Classroom Resources: Chemistry Basics
51 – 63 of 63 Classroom Resources
Density, Physical Properties, Identifying an Unknown, Accuracy, Error Analysis | High School, Middle School
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.
Density, Review | High School, Middle School
In this activity, students solve problems on a series of sheets shared in a group.The activity can be extended beyond the topics of temperature and density. This lesson accompanies an article in Chemistry Solutions.
Observations, Density, Sublimation, Phase Changes, Physical Change, Temperature | Middle School
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.
Observations, Density, Interdisciplinary, Scientific Method | Middle School, Elementary School
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.
Separating Mixtures, Density, Mixtures, Chemical Change, Intermolecular Forces, Physical Change, Intermolecular Forces | Middle School
In this lab, students will consider and utilize various separation techniques to purify and reclaim used motor oil.
Density, Physical Properties, Melting Point, Freezing Point, Phase Changes, Physical Change, Molecular Motion, Freezing | Elementary School
In this lesson, students investigate how the density and therefore the volume, of water changes when it freezes.
Density, Melting Point, Inferences, Elements, Periodic Table, Matter, Chemical Properties | Elementary School
In this lesson, students will make measurements, calculations, and inferences to help solve a mystery about the identity of an unknown metal.
Observations, Density, Chemical Change, Density, Combustion, Chemical Change | Elementary School, Middle School
In this demonstration, students will observe a reaction between baking soda and vinegar in the presence of a burning candle. 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 candle to extinguish. Students will analyze the outcome and compare the presence of the gases in the container and make determinations about the densities of each.
Density, Chemical Change, Density, Chemical Change | Elementary School, Middle School, High School
In this demonstration, students will observe a chemical reaction, and see how the product can be used to extinguish a fire.
Observations, Density, Mixtures, Chemical Change, Chemical Change, Physical Change, Acid Base Reactions, Mixtures | Elementary School
In this lab, students create a mixture of oil, water and food coloring, and then add an Alka-Seltzer tablet, to create a homemade lava lamp. Student will record their observations during each step of the process and answer follow-up questions about the chemical and physical changes that took place.
Observations, Density, Physical Properties, Introduction, Mixtures | Elementary School
In this two-part lesson, students will learn about density through a teacher-led demonstration and a hands-on activity. The demonstration will give students the opportunity to observe the formation of a density tower made from common drinks. Students will then create their own density tower using simple ingredients, and then further investigate differences in density when solid objects are added to the tower.
Observations, Density, Physical Properties, Introduction | Elementary School
In this activity, students investigate whether certain materials will sink or float in water. Students will also explore how the shape of an object can affect its volume and density.
Observations, Density, Physical Properties, Mixtures, Mixtures | Elementary School
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.
