Content Videos (Lectures and animations to supplement lessons):
- Acid/Base Indicators
- Simple Properties of Acids and Bases
- Applications
Interactives (Online activities for student interaction & practice with content):
- Acids & Bases Activity (students click through this guided animation that teaches about acids and bases).
- Acids, Bases & Metals (students click through this guided animation that teaches about acids, bases and their reactions with metals)
- Acid/Base Solutions Simulation (students use this simulation to answer the question of how strong and weak acids differ by using various lab tools. 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?)
- SimLab: Acids and Bases (in this virtual lab, students use the indicator bromothymol blue to test five different solutions; the great part is that students click to see what’s happening on the molecular level to cause the color change!)
- Interactive pH Scale (students test the pH of things like coffee, spit, and soap to determine whether each is acidic, basic, or neutral. Students visualize the relative number of hydroxide ions and hydronium ions in solution, switch between logarithmic and linear scales, and investigate whether changing the volume or diluting with water affects the pH. Or they can design their own liquid!)
- Find pH of Acids, Bases and Salts (students manipulate variables such as types of acids, bases and salts as well as molarity and volume of solution, then immerse the virtual pH probeware to determine the pH of the solutions)
- Buffers (students create a buffer solution and test the pH)
- Acid/Metal Reactions: Virtual Experiment (students try their hand at adding three different metals to HCl and see what happens!)
- Acid/Base Reactions (students view this animated online tutorial about acid & base reactions)
Games (Online games for students to apply & test their content knowledge):
- ChemGameTutor: Acids & Bases (Dr. Despair has captured the top 12 chemists of all time! Students must choose the “Acids and Bases” Level and use their knowledge to set them free!)
- Match: Acids, Bases & Salts (match the names to the definitions; can be timed or untimed)
- Alien Juice Bar (This juice bar serves things like toothpaste juice, mouthwash juice, liquid soap juice and cough medicine juice to identify acids, bases and neutrals and show how they combine. In three challenges, find out which “juices” are most acidic, and learn more about pH levels)
- BioNetwork’s pH Training (in this game, students are tutored by Mr. Finley (a fish) about pH, and then given a quest to figure out how to solve the problem of his tank water being too alkaline by neutralizing the negatively charged ions!)
- Plant Extracts: Cabbage Juice (Use your knowledge of acids, bases and indicators to gather clues and perform this kitchen experiment!)
- Penalty Shoot-Out: Reactions, Acids & Alkalis (students must answer quiz questions correctly to try and shoot a soccer goal; get to choose your goalie and jersey colors!)
- Gridlocks (Gridlocks are a fun way to learn the facts you need in Chemistry. Unlock the grids to gain entry to the next level and a secure knowledge of the chemistry involved. Based on the ideas behind Su Doku, Gridlocks have a twist that makes them more interesting, more fun, and more useful.)
- Gridlocks: Level 1 (11-14s)
- Gridlocks: Level 2 (14-16s)
- Gridlocks: Level 3 (16-19s)
