General chemistry class members engage in a mini-unit on mole conversions. Through nine lab activites with varying degrees of difficulty, they practice measuring mass and volume, molar calculations, and stoichiometry. Terrific...

Learning about the mole using rice is pretty nice! Help your chemistry scholars visualize the concept of a mole of substance with an easy-to-perform lab. Partnered pupils find the mass of a single grain of rice and relate this...

You definitely want to check out this mole! Chemistry scholars experiment to observe an unobservable quantity with an engaging lesson plan from K20. Partners collaborate to determine what's inside an opaque box, then complete a series of...

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...

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

To wrap up your year of general chemistry, have lab groups compete in a tot wire chemical vapor deposition (HWCVD) competition. With their foundation in chemical nomenclature, stoichiometry, and gas laws, each group completes several...

How fun would it be to teach the concept of stoichiometry while allowing your chemistry class to assemble a classic campfire treat? This fun and engaging activity allows pupils to explore the principles of the chemical theory while...

Try not to blind anyone with science by following the safety rules. The lesson encourages scholars to form an ionic compound from magnesium and chlorine. Then they determine the empirical formula and determine the mole ratio and percent...

True friends stick together. In the case of The Wind In The Willows, the friends just happen to be a toad, mole, rat, and badger who team up to beat the weasels. The resource covers the first chapter of their raucous adventures. Scholars...

Acids and bases have a love-hate relationship. They balance each other so nicely, but they are complete opposites! Learners use these concepts and titration to calculate the molar mass of an unknown substance. The experiment...

Investigating the large numbers of science is the task in a simple but deep activity. Given a one-sentence problem set-up and some basic assumptions, the class sets off on an open-ended investigation that really gives some...

Why are acids and bases important in our daily lives? Lead the class in answering this question, among others, as they experiment with pH paper and classify where various substances belong on the pH scale. They also taste common acids...

Titration calculations require concentration. The 10th lesson in an 11-part series challenges young chemists to use titration in order to determine the molarity and mass percent in concentrated vinegar. Analysis questions encourage...

Watch as acids and bases put smiles on their faces. Young chemists learn the concept of acid-base titration firsthand in a microscale experiment. Working groups collaborate, titrate, then use their data to determine the concentration of...

What is a reasonable percent yield in the manufacturing process? Scholars develop a process for producing chalk in the third lesson of a six-part series. Then, they must determine the theoretical and percent yield. Discussions about...

Burrowing animals are busy! Get your middle school ecologists busy as well by having them create a scale model of a burrowing population. They also design a PowerPoint or poster to explain their models.
