Research-Based Essay Project Topics:
Below you will find several descriptions of possible topics for the research essay. Students are free to choose any topic from this list or may choose their own project. Feel free to discuss your ideas with Mr. Jennings prior to commencement of your this type of project.
The Hubble Space Telescope
Investigate the research being done with the Hubble Space Telescope (HST). Your investigation should include (a) a description of its components and how it works (i.e. the optics of its telescope and cameras), (b) the findings from various studies that use the telescope and (c) the future of space telescopes, namely the James Webb Space Telescope, and how they will improve on HST.
Investigate Einstein’s theories of special and general relativity. In particular, research (a) how these theories are vital in the correct functioning of the Global Positioning System (GPS) and (b) the possibility of using wormholes to achieve ‘faster-than-light’ travel.
The Higgs Boson
Research the recently-confirmed discovery of the Higgs Boson and its implications for the Standard Particle Model. How does its discovery change this model? Does it lead scientists to a greater understanding of the Grand Unification Theory? What does this particle have to do with why objects have mass? Why or why not? This essay should contain an explanation of the Standard Particle Model and how the Higgs Boson adds to it.
What do we learn from spectroscopy in astronomy? Discuss the history of astronomical spectroscopy and of its applications. You should include a discussion of spectroscopy at other wavelengths besides the optical window.
Suggested References (non-exhaustive):
Study and report on the theory of echolocation in dolphins. Do other animals use a similar method? Predict a possible evolutionary path of the human species in which echolocation is employed. How would humans utilize this characteristic?
In June 1990 Stephen Hawking conceded a bet (made in 1974) with Kip Thorne. He agreed that the Cygnus X-1 system contained a black hole. For over 200 years since John Michell described "dark stars" (stars massive enough to stop even light escaping from their surfaces), black holes had been an astronomical enigma. They now are accepted components of our Universe. This project requires a qualitative description of black hole properties and their increased importance in 20th century astrophysics, as well as noting methods in determining their inferred properties from indirect observations.
Outline the characteristics of the Big Bang theory of the formation of the Universe. How is it different that the Steady State theory? What observational evidence leads astronomers to believe that the Big Bang theory is the most appropriate theory? What are some possible fates of the Universe? The 'geometry' or 'shape' of the Universe should be discussed in your essay.
Research the historical development of the concept of gravitational force. Find out how scientists’ ideas about gravity have changed over time. Identify the contributions of different scientists, such as Galileo, Kepler, Newton and Einstein. How did each scientist’s work build on the work of earlier scientists? Analyze, review, and critique the different scientific explanations of gravity. Focus on each scientist’s hypotheses and theories. What are their strengths? What are their weaknesses? What do scientists think about gravity now? Use scientific evidence and other information to support your answers.
Choose Your Own Topic
If there is a topic in physics that is not on this list, but you would like to research, consult Mr. Jennings in order to develop a good project description (i.e. thesis) and a list of appropriate references and a list of appropriate references.
Exploratory-Based Project Topics:
Below you will find several descriptions of possible exploratory-based projects. These were adapted from Science Buddies . Students are free to choose any project from this site provided that it is a) physics-related & b) at an "intermediate" or "advanced" level. Feel free to discuss your ideas with Mr. Jennings prior to commencement of your this type of project.
Catapult Read "The Art of the Catapult" by William Gurstelle PDF
Research various designs for catapults (see Mr. Jennings for a good book on catapults). Choose one design and build a functioning replica. Use your catapult to test for the optimal angle for launching projectiles. Submit a research project that outlines the theory and historical research into projectile motion, your observations and analysis and concluding remarks.
The Science of Spin: A Baseball Pendulum
For this project, you'll use a baseball as a pendulum weight, studying the motion of the ball with and without spin. Wrap a rubber band around the ball, and tie a string to the rubber band. Fasten the string so that the ball hangs down and can swing freely. Mark a regular grid on cardboard, and place it directly beneath the ball to measure the motion. You can also time the oscillations with a stopwatch. Lift the ball along one of the grid axes, and let it go. Observe the motion and record your results. Next, twist the string 50–100 times, and again lift the ball along one of the grid lines and let it go. How does spinning change the motion of the pendulum? Try changing the orientation of the seams of the ball: is the pendulum motion affected? What happens if you wind the string in the opposite direction? Can your results help you explain how a pitcher throws a curve ball?

