Students will understand how to calculate the equilibrium quotient to determine the direction of solubility and solid formation.
How do strong and weak acids differ? Use lab tools on your computer to find out! Dip the paper or the probe into solution to measure the pH, or put in the electrodes to measure the conductivity. Then see how concentration and strength affect pH. Can a weak acid solution have the same pH as a strong acid solution?
This course is inline with 2nd year engineering students who would like to understand the concepts of thermodynamics.
Play with objects on a teeter totter to learn about balance. Test what you've learned by trying the Balance Challenge game.
Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.
By the end of this section, you will be able to:Describe the basic types of ecosystems on EarthExplain the methods that ecologists use to study ecosystem structure and dynamicsIdentify the different methods of ecosystem modelingDifferentiate between food chains and food webs and recognize the importance of each

We can combine our knowledge of acids and bases, equilibrium, and neutralization reactions to understand buffers and titrations. Solubility equilibria will build on concepts from solubility, precipitation, and equilibrium.
This activity features calculations and rankings as well as student evaluations of their understanding. Instructions are provided on the document, which is ready for distribution to students. It was developed by Celestina A. Pangan and Madhu Gyawali.
It discusses the process of equation writing and balancing chemical equations in perspective of the chemical changes that take place during a reaction. This module is the third in a series on chemical reactions.
Bitesize, animated videos covering many chemical reactions topics, organised into these chapters: rates of reactions, equilibrium, redox, electrolysis and energetics through engaging, bitesize animated videos.
Introduction to engineering mechanics: statics, for those who love to learn. Concepts include: particles and rigid body equilibrium equations, distributed loads, shear and moment diagrams, trusses, method of joints and sections, & inertia.
A free and open source textbook for a traditional, one-semester, engineering mechanics (statics) course.
Topics include forces and moments; equilibrium of particles, rigid bodies, and structures; centroids and moments of inertia. The text contains interactive diagrams illustrating important concepts. A pdf version is at https://engineeringstatics.org/pdf/statics.pdf
Students explore the biosphere and its associated environments and ecosystems in the context of creating a model ecosystem, learning along the way about the animals and resources. Students investigate different types of ecosystems, learn new vocabulary, and consider why a solid understanding of one's environment and the interdependence of an ecosystem can inform the choices we make and the way we engineer our communities. This lesson is part of a series of six lessons in which students use their growing understanding of various environments and the engineering design process, to design and create their own model biodome ecosystems.
