Looking for a ready-to-use activity that saves the day when you need an emergency sub plan? This editable, Google Classroom–ready resource is the perfect no-prep way for students to practice the steps of the scientific method in a fun and relatable way.

In this activity, students explore The Cookie Dunk Experiment — a scenario where Jordan tests which type of cookie lasts the longest when dunked in milk. Students work step-by-step through the scientific method:

• Identify the problem & testable question
  
• Make observations
  
• Form a hypothesis
  
• Identify variables (independent, dependent, controlled)
  
• Analyze real data from cookie trials
  
• Create a column chart
  
• Draw a conclusion using C-E-R (Claim, Evidence, Reasoning)
  

Everything is structured so a substitute teacher (or you, on a busy day) can run the lesson with ease. Students are guided through slides and prompts, and an answer key is included for quick grading or sub reference.

✅ Why teachers love it:

• Perfect as an emergency sub plan
  
• 100% editable so you can adapt it to your class needs
  
• Works in Google Slides (assign digitally) or print-and-go
  
• Engaging scenario that students instantly connect with (cookies + milk = built-in interest!)
  
• Supports middle school science standards for experimental design & scientific method
  

🎯 Best For:

• Grades 5–8 science
  
• Emergency sub plans
  
• Scientific method review
  
• Low-prep, high-engagement lessons
  

✨ Save yourself the stress — this resource gives you peace of mind knowing you always have a backup plan ready to go. Students will stay on task, practice critical science skills, and actually enjoy the process!
