What is a chemist's favorite plant? Stoichiome Tree! Scholars produce hydrogen gas by reacting magnesium with hydrochloric acid. Then they calculate the molar volume of the gas produced before answering assessment questions. 

Lost an electron? You should keep an ion them. Young chemists learn qualitative analysis in the second lesson of an 11-part chemistry series. After observing reactions of simple salts, the teacher provides pupils with unknown...

Students experiment to determine the composition of ocean water. In this ocean water composition lesson plan, students color in a grid that shows the percentage of each of the components of ocean water which include chloride, sodium,...

Can you mix two liquids to make a solid that is insoluble? Yes, you can, and pupils see this as the lesson uses more than one combination of liquids to form a solid. Through two teacher demonstrations and a hands-on activity,...

In this chemistry worksheet, students find the outcomes necessary for the oxidation reduction reactions. The sheet includes background information.

There is a solvent called aqua regis that can dissolve gold! After observing a solubility demonstration, groups receive four known crystals and one unknown. Based on the demo, they design an experiment to determine the identity of the...

De-icing materials may have a harmful effect on our environment; have your class perform an experiment to test the nature of these effects. Scholars monitor the survival rate of a sample of daphnia as the concentration of a de-icing...

In this chemical reaction worksheet, students determine the rate of consumption or rate of production for given reactions. This worksheet has 14 problems to solve.

Sixth graders locate and identify the major bodies of water and waterways in the United States. Through a simulation activity, they describe how early explorers would have described their surroundings. Working in groups, they create...

In this chemical reaction worksheet, students write a balanced equation for each of the word equations given. This worksheet has 12 problems to solve.

In this stoichiometry worksheet, students solve several problems using the stoichiometric method. Students find the percent, theoretical, and actual yield for all problems presented.

Pupils describe limitations of fresh water resources on ships at sea. They realize the value of fresh water on the ocean and around the world. Students gain a knowledge of the process and economic cost of desalinization.

Students examine the different changes in matter.  In this chemical change lesson students determine the amount of reactant made in a reaction using the law of conservation. 

Students conduct labs to gain an overview of chemical reactions. They observe examples of synthesis, decomposition, single displacement and double displacement reactions. They identify certain products by the use of litmus and splint tests.

Learners define and discuss salinity, conduct classroom experiment to determine salinity of water sample by using hydrometer, record predictions, and demonstrate understanding of how salinity influences object's ability to float in water.

Learners observe crystals under the microscope. In this science lesson, students compare how the crystal look like using their eyes, hand lens and microscope. They identify the type of crystal based on the amount of light they allow to...

Fourth graders identify eleven white substances that are commonly found in the household. They, in pairs, perform experiments on a variety of substances, and must identify them based on the reactions they observe.

Pupils explore conductivity and productivity in aquatic systems.
