Lesson/Unit Plan

Overview:

In this lesson, students will be able to plan and carry out an investigation to identify which two of the three ingredients in baking powder react to produce a gas when water is added. Students will be able to explain that mixing substances can cause a chemical reaction that results in the formation of a new substance. Students will also be able to explain that substances react in characteristic ways and that the way a substance reacts can be used to identify the substance.

Content Standard(s):

Science
SC2015 (2015)
Grade: 5

4 ) Investigate whether the mixing of two or more substances results in new substances (e.g., mixing of baking soda and vinegar resulting in the formation of a new substance, gas; mixing of sand and water resulting in no new substance being formed).

NAEP Framework

NAEP Statement::
P4.3: Matter exists in several different states; the most common states are solid, liquid, and gas. Each state of matter has unique properties. For instance, gases are easily compressed while solids and liquids are not. The shape of a solid is independent of its container; liquids and gases take the shape of their containers.

NAEP Statement::
P4.4: Some objects are composed of a single substance; others are composed of more than one substance.

Unpacked Content

Scientific And Engineering Practices:

Planning and Carrying out Investigations

Crosscutting Concepts: Cause and Effect

Disciplinary Core Idea: Matter and Its Interactions

Evidence Of Student Attainment:

Students:

Conduct an investigation to determine whether the mixing of two or more substances results in new substances.

Teacher Vocabulary:

variables
states of matter
properties of matter
chemical change
physical change
evidence
temperature

Knowledge:

Students know:

When two or more different substances are mixed, a new substance with different properties may be formed.

Skills:

Students are able to:

From a given investigation plan, describe the phenomenon under investigation, including the mixing of two or more substances.
Identify the purpose of the investigation.
Describe the evidence from data that will be collected, including quantitative and qualitative properties of the substances to be mixed and the resulting substances.
Collaboratively plan an investigation and describe the data to be collected, including: how quantitative and qualitative properties of the two or more substances to be mixed will be determined and measured, number of trials for the investigation, how variables will be controlled to ensure a fair test.
Collect necessary data.

Understanding:

Students understand that:

Cause and effect relationships are identified and used to explain changes like those that occur when two or more substances are mixed together.
