MOLECULAR GEOMETRY - ORIGAMI
If you teach chemistry or physical science, you know that many students struggle with concepts like molecular shapes, bond angles, and polarity. This is largely due to the abstract nature of the topic and the need to envision three-dimensional shapes generally conveyed two dimensionally. This activity will help your students to understand the intricacies of this challenging subject in a fun and creative way while promoting their ability to think abstractly at the same time.
This activity includes carefully designed templates for constructing each of the five electron domain geometries that are key to understanding the fundamentals of molecular geometry. These templates can be printed on regular paper or thicker card-stock preferably, then cut out, folded and glued into beautiful decorations for around the house or used a ‘chemis-tree’ ornaments. These models can be used in future classroom activities and summary worksheets are provided.

In general, Zip Labs are science and math activities broken down into ‘horizontal and vertical’ educational increments. By ‘horizontal’ increments I mean each activity can be completed in a minimum of 60 minutes. However, the teacher, and/or student may choose to extend the activity over a longer time period or even days. By ‘vertical’ increments I mean each activity is broken down into segments according to grade and difficulty level. So teachers and/or students can decide where to start and how far to go with the topic.
Each Zip Lab includes potentially much more than any teacher will use at the particular grade level he or she may teach. However, it is my hope that teachers, and students, at lower grade levels will gain valuable insight by looking ahead to see how their teaching/learning will be applied in the future. While teachers and students at higher grade levels can reflect on topics that they should have learned in earlier grades. It is my hope that students see their education as a continuum rather than a series of disconnected and random topics.
Zip Labs include diagrams and illustrations that I hope are appealing to a wide range of ages. However, teachers can choose to omit them if they like.

Chemistry, Physical Sciences, and College-Level Classes: What you get…
Activity cover sheet (optional)
Model templates: linear, trigonal planar, tetrahedral, trigonal bipyramid, octahedral
Pre and Post-Lab write up worksheet(s)
This unit activity meets or exceeds 21st Century and STEM learning expectations, and Common Core learning outcomes. Note: although ZIP-labs fulfill many CCSS specific CCS standards are not listed because ZIP-labs are designed to be used over many graded levels so the specific CCSS may be different depending upon these factors. For a list of CCSS in your state please visit- www.corestandards.org
New – Integrated Holistic QPA, (that’s Quality Performance Assessment) created by me! This activity requires NO RUBRICS! The rubric is integrated into the activity itself. Much less work for you and far more meaningful to your students.
