Transcript: Undara by Ethan Daley information on place. Undara lava tubes Location: Mount Surprise information of Undara. what is a geologist? A Geologist is a person who does research on rocks, how they are formed, and how they became the way they are now. what is a geologist? What dream time or myths are there? There are no stories on Undara, but stone artefacts and scarred trees were found at Undara and Etheridge Shire. Undara is also an aboriginal word that means long way dream time stories or myths What rocks are at Undara? There are metamorphic and igneous rocks at Undara. Specifically Basalt and Corundum which is a type of sapphire. rocks at Undara extra information The total size of the Undara lava tubes is 615km squared. Semi-evergreen vine thicket grows in the moist, sheltered entrances to some of the lava caves. The roofs of some tubes collapsed, creating ideal conditions for dry rainforest to grow and wildlife to shelter. Rock-wallabies, insectivorous bats and owls roost here in the cool. Birds shelter in the fruit-filled canopy and predators lurk in the tumbled basalt terrain to complete the food chain. extra information on Undara How old is Undara? Undara is around 190,000 years old. Below is a timescale of Undara. age of Undara conclusion My conclusion is that Undara is a cave covered with igneous and metamorphic rocks, which was created by a shield volcano that is no longer active. The Undara Lava Tubes were formed when 23km cubed of lava from one of the many volcanoes spilled out over the land and traveled along a riverbed. The tubes were formed when the outer layer formed a crust which protected the still-molten lava and continued to flow as though it was in a tube or a pipe. It is believed that the entire length of 160km is the longest lava flow from any single volcano on earth. It is estimated that the whole process took between 2-3 weeks with the lava flowing at a rate of around 500m/h. The process that occurred was cooling, and the processes that are probably happening now is weathering and erosion. conclusion

Transcript: Section 3: Motion and force Accident investigators must apply physics formulas to find out the speed and velocity of vehicles involved in an accident. when an object changes position with respect to a frame of reference,the object is in motion Calculating Acceleration Cars could not move without friction Acceleration and Motion Combined velocities determine the resultant velocity v= d/t the force of friction always opposes motion Why is friction sometimes necessary Unbalanced force do not cancel completely The force of friction Acceleration can be seen on a distance vs time graph Friction and Motion friction is necessary for many everyday tasks to work correctly Chapter: 11 Motion Constant: a quantity whose value does not change Frame of Reference- a system for specifying the precise location of objects in space Force: an action exerted on a body in order to change the body's state of rest or motion; force has magnitude and direction Helpful friction can be increased 3. Motion and Force you can plot a graph showing distance on the vertical axis. Graphing Accelerated Motion instantaneous speed is the speed at a given time kinetic friction: the force that opposes the movement of two surfaces that are in contact and are moving over each other What force always opposes motion Friction and motion Speed and velocity speed: the distance traveled divided by time interval during which motion occured. a= whenever there is a net force acting on an object, the object accelerates in the direction of the net force Velocity is described relative to reference point Acceleration can also be a change in direction Accident investigators inspect car accidents or similar events to see who is at fault and determine how much the insurance company should pay. These forces are the force of gravity, the electromagnetic force, the strong nuclear force, and the weak nuclear force Balanced and unbalanced forces Why It Matters Uniform circular motion has centripetal acceleration Balanced forces do not change motion Chapter Outline v/t What do you need to know to find the speed of an object Fundamental forces Calculating speed How can you study speed by using graphs Key ideas What happens when there is a net force acting on an object Fundamental forces vary in strength How do you calculate the acceleration of an object moving in a straight line Static friction: the force that resists the initiation of sliding motion between two surfaces that are in contact and at rest Graphing Motion What changes when an object accelerates Accident investigators can expect to make between $40,000 and $60,000 a year. speed tells us how fast an object moves, and velocity tells us both the speed and direction the object moves Motion can be studied using a distance v. time graph 1. Measuring Motion Acceleration is the rate at which velocity changes Static friction is greater than kinetic friction Why it Matters Graphing Accelerated Motion 4/16/12 The Force of friction Displacement is the change of an object's position Evidence collected from the scene of an accident can be used to learn about the accident. Accident investigators apply physics formulas to find important information, such as the speed of a vehicle at the time the bakes were applied. A good accident investigator combines information from many sources, including skid marks, vehicle damage and witness statements. The investigator must come up with a theory that matches all evidence. Balanced and unbalanced forces How is a frame of reference used to describe motion Acceleration is negative when slowing down. The slope of a