STEM videos geared towards High School students

This experiment highlights the importance of water purification systems and the industrial purification process. The chemistry involved in flocculation and removal of dissolved nutrients is discussed. The ecological impact of algal blooms is also discussed and how this ultimately relates back to water purification and prevention of pollution. Students will perform chemical reactions to understand the purification processes.

Skill Level: Beginner

Students will learn about the gases that erupt from volcanoes, and the volcanologists who study them. They will produce carbon dioxide and examine the chemistry and stoichiometry behind the reaction.

Skill Level: Beginner

In this experiment, students will learn about the difference between precipitation due to solubility constraints and precipitation due to a chemical reaction. They will explore various precipitation reactions and learn about their applications in water purification systems. Finally, they will also learn about why the Statue of Liberty has turned different colors!

Skill Level: Beginner

Students will expand on their knowledge of pH and apply this to understanding how acid rain and greenhouse gasses affect the Earth's water supply. They will learn how botanists and marine chemists study the pH changes in soil and water sources and why pH is so important in our ecosystem.

Skill Level: Beginner

Students will learn how simple chemical reactions that cause temperature change can be used for practical applications. They will see how engineers and scientists have converted thermodynamic principles into commercial products. Students will investigate the specific reactions that lead to these temperature changes and then create their own solution to developing a thermo-neutral reaction.

Skill Level: Beginner

Students will examine the germination and growth of plants and test whether a genetic mutation resulting in dwarfism is due to specific genetic mutation resulting in a deficiency of a plant growth hormone (gibberellic acid (GA)). Students will plant and tend the growth of both Standard and Rosette (with mutation for dwarfism) forms of Brassica Rapa. Following germination and initial growth of the plants, students will apply a solution of GA to the leaves and evaluate any effect on the growth and development of both dwarf and standard plants.



Los estudiantes examinarán la germinación y el crecimiento de las plantas y probarán si una mutación genética que resulta en enanismo se debe a una mutación genética específica que resulta en una deficiencia de una hormona de crecimiento vegetal (ácido giberélico (GA)). Los estudiantes plantarán y cuidarán el crecimiento de las formas Standard y Rosette (con mutación por enanismo) de Brassica Rapa. Después de la germinación y el crecimiento inicial de las plantas, los estudiantes aplicarán una solución de GA a las hojas y evaluarán cualquier efecto sobre el crecimiento y desarrollo de plantas enanas y estándar.

Skill Level: Beginner

Students will learn about pH and acid-base reactions. They will investigate pH changes and learn about various techniques used to analyze pH.

Skill Level: Beginner

The chemistry of luminol will be explored. Students will make up solutions of various concentrations and investigate the chemistry of the reaction to generate light without heat. Industrial applications (glow sticks and forensics) of this experiment will also be discussed.

Skill Level: Beginner

This experiment serves as an introduction to, or reinforcement of concepts relating to measurements. Through a series of investigations, students will become more familiar with different tools that are used by scientists, as well as everyday household items that are designed specifically for measuring.