On the Rebound: The Height Limits and Linearity of Bouncy Balls
You might think that plants and animals have little in common with batteries, springs, or slingshots, but they actually do have something in common. Both living and non-living things store and transfer energy, from one form to another. In this project, you'll investigate this energy storage and transfer, not in a plant or animal, but in bouncy balls. You'll find out if there are limits on how much energy can be stored and if there are losses when the energy is transferred. The objective is to determine the rebound height limits and evaluate the relationship between the dropped height and the rebound height of dropped bouncy balls.

Roller Coaster Marbles: Converting Potential Energy to Kinetic Energy
If you'd like to investigate the physics of amusement park rides, then this project is for you. You'll build a roller coaster track for marbles using foam pipe insulation and masking tape, and see how much the marble's potential energy at the beginning of the track is converted to kinetic energy at various points along the track. The goal of this project is to build a roller coaster for marbles using foam pipe insulation and to investigate how much of the gravitational potential energy of a marble at the starting point is converted to the kinetic energy of the marble at various points along the track.

Distance and Speed of Rolling Objects Measured from Video Recordings
This project is an experiment in classical physics. You'll be following in Galileo's footsteps, and investigating Newton's laws of motion, but you'll be taking advantage of modern video recording technology to make your measurements. Sure, it's been done before, but if you do it yourself, you can get a firm understanding of these important concepts. The objective of this project is to determine the relation between elapsed time and distance traveled when a moving object is under constant acceleration.

Don't You Fret! Standing Waves on a Guitar
In this project, you'll investigate the physics of standing waves on guitar strings. You'll learn about the different modes (i.e., patterns) of vibration that can be produced on a string, and you'll figure out how to produce the various modes by lightly touching the string at just the right place while you pick the string. This technique is called playing harmonics on the string. By the way, we chose a guitar for this project, but you can do the experiments using any stringed instrument, with or without frets. The goal of this project is to investigate which standing wave patterns you can produce on a guitar string by playing harmonics.

Building a Cell Phone Microscope
Imagine you are on a trip and see something interesting that you want to share with your friends. What do you do? You take a picture with your cell phone and e-mail it to them, of course. But did you realize that the same technology can be used to save lives? Using their cell phones modified as inexpensive microscopes, medical personnel can look at blood smears to help diagnose diseases like malaria and cholera. In this photography science project you will build a simple and inexpensive cell phone microscope and use it in your choice of imaging applications. The objective of this project is to build a cell phone microscope and use it in an imaging application.

Have you ever played paintball with your friends? Wonder how you can improve your game? Paintball guns use compressed gas to shoot paint-filled pellets at high speed, and with good accuracy. The flight path of the ball is determined by its speed and the angle at which it is shot, relative to the ground. In this sports science fair project, you will explore the ballistics of paintballs, focusing on how drag and other factors affect the results. The objective of this sports science fair project is to compare the calculated vs. actual range and launch velocity of a paintball. The difference between the expected values, based on calculations, and the actual values, which are measured experimentally, is caused by drag and other real-world factors.

Acceleration Due To Gravity
Conduct three distinct methods to measure the acceleration due to gravity, 9.81 m/s2. The methods should involve the following scenarios: free fall of an object, motion of a simple pendulum and the motion of a spring. Each method should compare the accuracy of the results to the known value and advantages and disadvantages of each method. Submit a full laboratory report, compiling the results from the three methods.
Golf Clubs, Loft Angle, and Distance
If your idea of a great weekend morning is taking some practice swings at a driving range, or heading out to the links to play a round, this could be a good project for you. This project is designed to answer the question, what is the relationship between club loft angle and the distance that the ball travels when struck. The goal of this project is to measure how the initial launch angle of a golf ball affects how far the ball travels.

A Cure for Hooks and Slices? Asymmetric Dimple Patterns and Golf Ball Flight
Have you ever wondered why golf balls have a pattern of dimples on their surface? The dimples are important for determining how air flows around the ball when it is in flight. The dimple pattern, combined with the spin imparted to the ball when hit by the club, greatly influence the ball's flight path. For example, backspin generates lift, prolonging flight. When the ball is not hit squarely with the club, varying degrees of sidespin are imparted to the ball. A clockwise sidespin (viewed from the top) will cause the ball to veer right (or slice). A counterclockwise sidespin will cause the ball to veer left (or hook). This project attempts to answer the question, "Can an asymmetric dimple pattern decrease hooks and slices?" The goal of this project is to test whether an asymmetric dimple pattern on golf balls can produce straighter flight.
