The Dose makes the Poison

Prove the Law of Conservation of Mass through a lab investigation. A well-designed lesson asks groups to combine materials and monitor indicators for chemical reactions. Measuring the mass of the reactants and products allows individuals...

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...

Viewers learn how to identify the substances in a chemical reaction, how to balance it, and the different types of chemical reactions by watching a presentation that also includes a review of monomers and polymers. The presentation...

Wow! This comprehensive collection of slides will walk your chemistry class through the foundation of chemical reactions, teach them to balance equations, differentiate types of reactions, and calculate stoichiometry problems. This...

Does a concentrated solution or a diluted solution contain more particles? The 24th video in a 30-part series answers this question as an introduction to figuring concentration using the standard formulas. Through two different formula...

Does concentration affect the rate of a chemical reaction? Science scholars observe and control a chemical reaction in an interactive simulation. The resource allows pupils to add atoms to the reaction vessel and monitor the reaction's...

How well can your class concentrate on solutions? Scholars use colorimeter absorption to explore a starch concentration calibration curve. They add iodine to different starch solutions to see how the concentration of the solution changes.

Play a little game of concentration! A virtual lab investigation allows learners to predict the products and reactants of a DNA reaction. They make their calculations and then test their predictions in the lab workbench.

In this activity, students explore reactions in which chemical bonds are formed and broken. Students experiment with changing the temperature and the concentration of the atoms in order to see how these affect reaction rates. They also...

Learners investigate the reaction rate of iodine and soluble starch. In this rates of chemical reactions lesson plan, students study the effects of varying concentrations of reactants and varying temperatures of reactants on the reaction...
