  Phase Changes, Sublimation, Physical Change, Density, Observations, Temperature | Middle School

  Lesson Plan: Dry Ice Mark as Favorite (0 Favorites)

  In this lesson, students will investigate how dry ice undergoes a phase change from solid to gas, skipping the liquid phase under normal temperature and pressure.

• 

  Exothermic & Endothermic, Chemical Change, Heat, Temperature, Classification of Reactions | Middle School, High School

  Lab: Designing Exothermic and Endothermic Reactions Mark as Favorite (20 Favorites)

  In this lab, students will design and test an experiment for producing either an endothermic or an exothermic reaction. The goal of the lab is for students to successfully construct a reproducible procedure for a reaction that either releases or absorbs thermal energy, and that can be supported with data.

• 

  Heat, Specific Heat, Temperature, Experimental Design, Scientific Method, Physical Properties | High School, Middle School

  Lesson Plan: Designing & Engineering a Fast Defroster Mark as Favorite (12 Favorites)

  In this activity students use their understanding of energy transfer to “design a solution to a complex real-world problem, based on scientific knowledge, student-generated sources of evidence, prioritized criteria, and tradeoff considerations.”  And “evaluate a solution to a complex real-world problem, based on scientific knowledge, student-generated sources of evidence, prioritized criteria, and tradeoff considerations.”  The real world problem is to help a cook who is trying to make a meal, but realizes some of the ingredients are frozen and must be thawed before he can begin.

• 

  Exothermic & Endothermic, Physical Change, Heat, Temperature, Observations, Intermolecular Forces, Solute & Solvent, Saturated/Unsaturated/Supersaturated | High School, Middle School

  Lesson Plan: Particle Modeling of Hand Warmers Mark as Favorite (22 Favorites)

  In this lesson, students will create a particulate model of matter that explains energy changes and transfer during a physical process, such as the crystallization of a solid from a supersaturated solution.

• 

  Phase Changes, Physical Change, Observations, Temperature | Elementary School, Middle School

  Lab: Condensation Mark as Favorite (2 Favorites)

  In this lab, students will explore the process of condensation. Students will investigate how water vapor condenses, and then they will conduct a comparison test to see if cooling water vapor has an effect on the rate of condensation.

• 

  Electricity, Law of Conservation of Energy, Anode, Cathode, Electron Transfer, Electrons, Subatomic Particles, Electrons | Middle School

  Lesson Plan: Battery Basics Mark as Favorite (11 Favorites)

  In this lesson students will explore the chemical reaction that occurs within a lead-acid car battery and the role of the battery within a car prior to creating their own batteries.

• 

  Separating Mixtures, Interdisciplinary, Electromagnetic Spectrum, Mixtures, Mixtures | Middle School

  Lab: Candy and Leaf Chromatography Mark as Favorite (13 Favorites)

  In this lab, students will learn that mixtures are created by the combination of two or more substances. Many colors are actually mixtures of several different pigments. Mixtures can be separated, and in this lab students will perform chromatography to separate mixtures found in candy and in leaves.

• 

  Atomic Spectra, Emission Spectrum, Emission Spectrum, Electromagnetic Spectrum, Interdisciplinary, Identifying an Unknown | Middle School, High School

  Lab: Build a Spectroscope Mark as Favorite (24 Favorites)

  In this lab, the students will make and use a spectroscope to identify the spectra within various types of light bulbs. The students will then develop an improved design for the spectroscope.

• 

  Chemical Change, Observations, Exothermic & Endothermic, Temperature, Chemical Change, Physical Change, Physical Properties | High School, Middle School

  Lab: Observing a Chemical Reaction Mark as Favorite (25 Favorites)

  In this lab, students will practice making careful observations and measurements while witnessing a chemical change.

• 

  Molecular Motion, Heat, Phase Changes, Melting Point, Heating Curve, Freezing Point, Temperature, Graphing | High School, Middle School

  Lesson Plan: Modeling the Melting of Ice Mark as Favorite (33 Favorites)

  In this lesson, students will create a particulate model of matter that explains energy changes and transfer during a phase change.

• 

  Exothermic & Endothermic, Classification of Reactions, Energy Diagrams, Bond Energy, Activation Energy, Temperature, Chemical Change | Middle School, High School

  Simulation: Energy Changes in Chemical Reactions Mark as Favorite (41 Favorites)

  In the November 2016 simulation, students will evaluate the energy changes in an endothermic and an exothermic chemical reaction. Students will have the opportunity to compare how energy is absorbed and released in each reaction, and will make a connection between the standard energy diagrams associated with each reaction type.

• 

  Heating Curve, Phase Changes, Intermolecular Forces, Freezing Point, Melting Point, Boiling Point, Heat of Vaporization , Molecular Motion, Temperature, Specific Heat, Heat, Heat of Fusion | Middle School, High School

  Simulation: Heating Curve of Water Mark as Favorite (50 Favorites)

  In the May 2015 issue, students explore the heating curve for water from a qualitative and quantitative perspective. Students compare illustrations of each physical state depicted on the curve and calculate the energy required to transition from one state to another.
