What is Temperature?
In this demonstration, students will observe food dye mixing with water at different temperatures.
Demonstration | Density, Observations, Physical Properties | Elementary School
Will it Float?
In this demonstration, students will observe the relationship between the density of a solution and its impact on an object’s ability to float or sink. Uncooked eggs will be placed in a tap water sample and in a salt water solution so that students can make observations and compare the results in order to make a determination regarding the density value for each item.
Demonstration | Pressure, Temperature | Elementary School, Middle School
In this demonstration, students will learn how temperature change affects air pressure, while observing an egg getting sucked into a bottle without being touched!
Lab | Heat, Kinetic Molecular Theory, Temperature, Temperature | High School, Middle School
In this lab, students will investigate the Kinetic Molecular Theory and particle motion while experimenting with a marshmallow. Students will observe how an increase in kinetic energy will cause particles to increase in motion. This concept will be extended into a discussion about additional real world thermal expansion examples.
Demonstration | Chemical Change, Reaction Rate, Reaction Rate | High School, Middle School
Comparing Rates of Reaction
In this demonstration, students observe the effect of temperature, concentration, and particle size on the rate of a chemical reaction.

Cooking with Conversions
In this activity, students will be given a common homemade recipe for German chocolate cake with measurements in English units. They will be asked to convert the English ingredients list to metric units through scientific calculations. Students will also be asked to identify the ingredients as solid, liquid or gas. While reviewing the cooking procedures, students will classify certain steps as containing compounds or mixtures as well as identify whether chemical or physical changes are taking place. The culinary chemistry involved in this lesson should be introduced throughout the activity.
Lab | Chemical Change, Chemical Change, Observations, Oxidation | Elementary School
In this lab students will learn about the chemical reaction, oxidation, using apple wedges. They will apply different substances to a number of apple wedges to determine if these applications have any impact on the oxidation process. Students will also use a control sample so that they compare their results with an apple wedge that has not had any substance added to it. Students will measure and record the time it takes to see the changes to the apple which indicate oxidation. 3-46
