AP7165 - $73.35
Welcome your students to the “wonderful world of chemistry!” Five colorful and engaging demonstrations have been selected to help students develop observational and critical-thinking skills—and to get them excited about the amazing science that lies...
AP7018 - $33.70
Watch paper chameleons magically change color with the help of some basic—and acidic—chemistry. Students spot solutions of various household substances on specially treated blotting paper, then estimate the pH of each by the color produced. Creativity...
AP7209 - $38.80
Experience the nature of scientific inquiry and scientific problem solving using this unique color change challenge lab! Students must discover a sequence of chemical changes—using four unknown colorless solutions—that will result in a series of specific...
AP7155 - $31.45
A rainbow spectrum of color changes provides visual proof of the effect of a catalyst. Hydrogen peroxide is added to two separate flasks, each containing a basic solution of sodium thiosulfate, along with universal indicator. One flask also contains...
AP7166 - $101.31
Put an exclamation point on your year-end review of chemistry concepts with this electric, entertaining, patriotic set of five demonstrations! • Passing electric current through a solution produces streaks of silver crystals that reverse course when...
AP6296 - $21.45
Watch as a colorless solution poured from a seemingly normal pitcher suddenly turns color! Here's how it works. A chemical is placed in a small fixed container located at the bottom of a pitcher. Another chemical is placed into the body of the pitcher....
AP1767 - $49.25
Buffers provide an essential acid-base balancing mechanism—in consumer products, foods, even living cells! What are buffers made of? How does a buffer work? Can you design a buffer to be effective in a given pH range? Is there such a thing as an ideal...
AP2046 - $19.70
Several titrations can be performed during one class period with surprisingly good results. Students determine the percentage of acetic acid in household vinegar by titrating the vinegar with a sodium hydroxide solution of known concentration. The...
AP6121 - $48.60
Proper pH is a true vital sign in the blood, in the lungs, and throughout the body! How do buffers maintain the delicate pH balance needed for life and health? Explore the properties of biological buffers in this two-part kit. In Part 1, students examine...
AP4567 - $60.10
Examine the properties of acids and bases with this high-quality kit. Students get a complete introduction to acids and bases. • Test acids and bases with litmus paper and phenolphthalein indicator. • Examine how pH is related to the strength of an...
AP4568 - $59.15
Explore acid-base reactions with this in-depth kit. Students learn about pH, acid-base indicators, antacids, neutralization, and titration as they perform six different experiments: • Study a neutralization reaction to make a simple salt. • Use antacids...
AP6364 - $30.25
Do your students understand why some acids have lower pH values than others, even though their concentrations are the same? Acids vary greatly in their strength-their ability to produce hydrogen ions when dissolved in water. This lab will help you...
AP6442 - $61.15
Roses are red, violets are blue—or are they? Red roses, as well as many other flowers and fruits, contain natural indicators that are sensitive to acids and bases. The color of a natural acid-base indicator depends on pH. In this activity, the pH scale...
AP7048 - $46.60
Investigate the chemistry behind an exciting “popping” toy. A chemical reaction within a sealed bag rapidly produces carbon dioxide gas, expanding until the bag breaks with a loud pop that will grab even your most inattentive student's interest! Students...
AP6690 - $23.95
Is orange juice more acidic than grapejuice What about pineapple juice? Fruit juices get their sweet taste from natural sugars and their sour taste from acids, especially citric acid. The balance of sugar to acid content give fruit juices their refreshing...
AP7444 - $40.50
Solve the acid and base mystery. Through deductive reasoning and microscale titrations, students learn the identity and concentrations of the four acid and base solutions. This guided-inquiry experiment can be adapted for various levels of students...
AP7602 - $125.40
Examine the properties of acids and bases with this high-quality kit. Students get a complete introduction to acids and bases. • Test acids and bases with litmus paper and phenolphthalein indicator. • Examine how pH is related to the strength of an...
AP7607 - $126.85
Explore acid-base reactions with this in-depth kit. Students learn about pH, acid-base indicators, antacids, neutralization, and titration as they perform six different experiments: • Study a neutralization reaction to make a simple salt. • Use antacids...
AP7636 - $103.95
Students carry out a series of dramatically colorful tests while they learn that: • Indicators can be acidic or basic. • Each indicator has a specific pH range. • Indicators can be combined to create a specific guide. • A color guide created by each...
AP7637 - $61.45
Swimming pools, lakes, our bodies-all require specific pH levels! Your students will gain a clear understanding of pH with this introductory kit. Students will test six indicators and record their colors in acidic and basic environments. Not only...
