This super fun activity helps students experience how reaction rate changes over time. Scissors become enzymes (Strawase enzymes!), and straws become substrates!
Lab focuses on these characteristics of enzymes:
Very simple set up! Students work in pairs, each pair needs about 30 plastic bendy straws and one pair of scissors.
Students will take individual data, then class data, and graph it to see the change in reaction rate over time. An additional graph guides students to see the relationship between reaction rate and enzyme concentration.
Full three page teacher guide provides instructions for set up and how to guide students though the lab. Includes how to introduce the lab with a short activity demonstrating how enzymes lower the activation energy of a reaction!
Student pages include point values for each question, with total points per page at the bottom - so you do not have to figure out how to grade it! Plus, a link to a full answer key!
