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?

A teaching guide for teachers to instruct students in the gaming rules and procedures for Basic Wff'n Proof. This game teaches symbolic logic and problem solving. The content is an overview of the game of Wff'n Proof for interested coaches.

The PhET project at the University of Colorado creates "fun, interactive, research-based simulations of physical phenomena." This particular one deals with Beer's Law. "The thicker the glass, the darker the brew, the less the light that passes through." Make colorful concentrated and dilute solutions and explore how much light they absorb and transmit using a virtual spectrophotometer! The simulation is also paired with a teachers' guide and related resources from PhET. The simulation is also available in multiple languages.

This page provides access to the presentations and materials offered throughout the 2018 California Safety Organized Practice Conference, which was hosted by the Northern California Training Academy at the University of California, Davis June 26-27. The statewide conference provided an opportunity for counties implementing Safety Organized Practice (SOP) to explore strategies for rigor and depth of practice across the case continuum, and to share strengths, challenges and successes around implementation and sustainability.

This activity provides a demonstration and lab exploration of one of the main "building blocks" of the periodic table of elements: chlorine. During the lab, students compare physical and chemical properties of chlorine compounds.

This course’s aims are two-fold:

to offer students the theoretical and practical tools to understand how and why cities become torn by ethnic, religious, racial, nationalist, and/or other forms of identity that end up leading to conflict, violence, inequality, and social injustice; and
to use this knowledge and insight in the search for solutions

As preparation, students will be required to become familiar with social and political theories of the city and the nation and their relationship to each other. They also will focus on the ways that racial, ethnic, religious, nationalist or other identities grow and manifest themselves in cities or other territorial levels of determination (including the regional or transnational). In the search for remedies, students will be encouraged to consider a variety of policymaking or design points of entry, ranging from the political- institutional (e.g. forms of democratic participation and citizenship) to spatial, infrastructural, and technological interventions.

The fundamental concepts of inorganic chemistry including the physical and chemical properties of matter, atomic structure, chemical bonding, stoichiometry, the gas laws, solutions, acids and bases, redox reactions, and chemical equilibria. The laboratory includes an experimental study of the chemical principles. 3 hours lecture/3 hours laboratory.

This course will explore the state of the art in common sense knowledge, and class projects will design and build interfaces that can exploit this knowledge to make more usable and helpful interfaces.
This year’s theme will be about how common sense knowledge differs in different languages and cultures, and how machine understanding of this knowledge can help increase communication between people, and between people and machines.

Watch your solution change color as you mix chemicals with water. Then check molarity with the concentration meter. What are all the ways you can change the concentration of your solution? Switch solutes to compare different chemicals and find out how concentrated you can go before you hit saturation!

These are activities where students explore chemical reactions, as well as the effects of concentrated solutions.

In this electrochemistry activity, learners will explore two examples of electroplating. In Part 1, zinc from a galvanized nail (an iron nail which has been coated with zinc by dipping it in molten zinc) will be plated onto a copper penny. In Part 2, copper from a penny will be plated onto a nickel.

This course looks at all forms that energy exists. It explains how energy is used in: transport, agriculture, industry, commerce and households. It describes how energy is stored using storage systems such as: battery, flywheels, compressed air, chemical energy systems and pumped storage. This course explains the problem of depletion of energy resources. It describes the environmental damage associated with the use of fossil fuels, acid rains, dangers posed by leaded fuels, oil spills, gas leaks and explosions, water pollution caused by poorly managed coal mines, and air pollution. It describes the environmental damage associated with the use of fuelwood, uranium, hydro-power plants and wind. It also explains possible solutions to the energy-related problems.

The overall goal of the authors with General Chemistry: Principles, Patterns, and Applications was to produce a text that introduces the students to the relevance and excitement of chemistry.Although much of first-year chemistry is taught as a service course, Bruce and Patricia feel there is no reason that the intrinsic excitement and potential of chemistry cannot be the focal point of the text and the course. So, they emphasize the positive aspects of chemistry and its relationship to studentsŐ lives, which requires bringing in applications early and often. In addition, the authors feel that many first year chemistry students have an enthusiasm for biologically and medically relevant topics, so they use an integrated approach in their text that includes explicit discussions of biological and environmental applications of chemistry.

Students gain an understanding of the difference between electrical conductors and insulators, and experience recognizing a conductor by its material properties. In a hands-on activity, students build a conductivity tester to determine whether different objects are conductors or insulators. In another activity, students use their understanding of electrical properties to choose appropriate materials to design and build their own basic circuit switch.

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water. This lab asks learners to record measurements and make calculations related to volume, diameter, area, and height. Learners also convert meters into nanometers. Includes teacher and student worksheets but lacks in depth procedure information. The author suggests educators search the web for more complete lab instructions.

This activity helps students understand how mixtures are formed. They will make predictions regarding the rate of mixing. Students should report that the variation of heated water and crushed sugar creates the shortest mixing time.

To prosper, firms must develop major product and service innovations. Often, though, they don’t know how. Recent research into the innovation process has made it possible to develop “breakthroughs” systematically. 15.356 presents several practical concept development methods, such as the “Lead User Method,” where manufacturers learn from innovative customers. Expert guest speakers present case studies that show the “art” required to implement a concept development method. 15.356 is a half-term subject.

In this activity, learners investigate the speed of chemical reactions with light sticks. Learners discover that reactions can be sped up or slowed down due to temperature changes.

The website physics.gpclements.com has annotated lists of YouTube videos for both semesters of introductory physics. The lecture videos follow the order in the OpenStax Physics textbook. The level is suitable for high school and college students. There is a short (15 minutes or so) lecture for each topic and example problems that are worked out step by step. The site also lists a few calculus level physics videos. There is no charge for viewing the YouTube videos.

This Introductory Chemistry textbook was developed by the Chemistry faculty at Montgomery College, and provided by Professor Patricia Takahara. The book is meant for students with very little or no background in chemistry. Concepts here are presented at a very basic level in order to provide the foundation for college-level general chemistry. This book is used in Introductory Chemistry, a non-credit, preparatory course at Montgomery College (Maryland).
