51 – 71 of 71 Classroom Resources
Sublimation, Density, Observations | High School, Middle School
Lab: Dry Ice (High School)
In this lab, students perform several small experiments using dry ice and record their observations.
Density, Observations, Interdisciplinary, Scientific Method | Middle School, Elementary School
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.
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.
Chemical Change, Chemical Change, Observations | High School, Middle School
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
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
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.
Observations | Middle School, Elementary School, High School
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.
Density, Density, Chemical Change, Observations, Inferences | High School, Middle School
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.
Balancing Equations, Chemical Change, Observations | High School, Middle School
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
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
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, Acid, Chemical Change | Middle School
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
Activity: Black Box
In this activity, students will experience how scientists carry out a scientific investigation through inquiry.
Chemical Change, Classification of Reactions, Oxidation, Reduction, Redox Reaction, Electrons, Electron Transfer, Ions, Observations, Inferences, Chemical Change | Middle School
Lesson Plan: One Tube Reaction
In this lesson, students will observe a chemical change involving oxidation and reduction.
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.
Observations, Combustion, Phase Changes, Experimental Design, Scientific Method | High School, Middle School
Lab: Observing a Candle
In this lab, students accumulate observations of a candle including a look at the combustion reaction's reactants and products.
Conservation of Mass, Measurements, Conservation of Mass, Chemical Change, Observations, Physical Change, Chemical Change | High School, Middle School
Lab: Mass & Change
In this lab, students will use unified particle pictures of solid, liquid, and gas to explain the law of conservation of mass after carrying out various experiments.
Physical Change, Mixtures, Observations | High School, Middle School
Activity: Magic Bubble
In this lesson, students will create and interpret particle diagrams that represent elements and compounds at the molecular level. They will also describe the process of dissolving and create particle diagrams that represent mixtures at the molecular level.
Chemical Change, Observations, Acids & Bases, Chemical Change, Mixtures | Elementary School, Middle School, High School
Demonstration: Inflating a Balloon with Chemistry
In this demonstration, the teacher will perform a reaction between acetic acid (vinegar) and sodium bicarbonate (baking soda) in order to inflate a balloon and to introduce the concept of a chemical reaction to students. Students will observe the reaction, and identify indicators of chemical change as well as discuss the different types of matter that are involved.
Density, Observations, Inferences, Mixtures, Mixtures | Middle School, High School
Demonstration: Density Tubes
In this demonstration, students will have the opportunity to observe and analyze the density of a solution. Students will interpret their observations as they compare the density of the solution with plastic components.
