ATOMIC RADIUS 2nd edition!
Introducing the 2nd edition of this popular lab activity. This version includes a new font, edits, DOK sliders, integrative grading rubrics, options for differentiated classrooms, and more
The Atomic Radius activity is a great lesson intended for chemistry or physical science classes, however it could also be used in math class for a real-world application. This activity is intended for advanced high school and college level classes. Students will calculate the atomic radius of a metal, (suggested aluminum), using experimental data and compare this value to the theoretical value. This lab combines experimental measurement with theoretical models and analogies.
In this lab students will explore the concept of empty space between atoms, (assumed to be spheres), and determine the percent empty space, (approximately 24%!). Your more advanced students may challenge themselves and try to determine the amount of empty space in the atom itself or even in the atom’s nucleus.
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. Also included is a Common Core ‘Depth of Knowledge’ (DOK) and grade level range ‘sliding’ indicator to help students visualize the relevance of their work.
New in this activity, optional QPA, (Quality Performance Assessment) ‘Stamps’ for Competency Based grading as well as differentiated lesson planning!

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.
