With funding from NSF’s DRK-12 program, the Center for Astrophysics | Harvard &amp; Smithsonian is researching and developing a next generation browser-based spectra visualization and analysis tool, The Spectrum Laboratory: Investigating the World of Color. Accompanying curriculum investigations enable students to use spectra from publicly available research databases -from atoms and molecules, to plants and pigments, to stars, galaxies and exoplanets - to support a wide range of authentic inquiry projects in the classroom. Spectroscopy is the universal analytical tool of science, yet it is typically touched on only briefly if at all in most people’s pre-college experience. Through this project we are testing the hypothesis that repeated opportunities to generate and analyze graphical spectrum plots and data, in association with real-world data and inquiry-based tasks, can help learners productively reorganize and prioritize existing ideas about light and color phenomena, and support them in productive participation in scientific practices.

technical paper

My students are used to learning physics through laboratory experiments, demonstrations, and projects. To simulate similar hands-on learning experience in a virtual classroom and make the subject more relevant, the students completed “Physics At Home Project”. They performed two physics experiments or demonstrations at home, took pictures of five things related to physics, explained how the pictures depicted physics concepts and principles, created video and QR code of their work, and presented the project via Teams, an online platform. The outcome were varieties of physics topics including, forces, Newton’s laws, heat transfer, specific heat, energy conservation, impulse-momentum theorem, and collision. During the presentation, the students were able to use physics vocabulary terms to discuss their project. They discovered relevance in some materials learned in physics by observing that everyday things in their environment are related to physics. Also, they learned how to present work in an online platform, and make YouTube video and QR code.

Sharing Physics Through Sound: Undergraduate Outreach

This summer, Wake Forest University's introductory calculus-based physics courses were delivered fully remotely for the first time. The laboratory portion of the course was primarily conducted using the iOLab Wireless Lab System. We moved to the system on relatively short notice. We conducted lab meetings through synchronous sessions on Zoom to introduce each lab. Following the sessions, students worked on the experiments independently or occasionally in pairs. I will report some of the successes and challenges we experienced.

Conducting a Summer Introductory Laboratory on Short Notice Using iOLab

The rapid shift to online instruction presented daunting problems, but also an interesting question: What do we REALLY want students to learn from an introductory physics lab? At Cuyamaca College, we decided that we cared that students (1) connected abstract course material to something concrete, (2) understood how to collect, analyze, and present data to test a scientific idea, and (3) could communicate their own scientific understanding. To do this we designed two simulation based labs and a project. The lab project, a multi-part assignment spread over the remainder of the semester, asked students to propose, design, run, and present a lab themselves using tools they had at home or could get safely and cheaply. By providing a few examples and a lot of support, we received some truly remarkable projects ranging from DC motors and electromagnets to pendulums and egg drops. Student feedback was overwhelmingly positive.

Home Lab Project: Cheap, Simple Labs Deliver Complex Lessons

A safe, nurturing learning environment, hands-on collaborative learning, interaction with women model scientists, laboratory and industrial plant tours, engagement using novel experiences, and an atmosphere of positive reinforcement were key interventions implemented in a physics camp designed to enhance the physics learning of and disciplinary appreciation by middle school girls. The Physics Wonder Girls Program provided a free, renewable energy physics-based summer camp to two cohorts of middle school girls from the Philadelphia area. Coming from diverse communities, the girls took a crash course on circuits using solar cell kits, and built and raced solar cars and boats. They compared the efficiencies of silicon cells vs. organic solar cells, built solar cells based on dyes from raspberry and blackberry fruit, and used a thermal imager to audit heat leaks. They met women physicists and engineers, toured a local food plant and presented demonstrations to a community of friends and teachers.

A Free Renewable Energy-based Physics Camp for Diverse Middle School Girls

Smartphones have the potential to revolutionize how students learn physics. This talk will introduce teachers to several hands-on activities designed to explore core disciplinary ideas in physics. The activities exploit the highly sensitive and precise sensors in the smartphones that students already own, and of which they are expert users. You will be amazed at the performance of the sensors and the diverse set of high-precision experiments that are now possible. These activities are designed to require minimal additional equipment beyond the smartphone, allowing them to be conducted in classrooms with limited resources and through distance learning programs to engage in sophisticated experimental activities at home. Several of the activities will be presented and resources to perform others will be provided. Examples include activities on motion, collisions, energy, and magnetic fields of the Earth.

Phone Physics: Using Cell Phone Sensors for Distance Learning Experimentation

The Advanced Laboratory Physics Association (ALPhA) had meetings with ~30 advanced lab instructors from around the US and the world in May 2020. Many of those instructors talked about how hard it was to transition to online or remote lab classes during the Spring when the COVID-19 pandemic hit and about their worries for the Fall. These instructors asked ALPhA for two things: 1) increased communication to allow instructors to share ideas or to team up to solve problems, and 2) a curated list/database/website/document of resources that includes instructors’ experiences. During June and July, ALPhA will focus on these two requests by facilitating member communication and posting instructor-curated resources. As secretary of ALPhA, I will report back about these resources and relay the most important take-aways. To get up-to-date information or to join the conversation, please visit the ALPhA website at advlab.org.

Resources from ALPhA for Fall 2020 Advanced Lab Classes

Many science instructors aspire to let students discover the laws of nature on their own but find it can be logistically difficult and time consuming to put in practice. In addition, the results are often more equivocal than one would hope. One practical way to let students discover how the universe works is using interactive video. Interactive video uses high resolution recordings of scientifically interesting events that students can characterize for themselves using built-in tools. In many cases, students can also change important parameters in the video (mass, frequency, velocity, pH, etc) which lets them ask their own questions, design their own experiments to answer those questions, and then collect and analyze the results to reach data-driven conclusions.
