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 resource is for teachers to develop their knowledge around climate science along with NGSS-aligned teaching strategies . Teachers can learn more about the following climate change impacts: coastal hazards, fire, human health, floods & droughts, agriculture and species & ecosystems. Users should reference the "STEM Seminar Slides_Template" as a guide for a daylong training and use the other materials as supplemental information and resources.

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.

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!

In this activity, learners conduct an oxidation experiment that turns old pennies bright and shiny. Learners soak 20 dull, dirty pennies in a bowl of salt and vinegar for five minutes. They rinse half the pennies with water, then compare the rinsed pennies to the unrinsed after all pennies sit and dry for about an hour. Learners also observe what happens when they submerge a screw and nail in the liquid compared to a nail only half-way submerged.

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 is a template of a STEM Seminar training focused on energy production & consumption and the relationship to climate change. This training typically takes place over the course of two days. This resource is driven by the Next Generation Science Standards. In particular the activities allow participants to practice various Science & Engineering Practices, such as "Analyzing and interpreting data." These resources also include a two-day agenda and a set of questions regarding the data. 

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.

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).
