Strand 6.2: Energy Affects Matter

Matter and energy are fundamental components of the universe. Matter is anything that has mass and takes up space. Transfer of energy creates change in matter. Changes between general states of matter can occur through the transfer of energy. Density describes how closely matter is packed together. Substances with a higher density have more matter in a given space than substances with a lower density. Changes in heat energy can alter the density of a material. Insulators resist the transfer of heat energy, while conductors easily transfer heat energy. These differences in energy flow can be used to design products to meet the needs of society.

6.2.2

Develop a model to predict the effect of heat energy on states of matter and density. Emphasize the arrangement of particles in states of matter (solid, liquid, or gas) and during phase changes (melting, freezing, condensing, and evaporating).
A balloon-covered flask with water in it is heated. Changes are recorded. There will be changes in the states of matter and a volume change while the total mass stays the same.
• Candy Bar Density
Once students have had an introductory density lesson and practice calculating density from mass and volume measurements, this lesson serves as follow-up to allow students to think critically about what makes one object more or less dense than another and to conduct an experiment to measure density of similar objects.
• Density Field Trip
Students will be taken around to different rooms in the building and analyze the density of the students in that area.
• Heating Up
This is a three part exploration which allows students to investigate the relationship between heating and cooling materials and their related expansion and contraction properties. They will also investigate the relationship between temperature and motion.
• Live Class Model of the States of Matter
This is a model where the students act as molecules to show the arrangement of particles in the 3 states of matter. An extension is done to show the motion of the particles relative to the state, and how temperature also affects motion and arrangement. This activity can be done by having class discussion and drawings on the board or using the more detailed student sheet.
• Phases Action Heroes
Students will design an “action Hero” based on the characteristics of a solid, liquid or gas.
• Physical State Diagram
Students will draw and describe what each of the physical states of matter is like.
• RAFT of Matter Change
The students will choose one box from each category and write a RAFT about the event.
