# Interactive Examples

Dolores Gende's insight:

Interactive Examples (IE's) are quantitative homework problems whose "help" comes in the form of more questions. Eventually, enough information is given in the helps to work the problems, but we hope that as students work their way through these examples, they acquire some better understanding of how to approach these kinds of problems. In particular, we hope that these examples help students learn to develop problem-solving strategies that are based on conceptual understanding rather than equation manipulation. In fact, once the student correctly answers the initial problem, we present a recap of the solution in terms of sequential conceptual, strategic and quantitative analyses. Following the recap, we ask the student some conceptual follow-up questions to test understanding.

## How Building a Black Hole for Interstellar Led to an Amazing Scientific Discovery | WIRED

Kip Thorne looks into the black hole he helped create and thinks, “Why, of course. That's what it would do.”

This particular black hole is a simulation of unprecedented accuracy. It appears to spin at nearly the speed of light, dragging bits of the universe along with it. (That's gravity for you; relativity is superweird.) In theory it was once a star, but instead of fading or exploding, it collapsed like a failed soufflé into a tiny point of inescapable singularity. A glowing ring orbiting the

## Physics Interactives

Welcome to Physics Interactives! This section of our website features a collection of HTML5 interactive pages that allow a user to explore a physics concept. Some Interactives are simulations that allow a user to manipulate an environment and observe the effect of changes in variables upon the simulation. Other Interactives are skill building exercises in which a user practices a skill that is crucial to learning some aspect of physics. And still other Interactives provide game-like environments that require the user to use a physics concept to meet a challenge. The Interactives are intended to be used by the individual student or learner who is attempting to further understand the concept or by a teacher-led classroom as part of a lesson or homework assignment. Most of the Interactives are accompanied by an activity sheet that suggests ways to use the widget.

## Physics Invention Tasks

Dolores Gende's insight:

We develop tasks in which students use data from contrasting cases to invent ratio or product quantities, rules or equations to characterize a variety of physical systems. Students work through sequences of such tasks to ramp up from everyday contexts to more abstract physics contexts.

## Blue Physics

Dolores Gende's insight:

Blue Physics by David Derbes is a free textbook (PDF), released under a Creative Commons license.

It is intended to be a "teach yourself" text for adults, covering first year college physics.
Knowledge of high school algebra is a prerequisite; calculus is taught as needed.
No prior knowledge of physics is presumed.

The book has many historical notes and worked examples. Internal references are hyperlinked.

## McCulley's HTML 5 Physics Lab Simulations

The simulations listed below are programs that I wrote for my students to use in lab as a complement to a live part of the lab. These programs were written to work on computers, tablets, phones and other handheld devices with HTML 5 capable browsers. All functionality for these programs comes from using the mouse or the touch screen an no keyboard usage is required.
