In this activity students will observe cohesion and adhesion properties of molecules that make up water. This will be done by observing the almost magical effect of water traveling across a string.

 

In this activity students will observe the capillary action of water that will further observe the adhesion and cohesion interaction of the water molecules. In this activity, students will observe this phenomena through the migration of water moving from one cup to another.

 

In this activity students will observe the interaction of gas molecules that lead to the properties of gas. Students will be able to alter how many molecules present and the amount of pressure and temperature applied.

Chromatography is a common technique utilized by chemists to break down a compound chemical into its components. In this activity, students will perform chromatography experiments on candy to determine what color of dyes were utilized to form the color of the candy.

 

In this activity, students will create their own molecules from atoms. Students will understand the difference between atoms and molecules. In addition, they will understand how a combination of atoms can form different molecules.

 

In this simulation activity, students will observe molecular models of different states of matter. Students will then observe the interaction of molecules when phase changes occur between states at different temperatures and pressures.

pH indicators are an important tool used by many engineers to test the quality of water. In this activity students will extract a pigment from red cabbage that can be used as a pH indicator. Students will then test this indicator on different solutions to observe if they are acidic or basic.

 

Balancing of chemical equations is an important aspect toward understanding the amount of atoms present in a reaction. This can be a tricky process where this activity helps students practice how to balance equations with the help of simulated particles and scales.

 

In this activity, students will explore enzymes in the form of catalase. Students will be able to understand how enzymes are utilized as a catalyst to speed up chemical reactions by observing different reactions of hydrogen peroxide.
