Exploring a Chemical Reaction in a Toy - Student Laboratory Kit
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! Stud...
Natural Indicators - Acids, Bases, and the pH Scale - Guided-Inquiry Kit
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 sca...
Mystery Solutions with Acids and Bases -
Guided-Inquiry Kit
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 a...
What Is a Chemical Reaction? Student Laboratory Kit
Chemical change is a central part of our modern world. Although it is responsible for most of the energy, materials, and medicines that we depend on in our daily lives, chemical change may be mostly invisible to students. What is a chemical change? H...
Boning Up on Calcium - Microscale Analysis of Calcium in Milk - Student Laboratory Kit
Healthy body, good teeth, strong bones—the benefits of calcium in proper nutrition are well known. Why is milk promoted as an important source of calcium? Explore the chemistry behind the nutrition with this experiment that measures the amount of cal...
Swimming Pool Chemistry - Student Laboratory Kit
Anyone who has spent any time at the local pool has one “burning” question—“Just how much chlorine was added to this pool?” Swimming pool chemistry involves a rich variety of chemical concepts and practical applications. In this two-part experiment, ...
Microscale Silicate Garden - Super Value Kit
Your students will love to grow their own silicate crystal garden in microscale test tubes! In this kit, the crystal growing ability of 11 different metal salts in sodium silicate solution will be contrasted and compared. Students will be amazed by t...
Make Your Own Silver Mirror - A Microscale Super Value Laboratory Kit
Beautiful silver chemistry "mirrors" real-life applications of oxidation and reduction! Students create microscale silvered culture tubes by reacting silver-ammonia complex ions with dextrose. Dextrose is a reducing sugar—it reduces silver ...
Introduction to Acid-Base Titration - Student Laboratory Kit
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 in...
The Rate of Chemical Reactions - Student Laboratory Kit
This microscale version of the iodine clock challenge will surely spark inquiry-based questions in your lab! Students run and time eight trials simultaneously! The effects of concentration, temperature and a catalyst on the rate of an iodine clock re...
Iron(II) and Iron(III) Reactions - Student Laboratory Kit
Redox reactions are important not just in chemistry but also in biology and human nutrition. Help your students build vital connections between the sciences with this laboratory kit exploring the reactions of iron(II) and iron(III) compounds with oxi...
The Activity Series of the Elements - Student Laboratory Kit
The activity of zinc, copper, lead, magnesium and silver are tested. Small amounts of chemicals and metals produce less waste while still producing good results. The students will actually see more reactive metals going into solution while less react...
Chlorides, Bromides, and Iodides - Student Laboratory Kit
Through microscale qualitative tests, students will learn the properties, ways to identify, and test for three types of halides: chlorides, bromides and iodides. Qualitative analysis will give the student the knowledge necessary to identify chemical ...
Precipitation Reactions and Solubility Rules - Super Value Kit
All nitrates are soluble! Most hydroxides are insoluble! Rather than memorizing solubility rules such as this, students investigate precipitation reactions and then develop their own general rules of solubility—exactly what the National Science Stand...
Determination of Ksp for Ca(OH)2 - Student Laboratory Kit
Equilibrium and equilibrium constant calculations often confuse students. Use this microscale experiment to help students understand the relationship between the equilibrium constant and solubility. Students prepare serial dilutions of calcium nitrat...
Concentration and Molarity - Student Laboratory Kit
Students will use acid–base titrations to determine the concentration of unknown acid and base solutions in this laboratory activity. First, students will determine the concentration of an unknown hydrochloric acid solution by titrating with a THAM s...
Micro Mole Rockets - Hydrogen and Oxygen Mole Ratio - Student Laboratory Kit
The combustion reaction of hydrogen and oxygen has been used to send people to the moon and to design electric vehicles for the future. What factors determine the explosiveness of this reaction? In this microscale lab activity, students generate hydr...
Heats of Reaction and Hess's Law - Small-Scale Calorimetry Laboratory Kit
