If you have taught the first instructional activity in this mini unit, learners already know that cabbage juice and vinegar cause chemical changes in some materials. Now, they get a chance to use them to compare the liquids' reactions to...

Looking for a terrific chemistry lesson plan for your 5th graders? This one could be for you! After a teacher-led demonstration, learners are broken up into groups and perform an experiment using cabbage juice, water, window cleaner, and...

By both demonstration and hands-on investigation, physical science fanatics come to know that some materials react when they come together. Adding vinegar to both baking soda and to baking powder, the difference between the two is clear....

Get big results out of a small-scale lab! Young chemists observe the electrolysis of sodium sulfate using a microscale experiment. A colorful indicator solution combined with the production of gas bubbles yields a variety of observations...

Is assembling the periodic table as simple as Tetris? Scholars arrange colored cards into a logical order and then make connections to the arrangement of the periodic table. Hands-on activities include adding trend arrows and analyzing...

Equip your chemistry class with the tools to properly understand endothermic and exothermic reactions. Young chemists collect, analyze, and graph data to determine how the Law of Conservation of Matter is applied to chemical...

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...

Getting back to the beginning of the unit, learners use reactions with red cabbage juice to determine if solutions are acidic, neutral, or basic. This is a straightforward and classic investigation, but what you will appreciate is the...

Conclude this chemical change unit by having your class combine two liquids that result in formation of a precipitate. The learners discover that chemical reactions result in new materials. Make sure to consider all of the preceding...

Using the natural pH indicator of red cabbage juice, groups determine the pH of different everyday liquids. As they work, pupils gain an understanding of pH that may help deal with contaminants in the water supply. 

The best part of learning about equilibrium is that nothing changes. Young chemists observe four demonstrations during this lesson: equilibrium in a saturated solution, equilibrium with an acid-base indicator, equilibrium with cobalt...

Household materials can be used for more than cleaning! In this collaborative experiment, emerging chemists use products such as vinegar and liquid antacid to explore chemical reactions that commonly occur in the human body.

Several factors affect the rate of a chemical reaction including temperature, surface area, and concentration. Using an experimental approach, learners explore the effect concentration has on this rate while maintaining consistency with...

Did you know strong bases can feel slippery and slimy? Lesson allows scholars to practice using the pH scale to identify acids and bases and their strengths. By changing the concentration of an acid and a base, they create the entire...

Upcoming chemists use chemical reactions to determine relative pH in two different acids. This is a terrific lesson for middle schoolers that can stand alone as a practice in precision and lab skills, or as part of the unit on chemical...

Introduce high schoolers to chemical reactions with this series of activities. In a little over an hour, scientists observe four gas-producing reactions: the combination of hydrochloric acid and sodium hydroxide, placing pasta in...

During a three-part lesson plan, learners make a cabbage juice pH indicator and use it to analyze the waste products of yeast after feeding them with sugar. The intent is to demonstrate how living organisms produce carbon dioxide, which...

Now that your science class has experimented with pH indicator and identified acids and bases, they attempt to get the cabbage juice indicator back to its original color. This is done through neutralization of the acids and bases that...

Environmental science classes read articles about two different scientific studies. One is about the effects of contraceptive chemicals on fertility, and the other is about how a pesticide may be reducing bone density in exposed...

More than anything, this is great practice in scientific inquiry. After discovering that the color coating of an M&M® dissolves in water during a preceding activity, investigators now question whether or not the color makes a...

Some say cooking is an art—and a science! Scholars scope out the savory subject of molecular gastronomy with a series of related activities. The teacher's guide contains printable worksheets and helpful tips for implementing the lesson.

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...

Stoichiometry sounds complicated, but it really means the study of the amount of substances involved in a reaction. The sixth lesson in an 11-part series has scholars use stoichiometry to find the theoretical yield of a reaction. Then,...

The radical reactions of polymers seems abstract to many pupils, but this lesson turns them into a fun building game. Scholars use dice and building pieces to build polymers. Then, they determine the theoretical and experimental weight...
