By the end of this activity, students should be able to
- Identify and locate the differences in the laboratory scenes provided.
This activity supports students’ understanding of
Teacher Preparation: 5 minutes
Lesson: 10-15 minutes
- Printed copies of image 1 and image 2
- Answer key
- No specific safety precautions need to be observed for this activity.
- This is a ChemFun activity, published with the May 2016 issue of Chemistry Solutions.
- Students should be given printed copies of both images (download each in order to print).
- Students should compare the images and attempt to identify 22 differences between the images.
- Teachers may want to have younger students work in pairs, and older students work independently.
- The answer key is available for teachers to download and use for reference.
- This activity can be used at all levels of K-12 chemistry.
- At higher levels, this could be a fun activity for students to complete after they have finished an assessment.
- At lower levels, this could be used to challenge student’s observation skills.
- Please note that this activity was developed in the spirit of fun. We hope that it provides an opportunity for an engaging, but light-hearted experience for K-12 students.
