Objectives
By
the end of this project, students should be able to
Explain the basic structure of an atom, including location of nucleus, neutrons, protons and electrons.
Collect and understand basic information pertaining to a specific element, including such things as boiling point, melting point, element classification and origin of element name.
Create an atomic model that replicates the atomic structure for a selected element
Successfully use the Aurasma App to create an informational video
Chemistry Topics
This project supports students’ understanding of
Atomic Structure
Model of the Atom
Periodic Table
Elements
Time
Teacher Preparation: minimal
Lesson: 2-3 block classes
Materials
iPod (or any app enabled device)
Internet accessible device for research
Student supplied materials to construct atom (i.e. cotton balls, pipe cleaners, construction paper)
Safety
No specific safety precautions need to be observed for this activity.
Teacher Notes
Print student sign-up sheet (to select element).
Teacher should be familiar with the Aurasma app prior to the activity.
Aurasma app needs to be installed and verified on all devices prior to the start of the activity.
The teacher should review how to use the Aurasma App with the class prior to beginning the project.
Students need to know how to record video using a mobile device.
Teacher should distribute rubric prior to activity.
Students should have basic knowledge of atomic structure as well as the Bohr Model prior to completing this project. Anther models that may want to be considered for this project is the electron cloud model.
Differentiation: Teacher can extend time period if needed. Heterogeneous grouping of students is suggested.
I suggest using 2-3 days for this project:
Day 1: Research selected element using worksheet. Record student research using iPod.
Day 2/3: Access research from other group and create atomic model using student-supplied materials.

For the Student
Lesson
Augmented Reality and the Atomic Model
Background
An atom is the smallest particle of an element that has the chemical properties of that element. An atom is the basic unit of matter and is too small to be seen with an ordinary microscope. Atoms combine in various ways to make up the substances we encounter every day. From the 19th century until today, a number of scientists have contributed to the atomic theory. The current model of the atoms shows electrons, which are negatively charged, move within a region around a positively charged nucleus. This region is known as the electron cloud. The nucleus contains neutrons, which have no charge, and protons with have a positive charge.
Prelab Questions
Explain how the number of electrons relates to the number of protons in an atom.
Explain the difference between atomic number and mass number.
Objective
Construct a model that replicates the atomic structure for a selected element from the periodic table.
Procedure
PART 1:
With a partner, select one common element to research from the periodic table.
Use an internet accessible device to research the chosen element. You will complete the Fact Sheet for collecting information.
Use the camera app to record a video presenting your research.
Open the Aurasma app. Upload your video.
Take a picture of your element on the periodic table to be used as the trigger image.
PART 2:
Open the Aurasma App. Scan a DIFFERENT element’s trigger image. View the student submitted video. Record data using your fact sheet.
Construct a Bohr model of the atom that replicates the atomic structure for the selected element. **Review rubric before beginning**
