Density, Density, Chemical Change, Observations, Chemical Change, Combustion | Elementary School, Middle School
Demonstration: Investigating Gas Density
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.

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.
-
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.

Density, Density | 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.
-
Observations, Mixtures, Density, Physical Properties, Mixture | 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.
-
Density | High School
Lab: Colors of the Rainbow
In this lab, students will practice density calculations and put their calculations to test by creating their own density column.
