Planaria Regeneration Kit

$10.25 - $90.25

  • Enables students to plan and carry out an investigation on tissue regeneration in planaria to build a predictive model for regeneration patterns based on stem cell locations.
  • High school laboratory investigation with enough materials for 10 lab groups.
  • Carolina Kits 3D®—Labs that use phenomena to support NGSS and 3-dimensional instruction.

Description

Starfish regeneration introduces the investigative phenomenon of regeneration in animals. Over the course of this multi-week lab, students gather evidence as they observe and identify patterns in the regrowth of planarians that have undergone several different controlled injuries. After compiling evidence of planaria regeneration from observations by the entire class, student groups revisit their original hypotheses regarding the driving question. Note: Order the kit with the perishable materials included or with a voucher to request perishables later at your convenience. Contact us or return the voucher to request delivery of perishable materials.

Time Requirement
270 minutes over 2 to 6 weeks: 1 lab period to set up the experiment; 10 to 20 minutes a lab period to collect data over the next 2 to 6 weeks; and then 2 to 3 lab periods for discussion and assessment.

Digital Resources
Includes 1-year access to digital resources that support 3-dimensional instruction for NGSS. Digital resources may include a teacher manual and student guide, pre-lab activities and setup videos, phenomenon videos, simulations, and post-lab analysis and assessments.

Learning Objectives

  • Formulate directional hypotheses regarding planarian regeneration patterns after certain cuts are performed.
  • Collect data to document regeneration changes in a planarian.
  • Summarize class data by creating a list of regeneration patterns observed.
  • Apply observations of regeneration patterns to the prediction of neoblast locations and of cut patterns that are likely to result in no regeneration.

Prerequisite Knowledge and Skills
Students need a knowledge of the process of mitosis and experience performing experiments with living organisms.
