Details

In this experiment, students will expose living yeast cells to three different sugars-glucose, sucrose, and lactose. The yeast cells should begin to utilize the sugars as a food source if they are capable of metabolizing them, and will begin to engage in aerobic respiration and/or fermentation. This activity allows students to understand that yeast may use different options for energy production, with varying degrees of effectiveness. A pH indicator will be used to indirectly determine the effectiveness of the three different sugars as a food source for the yeast. Kit contains an Instruction Manual and enough material for 2 groups of students.

..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.
