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.

Lab: Over the Counter Drugs
In this lab, students will do some research about common over the counter drugs and then carry out some chemical tests to learn more about their composition. They will then identify an unknown drug sample.
-
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.
-
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.
