5-PS1-3

SCUSD NGSS Curriculum Guide


 * 5-PS1-3: Make observations and measurements to identify materials based on their properties. ** [Clarification Statement: Examples of materials to be identified could include baking soda and other powders, metals, minerals, and liquids. Examples of properties could include color, hardness, reflectivity, electrical conductivity, thermal conductivity, response to magnetic forces, and solubility; density is not intended as an identifiable property.] [//Assessment Boundary: Assessment does not include density or distinguishing mass and weight.//]

Science Background for the Teacher:
For this age group, the purpose of the activities are to identify substances by their properties (example: does wood conduct electricity? does metal? which is better for it?). Students do not have to measure how much of something is conducted. Keep data charts to "yes" or "no" and be able to write about the evidence.

Key Vocabulary:

 * reflectivity || electrical conductivity || thermal conductivity || magnetic forces ||
 * solubility || metals || minerals || liquids ||

Possible Assessments (formative and/or summative):
Give students a "mystery" powder and have them figure out what the powder is based on its properties reflecting back to their data from previous class investigations. Use this assessment after completing FOSS Grade 5 Investigation 3.

Corresponding FOSS Assessments

Key Student Activity:
FOSS Grade 5 Investigation 3. Students will need the data from these activities to complete the suggested assessment.

FOSS Grade 4 Investigation 2 "Conductors and Insulators"

FOSS Grade 4 Investigation 1 (all) "The Force"
