### PRODUCT DESCRIPTION

This set of notes and homework are about pure substances existing in different states of matter and the points of change. Students will analyze graphs of different pure substances and estimate their points of change from the graph. It also allows students to understand that each pure substance exists in different states of matter depending upon how much kinetic energy the particles have. (Students have a misconception that the word freeze only applies to water). It also shows that the states of matter only exist with a temperature range for each substance.

Students have to analyze the graphs to determine the states of matter and then determine what a mixture of the substances would look like (states) at different temperatures. It is very helpful for students to apply the phase changes and the model of what the states of matter look like if the particles can be seen.

After students complete the first three pages for homework, I review the assignment and have them see a video on dry ice or bring in dry ice to show them if available.

Included in this homework are the new NGSS that apply to this homework and an explanation of how this assignment relates to the Standards, Disciplinary Core Ideas as well as the Practices. This particular assignment and notes provide for much of the Disciplinary Core Ideas and the practices (developing and applying models, and analyzing data) that will allow them to apply the information to the standards.

Lastly, there are extension questions with answers listed at the end that allow students to further apply the concepts.

NEXT STEPS:
I created a next HW called Gallium Phases HW. Feel free to download. It asks students to graph what happens to Gallium as heat is added, then asks them to make predictions. If you chose to follow me, I will post it as soon as I can. Thanks!
