Below are some examples of investigations that were presented at UA Science Expo 2015.
The projects shown here are strong in some of the sections and need work in other sections.
** Exemplary UA projects should include sections as described below.
Download UA’s Long-Term Science Investigation Rubric to evaluate a project for yourself!Sections of the Long-Term Science Investigation:
Discussion/Conclusion: makes a claim (i.e., the hypothesis is or is not supported…), supports the claim with evidence, and uses reasoning—in the form of connections to scientific concepts—to relate claim and evidence. It is important that the Discussion/Conclusion refer to relevant scientific concepts (content knowledge) to explain why the claim and evidence are related. Scientific sources supporting results should be referred to and cited in the discussion. Reflections and “Next Steps” are included in the Discussion/Conclusion.Sample Investigations: Click the links below to view zoomable images of exit projects completed by Urban Advantage students during the 2014-15 school year.

Title of Project: The effect of time of the day on the vocalization frequency of great horned owls.
Question: How does the time of the day affect the vocalization frequency of the great horned owls?
Hypothesis: If the time of the day is night then the vocalization frequency will increase because they are more active at night.View the completed rubric for detailed information (PDF)
Question: What is the effect of the distance from trails on presence of Japanese Knotweed?
Hypothesis: If the amount of knotweed that is present in terms of distance from the trails is measured, then one would find that there are more knotweed plants closer to trails than there are further into the woods because according to specialists such as Maria Hernandez, knotweed seeds travel on birds, people, dogs, cars, and other modes of transportation and animals. When people or animals go to places infested with knotweed (such as Staten Island, as Clay Wollney reports), the seeds cling to their bodies, car tires, clothes, feather or fur, etc. When people and pets come by Central Park, they generally keep to the trails and if they carry knotweed seeds, the seeds fall of their host and land on the soil nearby the trails they travelled. The seeds then thrive in this soil and grow, making more seeds to be spread by more hosts.View the completed rubric for detailed information (PDF)
Question: How will scheduled feeding time affect the frequency of innate versus learned behavior in male California Sea Lions?
Hypothesis: The scheduled feeding time will increase the frequency of learned versus innate behaviors in the male California Sea Lion because marine mammals have excellent short term memory. (Herman, 2002).View the completed rubric for detailed information (PDF)
Question: How does the time of the day affect habitat usage in tufted puffins?
Hypothesis: Tufted Puffins will spend an increased amount of time on land compared to the water because From approximately September to March each year they swim catching fish wherever they go. They are rarely within sight of land for the entire winter (Maclead, 1990).View the completed rubric for detailed information (PDF)
Question: How will a Gentoo penguin activity level increase after feeding time?
Hypothesis: If I observe a Gentoo penguin two different times, one before feeding time and after feeding time than the Gentoo penguins activity levels will increase after feeding time because the Gentoo penguin diet of capelin converts into energy, therefore making the Gentoo penguin have an increase of activity. The Central Park Zoo feeds the penguins of the Polar Circle around the times of 10:30 am to 12:00 pm meaning that the activity levels will increase at around those times because the Gentoos have been fed.View the completed rubric for detailed information (PDF)
Question: What is the effect of fish body shape on rate of movement?
Hypothesis: If I observe fish with a fusiform body shape and compressed body shape, then the fish with the compressed shape will move the quickest because fish with a compressed body shape are flattened from side to side, which allows them to turn with ease and move quickly.View the completed rubric for detailed information (PDF)
Question: How does the different type of pinnipeds affect their surfacing frequency?
Hypothesis: If the harbor seal is measured for its surfacing frequency, then it will rank at first for the shortest surfacing frequency and the sea lion will rank at first for the longest surgacing frequency because according to Wikipedia, Harbor seals swim up to 12 minutes underwater, and sea lions swim up to less than 3 minutes underwater, causing a greater surfacing frequency.View the completed rubric for detailed information (PDF)
Question: What is the effect of types of spices on RAW non organic chicken breasts?
Hypothesis: I think garlic will have the most effect because when we researched spices, I found out garlic keeps away the most bacteria because according to www.dailymail.co.uk/, it says that Garlic is the only antibiotic that can actually kill infecting bacteria and, at the same time, protect the body from the poisons that are causing infection. In studies, garlic has been found to be almost as effective as penicillin also, there is a substance in garlic called allicin that is known to kill bacteria.View the completed rubric for detailed information (PDF)
Question: How will the sizes of the balloon effect the balloon car distance?
Hypothesis: If the size of the balloon effects the distance the balloon powered car travels then the car powered by the bigger balloon will travel further than the car powered by the smaller balloons. This is because according to the article ‘Balloon Powered Car’, Newton’s Third Law of Motion stated that for every action, there is an equal and opposite reaction. This means that the amount of air in the balloon will exert the same amount of force on the car. Also, according to the article Newton’s Law Of Motion , Newton’s Second Law of Motion states that a greater force create a greater acceleration in an object with the same mass. This suggests that the more air in the balloon, the faster the car will travel reaction is the air being released out of the balloon and the reaction will be pushing the air. So, the more air the more reaction it will have.View the completed rubric for detailed information (PDF)
Question: What is the effect of different wavelengths of light on the time taken for radish seeds to germinate?
Hypothesis: If blue light is used to grow the radish seeds then it would allow the seeds to germinate the quickest because all plants, which absorb chlorophyll, absorb blue light the strongest.View the completed rubric for detailed information (PDF)
Question: How does the places’ longitude affect a place’s temperature?
Hypothesis: If the longitude of Myrtle Beach and Miami is closer to 0oN, then the temperature will rise because of solar radiation. If a city is closer to the equator, then it will receive more direct sunlight and that will heat up the locations’ climate. This is because the land and water will absorb the head and will reradiate it back into the Earth’s atmosphere. This will affect the city’s temperature which then leads to the city because warmer. This all is affected by solar angle and solar radiation.View the completed rubric for detailed information (PDF)
Question: How will zebra mussels affect phytoplankton?
Hypothesis: If the population of zebra mussels increases, then the population of phytoplankton will increase because zebra mussels affect the turbidity since they are filter feeders, so the more zebra mussels, the clearer the water will be and the more sunlight phytoplankton will get. Also, zebra mussels eat small zooplankton which will eat phytoplankton so the population of phytoplankton will increase as more and more zooplankton get eaten by zebra mussels.View the completed rubric for detailed information (PDF)
Question: How does size of a rubberband affect the speed of the submersible?
Hypothesis: If we change the thickness of the rubber band (one sixteenth, three thirtysecondsâ€, one eighth)then the thickest rubber band (1/8â€) will increase the speed of the submarine because it stores more potential energy to transfer to the propeller (Pitsco, 2013). The more potential energy imposed on the propeller from the thickest rubber band, the higher the kinetic energy produced by the propeller thus increasing the speed of the submersible boat (Robertson, 2002).View the completed rubric for detailed information (PDF)
Question: How does the angle of the motor, the shape of the blades, the angle of the blades and the number of the blades affect the voltage that a wind turbine produces?
Hypothesis: If the number of the blades on a wind turbine is 8, the wind turbine will generate the most amount of electricity because there are more blades to catch wind and less air is lost between the blades.View the completed rubric for detailed information (PDF)
