INTRODUCTION TO REACTION RATES 

Chemical reactions vary greatly. For example, some chemicals react extremely fast like an explosion, while others, like rusting metal, can react over a long period of time. Understanding the factors that influence the rate of a reaction allows the scientist to speed up or slow down reactions as desired. This kit has been designed to introduce students to the concepts of reaction rates through a series of experiments demonstrating the impact of concentration, heat, surface area and catalysts. Kit contains enough materials for 10 groups. Teacher's manual and Student Study Guide copymasters are included.

What Educators are Saying About Geyer

Justin has been nothing but helpful and professional in my requests for these Boeing Defense requirements. He has been able to answer my questions and concerns quickly, and helped in securing the order that I may have made with another supplier had be not been the value-add that he is to your company. I hope his merit raise this FY was "exceeds expectations".

..I contacted Geyer via email. I had an email back within minutes!.. A back and forth via email sometimes takes days with other companies and customer service doesn’t happen like this very often. When it does, it’s much appreciated. Brett at Geyer was very polite and accommodating!

John C.

The customer service rep went as far as to reach out to the manufacturer of a product to answer my question, and then provided pictures. She really went above and beyond and answered the question thoroughly and gave me exactly the information I was looking for. This entire process was also extremely fast.

I called to ask how to submit a Tax Exempt Certificate for my library and spoke to a real person, no automation or asking me to press a number. He was friendly, helpful and got our Tax Exempt status established immediately.

...I don't think I've ever experienced that level of customer service before, and taking it into consideration along with the quality of their products, I would absolutely recommend Geyer to fellow teachers.
