What better way is there to introduce conservation of mass than a few simple experiments? Young chemists conduct two chemical reactions, take the masses of reactants and products, then compare their results to determine...

Colorful lead compounds never fail to impress! Solubility scholars examine a series of double replacement reactions involving lead nitrate and record their observations. The second part of the experiment illustrates the differences...

In this redox reaction worksheet, high schoolers perform a redox titration to determine the number of iodide ions that react with each mole of iodate (V) ions in a solution. They calculate their answer using a given equation.

The more you know, the better your predictions! Using a hands-on lab experiment, collaborative groups collect information about ionic interactions. They record data describing the precipitate of reactions and use their information to...

Use chemistry to change pennies into gold coins! The experimental procedure leads learners through the process of changing copper pennies to silver and then to gold. They record the mass of each coin through every step of the experiment.

Accomplished chemistry learners set up a calorimeter and measured the energy released by various alcohols: methanol, ethanol, and either propanol or butanol. Lab masters will first need to design their tables for recording data. Consider...

In this volumetric analysis learning exercise, high schoolers use a standard solution they made of sodium carbonate to find the concentration of a hydrochloric acid solution by titration. Kids calculate the number of moles of sodium...

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...

Your chemistry class set up six different redox reactions in the lab. Inquisitors methodically test each one and eventually order them according to oxidizing strength. This is a neat way to have the learners perform more than one...

Here is a laboratory exercise in which chemistry masters conduct an oxidation reaction to change ethanol into ethanal. They compare the original alcohol to the resulting aldehyde by forming a precipitate. This activity is aimed at...

In this titration learning exercise, students calculate the moles of acids in a given amount of solution, balance equations, and calculate the concentrations of given acids. There are 10 problems to solve.

On Earth, a candle flame points up, but on the International Space Station, it forms a sphere. Young scientists practice their skills by recording observations before, during, and after a candle burns. Chemical and physical...

What do budding scientists know about moles and reactions? Using an attention-grabbing lab experiment, young scholars collect data to apply the law of conservation of mass to predict the mass of gaseous products. They examine several...

Melting and burning might seem like opposites, but both exist as common examples of exothermic reactions. Scholars work with three different exothermic chemical reactions to determine the enthalpy changes. They measure and mix chemicals,...

Challenge young scientists to design their own experimental procedures. They write the procedure for properly preparing two grams of a water-insoluble ionic salt. To finish, they perform the experiment and collect data to prove their...

In this complex salt worksheet, learners create teraamminecopper(II) sulfate · 1 · 2H₂O using copper(II) sulfate, concentrated ammonia, and ethanol. Students determine the formula mass for their product, the theoretical yield of the...
