Chemists consider a situation in which an ethanol producer needs to determine how much to add to t-butanol to prevent freezing during transport. They work in the laboratory to obtain the freezing point depression constant for the...

Here is a general chemistry worksheet that incorporates practical applications. Four questions employ critical thinking about solutions, boiling and freezing points, and molar mass. Your class will practice what they learn in class by...

Students define the term solution. They explain conservation of energy and energy transfer as it relate to how the milk solution became ice cream. Students are able to explain freezing point depression.

A teacher with talent has created a fun set of review questions on the changing states of matter. Cycle through 15 questions, multiple choice answers, and a monetary reward for guessing correctly. Use this game show PowerPoint to help...

I scream, you scream, we all scream for ice cream! Even high schoolers enjoy making ice cream. This laboratory exercise has them record the temperature changes throughout the process of liquid becoming solid, graph the results, and...

In this kinetic theory worksheet, students are given fifteen questions about gases and their kinetic energy, how temperature effects kinetic energy, and the results of changing conditions of gases on the kinetic energy. They convert from...

Students examine the processes of melting and freezing.  For this matter lesson students complete a lab in groups, discuss what they learned and view a teacher demonstration. 

Students observe and discuss the change of water to ice and back again. In this water and ice lesson, students observe the change in temperature and what happens when water freezes and turns to ice and vice versa.

In this weathering worksheet, students fill in 16 blanks with given terms about the types of weathering, the results of weathering and the causes of different types of weathering.

Students understand that most substances may exist as solids, liquids, or gases depending on the temperature, pressure, and nature of that substance. This knowledge is critical to understanding that water in our world is constantly...

Students are shown an experiment making ice cream while discovering the freezing point depression. There are questions for students to answer after the demostration.

Students list reasons why water is important and investigate and graph the freezing points of different solutions.

Students explore the concept of freezing point in an experiment that shows why salt is effective at clearing ice from roadways in the winter. In small groups, they compare the process of making homemade ice cream in plastic bags with and...

Learners investigate the changes that occur at the molecular level when a liquid becomes a solid. They freeze water in baby jars and observe the changes that occur in the process.
