Sailing Stones

Multiple Representations in Kinematics

Thank you for participating in the webinar "Experience Kinematics: Using Data to Understand Motion." You will be using the features on this Google site to participate in the interactive components of the webinar. Please follow along and use the various tools as they are discussed. The video for the webinar is below.

Simplified Data

The first 5 minutes of the motion depicted in the middle panel of Figure 6 from the article is simplified and provided below.

Sailing Stone Motion

Analyzed Raw Data

The raw data linked above provides GPS coordinates for each second. I used the Haversine formula to convert this to position at each time step with the starting position assumed to be 0 meters. This provides classroom usable data for position and velocity as a function of time. The specific stone analyzed is "Maia" from the raw data with a mass of 8.2 kg. The data that was used for the phenomena revisits in Experience Physics was for the stone "Eos." See if you can use the Haversine Formula to get analyzed data for Eos.


Experience Physics

Students best learn science when they do science. That’s why this modern program puts the focus on the student experience. With Experience Physics, learning is based on doing science. This new program implements a learning model that:

  • Organizes learning around phenomena, giving students an authentic, real-world experience.

  • Includes a variety of hands-on and digital activities designed to reach every learner.

  • Partners with Flinn Scientific to deliver high-quality inquiry labs, engineering workbenches, and performance assessments.

  • Allows instructors to personalize their course by selecting from our activities or embedding their own

Multiple Representations in Chemistry

Having students move back and forth through multiple representations of the same phenomena is research-validated and pedagogically crosscutting. Check out a similar workshop we do for chemistry called "Experience Stoichiometry."
