Brooke's PHY112 Fall '11

PHYSICS CONCEPTS

Electrical and Magnetic Properties of Matter

Electricity simulations including electron hockey

Current through resistors, high resistance vs low resistance

coils of wire act as inductors, collecting charge and creating a magnetic field, which in turn can effectively transfer charge to nearby matter.

Electromagnetic Radiation, Accelerating charge, Electromagnetic spectrum: range of frequencies divided into groups of how they interact with matter, Radio waves, Infrared, Visible light, ultraviolet, x-rays, gamma rays, Electromagnetic waves and their propwrties, refraction, reflection, diffraction, transmission, Ray model of light, Specular Vs DIffuse Reflection, Image formation, virtual vs real, magnification eq, Snell's law, refraction of waves between different mediums, experimented with acrylic to find the critical angle, which is the point of total internal reflection, Convex vs concave reflection/refraction, Young's equation: Path difference of 2 pt source interference

Fields & Forces

Bowling ball/ golf ball blanket distortion

Magnetic field and it's effect on copper wire with a flowing current. North/south pole of looped wire.

DC & AC Circuits

Felt the power of a charged circuit, by accidentally shocking myself by touching a lead on the circuit board for my coil gun.

Learned the difference between AC and DC by explaining the circuit board of the camera flash in my project 1 technical document.

Electromagnetism

Researched Faraday- Discovered his work led to the technology for motors.

Elements of Modern Physics

researched the capabilities of the Hubble space telescope and it's contribution to physics and astronomy

watched Paul's video about the inner workings of a cars alternator, its charging system

Began research on Nuclear Fission, which is the splitting of the nucleus of an atom, Found that Nuclear Reactors use neutrons to break apart uranium molecules, releasing heat in the process, which in turn is used to heat water to make steam then harnessed for generating electricity, Ernest Rutherford conducted the first experiments in Nuclear fission, and resulted in further experiments by Otto Hahn who with the help of Lise Meitner determined Uranium could be split into Krypton and Barium.

X-rays are a form of electromagnetic radiation that can penetrate most tissue/ articles that aren't extremely dense (can't penetrate metal or bone). Fall on the spectrum just below gamma rays. Some wavelengths overlap into the gamma spectrum.

CT Scans: Uses multiple x-ray images around an axis to get a sliced image of the item being examined. Computers render the images.

MRI: Uses Nuclear Magnetic Resonance to examine soft tissue of the body, works best with tissue that is not very dense and has a lot of water, ie muscle, connective tissue

PET Scan: Uses biological molecules with tracers that emit gamma rays injected in the body to visually examine functional systems within the body, ie glucose uptake

Lasers: So many uses! From pointers to checkout scanners, measures the bouncing back of the laser beam. Medical uses include using lasers to break up pigment in skin to eliminate tattoos, uses the precise cutting technology by heat to perform laser eye surgery.

Watched the elegant universe and learned about the development of string theory and why this search was so important.

TECHNICAL COMMUNICATIONS

Effectively communicate qualitative and quantitative information orally and in writing

Posted Neat Video to share with the class a cool physics related video on class Google Site

Made a neat video with a model of a "stripped down motor" experiment using a magnetic field and coiled copper wire with a current to make the coil spin.

created a neat video showing how a fluorescent tube can light using the electromagnetic field of high tension power lines

Made a sumarization of explanation for the topics assigned for weeks 12-14

Created a neat video about the appearance of colors in markers and how blotting paper and water can separate the colors we perceive.

Created a neat video using a rubber band to make vibrations and move nearby cheerios hanging on strings.

Explain the application of fundamental Physics principles to various physical phenomena

Taught my son how to ride a bike using newton's first law of motion

Made a neat video showing chromatography at work

Apply appropriate problem-solving techniques to practical and meaningful problems using graphical, mathematical, and written modeling tools

Ran Simulations on PhET for DC currents

Wrote a technical document describing the functions of a telescope, including ray diagrams

Using web2.0 and media apps, communicating all of what I've learned

Using mindmeister, dipity, and my google site to show what I have been working on

Created my portion for the coil gun project, taking on topics such as charge, current, voltage, magnetism, induction, resistance

SOCIETAL SKILLS

Work effectively in collaborative groups

Contacted Group about Project 1 organization and logistics

Worked with my group to create a video for project 2

Argue various sides of controversial topics using appropriate scientific argumentation techniques

Wrote on three different controversial debate topics, including astrology, global warming, and intelligent design, commented on other topics posted.

Educate yourself and your children

Showed my kids the electricity simulations and tried shocking each other
