Because it gradually slows down we say there must be a force opposing its. We can think of friction being. In class, you. will have most likely dealt with static and sliding friction because they is easy. In. contrast, rolling friction is harder to measure as it is usually much smaller. If a cylinder or ball is freely rolled along a horizontal surface, it will.
