Slime In the Bag Inquiry, Laboratory Activity

In this fun activity, students are challenged to balance chemical equations, perform mole calculations, determine limiting reagents, and understand stoichiometry.

  • Teacher and Student-Led Activities
  • Students Practice Stoichiometry
  • For Grades 6-12
  • Material for 90 preparations
  • Estimated Lab Time: 40 minutes
The activity uses chemistry to determine the exact amount of three ingredients to place in a zip-lock bag, so it fills up its maximum size without bursting. Students watch the fruits of their labor to see if the bag fills up or pops open. The Demonstration Kit is a teacher-led inquiry activity and contains enough material to repeat the demonstration about 20 times. The Laboratory Activity Kit is a student-lead inquiry activity and contains enough material to repeat the demonstration about 60 times.

Using stoichiometry, these activities teach students how to determine the volume of a plastic bag, the molecular mass of two solids being reacted, and the number of moles of gas needed to fill the volume of the bag. Once the students make these determinations, the teacher or students can measure it out and try the experiment to see if the bag becomes fully inflated without popping open.

Ordering information: This kit includes citric acid, baking soda, and plastic bags. Water, a graduated cylinder, a spatula, and an analytical balance (0.001 g) are not included.