distance vs. time graph equals speed To detect motion you must observe the object relative to it's reference points. When you do you can measure distance the object traveled, displacement, speed, and velocity of the object. Acceleration is a change in speed or direction. To calculate acceleration you need the final velocity minus the initial velocity divided by time. A way to graph acceleration is a speed vs. time graph the slope is acceleration. . When forces are applied and produce a net force of zero they are balanced if the net force is above zero they are unbalanced. The force of friction opposes the motion between two surfaces that are in contact. Friction can be increased or lowered by making surfaces rougher or slick. the average acceleration over a given time interval can be calculated by dividing the change in the object's velocity by time over which change occurs Accident Investigator Friction: the force that opposes motion between two surfaces that are in contact Chapter Summary Acceleration and Motion Calculating Speed Acceleration: the rate at which velocity changes over time; an object accelerates if its speed, direction, or both change over time How can a graph be used to find acceleration Acceleration can be a change in speed Speed and Velocity Graphing Motion Observing Motion what do scientist identify as the fundamental forces of nature Unwanted friction can

Transcript: My hypothesis If you drink water then your heart rate will be closer to normal Background Research In the research conducted for this experiment Gatorade seemed to be the better drink to consume before an activity. Gatorade keeps you hydrated longer then water in intense workouts and activities. Gatorade was created as an athletic drink. It was an invention that was created in a lab in 1965 within the University of Florida. Some of the ingredients in Gatorade are potassium and sodium. Potassium acts as an electrolyte. Too much potassium however can lead to a disease called Hyperkalemia or excess amount of potassium in the blood stream. Sodium helps muscles contract properly and leads to a healthy blood pressure. However most foods are already high in sodium so if you do not exercise then you are at risk of health conditions like elevated blood pressure, stroke, and heart disease increase. Materials Materials- 2 clean cups per participant pre-measured/marked containers to hold 250mL of liquid metric measuring cup bottled water (same brand) (2250mL total needed, divided) Lemon-Lime Perform 02 Gatorade (same flavor/type) (2250mL total needed, divided) open space for activity space/chair for rest area willing participants for experiment Procedure Gather people and materials Prepare the water and Lemon-Lime Gatorade in cups (250 ml) Have participant rest for 15 minutes in a chair Have participant take pulse rate from the neck for 15 seconds Have participant jog in place for 2 minutes without any liquid Have participant take pulse rate for 15 seconds Rest for another 15 minutes in a chair Have participant drink water (250ml) Rest in chair for another 15 minutes Jog in place for 2 minutes Take pulse for 15 seconds Rest for 15 minutes Have participant drink Lemon-Lime Gatorade (250 ml) Rest for 15 minutes Jog in place for 2 minutes Take pulse for 15 seconds Repeat steps 1-16 for each participant two more times on two different days for a total of three trials per participant Record all data Data Table The data from this experiment helps us better understand the topic of weather water is better to drink rather than Gatorade before an activity. In the research conducted Gatorade seemed to be the better option for the activity. But the results show that water was better for the activity. The hypothesis of the experiment was that water was better than Gatorade for keeping your pulse rate down. According to this data in this experiment you should drink water rather than Gatorade. The impact of these results supports water in the fact that good for keeping your pulse rate down. It does not support Gatorade in keeping your pulse rate down. It could affect the marketing of both. In a positive way for water and negative for Gatorade. People might start to use water more than Gatorade which is healthier. The area of interaction for this experiment is Health and Social education. The reason for this Area of Interaction is that it is trying to figure out which drink is healthier for you so you can do physical activities with friends longer. If somebody was to do the exact same experiment then they might get completely different results or about the same data. The reason I say that is because if you get people that are used to drinking Gatorade before activities their body is used to it therefore their pulse rate may be lower than in my experiment. The reason being that the people I tested used both Gatorade and water regularly but water a little bit more frequently. This might have been a factor in my experiment as to why when the participants used water their pulse rate was always lower then when they used Gatorade. Which will you choose? I would like to thank a few people personally for their time. One is the Kidd family for letting me test them in the experiment. As well as my mother who let me use her computer when the one in our house crashed. finally I would like to thank my sister for letting me test her with this experiment. And my dad for letting me take over the computer when he had school work to do. Sources "the sports-drink wars" Time magazine blood: look at your body Gatorade Water gatorade Which will you side with My research question: will water or Gatorade be better for keeping your heart rate down?
