Exploring Kinetics with Galvanized Coatings—Blended Learning Solution for Chemistry 1-Year Access

Exploring Kinetics with Galvanized Coatings – Blended Learning Solution for Chemistry 1-Year Access
Exploring Kinetics with Galvanized Coatings – Blended Learning Solution for Chemistry 1-Year Access
Do you ever wish you had more time to spend on labs, that your students could be more independent in their progress through experimental procedures and that labs better connected to the things students experience in their lives? Flinn’s blended learning solution kits for chemistry address these questions by thoughtfully combining hands-on chemistry with digital enhancements.

In this lab, students test these effects by removing the galvanized coating with two different acids and comparing the kinetics between them.

Product Details

The term “galvanized” can be seen on everything from nails to washers to roofing sheets, but what does it mean to galvanize something? Galvanized iron is produced by coating iron with a very thin layer of metallic zinc, which protects the underlying iron metal from rust or corrosion. Environmental factors like acid rain or airborne contaminants can affect this coating. In this lab, students test these effects by removing the galvanized coating with two different acids and comparing the kinetics between them.

Complete for 30 students working in pairs.

Individual Flinn blended Learning Solution Kits include experiment supplies and 1 year of digital content access to one lab for 30 users. Digital features include: 

  • Anytime, anywhere digital access to prelab, technique and summary videos that help students focus on understanding core chemical concepts and progress through experiments independently.
  • Digital procedures optimized to work, with embedded assessments and real sample data and enough materials for 24–30 students working in small groups to complete each experiment
  • Unique takes on core chemistry concepts and clear connections to the things students experience in their everyday lives.
  • Virtual reality simulations that place students “inside the beaker” to connect the atomic and macroscopic scales and browser-based simulations that allow students to generate digital emission spectra and pH indicator tables. 
  • Built-in safety training—videos and assessments on pre-lab safety, proper PPE, safety equipment, procedure safety, chemical disposal, hazard recognition and emergency response.

HS-PS1-3. Plan and conduct an investigation to gather evidence to compare the structure of substances at the bulk scale to infer the strength of electrical forces between particles.
HS-PS1-5. Apply scientific principles and evidence to provide an explanation about the effects of changing the temperature or concentration of the reacting particles on the rate at which a reaction occurs.
HS-PS2-6. Communicate scientific and technical information about why the molecular-level structure is important in the functioning of designed materials.
