  • StandardsNEW

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:

  • Enzymes take substrate and make product
  • Enzymes lower the activation energy of a reaction
  • Enzymes speed up reaction rates
  • Enzymes are specific to their substrate
  • Reaction rates begin high, but drop to zero as the substrate runs out
  • Higher enzyme concentration leads to faster reaction rate

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!

This lab pairs perfectly with the Enzyme Hands On Lesson Plans and Doodle Notes from Science of Curiosity!

NGSSHS-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. Emphasis is on student reasoning that focuses on the number and energy of collisions between molecules. Assessment is limited to simple reactions in which there are only two reactants; evidence from temperature, concentration, and rate data; and qualitative relationships between rate and temperature.
