    Activity: Physical Properties

    In this activity, students will play a game to review topics relating to physical properties of matter, including mixtures, states of matter, and gas laws. They will be prompted with questions in a PowerPoint and they will use white boards to communicate their answers.

  • Physical Properties, Mixtures, Solubility, Melting Point, Freezing Point, Solute & Solvent, Intermolecular Forces, Polarity, Molecular Structure, Intermolecular Forces, Boiling Point, Lewis Structures, Mixtures, Intramolecular Forces, Graphing | High School

    Lab: Physical Properties (High School)

    In this lesson, students investigate how intermolecular forces effect physical properties by investigating substances’ melting points as well as solubility.

  • Physical Properties, Heat, Specific Heat, Temperature, Scientific Method, Experimental Design | Middle School, High 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, Physical Properties, Identifying an Unknown, Accuracy, Error Analysis | Middle School, High 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.

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

    Lab: Periodic Table Trends

    In this lesson, students will investigate trends of the periodic table.

  • Physical Properties, Polymers, Polymers, Molecular Structure | High School

    Activity: Molecular Spaghetti

    In this activity, students will discover how the entanglement in cooked spaghetti depends on the length of the spaghetti strands and relate this discovery to polymeric materials.

  • Observations, Density, Physical Properties, Mixtures, Mixtures | Elementary School

    Activity: Color-Works in a Jar

    Students will be using three ingredients to create a liquid color-works mixture in a jar. This is a fun chemistry project to do with young elementary students around the 4th of July or New Year’s Eve to get the children excited about fireworks.

  • Physical Properties, Concentration, Colligative Properties, Boiling Point, Accuracy, Graphing, Error Analysis, Boiling Point Elevation, Molality | High School

    Lab: Changing Water's Boiling Point

    In this lab, students will explore colligative properties in a quantitative approach. They will measure the effect of increasing the molality of a salt solution on the solution’s boiling point, and they will graph their data and use the slope of the line of best fit to calculate the boiling point elevation constant of water. There are three versions of the lab, some of which provide more structure and guidance and others of which are more student-driven.

  • Physical Properties, Gas Laws, Pressure, Ideal Gas, Volume, Graphing, Error Analysis | High School

    Lab: Boyle's Law

    In this lab, students stack books on top of a closed syringe and use the volume change to determine the mass of the books.

  • Observations, Physical Properties, Introduction, Polymers | Elementary School

    Activity: Bouncy Ball

    In this activity, students explore the chemical reaction between borax and glue, creating a polymer ball. The properties of the polymer ball will be analyzed and compared to a store bought bouncy ball.

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

    Lab: As Easy as Pie

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

  • Physical Properties, Mixtures, 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.

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