When will objects float and when will they sink? Learn how buoyancy works with blocks. Arrows show the applied forces, and you can modify the properties of the blocks and the fluid.

This book will study a variety of classroom management theorists and their theories, noting the historical background of the theorist, a basic overview of the theory, and a professional critique of the theory. It will also discuss practical applications for the theories for both elementary and secondary classrooms.

Make a whole rainbow by mixing red, green, and blue light. Change the wavelength of a monochromatic beam or filter white light. View the light as a solid beam, or see the individual photons.

Why do objects like wood float in water? Does it depend on size? Create a custom object to explore the effects of mass and volume on density. Can you discover the relationship? Use the scale to measure the mass of an object, then hold the object under water to measure its volume. Can you identify all the mystery objects?

How did scientists figure out the structure of atoms without looking at them? Try out different models by shooting light at the atom. Check how the prediction of the model matches the experimental results.

Discover what controls how fast tiny molecular motors in our body pull through a single strand of DNA. How hard can the motor pull in a tug of war with the optical tweezers? Discover what helps it pull harder. Do all molecular motors behave the same?

Critical Perspectives on Open Education

Short Description:
This book represents a starting point towards curating and centering marginal voices and non-dominant epistemic stances in open education. It includes the work of 43 diverse authors whose perspectives challenge the dominant hegemony.

Long Description:
Open education is at a critical juncture. It has moved on from its northern roots and is increasingly being challenged from its own periphery. At the same time, it finds itself marginalised and under threat in an educational sector infiltrated by corporate interests. However, rather than bunkering down, becoming blinkered or even complacent, the editors of this volume believe that the voices from the periphery should be amplified. This book represents a starting point towards curating and centering marginal voices and non-dominant epistemic stances in open education, an attempt at critical pluriversalism. It is a curated collection of 38 blog posts, lectures, talks, articles, and other informal works contributed by 43 diverse authors/co-authors and published since 2013. Each of these contributions offers a perspective on open education that can be considered marginal and that challenges the dominant hegemony.

Did you ever imagine that you can use light to move a microscopic plastic bead? Explore the forces on the bead or slow time to see the interaction with the laser's electric field. Use the optical tweezers to manipulate a single strand of DNA and explore the physics of tiny molecular motors. Can you get the DNA completely straight or stop the molecular motor?

Create your own sandwich and then see how many sandwiches you can make with different amounts of ingredients. Do the same with chemical reactions. See how many products you can make with different amounts of reactants. Play a game to test your understanding of reactants, products and leftovers. Can you get a perfect score on each level?

How did Rutherford figure out the structure of the atom without being able to see it? Simulate the famous experiment in which he disproved the Plum Pudding model of the atom by observing alpha particles bouncing off atoms and determining that they must have a small core.

Explore stretching just a single strand of DNA using optical tweezers or fluid flow. Experiment with the forces involved and measure the relationship between the stretched DNA length and the force required to keep it stretched. Is DNA more like a rope or like a spring?

Short Description:
A workbook for bringing new voices into public debate based on the performance creation approach developed by Transforming Stories, Driving Change.

Long Description:
Can theatre bring new voices into public debate? Facilitating theatre workshops with community members who experience social marginalization is an art that, when done well, feels more like magic. But even the best facilitators are not magicians. With this workbook we pull back the curtain on the magic by taking readers behind the scenes of the Hamilton-based research and performance initiative Transforming Stories, Driving Change (TSDC.) Since 2015, TSDC teams have worked alongside community partners and performer-advocates to make plays designed to draw attention to the voices and visions of people whose opinions are not often represented in discussions of the future of the City. Through our performances, we have tried to contribute to building the movements that can make public leaders more accountable to people who are affected by their decisions. Five years and four plays later, we offer this workbook as a practical guide to TSDC’s creative approach.

Software Carpentry lesson on how to use the shell to navigate the filesystem and write simple loops and scripts. The Unix shell has been around longer than most of its users have been alive. It has survived so long because it’s a power tool that allows people to do complex things with just a few keystrokes. More importantly, it helps them combine existing programs in new ways and automate repetitive tasks so they aren’t typing the same things over and over again. Use of the shell is fundamental to using a wide range of other powerful tools and computing resources (including “high-performance computing” supercomputers). These lessons will start you on a path towards using these resources effectively.
