Grade Level:  High School

Subject: Chemistry 1

Duration:  1 class period

DOK Level:  4

SAMR Level: Substitution

Indiana Standard:

• 11-12.LST.2.3: Follow precisely a complex multistep procedure when carrying out experiments, taking measurements, or performing technical tasks; analyze the specific results based on explanations in the test.
• 11-12.LST.5.2: Write informative texts, including scientific procedures/ experiments or technical processes that include precise descriptions and conclusions drawn from data and research.  
• 11-12.LST.7.1: Conduct short as well as sustained research assignments and tasks to answer a question, test a hypothesis, or solve a problem.

Objective:

• Students will learn the proper technique for using a mortar and pestle.
• Students will be able to write their own lab and determine what type of data to collect, complete with hypothesis, variable, control, equipment, procedure, and data table.  Then students will perform the lab they have written.

Procedure:

• Demonstrate the proper use of a mortar and pestle.
• Have students work in pairs or groups of 3 to write a lab, then have them perform it.
• Link to previous lesson.

Materials:  

• Mortar and pestle
• Ice
• Thermometers
• Various equipment as deemed necessary by students

Enrichment:  Rather than having students perform their own lab, have lab groups swap labs, write their own hypothesis, and follow the other groups directions.
