SC.8.P.9.3

Investigate and describe how temperature influences chemical changes.
General Information
Subject Area: Science
Grade: 8
Body of Knowledge: Physical Science
Idea: Level 3: Strategic Thinking & Complex Reasoning
Big Idea: Changes in Matter - A. Matter can undergo a variety of changes.

B. When matter is changed physically, generally no changes occur in the structure of the atoms or molecules composing the matter.

C. When matter changes chemically, a rearrangement of bonds between the atoms occurs. This results in new substances with new properties.

Clarification for grades K-5: The target understanding for students in the elementary grades should focus on Big Ideas A and B.

Clarification for Grades 6-8: The target understanding for students in the middle grades should begin to transition the focus to: C. When matter changes chemically, a rearrangement of bonds between the atoms occurs. This results in new substances with new properties.

Lesson Plans

Temperature and Chemical Reactions:

In this lesson students will investigate how temperature influences chemical reactions. Students will conduct an investigation and complete a simulation to determine what is happening at the molecular level of a chemical reaction when there is a change in temperature.

Type: Lesson Plan

Timing is Everything for Reactions!:

This predict, observe, and explain lesson allows students to investigate the influence of temperature on the rate of reactions. Students will have the opportunity to perform a lab activity that will help them discover that as temperature increases, so does reaction rate. This lesson includes a reaction rate demonstration, probing questions throughout the lesson, a meaningful class discussion, and a final product. Students will use what they've learned in the lab, to apply it everyday examples where reaction rates are influenced by temperatures.

Type: Lesson Plan

Faster Phizz:

This activity allows students to test the reaction rate of a chemical change using an effervescent tablet in different temperatures of water.

Type: Lesson Plan

Chemical or Physical Change? That is the Question!:

Students will conduct an investigation on the effect of laundry detergent on water temperature, use technology to graph their data, and determine whether a physical or chemical change occurred. Students will also read articles to gather evidence to write an evidence-based claim using the CLEVER method.

Type: Lesson Plan

Tranquilizer Chemistry - Temperature and Reaction Rates:

Students must select a tranquilizer dart to be used by the US Fish and Wildlife Service for researching large animals. Next, they must help the US Geological Survey choose a new drilling device. Each projectile has varying characteristics based on the temperature of the chemicals inside. Students must select which temperature lends itself to a reaction suitable for service in animal research or geological studies. Other factors due to temperature come into play as well, such as density and melting point.

Lord of Fries Conservation MEA:

This is an 8th grade MEA. This MEA will ask students to investigate different types of hamburger patties and choose the one that is best for the restaurant. Some of the areas that students will examine is how the hamburger patties undergo a chemical change, but mass is not lost only changed into different substances. They will also investigate how the hamburger patties are chemically changed due to a change in temperature. Students will also be exposed to how the Law of Conservation of Mass is used in our daily lives. For example, cooking a hamburger patty, the mass is not lost but sometimes the juices are separated from the meat. Also, in French fries, matter is not created but cooking oil is absorbed by the fries.

Type: Lesson Plan

The Effect of Temperature on Chemical Changes:

Students will describe how temperature influences chemical changes.

Content statements:
- Increasing the temperature will cause chemical changes to occur faster.
- Decreasing the temperature will cause chemical changes to occur slower.

Unit/Lesson Sequence

Middle School Chemistry Unit | Chapter 6 | Chemical Change:

Students explore the concept that chemical reactions involve the breaking of certain bonds between atoms in the reactants, and the rearrangement and rebonding of these atoms to make the products. Students also design tests to investigate how the amount of products and the rate of the reaction can be changed. Students will also explore endothermic and exothermic reactions.
