Use class time to perfect your hollandaise sauce with a chemistry instructional activity. It includes two activities to teach about immiscible liquids, emulsifiers, and creating a stable homogenous mixture. Young scientists...

Radioactive decay, pH, properties of elements, organic compounds, and stoichiometry are all touched upon through this practice chemistry exam. It always helps learners to take a practice test in preparation for the actual exam. This...

In this chemistry worksheet, students examine a concept in science and then use the knowledge in application by conducting an experiment.

In this chemistry review worksheet, high schoolers answer a variety of questions about matter, elements, the kinetic theory, chemical and physical properties and the distillation process. They complete a concept map about matter.

Although there are only six questions on this chemistry handout, it makes a thorough review of solutions. Novices explain why a compound is not an electrolyte, identify types of compounds, and calculate moles, grams, and molalilties in...

Ready to mix it up? Learners step up to the plate and show what they know in the 12th installment of a 14-part series covering the states of matter. The quiz contains four questions testing the basics of emulsion chemistry.

Students explain the importance of the five main biogeochemical cycles. In this chemistry lesson, students discuss how ions are transported in the environment. They design an experiment to collect data on eutrophication.

Students predict the product of chemical reaction using the solubility rules. In this chemistry lesson, students balance ionic equation. They perform a lab to check if their predicted products are correct.

Students calculate the concentration of different solutions. In this chemistry lesson, students explain what a solution is. They explain ways to change the concentration of a solution.

The liquids did not mix — so what do density columns have to do with it? The seventh part in a series of nine provides the theoretical explanation of why density columns do not mix. The lesson plan covers the topics related to...

Students examine the rule of "like dissolves like." They define and describe solutions and solubility models on molecular liquids, ionic solids, and molecular solids.

Students are challenged to come up with a good estimate of the amount of air in foamed polystyrene products. They use this gas evolution experiment and as such have students measure the gas generated when foamed polystyrene is degassed...

Students investigate soap, how it is made and its structure. In this soap lesson, students observe a demonstration of soap being made. Students observe the properties of soap and how soap performs in "real-life" situations like cutting...

[Free Registration/Login may be required to access all resource tools.] Covers solubility in water and polar molecules.

After learners conduct the two associated activities, Density Column Lab - Parts 1 and 2, present this lesson to provide them with an understanding of why the density column's oil, water and syrup layers do not mix and how the concepts...

For this activity, students will test the solubility and miscibility of various substances in water, and explain the chemistry involved. They will also be given a solid and a liquid and asked to predict what will happen when each is...
