Jello Enzyme Experiment Procedures

The video tutorial guides students through a jello enzyme lab experiment. It begins with an introduction to the materials needed, followed by detailed instructions on setting up the jello dish and creating wells using a straw. Students then measure the initial diameters of the wells, fill them with various solutions, and observe changes after one to two nights. The final step involves measuring the wells again to determine which solutions contain protease enzymes, as indicated by changes in well size. The lab aims to teach students about enzyme activity and data recording.

What materials are required for the Jello Enzyme Lab?

• A jellyfield petri dish, a piece of straw, a toothpick, a pen, and a metric ruler

• A jellyfield petri dish, a piece of straw, a toothpick, a sharpie, and a yardstick

• A jellyfield petri dish, a spoon, a knife, a sharpie, and a metric ruler

• A jellyfield petri dish, a piece of straw, a toothpick, a sharpie, and a metric ruler

What is the first step in preparing the jello petri dish?

• Placing the jello dish in the refrigerator

• Measuring the diameter of the wells

• Tracing the pie sections with a sharpie

• Filling the wells with solutions

How do you create wells in the jello?

• Using a knife to cut out sections

• Using a pen to poke holes

• Using a straw to make holes

• Using a spoon to scoop out jello

What is the purpose of measuring the diameter of the wells?

• To record the initial size for comparison

• To determine the amount of solution needed

• To calculate the volume of jello

• To ensure they are all different sizes

Which solution acts as a control in the experiment?

• Pineapple juice

• Dawn detergent

• Water

• Meat tenderizer

Why should the jello plugs not be consumed?

• They are too small to eat

• They contain chemicals due to pH changes

• They are needed for further experiments

• They are not tasty

What should you do after filling the wells with solutions?

• Place the dish in the refrigerator

• Mix the solutions together

• Immediately measure the diameter again

• Leave it on the lab table for one to two nights

What is the next step after observing the results?

• Add more solutions to the wells

• Eat the jello

• Measure the diameter of the wells again

• Throw away the jello dish

What does an increase in well diameter indicate?

• The solution evaporated

• The jello melted

• The jello absorbed water

• The presence of protease enzymes

What is the role of protease enzymes in this experiment?

• To solidify the jello

• To break down proteins in the jello

• To change the color of the jello

• To increase the pH of the jello
