Within this lab, students will be able to get a hands on experience with understanding Isotopes. Students will weigh out a variety of Oreo's. Even though they are the same element 'Oreo' They have different weights. The different weights occur because they are using different versions of Oreo's; Oreo Minis, Oreo Thins, Oreo Double Stuffed, and Oreo Regular.
Through this lab, they are able to experience what is meant with the term atomic mass. Once they weight the individual Oreo's, they are given a number of how many of each exist. From there, they are able to calculate atomic mass of the Oreo's.
The lab activity ends with questions that reinforce the main idea of the activity
Oreo Double Stuff
When coming up with this lab, I chose an item that is easy to buy in large quantities for a decent price! If you are unable to purchase Oreo, you can find an alternative resource and edit the download as needed.
