Atom Building Project



Here’s your chance to let your creative juices flow! In order to put everything together you have learned  about atoms, you will research an element of your choice and make both a presentation and an atom model. You will be required to use common household and/or craft materials to create atom parts such as protons, neutrons, and electrons.


Use any material you want as long as it’s safe and within reason!  There is no need to buy materials – just use things you find around the house (styrofoam, light clay, paper mache, paperclips, foil, paper, etc.).  Please avoid food items that will cause odour and rot later in time.  


Basic Guidelines & Expectations:


Research and Presentation:


  1. You can choose any element up #36 Krypton (realize this will mean a lot of protons, neutrons, and electrons).

  2. Use the computers to find the following information about your element

    1. Physical characteristics: Name, atomic number, atomic mass, number of protons, neutrons, and electrons

    2. Appearance and location: What it looks like and where it is found on earth

    3. History: past uses, who discovered it, when, how, where the name comes from

    4. Temperature: Melting point, boiling point, state at room temperature

    5. Uses today: Current uses and properties

    6. Cool stuff: 3 other interesting facts

  1. Create a presentation online about your element. As a minimum, create a google slideshow with each separate piece of information on a different slide. Include a picture or video relevant to the information on each slide. Include a title slide with your name and period.



  1. Your model should be about the size of a sheet of printer paper.  Make sure that your final product has the ability to be hung from the ceiling (paperclips and fishing line can be made available upon request).   Size and weight should be considered – nothing too big or heavy! Your model should use different colors and/or types of materials to represent each of the 3 major subatomic particles (protons, neutrons, and electrons). If you use beads to represent the protons, you should use a different material/color to represent the neutrons, and a third to represent the electrons. Your model should have the correct number of electrons, protons, and neutrons present.  Use your periodic table and ask me if you have questions. You will need to do research either on the internet or in a book to determine the positions of electrons for your element (all electrons are orbiting outside of the nucleus, but amount of electrons in each “orbital” is different).


  1. Your model must also include an attached information tag that clearly identifies the following (as shown below):

Side 1                Side 2





Name _________________________________        Element ____________________________










The number of protons, neutrons and electrons are correct.

There is an error in ONE of the atom particle totals

There is an error in TWO of the atom particle totals.

All three atom particle totals are incorrect.


The model includes at least 3 different materials and is very neatly crafted and organized.

The model includes at least 2 different materials and is neatly crafted and organized.

The model includes at least 1 different material but lacks creativity or organization.

Serious lack of creativity or organization.  Model does not use any materials.


All required information is present and correct.

The information on the card is very organized, easy to read and clearly identified/labeled

There are 1-2 errors in the required information. The information on the card is generally organized, readable and labeled

There are 3-4 errors in the required information.The information card is lacking in one of the above areas

There are 5 or more information errors.The information card is not organized, not easy to read and not clearly labeled.





4 (independant)





Student clearly knows their chosen element on a deep level. Student demonstrates exceptional understanding and effort.

All the required information is presented and correct. Student demonstrates expected understanding and effort

Missing 1-2 pieces of required information. Student demonstrates basic understanding and effort.

Missing multiple pieces of information. Information is not correct or clear. Student does not demonstrate basic understanding


Presentation is connected and interesting. Student tells a “story” with their presentation. Peers are engaged in the presentation.

Presentation is connected and interesting.

Presentation is nt engaging and is not well prepared.

Student clearly presented information that they do not understand.
