This is a fun lab for high school students that are studying atoms. During this activity, students will rotate to lab stations and determine the atom that is being represented by the candies in a bag.

This lab activity includes:

*Teacher Directions

*Student Lab Sheet

*Lab Key

*Sample Problem

Supplies needed for setup:

*8 snack size (or larger) zipper storage bags

*86 Nerds or similar candies

*86 M&M’s or similar candies

*91 Skittles or similar candies

*Clear tape

Students will need:

*A periodic table that lists the element name, atomic number and atomic mass of all the elements

*A description of the reactivity of the elements

*A description of the characteristics of the periodic table families

Students will need to have an understanding of the parts of an atom, ions, isotopes, Bohr models, and the families and periods on the periodic table. There is a sample problem included for the teacher to help students review the concepts needed. This lab is designed to address high school Next Generation Science Standard* (NGSS*) HS-PS1-1. Depending on your students’ knowledge of atoms and the other portions of the lab, this activity can take 40-60 minutes to complete.

to see state-specific standards (only available in the US).
Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms. Examples of properties that could be predicted from patterns could include reactivity of metals, types of bonds formed, numbers of bonds formed, and reactions with oxygen. Assessment is limited to main group elements. Assessment does not include quantitative understanding of ionization energy beyond relative trends.
