Overview

An object’s pH level can be tested using indicators. Objects with a low pH are acids, and those with a high pH are bases. Acids and bases react together to form water and salt.

The classroom resource provides a video that will introduce students to pH levels, acids, bases, and their possible reactions. This resource can provide background information for students before they conduct their own investigations. There is also a short test that can be used to assess students' understanding.

SC15.2.4

Provide evidence that some changes in matter caused by heating or cooling can be reversed (e.g., heating or freezing of water) and some changes are irreversible (e.g., baking a cake, boiling an egg).

UP:SC15.2.4

Vocabulary

  • Properties
  • Evidence
  • Change
  • Matter
  • Heating
  • Cooling
  • Reversible
  • Irreversible

Knowledge

Students know:
  • Characteristics of materials before heating or cooling.
  • Characteristics of materials after heating and cooling.
  • Characteristics of materials when heating or cooling is reversed.

Skills

Students are able to:
  • Analyze evidence to support a claim that heating and cooling causes change in matter.

Understanding

Students understand that:
  • Heating or cooling a substance may cause changes that can be observed. Sometimes these changes are reversible and sometimes they are not.

SC15.5.3

Examine matter through observations and measurements to identify materials (e.g., powders, metals, minerals, liquids) based on their properties (e.g., color, hardness, reflectivity, electrical conductivity, thermal conductivity, response to magnetic forces, solubility, density).

UP:SC15.5.3

Vocabulary

  • color
  • hardness
  • reflectivity
  • electrical conductivity
  • thermal conductivity
  • response to magnetic forces
  • solubility
  • density
  • measurement (quantitative and qualitative)
  • data
  • observable properties
  • standard units
  • conductors
  • nonconductors
  • magnetic
  • nonmagnetic

Knowledge

Students know:
  • Materials have different properties-color, hardness, reflectivity, electrical conductivity thermal conductivity, solubility, and density.
  • Measurements of a variety of properties can be used to identify materials.
  • Measurements should be made in standard units (e.g., grams & liters).

Skills

Students are able to:
  • Identify the phenomenon through observations about materials, including color, hardness, reflectivity, electrical conductivity, thermal conductivity, response to magnetic forces, and solubility.
  • Identify the evidence and collect data about the observed objects in standard units (e.g., grams, liters).
  • Collaboratively plan the investigation.
  • Identify materials based on their properties.

Understanding

Students understand that:
  • Standard units are used to measure and describe physical quantities of materials such as weight, time, temperature, and volume. These measurements will assist in the identification of the materials ( e.g. powders, metals, minerals, and liquids).

SC15.5.4

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).

UP:SC15.5.4

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.
