Students can use Self-Inflating Balloons to make observations and measurements to identify materials based on their properties.
Students can use Self-Inflating Balloons to plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.
Using the Self-Inflating Balloons, students can to analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
Students can use Self-Inflating Balloons to analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.
Using the Self-Inflating Balloons, students can construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
Developing Possible Solutions. Both Physical models (Self-Inflating Balloons) and computers can be used in various ways to aid in the engineering process.
Students can use Self-Inflating Balloons to plan and conduct an investigation to describe and classify different kinds of materials by their observable properties. Two Self-Inflating Balloons allow students to make observations, make a claim and revise ideas based on new observations of the second balloon.
