    In this lab, students perform several small experiments using dry ice and record their observations.

  • Density, Observations, Interdisciplinary, Scientific Method | Middle School, Elementary School

    Access is an AACT member benefit. Lab: Crush's Dilemma

    In this lab, students explore the concept of density. They will examine the density of a plastic sandwich bag compared to water. Students will create their own experiment and investigate factors that affect floating and sinking.

    Access is an AACT member benefit. 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.

  • Chemical Change, Chemical Change, Observations | High School, Middle School

    Access is an AACT member benefit. Lab: Corrosion in Motion

    In this lab, students will expose metal samples to various solutions and observe the amount of corrosion of a period of time.

  • 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

    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.

  • Conservation of Mass, Chemical Change, Chemical Change, Observations | High School, Middle School

    Access is an AACT member benefit. Lab: Conservation of Mass

    In this lab, students perform three simple experiments, recording the mass of a substance before and after a reaction. They then explain how the law of conservation of mass was not violated, even if the mass changed.

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

    Access is an AACT member benefit. Lab: Condensation

    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.

  • Density, Density, Chemical Change, Observations, Inferences | High School, Middle School

    Access is an AACT member benefit. Demonstration: Comparing Gas Density

    In this demonstration, students will observe a reaction between baking soda and vinegar in the presence of a variety of different heights of lit candles. The initial environment has plenty of oxygen present in order to sustain the candle’s flame; however the reaction will produce carbon dioxide which will cause the lit candles to extinguish in order of height. Students will analyze and compare the presence of the gases in the container and make determinations about the densities of each.

  • Observations | Middle School, Elementary School, High School

    Access is an AACT member benefit. Activity: Compare and Contrast

    In this activity, students will use their observation skills to compare and contrast two similar chemistry classroom scenes in order to identify the differences between the two.

  • Balancing Equations, Chemical Change, Observations | High School, Middle School

    Access is an AACT member benefit. Lab: Chemical Reactions & Equations

    In this lesson, students will observe a series of reactions, make observations, and then write balanced chemical equations to chemically describe what they observed.

  • Chemical Change, Observations, Chemical Change, Reaction Rate, Interdisciplinary, Physical Change, Reaction Rate | Middle School

    Access is an AACT member benefit. Lab: Chemical Weathering in Geology

    In this lab, students will explore the differences between erosion, weathering and chemical weathering. They will complete a lab experiment that simulates chemical weathering on 4 different types of rocks. They will also learn how to use the Mohs Hardness Test to analyze the results.

  • Introduction, Inferences, Observations, Scientific Method | High School, Middle School

    Access is an AACT member benefit. Activity: Check Activity

    In this activity, students develop a theory based on evidence they collect from (fake) cancelled checks to come up with a story of how they are related.

  • Chemical Change, Physical Change, Observations, Chemical Change, Interdisciplinary, Chemical Change | Middle School

    Access is an AACT member benefit. Lab: Break It Down!

    In this lab, students will examine the physical and chemical changes that take place within a landfill by composting leftover fruits and vegetables from their lunches. They will also record pH and temperature measurements during the process.

  • Inferences, Observations, Scientific Method | Middle School, High School

    Access is an AACT member benefit. Activity: Black Box

    In this activity, students will experience how scientists carry out a scientific investigation through inquiry.
