This activity is acid-base titration lab where students determine the percent of calcium carbonate in an eggshell.
Learn about acids, bases and alkalis through engaging, bitesize animated videos. They are organised into these chapters: acids and bases, acid reactions, soluble salts, insoluble salts and uses of salts.
This activity must be conducted under the direct supervision of an adult familar with laboratory safety practices. Personal protection equipment, inlcuding goggles and apron must be utilized.In this exploration students will:recognize some acids and bases as common and familiar household chemicals.realize that acids and bases are not necessarily strong or dangerous.determine the pH of different chemical compounds and categorize them as acids or bases.investigate how the difference between acids and bases correlates to the difference in hydrogen ion concentration of solutions of the two classes of compounds.Link to lesson
This activity is a lab where students make qualitative and quantitative observation on a chemical change. They will see that gases have mass in accordance with the conservation of matter.

A work in progress, CK-12 Chemistry Teacher's Edition supports its Chemistry book covering: Matter; Atomic Structure; The Elements; Stoichiometry; Chemical Kinetics; Physical States of Matter; Thermodynamics; Nuclear and Organic Chemistry.
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.
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.
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 is an extension to standard labs that have students generate a pH curve from strong acid/strong base data. Students are asked to predict and test how the the titration end point will shift when titrating vinegar (a weak acid) with NaOH (a strong base).
A short activity using goldenrod copy paper as an indicator to introduce neutralization reactions. Students describe what they beleive happens during this reaction.
In this online activity, learners experience the thrill of pickle making, and explore how a cucumber becomes a pickle. In this "virtual kitchen," leaners discover that pickling takes practice to determine the best recipe (or conditions) for pickling cucumbers. These conditions include room temperature and amount of salt. Use this activity to help learners explore the science of cooking.
This unit includes 10 lessons that culminate in a student created final product presentation on the factors that influence climate change through the lens of chemistry and oceanography using literacy strategies to conduct inquiry level research.
Using inquiry-based reading, student will examine an anchor text to formulate a question to guide their research and development of student driven projects. Throughout the unit, students will use a variety of texts, websites, and other resources to develop a product and presentation that exhibits their literacy and inquiry skills. Using inquiry-based reading, students will explore an anchor text and then develop their own essential and supporting questions to guide their research. Over the course of the unit, students will explore a variety of texts and grow in their knowledge of cellular organelles and in their ability to use informational text to support their inquiry and research.
Test the pH of things like coffee, spit, and soap to determine whether each is acidic, basic, or neutral. Visualize the relative number of hydroxide ions and hydronium ions in solution. Switch between logarithmic and linear scales. Investigate whether changing the volume or diluting with water affects the pH. Or you can design your own liquid!
