The University of the State of New York has designed a series of exams to be given to high schoolers. This chemistry exam is one of the most comprehensive and well-written that you will ever find. It consists of 84 questions in a variety...

The 2006 version of the Regents High School Exam is just as thorough as the rest of them! Assess chemistry learners on an entire year's curriculum when they take this thirteen page test. 

Here's proof that small-scale labs lead to big-time learning. Introduce acid-base interactions to middle school scientists through a microscale chemistry lab. Pupils combine a variety of solutions and use indicators to obtain approximate...

Students evaluate pH levels through a solubility experiment. In this pH levels lesson, students list characteristics of acids and bases. Students complete their own pH level experiment. Students go to the GEMS Alien Juice Bar website to...

Young scholars investigate buffers and their behaviors when used with acids and bases. For this buffers lesson plan, students use a pH meter and create buffered acidic and basic solutions. To each of the buffered solutions young scholars...

For this acid and base worksheet, students test 13 different substances to determine their pH, the type of acid or base they are, the color the universal indicator turns, the color red litmus paper turns, and the color blue litmus paper...

Learners investigate 3 types of soap. In this properties of soaps lesson plan, students test soap with pepper and observe the reaction between the two. They make observations of the 3 types of soaps and make a chart to compare each. They...

Young scholars explore what chemical indicators are and use pH paper to determine if something is alkaline or basic.  In this pH lesson students manufacture their own soap.

Students set up and run the experiments they designed in the lesson, 'Population Growth in Yeasts,' using simple yeast-molasses cultures in test tubes. They demonstrate understanding that several environmental factors can contribute to...

Tenth graders are provided with a piece of paper such as index, art, construction, or computer coating it with a universal indicator. They use cotton swabs HCl and NaOH to draw a picture repeating the same process using lemon juice and...

In this indicators worksheet, students write equilibrium equations, determine the pH at the transition point of the indicator, and calculate the value of pKa. This worksheet has 7 problems to solve.

What did one titration say to the other titration? We should meet at the end point! Young chemists perform four experiments: dilute solution, neutralization, titration, and figuring pH/pOH. 

Over a 10-year period, EPA regulations cost businesses less than $30 billion, while businesses saved over $82 billion. Scholars experiment with acids and bases to better understand the pH scale. Then they debate environmental regulation...

Middle schoolers participate in a science lab to determine the pH of three different soil samples. Students conduct an experiment by creating a question, a hypothesis and then an investigation of soil samples. Then they compare colors...

Eighth graders design and perform an experiment that uses a Universal Indicator Color Guide to measure the strength of acids and bases. They also determine happens when acids and bases are mixed together. They decide which of three...

Looking for an easy way to give your class experience with acid-base chemistry outside the lab? Try a detailed interactive that puts them in total control! Young chemists determine the dissociation constant and concentration of an...

After demonstrating the use of cabbage juice as a pH indicator, have your class experiment with their own breath, exhaling into the indicator, to show that carbon dioxide is acidic. As learners work, they also watch a video about coral...

In this chemistry worksheet, students complete 5 multiple choice questions by selecting the correct answer from the drop down box.

Pairs work together to determine whether unknown solutions are either acids or bases by using a red cabbage indicator solution. After determining the general pH of the unknown solution, classmates blow into the same indicator after...

In this solutions worksheet, students calculate the pH of given solutions. Students determine the equation used to determine pH and the estimated pH for mixtures. This worksheet has 12 fill in the blank and 15 problems to solve.

Will this water source support life? Small groups test the chemistry of the water drawn from two different sources. They then compare the collected data to acceptable levels to draw conclusions about the health of the source. The...

From their sweat to the water vapor in their breath, astronauts recycle every possible drop of water while in space. After watching a short video describing the different ways materials are recycled and reused in space...

Young scholars explore acids, bases, and indicators. They observe the various colors of an acid-base indicator solution and the neutralization of an acidic solution by an antacid.

Students describe characteristics and common uses of acids and bases. They describe the role of natural indicators in the chemistry of acids and bases after testing and making observations on a variety of plant extracts. Students observe...
