Activity that investigates phases of matter, effects of adding heat, mixing substances, and energy transformations using two PHET simulations from Phet.colorado.edu. Contains links to quickly access the simulations and multiple screenshots from the simulations to assist students in completing the activity. Most of my grade 9 students were able to finish in just less than one full class period (~45 minutes), though not quite all. My lower level students have also been able to complete, but required 2 full periods (110 minutes total). More or less time may be required based on the level of your students. FULL answer key included. MA State Standards Addressed 3.2 Explain how heat energy will move from a higher temperature to a lower temperature until equilibrium is reached. 3.3 Describe the relationship between average molecular kinetic energy and temperature. Recognize that energy is absorbed when a substance changes from a solid to a liquid to a gas, and that energy is released when a substance changes from a gas to a liquid to a solid. 3.4 Explain the relationships among temperature changes in a substance, the amount of heat transferred, the amount (mass) of the substance, and the specific heat of the substance.

PowerPoint and Guided Notes I use in my 9th Grade Introductory Physics class to teach about phases and the changes between them- solids, liquids, and gases. . Designed to accompany Pearson Science Explorer: Motion, Forces, and Energy Chapter 6 Section 3 about phase changes. Powerpoint is 16 Slides. Guided Notes are 3 Pages. Full color Answer Key included! Aligned to the following MA state standards for High School Introductory Physics: Particular focus on 3.3 but all are covered. 3.1 Explain how heat energy is transferred by convection, conduction, and radiation. 3.2 Explain how heat energy will move from a higher temperature to a lower temperature until equilibrium is reached. 3.3 Describe the relationship between average molecular kinetic energy and temperature. Recognize that energy is absorbed when a substance changes from a solid to a liquid to a gas, and that energy is released when a substance changes from a gas to a liquid to a solid. Explain the relationships among evaporation, condensation, cooling, and warming. 3.4 Explain the relationships among temperature changes in a substance, the amount of heat transferred, the amount (mass) of the substance, and the specific heat of the substance.

SAVE A BUNDLE!!! Buy them together! 4 Study guides for use as end of unit or end of year review including motion, forces, energy, heat, electricity, magnetism, and waves. 28 pages of questions (Some questions repeat between the individual study guides and the combined guide). Answer keys included for all!! Together they cover all of the introductory physics MA state standards.

Guided notes to accompany introduction PowerPoint (my primary free product!) and practice problems including solving for work and power, identifying when work is done, and a fill-in-the blank review section of vocab from work, power, force, etc. Designed to accompany: PowerPoint Introduction to work and power with examples and practice problems

Keep your kids engaged and turn a movie day into a day of quality notes! Worksheet of questions to accompany the Bill Nye the Science Guy episode on Phases of Matter! Answer key included!

Study Guide for my Heat Unit. Includes main ideas, essential questions, MA state standards, vocabulary list, equations, homework assignments, QR codes and links to resources, and learning checklist. Designed to Accompany Pearson Science Explorer: Motion, Forces, and Energy Chapter 6 but could be modified for any text. Word document for ease of modification.

Physics Final exam review worksheet with sections on Motion, Forces, Energy, Heat, Electricity, Magnetism, and Waves. 11 Pages Total with a table to review units and scalars/vectors at the end. Will require multiple days in class to complete. INCLUDES FULL ANSWER KEY!!!

This is the study guide I use with my students as they prepare for their unit test. The vocabulary includes a space for students to write the definitions as well as a space for them to draw a picture, write an example, or anything else that helps them remember. This is followed by heat review questions. Full answer key with work solved out and explanations included. Study guide including vocabulary is 7 pages long. Also includes 3 powerpoint slides including 2 days' activators and a slide of the daily objectives that accompany this unit. Vocabulary review suggestion - print out single sided. Put numbers on the back to match up the word and the definition. Cut out and play matching!! (Numbers allow students to check their matches).
