• 

  Separating Mixtures, Physical Change, Mixtures, Physical Properties, Experimental Design, Scientific Method, Error Analysis | High School, Middle School

  Lab: Separation of a Mixture

  In this lab, students devise their own method to separate a mixture of sand, salt, poppy seeds, and iron filings.

• 

  Polarity, Mixtures, Intermolecular Forces, Intermolecular Forces, Physical Properties, Observations, Mixtures | Middle School, Elementary School, High School

  Lab: Salad Dressing Science: Emulsions

  In this lab, students mix polar and nonpolar substances and then add various emulsifiers to encourage the mixing of the two substances. They use ingredients in salad dressing to relate science to real life scenarios.

• 

  Periodic Table, History, Physical Properties, Chemical Properties, Atoms, Model of the Atom, Atomic Radius, Subatomic Particles, Electrons, Valence Electrons, Electron Configuration, Orbitals , Isotopes, Atomic Mass | High School, Middle School

  Activity: Ptable.com Investigations

  In this activity, students will use the online periodic table found at www.ptable.com to investigate a number of chemistry concepts. Students will use this online resource to explore information about the elements, including historical data, physical properties, periodic trends and more.

• 

  Polymers, Scientific Method, Physical Properties, Mixtures | Elementary School, Middle School

  Lab: Polymer Investigation

  In this lab, students will follow the procedure for creating a polymer, flubber, which will be similar in consistency to Silly Putty. Students will then design an experiment to test a physical property of the flubber that they have created using the scientific method.

• 

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

  Lesson Plan: Designing & Engineering a Fast Defroster

  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.

• 

  Density, Error Analysis, Accuracy, Identifying an Unknown, Physical Properties | High School, Middle School

  Lab: Density Lab

  In this lab, students determine the density of several liquids and solids. They then identify an unknown metal by determining its density. They then calculate the percent error within the class for a specific sample.

• 

  Periodic Table, Elements, Matter, Physical Properties, Chemical Properties, Observations, Identifying an Unknown | High School, Middle School

  Lab: Periodic Table Trends

  In this lab, students will investigate trends of the periodic table by examining samples of six elements. Students will use observations about the elements’ appearance, conductivity, and malleability to determine whether they are metals, nonmetals, or metalloids. They will also see how these elements, as well as two more in a teacher demo, react with water and use this information to make claims about reactivity patterns in the periodic table.

• 

  Mixtures, Physical Properties, Molecular Structure, Mixtures | Elementary School, Middle School, High School

  Demonstration: Analyzing Mixtures

  In this demonstration, the teacher will create a sequence of mixtures in a single test tube. Water, oil, food coloring and soap will be used in this demonstration to introduce the concepts of heterogeneous and homogeneous solutions as well as the idea of miscibility. Students will also have the opportunity to analyze the properties, such as surface tension of each component used.

• 

  Chemical Change, Identifying an Unknown, Physical Properties, Chemical Properties, Chemical Change, Experimental Design, Scientific Method | High School, Middle School

  Lab: As Easy as Pie

  In this lab, students will use chemical and physical properties to identify an unknown powder.

• 

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

  Lab: Observing a Chemical Reaction

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

• 

  Culminating Project, Review, Physical Properties, Chemical Properties, Periodic Table, History, Interdisciplinary, Electron Configuration, Subatomic Particles, Isotopes, Atomic Mass | High School, Middle School

  Project: 21st Century Elements

  In this project, students will learn the importance of the elements in our lives. The students will research one chosen element and create a website, a digital comic strip, or a video to explain the important properties of the element as well as why the element is so important to our lives.

• 

  Molecular Motion, Density, Physical Properties, Density, Gas Laws, Ideal Gas, Temperature, Pressure, Volume | Middle School, High School

  Simulation: Density

  The simulation for the September 2015 issue allows students to investigate the effect of changing variables on both the volume and the density of a solid, a liquid, and a gas sample. Students will analyze the different states of matter at the particle level as well as quantitatively.
