A Photo Finish for the School Year

Posted: Friday, June 1st, 2012

by Laura Henriques and Katie Beck

CSTs and AP exams are over.  Students and teachers can all breathe a sigh of relief. With those pressures off, many teachers have a little more time for multi-day projects and experiments which all-too-often get squeezed out of the curriculum in our rush to make it to exam day. Many high school physics teachers have end-of-year projects which require students to be creative, have fun and apply concepts. Some of the more popular projects shared at a recent gathering of high school physics teachers included cardboard boat building, two liter bottle rockets, mousetrap cars, Rube Goldberg contraptions and catapults. There are variations to all of these activities but to be educationally valuable, students need to be able to explain the physics behind the project.

Surface Tension by Anna Christiansen Cable

The physics picture project described here is one that has been used in high school and university physics classes, but it could easily be used in other content areas. Adapted from the American Association of Physics Teachers Photo Contest, this project requires students to take a group of pictures to illustrate physics concepts. Virtually everyone has access to a digital camera these days (camera phones work fine for this assignment), so access to technology has not been a barrier, even in lower SES schools. Details on the project are provided below, but the goal of the assignment is to get students to photograph and explain how physics is seen in the natural (or posed!) world. Students need to explain the physics behind each picture and each of their pictures must demonstrate a different physical phenomenon. For example, they cannot provide pictures of a child on a slide and a child on a swing-set and explain both with conservation of energy principles.

Students have been excited about the project and the work they submit is really quite good. Pictures and their explanations must fit on a single page. Many of these are framed and posted in the classroom. Alumni love coming back and seeing their photos.  Current students are intrigued by the pictures and they read about the physics phenomena all year long. We have used this assignment as part of the final exam grade. It really is a culminating exercise, requiring students to retrieve and apply physics concepts from across the school year. It could easily be used throughout the school year as a portion of unit, quarter or semester grades. The goal is to require students to see and explain physics concepts at work in the real world. Group sizes can vary. We have had students work individually or in groups of 2-5. At the high school level groups have been used almost exclusively.

Assignment details: Take 10 (or some set number) of pictures which illustrate physics concepts. Your picture set must have a theme. For example, children at play (swing sets, slides, playing with slinkies) or a day at the beach (waves, rafts floating on the water, polarized sunglasses). Each picture must show a different physics concept and the physics concept highlighted in the photo must be explained in writing.

Variations on the assignment have included the teacher randomly selecting concepts or the instructor providing images which the students must describe. Our favorite version, though, is requiring teams to come up with a theme for their photo set and take their own pictures. It has been fun to see how clever and creative they are.

Purple Rain by Jason Daniel Connell, demonstrating vector motion.

We have found that doing a few sample pictures in class has been helpful. We show a picture and ask students to describe the physics behind it. Typically the class comes up with more than one physics concept that the image illustrates. For example, the kid on a swing-set mentioned above as an example of conservation of energy could also be an example of periodic motion. Instead of talking about the transfer of potential energy to kinetic energy the students could write about the period of the swing and the irrelevance of the mass of the child swinging as length is the only variable that matters. This is especially helpful for kids as they begin thinking about their project and helping them see that the pictures they take could be described using a different physics lens.

Try it out! You don’t have to start with a theme-based photo set of 10 images. Start out small with you providing a couple of pictures and see what they come up with. Then next year expand the project and have the students take the pictures. Another way to get started, and help the kids get comfortable with the idea, is to do photo analysis in class and include a picture or two on tests or quizzes which students must explain. This really helps students see physics as more than just a set of formulas.  Have fun and say cheese!

Some ways to celebrate the 100th anniversary of the National Park Service in your classroom

Posted: Thursday, September 22nd, 2016

by Carol Peterson

1) To celebrate the 100th anniversary of the National Park Service, Google has put together a collection of virtual tours combining 360-degree video, panoramic photos and expert narration. It’s called “The Hidden Worlds of the National Parks” and is accessible right from the browser. You can choose from one of five different locales, including the Kenai Fjords in Alaska and Bryce Canyon in Utah, and get a guided “tour” from a local park ranger. Each one has a few virtual vistas to explore, with documentary-style voiceovers and extra media hidden behind clickable thumbnails. Ideas are included for use in classrooms. https://www.engadget.com/2016/08/25/google-offers-360-degree-tours-of-us-national-parks/. Learn More…

The following individuals and organizations will be honored during the 2016 California Science Education Conference  on October 21- 23 in Palm Springs. This year’s group of awardees are truly outstanding. Please join us in congratulating them!

Margaret Nicholson Distinguished Service Award

John Keller

John Keller

The Margaret Nicholson Distinguished Service Award honors an individual who has made a significant contribution to science education in the state and who, through years of leadership and service, has truly made a positive impact on the quality of science teaching. This year’s recipient is John Keller, Ph.D. Dr. Keller is Associate Professor, Cal Poly San Luis Obispo and Co-Director, Center for Engineering, Science, and Mathematics Education, Cal Poly San Luis Obispo. In her letter of recommendation, SDSU science education faculty and former CSTA board member Donna Ross wrote: “He brings people together who share the desire to make a difference in the development and implementation of programs for science teaching. Examples of these projects include the Math and Science Teaching Initiative (MSTI), Noyce Scholars Program, Western Regional Noyce Initiative, and the Science Teacher and Researcher (STAR) program.” Through his work, he has had a dramatic impact on science teacher education, both preservice and in-service, in California, the region, and the country. He developed and implemented the STEM Teacher and Researcher Program which aims to produce excellent K-12 STEM teachers by providing aspiring teachers with opportunities to do authentic research while helping them translate their research experience into classroom practice. SFSU faculty member Larry Horvath said it best in his letter:“John Keller exemplifies the best aspects of a scientist, science educator, and mentor. His contributions to science education in the state of California are varied, significant, and I am sure will continue well into the future.” Learn More…

NGSS: Making Your Life Easier

Posted: Tuesday, September 20th, 2016

by Peter A’hearn

Wait… What?

NGSS is a big shift. Teachers need to learn new content, figure out how this whole engineering thing relates to science, and develop new unit and lesson plans. How could NGSS possibly make life easier?

The idea that NGSS could make our lives easier came to me during the California State NGSS Rollout #1 Classroom Example lesson on chromatography. I have since done this lesson with high school chemistry students and it made me think back to having my own students do chromatography. I spent lots of time preparing to make sure the experiment went well and achieved the “correct” result. I pre-prepared the solutions and organized and prepped the materials. I re-wrote and re-wrote again the procedure so there was no way a kid could get it wrong. I spent 20 minutes before the lab modeling all of the steps in class, so there was no way to do it wrong. Except that it turns out there were many. Learn More…

Celestial Highlights, September 2016

Posted: Tuesday, September 20th, 2016

by Robert C. Victor. Twilight sky maps by Robert D. Miller. Graph of evening planet setting times by Dr. Jeffrey L. Hunt 

Our evening twilight chart for September, depicting the sky about 40 minutes after sunset from SoCal, shows brilliant Venus remaining low, creeping from W to WSW and gaining a little altitude as the month progresses. Its close encounter within 2.5° N of Spica on Sept. 18 is best seen with binoculars to catch the star low in bright twilight. The brightest stars in the evening sky are golden Arcturus descending in the west, and blue-white Vega passing just north of overhead. Look for Altair and Deneb completing the Summer Triangle with Vega. The triangle of Mars-Saturn-Antares expands as Mars seems to hold nearly stationary in SSW as the month progresses, while Saturn and Antares slink off to the SW. Learn More…
