 Graphs and Functions

Exploring States of Matter with Phase Diagrams
 Objectives: Students learn about carbon dioxide snowfalls on Mars by reading a NASA Press Release. They also learn about snow phase changes on Earth and the unique properties of water by watching a NASA eClips video segment. Students use formulae and graphs to quantify phase changes and explore relationships between temperature and energy.

Mathematics Skill or Topic Area:

Graphs and Functions

Next Gen Science Framework: PS1.A: Structure and Properties of Matter; PS1.B: Chemical Reactions; Patterns

Common Core ELA for Science: RST.6-8.2. Determine the central ideas or conclusions of a text; provide an accurate summary of the text distinct from prior knowledge or opinions. RST.6-8.8. Distinguish among facts, reasoned judgment based on research findings, and speculation in a text. RST.6-8.9. Compare and contrast the information gained from experiments, simulations, video, or multimedia sources with that gained from reading a text on the same topic.

Common Core Math Standard: CCSS.Math.Content.8.F.B.5 Describe qualitatively the functional relationship between two quantities by analyzing a graph (e.g., where the function is increasing or decreasing, linear or nonlinear).

Video Engagement: Phase Diagrams and Why you Cannot Make a Snowball on Mars  Join NASA scientists who study the History of Winter to learn about phase changes and the unique properties of water. Find out why ice floats and why this is important to life on Earth. See what pressure and temperature have to do with making snowballs. (7 minutes) View Program

Problem I - Exploring Energy and Temperature - Students learn how temperature is related to the amount of energy carried by matter in its various states. [Open PDF ]

Problem II - Exploring Temperature and States of Matter - Students Learn about how the states of matter change with temperature and pressure by working with a simple phase diagram for water. [Open PDF ]

Write your own problem - Using information found in the Math Connection problems, the press release or the video program, create your own math problem. Explain why you set the problem up this way, and how you might find its answer.

Challenge Problem - Students explore how pressure and temperature determine whether you can make a snowball on Mars. [Open PDF ]
